We have a number of observables that have `catch` handlers to recover
from errors without causing the stream to close, and breaking the app.
We also have some `try ... catch` blocks for synchronous code for a
similar reason.
In these cases we conventionally then call `logger.error` in the catch
handler. We are interested in these errors so we are going to capture them
by reporting them to Google Analytics via the new `ReportingErrorHandler`.
PR Close#22011
This is a basic implementation of error logging using the limited
facilities provided by Google Analytics.
Errors within the Angular app itself will be handled by a new
`ReportingErrorHandler` service, which overrides and extends the
built-in `ErrorHandler`.
Further, errors outside the app, which arrive at `window.onerror`
will also be reported to Google Analytics.

During the initial load of the page (probably until the icon styles are
loaded and/or applied), the `.header-link` element is wider, pushing the
heading text slightly to the right (for a brief moment).
This commit prevents this slight shift by explicitly setting the width
for the `.header-link` element.
PR Close#21695
For the initial rendering, where there is no transition from a previous
visual state to a new one, animations make little sense. The page should
load with as few reflows as possible.
Similarly, while we typically want to defer updating the SideNav state
(e.g. opened/closed) until the "leaving" document is animated out of the
page, on the initial rendering (where there is no "leaving" document)
this leads to the SideNav flashing (from closed to open).
These worked as expected before, but several parts (mostly related to
documents with a SideNav) have been accidentally broken in recent
commits (e.g. when upgraded to latest material, or enabled animations
for DocViewer transitions, etc.).
This commit restores the previous behavior by ensuring that (on the
initial rendering) the SideNav state is updated as soon as possible and
that there will be no animations when:
1. The hamburger button appears.
2. The SideNav is opened.
3. The main section's width is adjusted to make room for the SideNav.

Previously, the mocked `HttpClient` was synchronous in tests (despite
the actual `HttpClient` being asynchronous). Although we use observables
(which generally make the implementation sync/async-agnostic), the fact
that we have no control over when Angular updates/checks views and calls
lifecycle hooks resulted in different behavior (and errors) in tests
(with sync `HttpClient`) vs actual app (with async `HttpClient`).
This commit ensures that the behavior (and errors) are consistent
between the tests and the actual app by making the mocked `HttpClient`
asynchronous.

Navigating to a document while trying to expand or collapse a sub-menu
is undesirable and confusing. All sub-menu toggles should have no other
effect than expanding/collapsing the corresponding sub-menu.

Name of selector in ForbiddenName example is not consistent with Validator class nor Html selector example. Added the selector name 'appForbiddenName' as an alias name for the input of the Validator class, and updated the view accordingly.
Fixes: #20206
PR Close#20464
Previously searching for `compose` did not include `Validators`
in the search results because we were not including all the
`static` members of API docs in the index.

These tags are removed when the doc is ready and valid, but this will
allow us to block indexing in the case that the Angular app fails to
bootstrap or load the document for some non-404 reason.
This should get around the problem with hardcoded tags. See

This will prevent the confusing errors for first time users who
try to generate the docs with `yarn docs` and are told there are
dangling links.
Closes#21944
PR Close#21970
This has two benefits:
* it prepares the way for the API docs update, which need parameter docs
* it doesn't incorrectly report dangling links for non-latin anchors
Closes#21306
PR Close#21802
Running `yarn start` (which watches the `src/` directory) and
`yarn docs-watch` (which cleans up files in `src/generated/api/`) often
results in `ENOTEMPTY` errors.
This commit solves it by ensuring that `yarn docs` has been completed
before running `yarn start`.

Since we specify `bottom: 0`, specifying the height is unnecessary and
leads to wrong height (unless updated) on narrow screens where the
topbar height is decreased.
Partly addresses #21520.

Also, remove `plnkr.json` for `service-worker-getting-started` guide,
since it is not used and ServiceWorker cannot work correctly in
plnkr/stackblitz anyway (e.g. no build step to re-compute hashes).
A zipper might be useful and can be added in a subsequent PR, but it is
currently broken (e.g. no dependency on `@angular/service-worker`).

The `<meta name="robots" content="noindex">` tag is used
to indicate to search engine crawlers that they should not index
the current page. This is set dynamically by the the document
viewer component to ensure that 404 and other erroring pages
are not added to the search index.
This relies upon the idea that the crawling bot will run the JS
and wait to see if this meta tag has been added or not.
Since we believe that the `googebot` will do this, we also
pre-emptively add a hard-coded noindex tag specifically for
this bot, so that if anything else fails in bootstrapping the app,
the failed page will not be added to the index.
