In 305d05545a, we accidentally stopped
instantiating the `SwUpdatesService` service, which meant that we were
no longer subscribing to ServiceWorker update events and proactively
checking for updates. We would still gets updates, because the
ServiceWorker automatically checks on each navigation request and when a
new ServiceWorker instance is created, but we would not proactively
fetch updates and also miss `unrecoverable` errors.
This commit fixes this by exposing an `enable()` method from
`SwUpdatesService`, which has to be explicitly called for the service to
be enabled, and ensures that the method is called when `AppComponent` is
initialized.
The commit also gets rid of the `SwUpdatesModule` (whose only purpose
was to provide `SwUpdatesService`) in favor of using `providedIn`.

Previously, we used to prepend version info to error messages by
updating their `message` property and their `stack` property. However,
due to the fact that on some browsers `error.stack` is lazily computed
based on `error.message` the first time the `stack` property is
accessed, this resulted in prepending the version info twice.
This commit ensures that the version info is only prepended to
`error.stack` once to avoid unnecessary repetition in error messages.

The way the Sass rule was defined previously resulted in invalid CSS of
the form:
```css
table > thead > { ... }
```
This, in turn, resulted in a build-time warning:
```
Warning: > styles.9a5a35b070498c08.css:3079:14: warning: Unexpected "{"

```
This commit fixes the affected rule (mostly to avoid the warning,
because this change doesn't seem to have any visual difference). It also
fixes other rules that were currently not affected (because they only
had nested rules and no direct styles), but were susceptible to being
affected in the future.

PR Close#43586
Previously, anchor links that were supposed to point to fragments inside
the current page (e.g. `href="#something"`) would end up navigating to
the homepage (`/`). This was due to them being resolved relative to the

It seems that at some point (potentially with the switch to Webpack 5)
Webpack started using the full chunk name (instead of just a numeric

migrate aio to eslint as tslint has been deprecated, the migration is restricted to the aio app and
its e2e tests and does not include the other tools, for such reason both tslint and codelyzer have not
been removed (to be done in a next PR)
some minor tweaks needed to be applied to the code so that it would adhere to the new ESLinting behaviour
most TSLint rules have been substituted with their ESLint equivalent, with some exceptions:
* [whitespace] does not have an ESLint equivalent (suggested to be handled by prettier)
* [import-spacing] does not have an ESLint equivalent (suggested to be handled by prettier)
* [ban] replaced with [no-restricted-syntax] as there is no (official/included) ESLint equivalent
some rules have minor different behaviours compared to their TSLint counterparts:
* @typescript-eslint/naming-convention:
- typescript-eslint does not enforce uppercase for const only.
* @typescript-eslint/no-unused-expressions:
- The TSLint optional config "allow-new" is the default ESLint behavior and will no longer be ignored.
* arrow-body-style:
- ESLint will throw an error if the function body is multiline yet has a one-line return on it.
* eqeqeq:
- Option "smart" allows for comparing two literal values, evaluating the value of typeof and null comparisons.
* no-console:
- Custom console methods, if they exist, will no longer be allowed.
* no-invalid-this:
- Functions in methods will no longer be ignored.
* no-underscore-dangle:
- Leading and trailing underscores (_) on identifiers will now be ignored.
* prefer-arrow/prefer-arrow-functions:
- ESLint does not support allowing standalone function declarations.
- ESLint does not support allowing named functions defined with the function keyword.
* space-before-function-paren:
- Option "constructor" is not supported by ESLint.
- Option "method" is not supported by ESLint.
additional notes:
* the current typescript version used by the aio app is 4.3.5, which is not supported by typescript-eslint (the supported
versions are >=3.3.1 and <4.3.0). this causes a warning message to appear during linting, this issue should
likely/hopefully disappear in the future as typescript-eslint catches up
* The new "no-console" rule is not completely equivalent to what we had prior the migration, this is because TSLint's "no-console"
rule let you specify the methods you did not want to allow, whilst ESLint's "no-console" lets you specify the methods that you do
want to allow, so and in order not to have a very long list of methods in the ESLint rule it's been decided for the time being
to simply only allow the "log", "warn" and "error" methods
* 4 dependencies have been added as they have been considered necessary (see: https://github.com/angular/angular/pull/42820#discussion_r669978232)
extra:
* the migration has been performed by following: https://github.com/angular-eslint/angular-eslint#migrating-an-angular-cli-project-from-codelyzer-and-tslin

Previously, if there was more content than what would horizontally fit
in the main content area, it would overflow to the right and overlap
with the Table of Contents (ToC).
This was accidentally introduced in #42787.

