The compiler host would force any file that is in node_modules
into the list of files that needed to be type checked which
captures .js files if `allowJs` is set to `true`. This should
have only forced .d.ts files into the project to enable
generation of factories.
Fixes: #19757
Currently the Service Worker checks for updates only on SW startup,
an event which happens frequently but also nondeterministically. This
makes it hard for developers to observe the update process or reason
about how updates will be delivered to users. This problem is
exacerbated by the DevTools behavior of keeping the SW alive
indefinitely while opened, effectively preventing the page from
updating at all.
This change causes the SW to additionally check for updates on
navigation requests (app page reloads). This creates deterministic
update behavior, and is much easier for developers to reason about.
It does leave the old update-on-SW-startup behavior in place, as
removing that would be a breaking change.

This allows examples to be found during aio's `yarn serve-and-sync`, which only
looks for examples in `packages/examples/<packageName>/**/*`, where
`packageName` is the name of the package that the modified file belonged to;
e.g. `core`, `common`, etc.).
Closure Compiler cannot infer that the swtich statement is exhaustive,
which causes it to complain that the method does not always return a
value.
Work around the problem by throwing an exception in the default case,
and using the `: never` type to ensure the code is unreachable.
Due to an overly agressive assert the compiler would generate
an internal error when referencing an enum declared in
namspace.

Previously, this code would unconditionally add a @fileoverview
comment to generated files, and only if the contained any code at all.
However often existing fileoverview comments should be copied from the
file the generated file was originally based off of. This allows users
to e.g. include Closure Compiler directives in their original
`component.ts` file, which will then automaticallly also apply to code
generated from it.
This special cases `@license` comments, as Closure disregards directives
in comments containing `@license`.

Since our version of Chromium is also pinned, a new ChromeDriver (that
drops support for our Chromium version) can cause random (and unrelated
to the corresponding changes) errors on CI.
This commit pins the version of ChromeDriver and it should now be
manually upgraded to a vrsion that is compatible with th currently used
Chromium version.

For some reason, prior to this fix, the boolean set matching
code (within `animation_transition_expr.ts`) failed to remain
the same when compiled with closure. This refactor makes sure
that the code stays in tact.

Closure Compiler by default will report diagnostics from type checks in
any JavaScript code, including code emitted by the Angular compiler.
Disabling `checkTypes` substantially reduces warning spam for users, and
allows them to run with stricter compiler flags (e.g. treating actual
diagnostics from user code as errors).
Closure Compiler will still type check the code and use types (where
found and correct) for optimizations.

Service Worker can't be compiled with use of Closure Compiler
PR Close#20800
Not every application is served from the domain root. The Service
Worker made a bad assumption that it would be, and so requested
/ngsw.json from the domain root.
This change corrects this assumption, and requests ngsw.json without
the leading slash. This causes the request to be interpreted
relative to the SW origin, which will be the application root.
The Service Worker contains a mechanism by which it will postMessage
itself a signal to initialize its caches. Through this mechanism,
initialization happens asynchronously while keeping the SW process
alive.
Unfortunately in Firefox, the SW does not have the ability to
postMessage itself during the activation event. This prevents the
above mechanism from working, and the SW initializes on the next
fetch event, which is often too late.
Therefore, this change has the application wait for SW changes and
tells each new SW to initialize itself. This happens in addition to
the self-signal that the SW attempts to send (as self-signaling is
more reliable). That way even on browsers such as Firefox,
initialization happens eagerly.
Currently a bug exists where attempting to inject SwPush crashes the
application if Service Workers are unsupported. This happens because
SwPush doesn't properly detect that navigator.serviceWorker isn't
set.
This change ensures that all passive observation of SwPush and
SwUpdate doesn't cause crashes, and that calling methods to perform
actions on them results in rejected Promises. It's up to applications
to detect when those services are not available, and refrain from
attempting to use them.
To that end, this change also adds an `isSupported` getter to both
services, so users don't have to rely on feature detection directly
with browser APIs. Currently this simply detects whether the SW API
is present, but in the future it will be expanded to detect whether
a particular browser supports specific APIs (such as push
notifications, for example).
Currently, the way to not use the SW is to not install its module.
However, this means that you can't inject any of its services.
This change adds a ServiceWorkerModule.disabled() MWP, that still
registers all of the right providers but acts as if the browser does
not support Service Workers.
Saving `oldProgram` in `AngularCompilerProgram` instances is causing a memory leak for unemitted programs.
It's not actually used so simply not saving it fixes the memory leak.

This changes XhrBackend to not strip the XSSI prefix from error text
if such a prefix is present but the remaining body does not parse as
JSON.
PR Close#19958
Previously, XhrBackend would call JSON.parse('') if the response body was
empty (a 200 status code with content-length 0). This changes the XhrBackend
to attempt the JSON parse only if the response body is non-empty. Otherwise,
the body is left as null.

Previously, HttpClient used the overly clever test "body || null"
to determine when a body parameter was provided. This breaks when
the valid bodies '0' or 'false' are provided.
This change tests directly against 'undefined' to detect the presence
of the body parameter, and thus correctly allows falsy values through.
