+# Contributing to Angular
+
+We would love for you to contribute to Angular and help make it even better than it is today!
+As a contributor, here are the guidelines we would like you to follow:
+
+ - [Code of Conduct](#coc)
+ - [Question or Problem?](#question)
+ - [Issues and Bugs](#issue)
+ - [Feature Requests](#feature)
+ - [Submission Guidelines](#submit)
+ - [Coding Rules](#rules)
+ - [Commit Message Guidelines](#commit)
+ - [Signing the CLA](#cla)
+
+
+## <a name="coc"></a> Code of Conduct
+
+Help us keep Angular open and inclusive.
+Please read and follow our [Code of Conduct][coc].
+
+
+## <a name="question"></a> Got a Question or Problem?
+
+Do not open issues for general support questions as we want to keep GitHub issues for bug reports and feature requests.
+Instead, we recommend using [Stack Overflow](https://stackoverflow.com/questions/tagged/angular) to ask support-related questions. When creating a new question on Stack Overflow, make sure to add the `angular` tag.
+
+Stack Overflow is a much better place to ask questions since:
+
+- there are thousands of people willing to help on Stack Overflow
+- questions and answers stay available for public viewing so your question/answer might help someone else
+- Stack Overflow's voting system assures that the best answers are prominently visible.
+
+To save your and our time, we will systematically close all issues that are requests for general support and redirect people to Stack Overflow.
+
+If you would like to chat about the question in real-time, you can reach out via [our gitter channel][gitter].
+
+
+## <a name="issue"></a> Found a Bug?
+
+If you find a bug in the source code, you can help us by [submitting an issue](#submit-issue) to our [GitHub Repository][github].
+Even better, you can [submit a Pull Request](#submit-pr) with a fix.
+
+
+## <a name="feature"></a> Missing a Feature?
+You can *request* a new feature by [submitting an issue](#submit-issue) to our GitHub Repository.
+If you would like to *implement* a new feature, please consider the size of the change in order to determine the right steps to proceed:
+
+* For a **Major Feature**, first open an issue and outline your proposal so that it can be discussed.
+  This process allows us to better coordinate our efforts, prevent duplication of work, and help you to craft the change so that it is successfully accepted into the project.
+
+  **Note**: Adding a new topic to the documentation, or significantly re-writing a topic, counts as a major feature.
+
+* **Small Features** can be crafted and directly [submitted as a Pull Request](#submit-pr).
+
+
+## <a name="submit"></a> Submission Guidelines
+
+
+### <a name="submit-issue"></a> Submitting an Issue
+
+Before you submit an issue, please search the issue tracker, maybe an issue for your problem already exists and the discussion might inform you of workarounds readily available.
+
+We want to fix all the issues as soon as possible, but before fixing a bug we need to reproduce and confirm it.
+In order to reproduce bugs, we require that you provide a minimal reproduction.
+Having a minimal reproducible scenario gives us a wealth of important information without going back and forth to you with additional questions.
+
+A minimal reproduction allows us to quickly confirm a bug (or point out a coding problem) as well as confirm that we are fixing the right problem.
+
+We require a minimal reproduction to save maintainers' time and ultimately be able to fix more bugs.
+Often, developers find coding problems themselves while preparing a minimal reproduction.
+We understand that sometimes it might be hard to extract essential bits of code from a larger codebase but we really need to isolate the problem before we can fix it.
+
+Unfortunately, we are not able to investigate / fix bugs without a minimal reproduction, so if we don't hear back from you, we are going to close an issue that doesn't have enough info to be reproduced.
+
+You can file new issues by selecting from our [new issue templates](https://github.com/angular/angular/issues/new/choose) and filling out the issue template.
+
+
+### <a name="submit-pr"></a> Submitting a Pull Request (PR)
+
+Before you submit your Pull Request (PR) consider the following guidelines:
+
+1. Search [GitHub](https://github.com/angular/angular/pulls) for an open or closed PR that relates to your submission.
+   You don't want to duplicate existing efforts.
+
+2. Be sure that an issue describes the problem you're fixing, or documents the design for the feature you'd like to add.
+   Discussing the design upfront helps to ensure that we're ready to accept your work.
+
+3. Please sign our [Contributor License Agreement (CLA)](#cla) before sending PRs.
+   We cannot accept code without a signed CLA.
+   Make sure you author all contributed Git commits with email address associated with your CLA signature.
+
+4. Fork the angular/angular repo.
+
+5. Make your changes in a new git branch:
+
+     ```shell
+     git checkout -b my-fix-branch master
+     ```
+
+6. Create your patch, **including appropriate test cases**.
+
+7. Follow our [Coding Rules](#rules).
+
+8. Run the full Angular test suite, as described in the [developer documentation][dev-doc], and ensure that all tests pass.
+
+9. Commit your changes using a descriptive commit message that follows our [commit message conventions](#commit).
+   Adherence to these conventions is necessary because release notes are automatically generated from these messages.
+
+     ```shell
+     git commit -a
+     ```
+    Note: the optional commit `-a` command line option will automatically "add" and "rm" edited files.
+
+10. Push your branch to GitHub:
+
+    ```shell
+    git push origin my-fix-branch
+    ```
+
+11. In GitHub, send a pull request to `angular:master`.
+
+   If we ask for changes via code reviews then:
+
+   * Make the required updates.
+   * Re-run the Angular test suites to ensure tests are still passing.
+   * Rebase your branch and force push to your GitHub repository (this will update your Pull Request):
+
+      ```shell
+      git rebase master -i
+      git push -f
+      ```
+
+That's it! Thank you for your contribution!
+
+
+#### After your pull request is merged
+
+After your pull request is merged, you can safely delete your branch and pull the changes from the main (upstream) repository:
+
+* Delete the remote branch on GitHub either through the GitHub web UI or your local shell as follows:
+
+    ```shell
+    git push origin --delete my-fix-branch
+    ```
+
+* Check out the master branch:
+
+    ```shell
+    git checkout master -f
+    ```
+
+* Delete the local branch:
+
+    ```shell
+    git branch -D my-fix-branch
+    ```
+
+* Update your master with the latest upstream version:
+
+    ```shell
+    git pull --ff upstream master
+    ```
+
+
+## <a name="rules"></a> Coding Rules
+To ensure consistency throughout the source code, keep these rules in mind as you are working:
+
+* All features or bug fixes **must be tested** by one or more specs (unit-tests).
+* All public API methods **must be documented**.
+* We follow [Google's JavaScript Style Guide][js-style-guide], but wrap all code at **100 characters**.
+
+   An automated formatter is available, see [DEVELOPER.md](docs/DEVELOPER.md#clang-format).
+
+
+## <a name="commit"></a> Commit Message Format
+
+*This specification is inspired and supersedes the [AngularJS commit message format][commit-message-format].*
+
+We have very precise rules over how our Git commit messages must be formatted.
+This format leads to **easier to read commit history**.
+
+Each commit message consists of a **header**, a **body**, and a **footer**.
+
+
+```
+<header>
+<BLANK LINE>
+<body>
+<BLANK LINE>
+<footer>
+```
+
+The `header` is mandatory and must conform to the [Commit Message Header](#commit-header) format.
+
+The `body` is mandatory for all commits except for those of scope "docs".
+When the body is required it must be at least 20 characters long.
+
+The `footer` is optional.
+
+Any line of the commit message cannot be longer than 100 characters.
+
+
+#### <a href="commit-header"></a>Commit Message Header
+

