With the update to TypeScript 3.2.x, a big issue seems to have appeared for downstream Bazel users. If the downstream user still uses a lower TypeScript version, normal Bazel targets using the `ng_module` rule are still compiled with the correct/old TypeScript version (assuming they set the `node_modules` attribute properly).
But, if they build the previous Bazel targets by specifying them within a `ng_package` rule, the TypeScript version from the Angular `workspace` is being used for the replayed ESM5 compilation. This is because we resolve the replay compiler to `ngc_wrapped` or `tsc_wrapped` Bazel executables which are defined as part of the `angular` workspace. This means that the compilers are different if the downstream user uses `ngc-wrapped` from the `@npm` repository because the replayed compilation would use the compiler with `@ngdeps//typescript`.
In order to fix this, we should just use the compiler that is defined in the `@angular//BUILD.bazel` file. This target by defaults to the "@npm" workspace which is working for downstream users. This is similar to how it is handled for `tsc-wrapped`. `tsc-wrapped` works as expected for downstream users.
**Note**: This is not the ideal solution because ideally we would
completely respect the `compiler` option from the base `ng_module`, but
this is not possible in a hermetic way, unless we somehow accept the
`compiler` as an attribute that builds all transitive deps. This is
something we should explore in the future. For now, we just fix this in
a reasonable way that is also used for `tsc_wrapped` from the TypeScript
rules.

index.html needs to have the zone.js and the project bundle injected
using script tags. This used to be done explicitly by specifying a
new index.html but with `web_package` rule introduced in rules_nodejs,
it is now possible to perform the injection dynamically.

This change is a prerequasity for a later change which will turn the
'di' into its own bazel package. In order to do that we have to:
- have `Injector` type be importable by Ivy. This means that we need
to create `Injector` as a pure type in `interface` folder which is
already a bazel package which Ivy can depend on.
- Remove the dependency of `class Injector` on Ivy so that it can be
compiled in isolation. We do that by using `-1` as special value for
`__NG_ELEMENT_ID__` which tells the Ivy `NodeInjector` than
`Injector` is being requested.

The current integration test for Bazel schematics downloads a
published version of Angular as required by the http_archive
rule in the CLI created WORKSPACE.
However, this makes the test less useful because it does not
actually test any changes to the Angular repo at source.
This PR replaces the http_archive method in the WORSPACE
with local_repository so that any local changes to the Angular
repo are tested accordingly.
With Typescript 3.2, the file e2e/src/app.po.ts generated by CLI
no longer compiles under Bazel due to missing type annotations.
A temporary file is placed in the integration/bazel-schematics
directory while the change is pending in CLI repo.

__NG_ELEMENT_ID__ static fields are a part of how the Ivy node injector
works. In order to survive closure minification correctly, they need to
be annotated with @nocollapse.
PR Close#28050
ngtsc has a hack to add @nocollapse jsdoc annotations to generated static
fields. This hack is currently broken (likely due to a TypeScript change
in the way writeFile() works).
This commit fixes the hack and introduces an ngtsc_spec test to ensure it
does not regress again.

When an @NgModule decorator executes, the module is added to a queue in
render3/jit/module.ts. Reading an ngComponentDef property causes this queue
to be flushed, ensuring that the component gets the correct module scope
applied.
In before_each.ts, a global beforeEach is added to all Angular tests which
calls TestBed.resetTestingModule() prior to running each test. This in turn
clears the module compilation queue (which is correct behavior, as modules
declared within the test should not leak outside of it via the queue).
So far this is okay. But before the first test runs, the module compilation
queue is full of modules declared in global scope. No definitions have been
read, so no flushes of the queue have been triggered. The global beforeEach
triggers a reset of the queue, aborting all of the in-progress global
compilation, breaking those classes when they're later used in tests.
This commit adds logic to TestBedRender3 to respect the state of the module
queue before the TestBed is first initialized or reset. The queue is flushed
prior to such an operation to ensure global compilation is allowed to finish
properly.
With this fix, a platform-server test now passes (previously the <my-child>
element was not detected as a component, because the encompassing module
never finished compilation.

Previously when testing code injected the Compiler, it received the
top-level Compiler implementation defined in linker/compiler.ts
(and governed by the __PRE_R3__ switch). Code running under the
TestBed, however, should always use a TestBed-aware Compiler
implementation.
This commit adds such an implementation to the TestBedRender3,
which passes compiled modules through the _compileNgModule()
function.
With this change, 3 formerly disabled router integration tests
now pass.

An @NgModule with invalid provider declarations produces errors under
normal circumstances. However, within the TestBed two small issues with
provider overrides interfered with the correct production of these errors:
1. a 'null' provider object caused a premature crash when the TestBed
attempted to check for a 'provide' property on it with hasOwnProperty().
2. the array of providers would have an empty override array appended to it
for each input provider, which would pollute the error messages produced
down the line.
This commit fixes both of these issues, by 1) checking for null and 2)
filtering out the empty override arrays.
Testing strategy: future commits change the way the TestBed compiles
modules, causing tests to become sensitive to this bug if not fixed.

An @NgModule with an 'id' property has its type registered in a global map
of modules by id. This happens during compilation of the module.
In Ivy, modules are first compiled when the @NgModule decorator executes.
In tests, they might be passed again through the TestBed's compiler,
resulting in a second compilation and registration.
Before this fix, this second registration would cause an error, as the id
was previously registered. This commit makes the registration idempotent,
so if the same module type is being registered for the same id then no
error is thrown.

modules, causing tests to become sensitive to this bug if not fixed.

Changes:
- Change the project type to `service-worker`, so that it gets
appropriate `package.json` (with `@angular/service-worker` dependency)
and `angular.json` (with `serviceWorker: true` in production config).
- Move `ngsw-config.json` to the correct directory.
- Specify custom test commands for aio's `yarn example-e2e` to also
verify that the ServiceWorker bits are set up correctly.

Previously, cli-based docs examples were tested using `yarn e2e ...`. In
some cases, it might make sense to run different or additional checks
for a docs example (when running `yarn example-e2e` in `aio/`).
Currently, the only option is to define a custom project type and
overwrite the `e2e` yarn script in `package.json`. Doing so (in addition
to being cumbersome and verbose) would also end up in the `.zip` archive
that users can download to run the example locally. This would be
confusing, if these custom tests are specific to our CI needs.
This commit adds support for defining a custom list of commands per
example. These commands (if specified) would be run instead of the
default `yarn e2e ...`, when testing the docs examples on CI (via
`yarn example-e2e`).
(This feature will be used to verify that the
`service-worker-getting-started` example is set up correctly in a
subsequent commit, but can be useful in other cases as well.)

File overwrites:
- **angular.json**: Add `serviceWorker: true` to production config.
- **package.json**: Add `@angular/service-worker` to dependencies.
This will make any `service-worker` examples work out-of-the-box, when
downloading and running locally from the `.zip` archives.

In ESM5 decorated classes can be indicated by calls to `__decorate()`.
Previously the `ReflectionHost.findDecoratedClasses()` call would identify
helper calls of the form:
```
SomeClass = tslib_1.__decorate(...);
```
But it was missing calls of the form:
```
SomeClass = SomeClass_1 = tslib_1.__decorate(...);
```
This form is common in `@NgModule()` decorations, where the class
being decorated is referenced inside the decorator or another
member.
This commit now ensures that a chain of assignments, of any length,
is now identified as a class decoration if it results in a call to
`__decorate()`.
