The logic that generates first argument for the `elementStyling` instruction was missing the check that directive expression is specified. As a result, in some cases first argument was not added, thus making function invocation incorrect. Now the presence of directive expression is taken into account and the `null` expression is generated as needed.

In some applications, developers define a `ts_library` that just consists of `d.ts` files (e.g. to type `module.id`; see: https://github.com/angular/material2/blob/master/src/module-typings.d.ts), and expect the `esm5.bzl` file to not throw an error like:
```
target.typescript.replay_params.outputs
struct' object has no attribute 'outputs'
```
The "replay_parameters" property will exist in that case, but is set to "None" because there is no action that should be replayed in favor of producing ES5 outputs. See: https://github.com/bazelbuild/rules_typescript/pull/326. Notice that this right now breaks similarly because an empty `struct()` is returned that does not have a property called `outputs`. [#326](https://github.com/bazelbuild/rules_typescript/pull/326) fixes that by being explicit that there is no _action_ at all.

Prior to this change `projectDef` instructions were placed to root templates only, thus the necessary information (selectors) in nested templates was missing. This update adds the logic to insert `projectDef` instructions to all templates where <ng-content> is present.

Previously ngtsc assumed resource files (templateUrl, styleUrls) would be
physically present in the file system relative to the .ts file which
referenced them. However, ngc previously resolved such references in the
context of ts.CompilerOptions.rootDirs. Material depends on this
functionality in its build.
This commit introduces resolution of resources by leveraging the TypeScript
module resolver, ts.resolveModuleName(). This resolver is used in a way
which will never succeed, but on failure will return a list of locations
checked. This list is then filtered to obtain the correct potential
locations of the resource.

This commit adds support for resolution of styleUrls to ngtsc. Previously
this field was never read, and so components with styleUrls would appear
unstyled after compilation.

When a single resource is preloaded twice in ngtsc, the second request
would be recognized as in-flight in which case `undefined` would
be returned, which signals to the compilation that is can resume
synchronously. The compilation would then proceed immediately and call
`load`, only to find out that the request is still in-flight which is
not allowed.
This commit caches the Promise of the in-flight fetch requests, such
that subsequent preload requests can return the corresponding Promise
instance.

* Currently when building a `ng_module` with Bazel and having the flat module id option set, the flat module files are not being generated because `@angular/compiler-cli` does not properly determine the entry-point file.
Note that this logic is not necessarily specific to Bazel and the same problem can happen without Bazel if multiple TypeScript input files are specified while the `flatModuleIndex` option has been enabled.

Currently when building the `ng_package` multiple times, the old `ng_package` output will be copied over to the new `ng_package` content. Resulting in packages like `src/cdk/npm_package/npm_package/npm_package/AND_MORE`.
This happens because currently all TypeScript definition files are resolved from within the `binDir`. This is just wrong because it could then take up the `d.ts` files from the previous `ng_package` output. All typescript definitions that belong to the target package, should be resolved through Bazel and copied based on that computation.
Also fixes that `esm` files aren't written to the `ng_package` on Windows. This is because we try to flatten paths using the `path.delimiter` while the path is always using Posix delimiters (causing the paths to be incorrect)

* Currently when building the ES5 and ES2015 output, `ngc_wrapped` will fail because it tries to write the `fs.openSync` the tsickle output file at the same time. This causes a runtime exception in Windows and can be fixed by just writing the externs for ES5 mode to the proper ES5 "output root".

Ngcc will now render additional exports for classes that are referenced in
`NgModule` decorated classes, but which were not publicly exported
from an entry-point of the package.
This is important because when ngtsc compiles libraries processed by ngcc
it needs to be able to publcly access decorated classes that are referenced
by `NgModule` decorated classes in order to build templates that use these
classes.
Doing this re-exporting is not without its risks. There are chances that
the class is not exported correctly: there may already be similarly named
exports from the entry-point or the class may be being aliased. But there
is not much more we can do from the point of view of ngcc to workaround
such scenarios. Generally, packages should have been built so that this
approach works.
PR Close#26906
There are a number of variables that need to be passed around
the program, in particular to the renderers, which benefit from being
stored in well defined objects.
The new `EntryPointBundle` structure is a specific format of an entry-point
and contains the compiled `BundleProgram` objects for the source and typings,
if appropriate.
This change helps with future refactoring, where we may need to add new
properties to this object. It allows us to maintain more stable APIs between
the constituent parts of ngcc, rather than passing lots of primitive values
around throughout the program.
PR Close#26906
The `NgModuleDecoratorHandler` can now register all the references that
it finds in the `NgModule` metadata, such as `declarations`, `imports`,
`exports` etc.
This information can then be used by ngcc to work out if any of these
references are internal only and need to be manually exported from a
library's entry-point.