+```
+
+The `<type>` and `<summary>` fields are mandatory, the `(<scope>)` field is optional.
+
+
+##### Type
+
+Must be one of the following:
+
+* **build**: Changes that affect the build system or external dependencies (example scopes: gulp, broccoli, npm)
+* **ci**: Changes to our CI configuration files and scripts (example scopes: Circle, BrowserStack, SauceLabs)
+* **docs**: Documentation only changes
+* **feat**: A new feature
+* **fix**: A bug fix
+* **perf**: A code change that improves performance
+* **refactor**: A code change that neither fixes a bug nor adds a feature
+* **style**: Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)
+* **test**: Adding missing tests or correcting existing tests
+
+
+##### Scope
+The scope should be the name of the npm package affected (as perceived by the person reading the changelog generated from commit messages).
+
+The following is the list of supported scopes:
+
+* `animations`
+* `bazel`
+* `benchpress`
+* `common`
+* `compiler`
+* `compiler-cli`
+* `core`
+* `elements`
+* `forms`
+* `http`
+* `language-service`
+* `localize`
+* `platform-browser`
+* `platform-browser-dynamic`
+* `platform-server`
+* `platform-webworker`
+* `platform-webworker-dynamic`
+* `router`
+* `service-worker`
+* `upgrade`
+* `zone.js`
+
+There are currently a few exceptions to the "use package name" rule:
+
+* `packaging`: used for changes that change the npm package layout in all of our packages, e.g. public path changes, package.json changes done to all packages, d.ts file/format changes, changes to bundles, etc.
+
+* `changelog`: used for updating the release notes in CHANGELOG.md
+
+* `dev-infra`: used for dev-infra related changes within the directories /scripts, /tools and /dev-infra
+
+* `docs-infra`: used for docs-app (angular.io) related changes within the /aio directory of the repo
+
+* `migrations`: used for changes to the `ng update` migrations.
+
+* `ngcc`: used for changes to the [Angular Compatibility Compiler](./packages/compiler-cli/ngcc/README.md)
+
+* `ve`: used for changes specific to ViewEngine (legacy compiler/renderer).
+
+* none/empty string: useful for `style`, `test` and `refactor` changes that are done across all packages (e.g. `style: add missing semicolons`) and for docs changes that are not related to a specific package (e.g. `docs: fix typo in tutorial`).
+
+
+##### Summary
+
+Use the summary field to provide a succinct description of the change:
+
+* use the imperative, present tense: "change" not "changed" nor "changes"
+* don't capitalize the first letter
+* no dot (.) at the end
+
+
+#### Commit Message Body
+
+Just as in the summary, use the imperative, present tense: "fix" not "fixed" nor "fixes".
+
+Explain the motivation for the change in the commit message body. This commit message should explain _why_ you are making the change.
+You can include a comparison of the previous behavior with the new behavior in order to illustrate the impact of the change.
+
+
+#### Commit Message Footer
+
+The footer can contain information about breaking changes and is also the place to reference GitHub issues, Jira tickets, and other PRs that this commit closes or is related to.
+
+```
+BREAKING CHANGE: <breaking change summary>
+<BLANK LINE>
+<breaking change description + migration instructions>
+<BLANK LINE>
+<BLANK LINE>
+Fixes #<issue number>
+```
+
+Breaking Change section should start with the phrase "BREAKING CHANGE: " followed by a summary of the breaking change, a blank line, and a detailed description of the breaking change that also includes migration instructions.
+
+
+### Revert commits
+
+If the commit reverts a previous commit, it should begin with `revert: `, followed by the header of the reverted commit.
+
+The content of the commit message body should contain:
+
+- information about the SHA of the commit being reverted in the following format: `This reverts commit <SHA>`,
+- a clear description of the reason for reverting the commit message.

-## <a name="coc"></a> Code of Conduct
+## <a name="coc"></a> Código de conducta
 
-Help us keep Angular open and inclusive.
+Ayúdanos a mantener Angular abierto e inclusivo.
-Please read and follow our [Code of Conduct][coc].
+Por favor lee y sigue nuestro [Código de conducta][coc].
 
 
-## <a name="question"></a> Got a Question or Problem?
+## <a name="question"></a> ¿Tienes alguna pregunta o problema?
 
-Do not open issues for general support questions as we want to keep GitHub issues for bug reports and feature requests.
+No abras *issues* para preguntas de soporte general ya que queremos mantener los *issues* de GitHub para reporte de *bugs* y solicitud de funcionalidades.
-Instead, we recommend using [Stack Overflow](https://stackoverflow.com/questions/tagged/angular) to ask support-related questions. When creating a new question on Stack Overflow, make sure to add the `angular` tag.
+En su lugar, recomendamos utilizar [Stack Overflow](https://stackoverflow.com/questions/tagged/angular) para hacer preguntas relacionadas con soporte. Al crear una nueva pregunta en Stack Overflow, asegúrate de agregar el etiqueta (tag) de `angular`.
 
-Stack Overflow is a much better place to ask questions since:
+Stack Overflow es mucho mejor para hacer preguntas ya que:
 
-- there are thousands of people willing to help on Stack Overflow
+- Hay miles de personas dispuestas a ayudar en preguntas y respuestas de Stack Overflow
-- questions and answers stay available for public viewing so your question/answer might help someone else
+que  permanecen disponibles para el público, por lo que tu pregunta o respuesta podría ayudar a otra persona.
-- Stack Overflow's voting system assures that the best answers are prominently visible.
+- El sistema de votación de Stack Overflow asegura que las mejores respuestas sobresalgan y sean visibles.
 
-To save your and our time, we will systematically close all issues that are requests for general support and redirect people to Stack Overflow.
+Para ahorrar tu tiempo y el nuestro, cerraremos sistemáticamente todos los *issues* que sean solicitudes de soporte general y redirigiremos a las personas a Stack Overflow.
 
-If you would like to chat about the question in real-time, you can reach out via [our Discord server][discord].
+Si deseas chatear sobre alguna pregunta en tiempo real, puedes hacerlo a través de nuestro [canal de Gitter][gitter].
 
 
-## <a name="issue"></a> Found a Bug?
+## <a name="issue"></a> ¿Encontraste un Bug?
 
-If you find a bug in the source code, you can help us by [submitting an issue](#submit-issue) to our [GitHub Repository][github].
+Si encontraste un error en el código fuente, puedes ayudarnos [creando un *issue*](#submit-issue) en nuestro [repositorio de GitHub][github].
-Even better, you can [submit a Pull Request](#submit-pr) with a fix.
+O incluso mejor, puedes [crear un *Pull Request*](#submit-pr) con la solución.
 
 
-## <a name="feature"></a> Missing a Feature?
+## <a name="feature"></a> ¿Falta alguna funcionalidad?
-You can *request* a new feature by [submitting an issue](#submit-issue) to our GitHub Repository.
+Puedes solicitar una nueva funcionalidad [creando un *issue*](#submit-issue) en nuestro repositorio de GitHub.
-If you would like to *implement* a new feature, please consider the size of the change in order to determine the right steps to proceed:
+Si deseas implementar una nueva funcionalidad, por favor considera el tamaño del cambio para determinar los pasos correctos para continuar:
 
-* For a **Major Feature**, first open an issue and outline your proposal so that it can be discussed.
+* Para un **cambio significativo**, primero abre un *issue* y describe tu propuesta para que pueda ser discutida.
-  This process allows us to better coordinate our efforts, prevent duplication of work, and help you to craft the change so that it is successfully accepted into the project.
+  Este proceso nos permite coordinar mejor nuestros esfuerzos, evitar trabajo duplicado y ayudarte a diseñar el cambio para que sea aceptado con éxito en el proyecto.
 
-  **Note**: Adding a new topic to the documentation, or significantly re-writing a topic, counts as a major feature.
+  **Nota**: Agregar un nuevo tema a la documentación o reescribir significativamente un tema, también cuenta como *cambio significativo*.
 
-* **Small Features** can be crafted and directly [submitted as a Pull Request](#submit-pr).
+* **Cambios pequeños** pueden ser elaborados y directamente [creados como un _pull request_](#submit-pr).

-Before you submit an issue, please search the issue tracker, maybe an issue for your problem already exists and the discussion might inform you of workarounds readily available.
+Antes de crear un *issue*, por favor busca en el el *issue tracker*, quizá un *issue* para tu problema ya existe y la discusión puede informarte sobre soluciones alternativas disponibles.
 
-We want to fix all the issues as soon as possible, but before fixing a bug we need to reproduce and confirm it.
+Queremos solucionar todos los problemas lo antes posible, pero antes de corregir un bug necesitamos reproducirlo y confirmarlo.
-In order to reproduce bugs, we require that you provide a minimal reproduction.
+Para reproducir errores, requerimos que proporciones una reproducción mínima.
-Having a minimal reproducible scenario gives us a wealth of important information without going back and forth to you with additional questions.
+Tener un escenario reproducible mínimo nos brinda una gran cantidad de información importante sin tener que ir y venir con preguntas adicionales.
 
-A minimal reproduction allows us to quickly confirm a bug (or point out a coding problem) as well as confirm that we are fixing the right problem.
+Una reproducción mínima nos permite confirmar rápidamente un bug (o señalar un problema de código), así también confirmar que estamos solucionando el problema correcto.
 
-We require a minimal reproduction to save maintainers' time and ultimately be able to fix more bugs.
+Requerimos una reproducción mínima para ahorrar tiempo a los encargados del mantenimiento y en última instancia, poder corregir más bugs.
-Often, developers find coding problems themselves while preparing a minimal reproduction.
+A menudo los desarrolladores encuentran problemas de código mientras preparan una reproducción mínima.
-We understand that sometimes it might be hard to extract essential bits of code from a larger codebase but we really need to isolate the problem before we can fix it.
+Entendemos que a veces puede ser difícil extraer porciones esenciales de código de un código más grande, pero realmente necesitamos aislar el problema antes de poder solucionarlo.
 
-Unfortunately, we are not able to investigate / fix bugs without a minimal reproduction, so if we don't hear back from you, we are going to close an issue that doesn't have enough info to be reproduced.
+Desafortunadamente no podemos investigar/corregir errores sin una reproducción mínima, por lo que si no tenemos tu retroalimentación del bug, vamos a cerrar el *issue* ya que no tiene suficiente información para reproducirse.
 