Error-handling in AIO happens mainly in two places:
1. For errors happening inside the app we have a custom `ErrorHandler`
implementation, `ReportingErrorHandler`. `ReportingErrorHandler`
passes errors to the default `ErrorHandler` (for them to be logged to
the console) and also forwards them to `window.onerror()`.
2. Errors happening outside the app and errors forwarded by
`ReportingErrorHandler` are handled by `window.onerror()`, which in
turn reports them to Google analytics.
Previously, we were making some assumptions (which turned out to be
incorrect based on the info captured in Google analytics - see #28106):
- `ReportingErrorHandler` assumed that the errors passed to its
`handleError()` method would be either strings or `Error` instances.
_Apparently, other values (such as `null` or `undefined`) may also be
passed._
- `window.onerror()` assumed that if an `Error` instance was passed in,
it would always have a stacktrace (i.e. its `stack` property would be
defined).
_This is not necessarily true, although it is not clear (based on the
logs) whether reported errors of this type are caused by `Error`
instance with no stacktrace or by non-string error objects which are
incorrectly treated as `Error` instances.
This commit ensures that all types of error arguments can be handled
correctly, including `Error` instances with no stacktrace and other
types of objects or primitives.
NOTE:
PR #42881 is related as it fixes handling `null` and `undefined`
arguments in the default `ErrorHandler`.

Previously, on narrow pages where the sidenav was in `over` mode, the
sidenav's backdrop only covered the main docs content but not the
floating Table of Contents (ToC) on the right. This was inconsistent and
confusing to the user, because they could interact with the ToC and
scroll to different area of the main content while the sidenav and
backdrop were still covering the content.
This commit fixes it by ensuring the sidenav backdrop covers both the
main content and the floating ToC (when present).

Previously, the condition for showing the top-menu nav-menu in the
sidenav was the same as that for switching the sidenav mode from docked
(`mode: side`) to floating (`mode: over`). Therefore, the `isWide` input
of the corresponding `NavMenuComponent` could be hard-coded to `false`
(since the component would only be shown when the sidenav was in
floating mode).
In 61f6ed2fdf, these two desicions were
decoupled, which would result in the top-menu nav-item being shown in
the sidenav while the sidenav is in docked mode (and thus the `isWide`
input should be set to `true`).
This commit fixes it by setting the `isWide` input based on the value of
the `dockSideNav` property, as happens for the rest of the nav-menus.
PR Close#42747
Previously, the `AppComponent#showTopMenu` property was taken into
account when determining the `MatSidenav#mode` value. However, this was
redundant, because in the only case in which the use of `showTopMenu`
would make a difference (i.e. when `dockSideNav` was true and
`isSideNavDoc` was false) the sidenav would be closed and the hamburger
menu button would not be visible (thus there would be no way to open it
manually).
This commit simplifies the condition for determining the sidenav mode by
removing `showTopMenu` from the expression.

This commit applies the necessary changes to make angular.io and (most)
docs examples compatible with both RxJS v6 and v7. It also adds new
steps to relevant CI jobs to test angular.io and docs examples against
RxJS v7 as well (to catch potential regressions).
NOTE:
Some of the docs examples are not compatible with RxJS v7 and are
therefore excluded from the tests. The SystemJS-based ngUpgrade
examples in particular are excluded, since they require a different
SystemJS configs to run against RxJS v6 and v7 and the extra complexity
of managing that is not worth it for the 4 affected examples.

Previously, redirects had to be configured in both the Firebase config
(`firebase.json`) and the ServiceWorker config (`ngsw-config.json`).
This made it challenging to correctly configure redirects, since one had
to understand the different formats of the two configs, and was also
prone to getting out-of-sync configs.
This commit simplifies the process of adding redirects by removing the
need to update the ServiceWorker config (`ngsw-config.json`) and keep it
in sync with the Firebase config (`firebase.json`). Instead the
ServiceWorker `navigationUrls` are automatically generated from the list
of redirects in the Firebase config.
NOTE:
Currently, the automatic generation only supports the limited set of
patterns that are necessary to translate the existing redirects. It can
be made more sophisticated in the future, should the need arise.
