The options to generate NgFactory and NgSummary files were added to Ivy for backwards compatibility with ViewEngine. Since ViewEngine was deprecated and removed, the NgFactory and NgSummary files are no longer used as well.
This commit drops obsolete options to generate NgFactory and NgSummary files. Also, the logic that generates those files is also removed.

The `ng_package` rule supports replacing `0.0.0-PLACEHOLDER`
in license files that are inserted as part of rollup. This
requires additional logic to detect stamping, reading the status
files and then replacing the placeholder.
All of this already handled as part of normal package substitutions
and we can replace this unnecessary complexity.

This is no longer needed in google3 and actively impedes prodmode tests. See http://b/254054103#comment7 for deeper analysis.

Prior to this change the FESM bundles for the FW packages have the license banner duplicated hundreds of times in each published file.
With this change we remove all the banners from the individual input files. A new banner will be appended at the top of the FESM using rollup's banner option.
While there is a rollup plugin on NPM to strip these banners (https://github.com/mjeanroy/rollup-plugin-strip-banner) we could not use this as it does not support `.mjs`.

Fixes that we temporarily broke the Bazel npm package artifact as
part of the ESM work. This commit adjusts it and also makes the
artifact subsitutions more maintainable.

This is basically a pre-step for combining devmode and prodmode into a
single compilation. We are already achieving this now, and can claim
with confidence that we reduced possible actions by half. This is
especially important now that prodmode is used more often, but rules
potentially still using the devmode ESM sources. We can avoid double
compilations (which existed before the whole ESM migration too!).
We will measure this more when we have more concrete documentation
of the changes & a better planning document.
Changes:
* ts_library will no longer generate devmode `d.ts`. Definitions are
generated as part of prodmode. That way only prodmode can be exposed
via providers.
* applied the same to `ng_module`.
* updates migrations to bundle because *everything* using `ts_library`
is now ESM. This is actually also useful in the future if
schematics rely on e.g. the compiler.
* updates schematics for localize to also bundle. similar reason as
above.

Since this repo will now be strict ESM, and Angular Compiler packages
on NPM are also ESM-only, we can rework `ngc-wrapped` to remove
the CJS/ESM interop and we make it strict ESM too.
PR Close#48521
Currently the devmode output for `ng_module` and `ts_library` is
using ES5 CommonJS UMD. To bring it in sync with prodmode and
to start with our long-term migration to full ESM- the devmode
is updated to to ES2020 ES modules too.
This will require more tricks to make devmod work with the bazel
setup and also tests may need to be refactored given them relying
on ES5 CJS features, like for `spyOn` jasmine patching etc.
PR Close#48521
No longer maintains a separate tsconfig for the Bazel package. This
seems to be a legacy artifact back when ngc-wrapped was put into GitHub.
We now use the canonical repository Bazel tsconfig. This commit also
fixes all strictness-related errors and makes ngc-wrapped compatible.

We currently use all the ESM2020 and type sources as inputs for rollup
and type bundle actions, respectively. This is a source of slowness in
Bazel sandboxed builds because many unused files will be linked/made
available for many concurrently-running actions.
We should limit the inputs only to what is assumed to be used. We cannot
know exactly and need to include transitive types from `node_modules`,
but that is an inevitable construct with the current Bazel rules.
Note that the external node modules could still bring in a lot of files,
like in Material where the `.d.ts` files for all locales are brought
into the sandbox (from `@angular/common`). We likely would need to
remove these files in a postinstall for now, to speed up actions,
similar to how we did it for RxJS in all repositories. These are known
to be not used in the components repo.
PR Close#46187
Call tsc_wrapped's fileExists function instead of TypeScript's.
tsc_wrapped (used internally by ngc-wrapped) has an optimization under
bazel to avoid file system calls where possible. It takes advantage
bazelOpts.allowedInputs, which contains a list of all files available
for compilation.
File system calls can be quite slow depending on the file system. In
google3 I saw a 38 seconds compilation, which spent 6 seconds just doing
fs.stat calls during module resolution. Those fs.stat calls are entirely
gone after with this change.
PR Close#46069
We recently updated Babel and the Bazel types but this actually
resulted in duplicates, causing differences between what people
seen in their IDE vs. what Bazel builds.
This commit removes the lock file and generates it fully fresh,
deduping dependencies and also fixing the differences between
local IDE and Bazel.
As part of this we also need to update/fixup one assertion on the
Babel node path types, because the node start/end can now also
be `undefined`.
PR Close#45967
This change adds the capability of ngc_wrapped to emit an
unused_inputs_list file that could be used by starlark.
We are making this change because in situations where angular modules
depend on angular modules, it becomes very easy for a single change to
trigger a long cascading set of angular builds since each angular rule
depends on the transitive closure of input files.
With this change in place, and once it is properly configured, bazel
will update the set of inputs to a build rule after it is built once
removing any of the inputs specified in this list, making incremental
builds quicker by skipping any rebuilds that only had changes to unused
inputs.
This logic should be, and is likely duplicated in tsc_wrapped to solve
the same problem in pure TypeScript situations, ideally we could use the
same implementation one day.
In addition, its possible that tree artifacts are not as supported as
we'd like, and where this change should mark entire directories as
unused, we may get better performance gains by enumerating the directory
and being more explicit about specific inputs which are unused.