-You can file new issues by selecting from our [new issue templates](https://github.com/angular/angular/issues/new/choose) and filling out the issue template.
+Puedes presentar nuevos *issues* seleccionando nuestra [plantilla de _issues_](https://github.com/angular/angular/issues/new/choose) y complentando la plantilla.
 
 
-### <a name="submit-pr"></a> Submitting a Pull Request (PR)
+### <a name="submit-pr"></a> Creación de un Pull Requests (PR)
 
-Before you submit your Pull Request (PR) consider the following guidelines:
+Antes de crear tu Pull Request (PR) considera los siguientes lineamientos:
 
-1. Search [GitHub](https://github.com/angular/angular/pulls) for an open or closed PR that relates to your submission.
+1. Busca en [GitHub](https://github.com/angular/angular/pulls) PRs que estén abiertos o cerrados y que estén relacionados con el que vas a crear.
-   You don't want to duplicate existing efforts.
+  No deseas duplicar los esfuerzos existentes.
 
-2. Be sure that an issue describes the problem you're fixing, or documents the design for the feature you'd like to add.
+2. Asegúrate de que el PR describa el problema que estás solucionando o que documente el diseño de la funcionalidad que deseas agregar.
-   Discussing the design upfront helps to ensure that we're ready to accept your work.
+   Discutir el diseño por adelantado ayuda a garantizar que estemos listos para aceptar tu trabajo.
 
-3. Please sign our [Contributor License Agreement (CLA)](#cla) before sending PRs.
+3. Por favor firma nuestro [Acuerdo de Licencia de Colaborador (CLA)](#cla) antes de crear PRs.
-   We cannot accept code without a signed CLA.
+   No podemos aceptar el código sin el Acuerdo de Licencia de Colaborador (CLA) firmado.
-   Make sure you author all contributed Git commits with email address associated with your CLA signature.
+   Asegúrate de crear todas las contribuciones de Git con la dirección de correo electrónico asociada con tu firma del Acuerdo de Licencia de Colaborador (CLA).
 
-4. Fork the angular/angular repo.
+4. Haz *fork* del repositorio angular/angular.
 
-5. Make your changes in a new git branch:
+5. Haz tus cambios en una nueva rama de Git:
 
      ```shell
      git checkout -b my-fix-branch master
      ```
 
-6. Create your patch, **including appropriate test cases**.
+6. Crea tu correción, **incluyendo casos de prueba apropiados**.
 
-7. Follow our [Coding Rules](#rules).
+7. Sigue nuestras [Reglas de código](#rules).
 
-8. Run the full Angular test suite, as described in the [developer documentation][dev-doc], and ensure that all tests pass.
+8. Ejecuta todo el conjunto de pruebas de Angular, tal como está descrito en la [documentación del desarrollador][dev-doc], y asegúrate de que todas las pruebas pasen.
 
-9. Commit your changes using a descriptive commit message that follows our [commit message conventions](#commit).
+9. Crea un commit de tus cambios utilizando un mensaje de commit descriptivo que siga nuestra [convención para el mensaje de los commits](#commit).
-   Adherence to these conventions is necessary because release notes are automatically generated from these messages.
+   Es necesario cumplir con estas convenciones porque las notas de las versiones se generan automáticamente a partir de estos mensajes.
 
      ```shell
-     git commit --all
+     git commit -a
      ```
-    Note: the optional commit `-a` command line option will automatically "add" and "rm" edited files.
+    Nota: la opción de la línea de comandos de Git `-a` automaticamente hará "add" y "rm" a los archivos editados.
 
-10. Push your branch to GitHub:
+10. Haz push de tu rama a GitHub:
 
     ```shell
     git push origin my-fix-branch
     ```
 
-11. In GitHub, send a pull request to `angular:master`.
+11. En GitHub, crea un pull request a `angular:master`.
+
+   Si solicitamos cambios a través de revisiones de código, sigue las siguientes indicaciones:
+
+   * Haz los cambios requeridos.
+   * Ejecuta nuevamente el conjunto de pruebas de Angular para asegurar que todas las pruebas aún están pasando.
+   * Haz rebase de tu rama a la rama master y haz push con la opción `-f` a tu repositorio de Github (esto actualizará tu Pull Request):
+
+      ```shell
+      git rebase master -i
+      git push -f
+      ```
+
+¡Es todo! ¡Muchas gracias por tu contribución!
 
 
-#### Addressing review feedback
+#### Después del merge de tu pull request
 
-If we ask for changes via code reviews then:
+Después de que se hizo merge de tu pull request, puedes eliminar de forma segura tu rama y hacer pull de los cambios del repositorio principal (upstream):
 
-1. Make the required updates to the code.
+* Elimina la rama remota en GitHub a través de la interfaz de usuario web de GitHub o en tu línea de comandos de la siguiente manera:
-
-2. Re-run the Angular test suites to ensure tests are still passing.
-
-3. Create a fixup commit and push to your GitHub repository (this will update your Pull Request):
-
-    ```shell
-    git commit --all --fixup HEAD
-    git push
-    ```
-
-    For more info on working with fixup commits see [here](docs/FIXUP_COMMITS.md).
-
-That's it! Thank you for your contribution!
-
-
-##### Updating the commit message
-
-A reviewer might often suggest changes to a commit message (for example, to add more context for a change or adhere to our [commit message guidelines](#commit)).
-In order to update the commit message of the last commit on your branch:
-
-1. Check out your branch:
-
-    ```shell
-    git checkout my-fix-branch
-    ```
-
-2. Amend the last commit and modify the commit message:
-
-    ```shell
-    git commit --amend
-    ```
-
-3. Push to your GitHub repository:
-
-    ```shell
-    git push --force-with-lease
-    ```
-
-> NOTE:<br />
-> If you need to update the commit message of an earlier commit, you can use `git rebase` in interactive mode.
-> See the [git docs](https://git-scm.com/docs/git-rebase#_interactive_mode) for more details.
-
-
-#### After your pull request is merged
-
-After your pull request is merged, you can safely delete your branch and pull the changes from the main (upstream) repository:
-
-* Delete the remote branch on GitHub either through the GitHub web UI or your local shell as follows:
 
     ```shell
     git push origin --delete my-fix-branch
     ```
 
-* Check out the master branch:
+* Muévete a la rama master:
 
     ```shell
     git checkout master -f
     ```
 
-* Delete the local branch:
+* Elimina tu rama local:
 
     ```shell
     git branch -D my-fix-branch
     ```
 
-* Update your master with the latest upstream version:
+* Actualiza tu rama master con la última versión del fork (upstream):
 
     ```shell
     git pull --ff upstream master
     ```
 
 
-## <a name="rules"></a> Coding Rules
+## <a name="rules"></a> Reglas del código
-To ensure consistency throughout the source code, keep these rules in mind as you are working:
+Para garantizar la coherencia en todo el código fuente, ten en cuenta estas reglas mientras trabajas:
 
-* All features or bug fixes **must be tested** by one or more specs (unit-tests).
+* Todas las funcionalidades o solución de bugs **deben ser probadas** por una o más pruebas (pruebas unitarias).
-* All public API methods **must be documented**.
+* Todos los métodos públicos del API **deben ser documentados**.
-* We follow [Google's JavaScript Style Guide][js-style-guide], but wrap all code at **100 characters**.
+* Seguimos la [guía de estilo JavaScript de Google][js-style-guide], pero cada línea no debe exceder **100 caracteres**.
 
-   An automated formatter is available, see [DEVELOPER.md](docs/DEVELOPER.md#clang-format).
+   Un formateador automatizado está disponible, revisar [DEVELOPER.md](docs/DEVELOPER.md#clang-format).
 
 
-## <a name="commit"></a> Commit Message Format
+## <a name="commit"></a> Formato para el mensaje de los commits
 
-*This specification is inspired and supersedes the [AngularJS commit message format][commit-message-format].*
+*Esta especificación está inspirada y reemplaza el [Formato de mensaje de commits de AngularJS][commit-message-format].*
 
-We have very precise rules over how our Git commit messages must be formatted.
+Tenemos reglas muy precisas sobre cómo deben formatearse nuestros mensajes de los commits de Git.
-This format leads to **easier to read commit history**.
+Este formato permite tener **un historial de commits más facil de leer**.
 
-Each commit message consists of a **header**, a **body**, and a **footer**.
+Cada mensaje de un commit consta del **header**, el **body**, y el **footer**.
 
 
 ```
 <header>
-<BLANK LINE>
+<LINEA VACIA>
 <body>
-<BLANK LINE>
+<LINEA VACIA>
 <footer>
 ```
 
-The `header` is mandatory and must conform to the [Commit Message Header](#commit-header) format.
+El `header` es obligatorio y debe ajustarse al formato del [mensaje del header del commit](#commit-header).
 
-The `body` is mandatory for all commits except for those of scope "docs".
+El `body` es obligatorio para todos los commits excepto los que tenga scope "docs".
-When the body is required it must be at least 20 characters long.
+Cuando el body es requerido debe tener al menos 20 caracteres.
 
