This allows Angular to error on unknown properties,
allowing applications that don’t use custom elements
to get better error reporting.
Part of #10043
BREAKING CHANGE:
- By default, Angular will error during parsing
on unknown properties,
even if they are on elements with a `-` in their name
(aka custom elements). If you application is using
custom elements, fill the new parameter `@NgModule.schemas`
with the value `[CUSTOM_ELEMENTS_SCHEMA]`.
E.g. for bootstrap:
```
bootstrap(MyComponent, {schemas: [CUSTOM_ELEMENTS_SCHEMA]});
```
This introduces the `BrowserModule` to be used for long form
bootstrap and offline compile bootstrap:
```
@AppModule({
modules: [BrowserModule],
precompile: [MainComponent],
providers: […], // additional providers
directives: […], // additional platform directives
pipes: […] // additional platform pipes
})
class MyModule {
constructor(appRef: ApplicationRef) {
appRef.bootstrap(MainComponent);
}
}
// offline compile
import {bootstrapModuleFactory} from ‘@angular/platform-browser’;
bootstrapModuleFactory(MyModuleNgFactory);
// runtime compile long form
import {bootstrapModule} from ‘@angular/platform-browser-dynamic’;
bootstrapModule(MyModule);
```
The short form, `bootstrap(...)`, can now creates a module on the fly,
given `directives`, `pipes, `providers`, `precompile` and `modules`
properties.
Related changes:
- make `SanitizationService`, `SecurityContext` public in `@angular/core` so that the offline compiler can resolve the token
- move `AnimationDriver` to `platform-browser` and make it
public so that the offline compiler can resolve the token
BREAKING CHANGES:
- short form bootstrap does no longer allow
to inject compiler internals (i.e. everything
from `@angular/compiler). Inject `Compiler` instead.
To provide custom providers for the compiler,
create a custom compiler via `browserCompiler({providers: [...]})`
and pass that into the `bootstrap` method.
This addresses several oversights in assigning security contexts to DOM schema
elements found by our security reviewers (thanks!).
This also adds some more precise unit tests for the interaction between
(Dom)ElementSchemaRegistry and the TemplateParser, and extracts the security
specific parts into dom_security_schema.ts.
Comparison of (potentially) dangerous property names is done case insensitive,
to avoid issues like formAction vs formaction.
Part of issue #8511.
Summary:
This adds basic security hooks to Angular 2.
* `SecurityContext` is a private API between core, compiler, and
platform-browser. `SecurityContext` communicates what context a value is used
in across template parser, compiler, and sanitization at runtime.
* `SanitizationService` is the bare bones interface to sanitize values for a
particular context.
* `SchemaElementRegistry.securityContext(tagName, attributeOrPropertyName)`
determines the security context for an attribute or property (it turns out
attributes and properties match for the purposes of sanitization).
Based on these hooks:
* `DomSchemaElementRegistry` decides what sanitization applies in a particular
context.
* `DomSanitizationService` implements `SanitizationService` and adds *Safe
Value*s, i.e. the ability to mark a value as safe and not requiring further
sanitization.
* `url_sanitizer` and `style_sanitizer` sanitize URLs and Styles, respectively
(surprise!).
`DomSanitizationService` is the default implementation bound for browser
applications, in the three contexts (browser rendering, web worker rendering,
server side rendering).
BREAKING CHANGES:
*** SECURITY WARNING ***
Angular 2 Release Candidates do not implement proper contextual escaping yet.
Make sure to correctly escape all values that go into the DOM.