Speeds up the `d.ts` bundling by configuring it as a Bazel
persistent worker. Also improve logging for the ng packager
rule to make it easier to spot which actions/bundles take
up significant time.
Type bundling will occur for every entry-point so for machines
with rather limited cores/threads, this will be useful to save
NodeJS boot and resolution time.
PR Close#45900
The NodeJS Bazel linker does not work well on Windows because there
is no sandboxing and linker processes from different tests will attempt
to modify the same `node_modules`, causing concurrency race conditions
and resulting in flakiness.
PR Close#45872
Speeds up the dev-turnaround by only bundling types when packaging. Currently
bundling occurs for all the `ng_module` targets in devmode.
This has various positive benefits:
* Avoidance of this rather slower operation in development
* Makes APF-built packages also handle types for `ts_library` targets consistently.
* Allows us to ensure APF entry-points have `d.ts` _always_ bundled (working with ESM
module resolution in TypeScript -- currently experimental)
* Allows us to remove the secondary `package.json` files from APF (maybe APF v14? - seems
low-impact). This would clean-up the APF even more and fix resolution issues (like in Vite)
PR Close#45405
We recently refactored how the ng package rule deals with static files.
As part of this refactoring, transitive files outside of the current
Bazel package were flagged as errors, while previously this was just
ignored. We need to revert back this behavior (even though code remains
much simpler and predicable now) since sass library targets for example
reference all transtive files in the default info and break packages then

Fixes the dts bundling by accounting for recent API extractor changes
which made API-extractor support path mappings. This causes
cross-package and cross-entry-point imports to no longer be considered
external, resulting in the imports to be dropped.

Looks like there is some old legacy code for extracting files
from NPM packages. This is already captured by the unscoped
ESM2020 output extraction.

Non-JavaScript source-providing targets in the `ng_package` rule can throw-off
the entry-point detection and therefore should be flagged. Currently e.g.
a genrule-generated static file might unnecessarily cause additional
actions to be generated (non-breaking but just unnecessary)
PR Close#45470
Currently the `ng_package` rule does not support generated
`package.json` files. Generated `package.json` files are sometimes
useful when e.g. dependencies are automatically inserted (e.g.
many dependencies in the components repo for the MDC deps)
Currently the `package.json` files would be copied as part of
the `data` attribute, but they would not be processed. i.e. missing
out on the `exports` field and more.
We can simplify the rule attributes and make this more ergonomic.

The Bazel NodeJS rules provide two ways of accessing node modules:
* A linker which creates a `node_modules` directory in the execroot/or in the runfiles.
* A patched module resolution where no node modules directory necessarily needs to exist.
The first is the default in `rules_nodejs` and the second is technically the most idiomatic
resolution mechanism in Bazel (as it matches with a runfile resolution library).
The linker is prone to race conditions in persistent workers, or non-sandbox environments (like
windows). This is because the linker for all workers will operate on a shared `execroot` directory
and the same `node_modules` directory is modified all the time / potentially conflicting with other
linker processes from other concurrently-running workers.
We rely on the patched module resolution anyway, but just need to disable the unused linker to avoid
issues like the following:

To make our test output i.e. devmode output more aligned
with what we produce in the NPM packages, or to be more
aligned with what Angular applications will usually consume,
the devmode output is switched from ES5 to ES2015.
Additionally various tsconfigs (outside of Bazel) have been
updated to match with the other parts of the build. The rules
are:
ES2015 for test configurations, ES2020 for actual code that will
end up being shipped (this includes the IDE-only tsconfigs).