-The `footer` is optional.
+El `footer` es opcional.
 
-Any line of the commit message cannot be longer than 100 characters.
+Cualquier línea del mensaje del commit no puede tener más de 100 caracteres.

+La principal tarea para generar los documentos es `yarn docs`. Esto procesará todos los archivos fuente (API y otros), extrayendo la documentación y generando archivos JSON que pueden ser consumidos por el doc-viewer.
-writing guide pages, explains how to use the documentation classes and components, and how to markup sample source code to produce code snippets.
 
-### Generating the complete docs
+### Generación parcial de doc para editores
 
-The main task for generating the docs is `yarn docs`. This will process all the source files (API and other),
+La generación completa de documentos puede llevar hasta un minuto. Eso es demasiado lento para la creación y edición eficiente de documentos.
-extracting the documentation and generating JSON files that can be consumed by the doc-viewer.
 
-### Partial doc generation for editors
+Puedes ealizar pequeños cambios en un editor inteligente que muestre un markdown con formato:
+>En VS Code, _Cmd-K, V_ abre la vista previa de markdown en el panel lateral; _Cmd-B_ alterna la barra izquierda
 
-Full doc generation can take up to one minute. That's too slow for efficient document creation and editing.
+Puedes también mirar los cambios que se muestran correctamente en el doc-viewer
+con un tiempo de ciclo rápido de edición / visualización.
 
-You can make small changes in a smart editor that displays formatted markdown:
+Para este propósito, usa la tarea `yarn docs-watch`, que observa los cambios en los archivos de origen y solo vuelve a procesar los archivos necesarios para generar los documentos relacionados con el archivo que ha cambiado. 
->In VS Code, _Cmd-K, V_ opens markdown preview in side pane; _Cmd-B_ toggles left sidebar
+Dado que esta tarea tiene accesos directos, es mucho más rápido (a menudo menos de 1 segundo) pero no producirá contenido de fidelidad completa. Por ejemplo, los enlaces a otros documentoss y ejemplos de código pueden no mostrarse correctamente. Esto se nota especialmente en los enlaces a otros documentos y en los ejemplos incrustados, que no siempre se representan correctamente.
 
-You also want to see those changes displayed properly in the doc viewer
+La configuración general es la siguiente:
-with a quick, edit/view cycle time.
 
-For this purpose, use the `yarn docs-watch` task, which watches for changes to source files and only
+* Abrir una terminal, estar seguro que las dependencias están instaladas; ejecutar una generación inicial del doc; luego iniciar el doc-viewer:
-re-processes the files necessary to generate the docs that are related to the file that has changed.
-Since this task takes shortcuts, it is much faster (often less than 1 second) but it won't produce full
-fidelity content. For example, links to other docs and code examples may not render correctly. This is
-most particularly noticed in links to other docs and in the embedded examples, which may not always render
-correctly.
-
-The general setup is as follows:
-
-* Open a terminal, ensure the dependencies are installed; run an initial doc generation; then start the doc-viewer:
 
 ```bash
 yarn setup
 yarn start
 ```
 
-* Open a second terminal and start watching the docs
+* Abrir una segunda terminal e iniciar el observador de documentos.
 
 ```bash
 yarn docs-watch
 ```
 
->Alternatively, try the consolidated `serve-and-sync` command that builds, watches and serves in the same terminal window
+>Alternativamente, prueba el comando fusionado `serve-and-sync` que crea, observa y ejecuta en la misma ventana de la terminal
 ```bash
 yarn serve-and-sync
 ```
 
-* Open a browser at https://localhost:4200/ and navigate to the document on which you want to work.
+* Abre un navegador con la siguiente dirección https://localhost:4200/ y navega hasta el documento en el que quieras trabajar.
-You can automatically open the browser by using `yarn start -o` in the first terminal.
+Puedes automáticamente abrir el navegador utilizando `yarn start -o` en la primera terminal.
 
-* Make changes to the page's associated doc or example files. Every time a file is saved, the doc will
+* Realiza cambios en la página de documentación asociada o en los archivos de ejemplo. Cada vez que un archivo es guardado, la documentación se regenerará, la aplicación se reconstruirá y la página se volverá a cargar.

-* If you get a build error complaining about examples or any other odd behavior, be sure to consult

-### Augmenting native elements
+### Aumento de elementos nativos
 
-Native HTML elements capture a number of standard interaction patterns that are important to accessibility.
+Los elementos HTML nativos capturan una serie de patrones de interacción estándar que son importantes para la accesibilidad.
-When authoring Angular components, you should re-use these native elements directly when possible, rather than re-implementing well-supported behaviors.
+Al crear componentes de Angular, deberías reutilizar estos elementos nativos directamente cuando sea posible, en lugar de volver a implementar comportamientos bien soportados.
 
-For example, instead of creating a custom element for a new variety of button, you can create a component that uses an attribute selector with a native `<button>` element.
+Por ejemplo, en lugar de crear un elemento personalizado para un nuevo tipo de botón, puedes crear un componente que use un selector de atributos con un elemento nativo `<button>`.
-This most commonly applies to `<button>` and `<a>`, but can be used with many other types of element.
+Esto se aplica sobre todo a `<button>` y `<a>`, pero se puede usar con muchos otros tipos de elementos.
 
 You can see examples of this pattern in Angular Material: [`MatButton`](https://github.com/angular/components/blob/master/src/material/button/button.ts#L66-L68), [`MatTabNav`](https://github.com/angular/components/blob/master/src/material/tabs/tab-nav-bar/tab-nav-bar.ts#L67), [`MatTable`](https://github.com/angular/components/blob/master/src/material/table/table.ts#L17).
 
-### Using containers for native elements
+### Uso de contenedores para elementos nativos
 
-Sometimes using the appropriate native element requires a container element.
+A veces, para usar el elemento nativo apropiado hace falta un contenedor.
-For example, the native `<input>` element cannot have children, so any custom text entry components need
+Por ejemplo, el elemento nativo `<input>` no puede tener hijos, por lo que cualquier componente de entrada de texto personalizado necesita envolver un `<input>` con elementos adicionales.
-to wrap an `<input>` with additional elements.
-While you might just include the `<input>` in your custom component's template,
-this makes it impossible for users of the component to set arbitrary properties and attributes to the input element.
-Instead, you can create a container component that uses content projection to include the native control in the
-component's API.
 
-You can see [`MatFormField`](https://material.angular.io/components/form-field/overview) as an example of this pattern.
+Si bien puedes incluir el `<input>` en la plantilla de tu componente personalizado,
+esto hace que sea imposible para los usuarios de dicho componente establecer propiedades y atributos arbitrarios para el elemento de entrada.
+En su lugar, puedes crear un componente contenedor que utilice la proyección de contenido para incluir el control nativo en el
+API del componente.
 
-## Case study: Building a custom progress bar
+Puedes consultar [`MatFormField`](https://material.angular.io/components/form-field/overview) para ver un ejemplo de este patrón.
 
-The following example shows how to make a simple progress bar accessible by using host binding to control accessibility-related attributes.
+## Caso práctico: creación de una barra de progreso personalizada
 
-* The component defines an accessibility-enabled element with both the standard HTML attribute `role`, and ARIA attributes. The ARIA attribute `aria-valuenow` is bound to the user's input.
+El siguiente ejemplo muestra cómo hacer que una barra de progreso simple sea accesible utilizando el *host binding* para controlar los atributos relacionados con la accesibilidad.
+
+* El componente define un elemento habilitado para accesibilidad con el atributo HTML estándar `role` y los atributos ARIA. El atributo ARIA `aria-valuenow` está vinculado a la entrada del usuario.
 
    <code-example path="accessibility/src/app/progress-bar.component.ts" header="src/app/progress-bar.component.ts" region="progressbar-component"></code-example>
 
 
-* In the template, the `aria-label` attribute ensures that the control is accessible to screen readers.
+* En la plantilla, el atributo `aria-label` asegura que el control sea accesible para los lectores de pantalla.

