`@angular/platform-server` provides the foundation for rendering an
Angular app on the server. In order to achieve that, it uses a
server-side DOM implementation (currently [domino][1]).
For rendering on the server to work as closely as possible to running
the app on the browser, we need to make DOM globals (such as `Element`,
`HTMLElement`, etc.), which are normally provided by the browser,
available as globals on the server as well.
Currently, `@angular/platform-server` achieves this by extending the
`global` object with the DOM implementation provided by `domino`. This
assignment happens in the [setDomTypes()][2] function, which is
[called in a `PLATFORM_INITIALIZER`][3]. While this works in most cases,
there are some scenarios where the DOM globals are needed sooner (i.e.
before initializing the platform). See, for example, #24551 and #39950
for more details on such issues.
This commit provides a way to solve this problem by exposing a
side-effect-ful entry-point (`@angular/platform-server/init`), that
shims the `global` object with DOM globals. People will be able to
import this entry-point in their server-rendered apps before
bootstrapping the app (for example, in their `main.server.ts` file).
(See also [#39950 (comment)][4].)
In a future update, the [`universal` schematics][5] will include such an
import by default in newly generated projects.

Previously, if an entry-point had no public exports (such as the

Since #39853, it is possible to deploy to multiple Firebase sites from a

alias (`aio`) with a site. This is done via the `firebase target:apply`

associates the alias with many sites, which subsequently fails during
deployment ([example failure][1]), since the `firebase deploy` command
does not know what site to deploy to.

Currently there is an issue with redirecting `rc.angular.io` to
`angular.io` when there is no active RC. If a user has visited
`rc.angular.io` before and has a ServiceWorker registered for that
subdomain, they will never "see" the redirect to `angular.io`.
This commit fixes the problem by doing an additional deployment from the
stable branch to the `rc-angular-io-site` Firebase site when there is no
active RC. This additional deployment will ensure that:
1. Users will be temporarily redirected from `rc.angular.io` to
`angular.io`.
2. Users with a registered ServiceWorker (who don't see the redirect)
will have their ServiceWorker unregistered on the next visit.
3. The content on both sites is identical.
See #39760 for more details on the problem and the solution.

As mentioned in #39760, for this fix to take affect, we need to remove

Previously, a branch would be deployed as `archive` even if it had a
major version that was equal/higher than that of the stable branch (as
long as it was not the RC branch - i.e. not the most recent minor
branch). For example, with `11.0.x` as the stable branch and `12.0.x`
as the RC branch, `11.1.x` would be deployed as archive.
Theoretically, we should never find ourselves in such a situation.
Typically, there will only be at most one minor branch most recent than
the stable one (and that branch will be the RC branch). However, it
is possible under unusual circumstances.
This commit adds additional checks to guard against this problem. It

Previously, the `deploy()` function in `deploy-to-firebase.js` would
also perform other operations (beyond deploying), such as building the
app, checking the generated payload size, testing the PWA score of the
deployed app.
This commit decouples these operations, so that deploying can be
performed independently.
NOTE:
In a subsequent commit, this will be leveraged fix an issue with
`rc.angular.io` redirects in the presence of a ServiceWorker by
deploying the same artifacts to multiple Firebase projects/sites.
See #39760 for more details.