By inverting the relationship between `EntryPointPaths` and

If a decorated class is not publicly exported via an entry-point then the
previous approach to finding the associated typings file failed.
Now we ensure that we extract all the class declarations from the
dtsTypings program, even if they are not exported from the entry-point.
This is achieved by also parsing statements of each source file, rather
than just parsing classes that are exported from the entry-point.
Because we now look at all the files, it is possible for there to be multiple
class declarations with the same local name. In this case, only the first
declaration with a given name is added to the map; subsequent classes are
ignored.
We are most interested in classes that are publicly exported from the
entry-point, so these are added to the map first, to ensure that they are
not ignored.

In Angular, it used to be an accepted practice to use strings as dependency
injection tokens. E.g. {provide: 'test', useValue: 'provided'}. However,
the Ivy node injection system did not support this. The Ivy DI system
attempts to patch a Bloom bit index onto each type registered with it, and
this patch operation does not work for a string token.
This commit adds string token support to the bloom filter system by
reserving bit 0 for string tokens. This eliminates the need for each string
token to store its own Bloom bit, at the expense of slightly more expensive
lookups of string tokens.

load("@build_bazel_rules_typescript//:package.bzl", "rules_typescript_dependencies")
rules_typescript_dependencies()
load("@build_bazel_rules_nodejs//:package.bzl", "rules_nodejs_dependencies")
rules_nodejs_dependencies()

Previously the concept of multiple directives with the same selector was
not supported by ngtsc. This is due to the treatment of directives for a
component as a Map from selector to the directive, which is an erroneous
representation.
Now the directives for a component are stored as an array which supports
multiple directives with the same selector.
Testing strategy: a new ngtsc_spec test asserts that multiple directives
with the same selector are matched on an element.

BREAKING CHANGE:
The public API for `DebugNode` was accidentally too broad. This change removes
1. Public constructor. Since `DebugNode` is a way for Angular to communicate information
on to the developer there is no reason why the developer should ever need to
Instantiate the `DebugNode`
2. We are also removing `removeChild`, `addChild`, `insertBefore`, and `insertChildAfter`.
All of these methods are used by Angular to constructor the correct `DebugNode` tree.
There is no reason why the developer should ever be constructing a `DebugNode` tree
And these methods should have never been made public.
3. All properties have been change to `readonly` since `DebugNode` is used by Angular
to communicate to developer and there is no reason why these APIs should be writable.
While technically breaking change we don’t expect anyone to be effected by this change.

This fixes an issue where a value would hide the type.
```
export interface Foo {
someMethod(): void;
}
export const Foo: Function = ...;

In the above example the `Foo` constant will hide the `interface Foo` symbol.
This change properly saves the interface in addition to the type.

A recent commit (probably 2c7386c) has changed the import graph of the
DI types in core, and somehow results in the ngc compiler deciding to
re-export core DI types from application factories which tangentially
use inject(). This is not really surprising; ngc's import graph can be
very unstable.
However, this results in a re-export of InjectFlags surviving JS
compilation. InjectFlags was a const enum, akin to an interface in TS,
with no runtime repesentation. This causes a warning to be emitted by
Webpack when it sees the re-export of InjectFlags.
This commit avoids the issue by removing 'const' from the declaration
of InjectFlags, causing it to have a runtime value. This is a temporary
fix. The real fix will be for ngc to no longer write exports of const
enums.
Testing strategy: manually verified. Due to the problem only manifesting
when recompiling after a change and then running Webpack, there is no
existing framework via which this could be easily tested with an
integration test. Additionally, the potential for this issue is gone in
Ivy, so this solution is only temporarily needed.
Fixes#27251.