+# Ahead-of-time (AOT) compilation
+
+An Angular application consists mainly of components and their HTML templates. Because the components and templates provided by Angular cannot be understood by the browser directly, Angular applications require a compilation process before they can run in a browser.
+
+The Angular [ahead-of-time (AOT) compiler](guide/glossary#aot) converts your Angular HTML and TypeScript code into efficient JavaScript code during the build phase _before_ the browser downloads and runs that code. Compiling your application during the build process provides a faster rendering in the browser.
+
+This guide explains how to specify metadata and apply available compiler options to compile your applications efficiently using the AOT compiler.
+
+<div class="alert is-helpful">
+
+  <a href="https://www.youtube.com/watch?v=anphffaCZrQ">Watch Alex Rickabaugh explain the Angular compiler</a> at AngularConnect 2019.
+
+</div>
+
+{@a why-aot}
+
+Here are some reasons you might want to use AOT.
+
+* *Faster rendering*
+   With AOT, the browser downloads a pre-compiled version of the application.
+   The browser loads executable code so it can render the application immediately, without waiting to compile the app first.
+
+* *Fewer asynchronous requests*
+   The compiler _inlines_ external HTML templates and CSS style sheets within the application JavaScript,
+   eliminating separate ajax requests for those source files.
+
+* *Smaller Angular framework download size*
+   There's no need to download the Angular compiler if the app is already compiled.
+   The compiler is roughly half of Angular itself, so omitting it dramatically reduces the application payload.
+
+* *Detect template errors earlier*
+   The AOT compiler detects and reports template binding errors during the build step
+   before users can see them.
+
+* *Better security*
+   AOT compiles HTML templates and components into JavaScript files long before they are served to the client.
+   With no templates to read and no risky client-side HTML or JavaScript evaluation,
+   there are fewer opportunities for injection attacks.
+
+{@a overview}
+
+## Choosing a compiler
+
+Angular offers two ways to compile your application:
+
+* **_Just-in-Time_ (JIT)**, which compiles your app in the browser at runtime. This was the default until Angular 8.
+* **_Ahead-of-Time_ (AOT)**, which compiles your app and libraries at build time. This is the default since Angular 9.
+
+When you run the [`ng build`](cli/build) (build only) or [`ng serve`](cli/serve) (build and serve locally) CLI commands, the type of compilation (JIT or AOT) depends on the value of the `aot` property in your build configuration specified in `angular.json`. By default, `aot` is set to `true` for new CLI apps.
+
+See the [CLI command reference](cli) and [Building and serving Angular apps](guide/build) for more information.
+
+## How AOT works
+
+The Angular AOT compiler extracts **metadata** to interpret the parts of the application that Angular is supposed to manage.
+You can specify the metadata explicitly in **decorators** such as `@Component()` and `@Input()`, or implicitly in the constructor declarations of the decorated classes.
+The metadata tells Angular how to construct instances of your application classes and interact with them at runtime.
+
+In the following example, the `@Component()` metadata object and the class constructor tell Angular how to create and display an instance of `TypicalComponent`.
+
+```typescript
+@Component({
+  selector: 'app-typical',
+  template: '<div>A typical component for {{data.name}}</div>'
+)}
+export class TypicalComponent {
+  @Input() data: TypicalData;
+  constructor(private someService: SomeService) { ... }
+}
+```
+
+The Angular compiler extracts the metadata _once_ and generates a _factory_ for `TypicalComponent`.
+When it needs to create a `TypicalComponent` instance, Angular calls the factory, which produces a new visual element, bound to a new instance of the component class with its injected dependency.
+
+### Compilation phases
+
+There are three phases of AOT compilation.
+* Phase 1 is *code analysis*.
+   In this phase, the TypeScript compiler and  *AOT collector* create a representation of the source. The collector does not attempt to interpret the metadata it collects. It represents the metadata as best it can and records errors when it detects a metadata syntax violation.
+
+* Phase 2 is *code generation*.
+    In this phase, the compiler's `StaticReflector` interprets the metadata collected in phase 1, performs additional validation of the metadata, and throws an error if it detects a metadata restriction violation.
+
+* Phase 3 is *template type checking*.
+   In this optional phase, the Angular *template compiler* uses the TypeScript compiler to validate the binding expressions in templates. You can enable this phase explicitly by setting the `fullTemplateTypeCheck` configuration option; see [Angular compiler options](guide/angular-compiler-options).
+
+
+### Metadata restrictions
+
+You write metadata in a _subset_ of TypeScript that must conform to the following general constraints:
+
+* Limit [expression syntax](#expression-syntax) to the supported subset of JavaScript.
+* Only reference exported symbols after [code folding](#code-folding).
+* Only call [functions supported](#supported-functions) by the compiler.
+* Decorated and data-bound class members must be public.
+
+For additional guidelines and instructions on preparing an application for AOT compilation, see [Angular: Writing AOT-friendly applications](https://medium.com/sparkles-blog/angular-writing-aot-friendly-applications-7b64c8afbe3f).
+
+<div class="alert is-helpful">
+
+Errors in AOT compilation commonly occur because of metadata that does not conform to the compiler's requirements (as described more fully below).
+For help in understanding and resolving these problems, see [AOT Metadata Errors](guide/aot-metadata-errors).
+
+</div>
+
+### Configuring AOT compilation
+
+You can provide options in the [TypeScript configuration file](guide/typescript-configuration) that controls the compilation process. See [Angular compiler options](guide/angular-compiler-options) for a complete list of available options.
+
+## Phase 1: Code analysis
+
+The TypeScript compiler does some of the analytic work of the first phase. It emits the `.d.ts` _type definition files_ with type information that the AOT compiler needs to generate application code.
+At the same time, the AOT **collector** analyzes the metadata recorded in the Angular decorators and outputs metadata information in **`.metadata.json`** files, one per `.d.ts` file.
+
+You can think of `.metadata.json` as a diagram of the overall structure of a decorator's metadata, represented as an [abstract syntax tree (AST)](https://en.wikipedia.org/wiki/Abstract_syntax_tree).

+<div class="alert is-helpful">

+
+{@a expression-syntax}
+### Expression syntax limitations
+
+The AOT collector only understands a subset of JavaScript.
+Define metadata objects with the following limited syntax:
+
+<style>
+  td, th {vertical-align: top}
+</style>
+
+<table>
+  <tr>
+    <th>Syntax</th>
+    <th>Example</th>

+    <td><code>Component</code></td>
+  </tr>
+   <tr>
+    <td>A template string</td>
+    <td><code>`pie is ${multiplier} times better than cake`</code></td>
+   <tr>
+    <td>Literal string</td>
+    <td><code>pi</code></td>
+  </tr>
+   <tr>
+    <td>Literal number</td>
+    <td><code>3.14153265</code></td>
+  </tr>
+   <tr>
+    <td>Literal boolean</td>
+    <td><code>true</code></td>
+  </tr>
+   <tr>
+    <td>Literal null</td>
+    <td><code>null</code></td>
+  </tr>
+   <tr>
+    <td>Supported prefix operator </td>
+    <td><code>!cake</code></td>
+  </tr>
+   <tr>
+    <td>Supported binary operator </td>
+    <td><code>a+b</code></td>
+  </tr>
+   <tr>
+    <td>Conditional operator</td>
+    <td><code>a ? b : c</code></td>
+  </tr>
+   <tr>
+    <td>Parentheses</td>
+    <td><code>(a+b)</code></td>
+  </tr>
+</table>
+
+
+If an expression uses unsupported syntax, the collector writes an error node to the `.metadata.json` file.
+The compiler later reports the error if it needs that piece of metadata to generate the application code.
+
+<div class="alert is-helpful">
+
+ If you want `ngc` to report syntax errors immediately rather than produce a `.metadata.json` file with errors, set the `strictMetadataEmit` option in the TypeScript configuration file.
+
+```
+  "angularCompilerOptions": {
+   ...
+   "strictMetadataEmit" : true
+ }
+ ```
+
+Angular libraries have this option to ensure that all Angular `.metadata.json` files are clean and it is a best practice to do the same when building your own libraries.
+
+</div>
+
+{@a function-expression}
+{@a arrow-functions}
+### No arrow functions
+
+The AOT compiler does not support [function expressions](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/function)
+and [arrow functions](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/Arrow_functions), also called _lambda_ functions.
+
+Consider the following component decorator:
+
+```typescript
+@Component({
+  ...
+  providers: [{provide: server, useFactory: () => new Server()}]
+})
+```
+
+The AOT collector does not support the arrow function, `() => new Server()`, in a metadata expression.
+It generates an error node in place of the function.
+When the compiler later interprets this node, it reports an error that invites you to turn the arrow function into an _exported function_.
+
+You can fix the error by converting to this:
+
+```typescript
+export function serverFactory() {
+  return new Server();
+}
+
+@Component({
+  ...
+  providers: [{provide: server, useFactory: serverFactory}]
+})
+```
+
+In version 5 and later, the compiler automatically performs this rewriting while emitting the `.js` file.
+
+{@a exported-symbols}
+{@a code-folding}
+### Code folding
+
+The compiler can only resolve references to **_exported_** symbols.
+The collector, however, can evaluate an expression during collection and record the result in the `.metadata.json`, rather than the original expression.
+This allows you to make limited use of non-exported symbols within expressions.
+
+For example, the collector can evaluate the expression `1 + 2 + 3 + 4` and replace it with the result, `10`.
+This process is called _folding_. An expression that can be reduced in this manner is _foldable_.
+
+{@a var-declaration}
+The collector can evaluate references to module-local `const` declarations and initialized `var` and `let` declarations, effectively removing them from the `.metadata.json` file.
+
+Consider the following component definition:
+
+```typescript
+const template = '<div>{{hero.name}}</div>';
+
+@Component({
+  selector: 'app-hero',
+  template: template
+})
+export class HeroComponent {
+  @Input() hero: Hero;
+}
+```
+
+The compiler could not refer to the `template` constant because it isn't exported.
+The collector, however, can fold the `template` constant into the metadata definition by in-lining its contents.
+The effect is the same as if you had written:
+
+```typescript
+@Component({
+  selector: 'app-hero',
+  template: '<div>{{hero.name}}</div>'
+})
+export class HeroComponent {
+  @Input() hero: Hero;
+}
+```
+
+There is no longer a reference to `template` and, therefore, nothing to trouble the compiler when it later interprets the _collector's_ output in `.metadata.json`.
+
+You can take this example a step further by including the `template` constant in another expression:
+
+```typescript
+const template = '<div>{{hero.name}}</div>';
+
+@Component({
+  selector: 'app-hero',
+  template: template + '<div>{{hero.title}}</div>'
+})
+export class HeroComponent {
+  @Input() hero: Hero;
+}
+```
+
+The collector reduces this expression to its equivalent _folded_ string:
+
+```
+'<div>{{hero.name}}</div><div>{{hero.title}}</div>'
+```
+
+#### Foldable syntax
+
+The following table describes which expressions the collector can and cannot fold:
+
+<style>
+  td, th {vertical-align: top}
+</style>
+
+<table>
+  <tr>
+    <th>Syntax</th>
+    <th>Foldable</th>
+  </tr>
+  <tr>
+    <td>Literal object </td>
+    <td>yes</td>
+  </tr>
+  <tr>
+    <td>Literal array  </td>
+    <td>yes</td>
+  </tr>
+  <tr>
+    <td>Spread in literal array</td>
+    <td>no</td>
+  </tr>
+   <tr>
+    <td>Calls</td>
+    <td>no</td>
+  </tr>
+   <tr>
+    <td>New</td>
+    <td>no</td>
+  </tr>
+   <tr>
+    <td>Property access</td>
+    <td>yes, if target is foldable</td>
+  </tr>
+   <tr>
+    <td>Array index</td>
+    <td> yes, if target and index are foldable</td>
+  </tr>
+   <tr>
+    <td>Identity reference</td>
+    <td>yes, if it is a reference to a local</td>
+  </tr>
+   <tr>
+    <td>A template with no substitutions</td>
+    <td>yes</td>
+  </tr>
+   <tr>
+    <td>A template with substitutions</td>
+    <td>yes, if the substitutions are foldable</td>
+  </tr>
+   <tr>
+    <td>Literal string</td>
+    <td>yes</td>
+  </tr>
+   <tr>
+    <td>Literal number</td>
+    <td>yes</td>
+  </tr>
+   <tr>
+    <td>Literal boolean</td>
+    <td>yes</td>
+  </tr>
+   <tr>
+    <td>Literal null</td>
+    <td>yes</td>
+  </tr>
+   <tr>
+    <td>Supported prefix operator </td>
+    <td>yes, if operand is foldable</td>
+  </tr>
+   <tr>
+    <td>Supported binary operator </td>
+    <td>yes, if both left and right are foldable</td>
+  </tr>
+   <tr>
+    <td>Conditional operator</td>
+    <td>yes, if condition is foldable </td>
+  </tr>
+   <tr>
+    <td>Parentheses</td>
+    <td>yes, if the expression is foldable</td>
+  </tr>
+</table>
+
+
+If an expression is not foldable, the collector writes it to `.metadata.json` as an [AST](https://en.wikipedia.org/wiki/Abstract_syntax_tree) for the compiler to resolve.
+
+
+## Phase 2: code generation
+
+The collector makes no attempt to understand the metadata that it collects and outputs to `.metadata.json`.
+It represents the metadata as best it can and records errors when it detects a metadata syntax violation.
+It's the compiler's job to interpret the `.metadata.json` in the code generation phase.
+
+The compiler understands all syntax forms that the collector supports, but it may reject _syntactically_ correct metadata if the _semantics_ violate compiler rules.
+
+### Public symbols
+
+The compiler can only reference _exported symbols_.
+
+* Decorated component class members must be public. You cannot make an `@Input()` property private or protected.
+* Data bound properties must also be public.
+
+```typescript
+// BAD CODE - title is private
+@Component({
+  selector: 'app-root',
+  template: '<h1>{{title}}</h1>'
+})
+export class AppComponent {
+  private title = 'My App'; // Bad
+}
+```
+
+{@a supported-functions}
+
+### Supported classes and functions
+
+The collector can represent a function call or object creation with `new` as long as the syntax is valid.
+The compiler, however, can later refuse to generate a call to a _particular_ function or creation of a _particular_ object.
+
+The compiler can only create instances of certain classes, supports only core decorators, and only supports calls to macros (functions or static methods) that return expressions.
+* New instances
+
+   The compiler only allows metadata that create instances of the class `InjectionToken` from `@angular/core`.
+
+* Supported decorators
+
+   The compiler only supports metadata for the [Angular decorators in the `@angular/core` module](api/core#decorators).
+
+* Function calls
+
+   Factory functions must be exported, named functions.
+   The AOT compiler does not support lambda expressions ("arrow functions") for factory functions.
+
+{@a function-calls}
+### Functions and static method calls
+
+The collector accepts any function or static method that contains a single `return` statement.
+The compiler, however, only supports macros in the form of functions or static methods that return an *expression*.
+
+For example, consider the following function:
+
+```typescript
+export function wrapInArray<T>(value: T): T[] {
+  return [value];
+}
+```
+
+You can call the `wrapInArray` in a metadata definition because it returns the value of an expression that conforms to the compiler's restrictive JavaScript subset.
+
+You might use  `wrapInArray()` like this:
+
+```typescript
+@NgModule({
+  declarations: wrapInArray(TypicalComponent)
+})
+export class TypicalModule {}
+```
+
+The compiler treats this usage as if you had written:
+
+```typescript
+@NgModule({
+  declarations: [TypicalComponent]
+})
+export class TypicalModule {}
+```
+The Angular [`RouterModule`](api/router/RouterModule) exports two macro static methods, `forRoot` and `forChild`, to help declare root and child routes.
+Review the [source code](https://github.com/angular/angular/blob/master/packages/router/src/router_module.ts#L139 "RouterModule.forRoot source code")
+for these methods to see how macros can simplify configuration of complex [NgModules](guide/ngmodules).
+
+{@a metadata-rewriting}
+
+### Metadata rewriting
+
+The compiler treats object literals containing the fields `useClass`, `useValue`, `useFactory`, and `data` specially, converting the expression initializing one of these fields into an exported variable that replaces the expression.
+This process of rewriting these expressions removes all the restrictions on what can be in them because
+the compiler doesn't need to know the expression's value&mdash;it just needs to be able to generate a reference to the value.
+
+You might write something like:
+
+```typescript
+class TypicalServer {
+
+}
+
+@NgModule({
+  providers: [{provide: SERVER, useFactory: () => TypicalServer}]
+})
+export class TypicalModule {}
+```
+
+Without rewriting, this would be invalid because lambdas are not supported and `TypicalServer` is not exported.
+To allow this, the compiler automatically rewrites this to something like:
+
+```typescript
+class TypicalServer {
+
+}
+
+export const ɵ0 = () => new TypicalServer();
+
+@NgModule({
+  providers: [{provide: SERVER, useFactory: ɵ0}]
+})
+export class TypicalModule {}
+```
+
+This allows the compiler to generate a reference to `ɵ0` in the factory without having to know what the value of `ɵ0` contains.
+
+The compiler does the rewriting during the emit of the `.js` file.
+It does not, however, rewrite the `.d.ts` file, so TypeScript doesn't recognize it as being an export. and it does not interfere with the ES module's exported API.
+
+
+{@a binding-expression-validation}
+
+## Phase 3: Template type checking
+
+One of the Angular compiler's most helpful features is the ability to type-check expressions within templates, and catch any errors before they cause crashes at runtime.
+In the template type-checking phase, the Angular template compiler uses the TypeScript compiler to validate the binding expressions in templates.
+
+Enable this phase explicitly by adding the compiler option `"fullTemplateTypeCheck"` in the `"angularCompilerOptions"` of the project's TypeScript configuration file
+(see [Angular Compiler Options](guide/angular-compiler-options)).
+
+<div class="alert is-helpful">
+
+In [Angular Ivy](guide/ivy), the template type checker has been completely rewritten to be more capable as well as stricter, meaning it can catch a variety of new errors that the previous type checker would not detect.
+
+As a result, templates that previously compiled under View Engine can fail type checking under Ivy. This can happen because Ivy's stricter checking catches genuine errors, or because application code is not typed correctly, or because the application uses libraries in which typings are inaccurate or not specific enough.
+
+This stricter type checking is not enabled by default in version 9, but can be enabled by setting the `strictTemplates` configuration option.
+We do expect to make strict type checking the default in the future.
+
+For more information about type-checking options, and about improvements to template type checking in version 9 and above, see [Template type checking](guide/template-typecheck).
+
+</div>
+
+Template validation produces error messages when a type error is detected in a template binding
+expression, similar to how type errors are reported by the TypeScript compiler against code in a `.ts`
+file.
+
+For example, consider the following component:
+
+```typescript
+  @Component({
+    selector: 'my-component',
+    template: '{{person.addresss.street}}'
+  })
+  class MyComponent {
+    person?: Person;
+  }
+```
+
+This produces the following error:
+
+```
+  my.component.ts.MyComponent.html(1,1): : Property 'addresss' does not exist on type 'Person'. Did you mean 'address'?
+ ```
+
+The file name reported in the error message, `my.component.ts.MyComponent.html`, is a synthetic file
+generated by the template compiler that holds contents of the `MyComponent` class template.
+The compiler never writes this file to disk.
+The line and column numbers are relative to the template string in the `@Component` annotation of the class, `MyComponent` in this case.
+If a component uses `templateUrl` instead of `template`, the errors are reported in the HTML file referenced by the `templateUrl` instead of a synthetic file.
+
+The error location is the beginning of the text node that contains the interpolation expression with the error.
+If the error is in an attribute binding such as `[value]="person.address.street"`, the error
+location is the location of the attribute that contains the error.
+
+The validation uses the TypeScript type checker and the options supplied to the TypeScript compiler to control how detailed the type validation is.
+For example, if the `strictTypeChecks` is specified, the error
+```my.component.ts.MyComponent.html(1,1): : Object is possibly 'undefined'```
+is reported as well as the above error message.
+
+### Type narrowing
+
+The expression used in an `ngIf` directive is used to narrow type unions in the Angular
+template compiler, the same way the `if` expression does in TypeScript.
+For example, to avoid `Object is possibly 'undefined'` error in the template above, modify it to only emit the interpolation if the value of `person` is initialized as shown below:
+
+```typescript
+  @Component({
+    selector: 'my-component',
+    template: '<span *ngIf="person"> {{person.addresss.street}} </span>'
+  })
+  class MyComponent {
+    person?: Person;
+  }
+```
+
+Using `*ngIf` allows the TypeScript compiler to infer that the `person` used in the binding expression will never be `undefined`.
+
+For more information about input type narrowing, see [Input setter coercion](guide/template-typecheck#input-setter-coercion) and [Improving template type checking for custom directives](guide/structural-directives#directive-type-checks).
+
+### Non-null type assertion operator
+
+Use the [non-null type assertion operator](guide/template-expression-operators#non-null-assertion-operator) to suppress the `Object is possibly 'undefined'` error when it is inconvenient to use `*ngIf` or when some constraint in the component ensures that the expression is always non-null when the binding expression is interpolated.
+
+In the following example, the `person` and `address` properties are always set together, implying that `address` is always non-null if `person` is non-null.
+There is no convenient way to describe this constraint to TypeScript and the template compiler, but the error is suppressed in the example by using `address!.street`.
+
+```typescript
+  @Component({
+    selector: 'my-component',
+    template: '<span *ngIf="person"> {{person.name}} lives on {{address!.street}} </span>'
+  })
+  class MyComponent {
+    person?: Person;
+    address?: Address;
+
+    setData(person: Person, address: Address) {
+      this.person = person;
+      this.address = address;
+    }
+  }
+```
+
+The non-null assertion operator should be used sparingly as refactoring of the component might break this constraint.
+
+In this example it is recommended to include the checking of `address` in the `*ngIf` as shown below:
+
+```typescript
+  @Component({
+    selector: 'my-component',
+    template: '<span *ngIf="person && address"> {{person.name}} lives on {{address.street}} </span>'
+  })
+  class MyComponent {
+    person?: Person;
+    address?: Address;
+
+    setData(person: Person, address: Address) {
+      this.person = person;
+      this.address = address;
+    }
+  }
+```

 {@a why-aot}
 
-Here are some reasons you might want to use AOT.
+Aquí algunas razones por las qué podrías querer usar AOT.
 
-* *Faster rendering*
+* *Renderizado más rápido*
-   With AOT, the browser downloads a pre-compiled version of the application.
+   Con AOT, el navegador descarga una versión pre compilada de una aplicación.
-   The browser loads executable code so it can render the application immediately, without waiting to compile the app first.
+   El navegador carga el código ejecutable para que pueda renderizar la aplicación inmediatamente, sin esperar a compilar la aplicación primero.
 
-* *Fewer asynchronous requests*
+* *Menos solicitudes asincrónicas*
-   The compiler _inlines_ external HTML templates and CSS style sheets within the application JavaScript,
+   El compilador _inserta_ plantillas HTML y hojas de estilo CSS externas dentro de la aplicación JavaScript, eliminando solicitudes ajax separadas para esos archivos fuente.
-   eliminating separate ajax requests for those source files.
 
-* *Smaller Angular framework download size*
+* *Angular pesa menos*
-   There's no need to download the Angular compiler if the app is already compiled.
+   No existe necesidad de incluir el compilador de Angular si la aplicación ya esta compilada.
-   The compiler is roughly half of Angular itself, so omitting it dramatically reduces the application payload.
+   El compilador es aproximadamente la mitad de Angular en si mismo, así que omitíendolo se reduce drásticamente el peso de la aplicación.
 
-* *Detect template errors earlier*
+* *Detecte errores en platillas antes*
-   The AOT compiler detects and reports template binding errors during the build step
+   El compilador AOT detecta y reporta errores de enlace de datos en plantillas durante el paso de construcción antes que los usuarios puedan verlos.
-   before users can see them.
 
-* *Better security*
+* *Mejor seguridad*
-   AOT compiles HTML templates and components into JavaScript files long before they are served to the client.
+   AOT compila las plantillas HTML y componentes en archivos JavaScript mucho antes de que se sirvan a el cliente.
-   With no templates to read and no risky client-side HTML or JavaScript evaluation,
+   Sin plantillas para leer y sin evaluaciones de JavaScript o HTML del lado del cliente riesgosas, existen pocas oportunidades para ataques de inyección.
-   there are fewer opportunities for injection attacks.
 
 {@a overview}
 
-## Choosing a compiler
+## Eligiendo un compilador.
 
-Angular offers two ways to compile your application:
+Angular ofrece dos formas para compilar tu aplicación:
 
-* **_Just-in-Time_ (JIT)**, which compiles your app in the browser at runtime. This was the default until Angular 8.
+* **_Just-in-Time_ (JIT)**, cuando compila tu aplicación en el navegador en tiempo de ejecución. Este fué el modo de compilación por defecto hasta Angular 8.
-* **_Ahead-of-Time_ (AOT)**, which compiles your app and libraries at build time. This is the default since Angular 9.
+* **_Ahead-of-Time_ (AOT)**, cuando compila tu aplicación y librerías en el tiempo de construcción. Este es el modo de compilación por defecto desde Angular 9.
 
-When you run the [`ng build`](cli/build) (build only) or [`ng serve`](cli/serve) (build and serve locally) CLI commands, the type of compilation (JIT or AOT) depends on the value of the `aot` property in your build configuration specified in `angular.json`. By default, `aot` is set to `true` for new CLI apps.
+Cuando ejecutas los comandos del CLI [`ng build`](cli/build) (solo construcción) o [`ng serve`](cli/serve) (construye y sirve localmente), el tipo de compilación (JIT o AOT) depende del valor de la propiedad `aot` en tu configuración de construcción especificada en el archivo `angular.json`. Por defecto, `aot` esta establecido en `true` para nuevas aplicaciones.
 
-See the [CLI command reference](cli) and [Building and serving Angular apps](guide/build) for more information.
+Mira la [referencia de comandos del CLI](cli) y [Construyendo y sirviendo Angular apps](guide/build) para más información.
 
-## How AOT works
+## Como funciona AOT
 
-The Angular AOT compiler extracts **metadata** to interpret the parts of the application that Angular is supposed to manage.
+El compilador de Angular AOT extrae **metadatos** para interpretar las partes de la aplicación que se supone que Angular maneja.
-You can specify the metadata explicitly in **decorators** such as `@Component()` and `@Input()`, or implicitly in the constructor declarations of the decorated classes.
+Puedes especificar los metadatos explícitamente en **decoradores** como `@Component()` y `@Input()`, o implícitamente en las declaraciones del constructor de las clases decoradas.
-The metadata tells Angular how to construct instances of your application classes and interact with them at runtime.
+Los metadatos le dicen a Angular como construir instancias de clases e interactuar con ellas en tiempo de ejecución.
 
-In the following example, the `@Component()` metadata object and the class constructor tell Angular how to create and display an instance of `TypicalComponent`.
+En el siguiente ejemplo, los metadatos de `@Component()` y el constructor le dicen a Angular como crear y mostrar una instancia de `TypicalComponent`.
 
 ```typescript
 @Component({
   selector: 'app-typical',
   template: '<div>A typical component for {{data.name}}</div>'
-})
+)}
 export class TypicalComponent {
   @Input() data: TypicalData;
   constructor(private someService: SomeService) { ... }
 }
 ```
 
-The Angular compiler extracts the metadata _once_ and generates a _factory_ for `TypicalComponent`.
+El compilador de Angular extrae los metadatos _una_ vez y genera una _fabrica_ para `TypicalComponent`.
-When it needs to create a `TypicalComponent` instance, Angular calls the factory, which produces a new visual element, bound to a new instance of the component class with its injected dependency.
+Cuando este necesita crear una instancia de `TypicalComponent`, Angular llama a la fabrica, el cuál produce un nuevo elemento visual, vinculado a una nueva instancia la clase del componente con su dependencia inyectada.
 
-### Compilation phases
+### Fases de compilación
 
-There are three phases of AOT compilation.
+Existen tres fases de compilación en AOT.
-* Phase 1 is *code analysis*.
-   In this phase, the TypeScript compiler and  *AOT collector* create a representation of the source. The collector does not attempt to interpret the metadata it collects. It represents the metadata as best it can and records errors when it detects a metadata syntax violation.
 
-* Phase 2 is *code generation*.
+* Fase 1: *análisis de código*
-    In this phase, the compiler's `StaticReflector` interprets the metadata collected in phase 1, performs additional validation of the metadata, and throws an error if it detects a metadata restriction violation.
+   En esta fase, el compilador de TypeScript y el *recolector AOT* crea una representación de la fuente. El recolector no intenta interpretar los metadatos recopilados. Estos representan los metadatos lo mejor que pueden y registra errores cuando este detecta un violación de sintaxis en los metadatos.
 
-* Phase 3 is *template type checking*.
+* Fase 2: *generación de código*
-   In this optional phase, the Angular *template compiler* uses the TypeScript compiler to validate the binding expressions in templates. You can enable this phase explicitly by setting the `fullTemplateTypeCheck` configuration option; see [Angular compiler options](guide/angular-compiler-options).
+   En esta fase, el `StaticReflector` del compilador interpreta los metadatos recolectados en la fase 1, realiza validaciones adicionales de los metadatos y lanza un error si este detecta una violación de la restricción de metadatos.
+
+* Fase 3: *verificación de tipos en plantillas*
+   Esta fase es opcional, el *compilador de plantillas* de Angular usa el compilador de Typescript para validar las expresiones de enlaces de datos en las plantillas. Puedes habilitar esta fase explícitamente configurando la opción `fullTemplateTypeCheck`; revisa [Opciones del Compilador Angular](guide/angular-compiler-options).
 
 
-### Metadata restrictions
+### Restricciones de los metadatos
 
-You write metadata in a _subset_ of TypeScript that must conform to the following general constraints:
+Escribe metadatos en un _subconjunto_ de TypeScript que debe cumplir las siguientes restricciones generales:
 
-* Limit [expression syntax](#expression-syntax) to the supported subset of JavaScript.
+* Limita la [sintaxis de expresiones](#expression-syntax) al subconjunto soportado de JavaScript.
-* Only reference exported symbols after [code folding](#code-folding).
+* Solo haz referencia a los símbolos exportados después del [plegado de código](#code-folding).
-* Only call [functions supported](#supported-functions) by the compiler.
+* Solo llame [funciones compátibles](#supported-functions) por el compilador.
-* Decorated and data-bound class members must be public.
+* Miembros de clase decorados y con enlaces de datos deben ser públicos.

+Al mismo tiempo, el **recolector** AOT analiza los metadatos registrados en los decoradores de Angular y genera información de metadatos en archivos **`.metadata.json`**, uno por archivo `.d.ts`.

+# Introduction to modules
+
+Angular apps are modular and Angular has its own modularity system called *NgModules*.
+NgModules are containers for a cohesive block of code dedicated to an application domain, a workflow, or a closely related set of capabilities. They can contain components, service providers, and other code files whose scope is defined by the containing NgModule. They can import functionality that is exported from other NgModules, and export selected functionality for use by other NgModules.
+
+Every Angular app has at least one NgModule class, [the *root module*](guide/bootstrapping), which is conventionally named `AppModule` and resides in a file named `app.module.ts`. You launch your app by *bootstrapping* the root NgModule.
+
+While a small application might have only one NgModule, most apps have many more *feature modules*. The *root* NgModule for an app is so named because it can include child NgModules in a hierarchy of any depth.
+
+## NgModule metadata
+
+An NgModule is defined by a class decorated with `@NgModule()`. The `@NgModule()` decorator is a function that takes a single metadata object, whose properties describe the module. The most important properties are as follows.
+
+* `declarations`: The [components](guide/architecture-components), *directives*, and *pipes* that belong to this NgModule.
+
+* `exports`: The subset of declarations that should be visible and usable in the *component templates* of other NgModules.
+
+* `imports`: Other modules whose exported classes are needed by component templates declared in *this* NgModule.
+
+* `providers`: Creators of [services](guide/architecture-services) that this NgModule contributes to the global collection of services; they become accessible in all parts of the app. (You can also specify providers at the component level, which is often preferred.)
+
+* `bootstrap`: The main application view, called the *root component*, which hosts all other app views. Only the *root NgModule* should set the `bootstrap` property.
+
+Here's a simple root NgModule definition.
+
+<code-example path="architecture/src/app/mini-app.ts" region="module" header="src/app/app.module.ts"></code-example>
+
+<div class="alert is-helpful">
+
+  `AppComponent` is included in the `exports` list here for illustration; it isn't actually necessary in this example. A root NgModule has no reason to *export* anything because other modules don't need to *import* the root NgModule.
+
+</div>
+
+## NgModules and components
+
+NgModules provide a *compilation context* for their components. A root NgModule always has a root component that is created during bootstrap, but any NgModule can include any number of additional components, which can be loaded through the router or created through the template. The components that belong to an NgModule share a compilation context.
+
+<div class="lightbox">
+  <img src="generated/images/guide/architecture/compilation-context.png" alt="Component compilation context" class="left">
+</div>
+
+<br class="clear">
+
+A component and its template together define a *view*. A component can contain a *view hierarchy*, which allows you to define arbitrarily complex areas of the screen that can be created, modified, and destroyed as a unit. A view hierarchy can mix views defined in components that belong to different NgModules. This is often the case, especially for UI libraries.
+
+<div class="lightbox">
+  <img src="generated/images/guide/architecture/view-hierarchy.png" alt="View hierarchy" class="left">
+</div>
+
+<br class="clear">
+
+When you create a component, it's associated directly with a single view, called the *host view*. The host view can be the root of a view hierarchy, which can contain *embedded views*, which are in turn the host views of other components. Those components can be in the same NgModule, or can be imported from other NgModules. Views in the tree can be nested to any depth.
+
+<div class="alert is-helpful">
+
+**Note:** The hierarchical structure of views is a key factor in the way Angular detects and responds to changes in the DOM and app data.
+
+</div>
+
+## NgModules and JavaScript modules
+
+The NgModule system is different from and unrelated to the JavaScript (ES2015) module system for managing collections of JavaScript objects. These are *complementary* module systems that you can use together to write your apps.
+
+In JavaScript each *file* is a module and all objects defined in the file belong to that module.
+The module declares some objects to be public by marking them with the `export` key word.
+Other JavaScript modules use *import statements* to access public objects from other modules.
+
+<code-example path="architecture/src/app/app.module.ts" region="imports"></code-example>

+
+<div class="alert is-helpful">
+  <a href="http://exploringjs.com/es6/ch_modules.html">Learn more about the JavaScript module system on the web.</a>
+</div>
+
+## Angular libraries
+
+<img src="generated/images/guide/architecture/library-module.png" alt="Component" class="left">
+
+Angular loads as a collection of JavaScript modules. You can think of them as library modules. Each Angular library name begins with the `@angular` prefix. Install them with the node package manager `npm` and import parts of them with JavaScript `import` statements.
+
+<br class="clear">
+
+For example, import Angular's `Component` decorator from the `@angular/core` library like this.
+
+<code-example path="architecture/src/app/app.component.ts" region="import"></code-example>
+
+You also import NgModules from Angular *libraries* using JavaScript import statements.
+For example, the following code imports the `BrowserModule` NgModule from the `platform-browser` library.
+
+<code-example path="architecture/src/app/mini-app.ts" region="import-browser-module"></code-example>
+
+In the example of the simple root module above, the application module needs material from within
+`BrowserModule`. To access that material, add it to the `@NgModule` metadata `imports` like this.
+
+<code-example path="architecture/src/app/mini-app.ts" region="ngmodule-imports"></code-example>
+
+In this way you're using the Angular and JavaScript module systems *together*. Although it's easy to confuse the two systems, which share the common vocabulary of "imports" and "exports", you will become familiar with the different contexts in which they are used.
