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:

The APF v13 `ng_package` rule will generate the `exports` field if not
set. Currently it allows for additional subpath entries to be configured
manually. The packager does not allow for custom conditions in subpath
exports which are auto-generated.
This is sometimes useful and necessary though. e.g. in Angular Material,
we also need to expose the index Sass file through a `sass` conditional
that the Webpack Sass loader will pick up. For this, the packager needs
to support manual additional conditions (as long as they do not
conflict).

* Allows for the latest v16 NodeJS versions. This matches with the CLI

We already limit this to `>= v16.10.0` in preparation to only

In addition to the existing `exports` conditional exports we ship
as part of APF v13, we want to expose the non-bundled ESM2020 output
through the `esm2020` conditional name. Additionally we will expose
the flat ES2020 files through the `es2020` conditional field, allowing
consumers (like the CLI) to prioritize certain formats.
e.g. consider the case with RXJS where it currently defaults to
the ESM5 output. The CLI could now set `es2015` as the conditional
to leverage the ES2015 output of RXJS. This unveils a problem though
since this would also mean that `ES2015` output of the framework Angular
packages would be used instead of the available ES2020 output. Here is
the additional `es2020` conditional helpful as it allows the CLI to
prioritize `es2020`, fallback to `es2015` and lastly fallback to `default`.

Currently when `ngc-wrapped` runs in external/consumer workspaces, like
in the Angular Components project, the `ngc-wrapped` binary relies on
the linker due to the patched module resolution in `rules_nodejs` no
longer being default. The reliance on the linker of `rules_nodejs` is
problematic for workers as the required `node_modules` are not
re-linked for every build. This was previously not an issue before the
APF v13 changes because the `compiler-cli` module was loaded only once
through an import statement.
As of APF v13, the compiler-cli module is loaded dynamically for every
build. This dynamic import can then break as the worker does not
initially load the compiler-cli module when becoming online. Instead,
the module is loaded on the first build where the node modules might not
be linked properly anymore (due to e.g. other targets running at the same time).
We fix thi issue by doing the following things:
1. Enabling the patched module resolution for consumer/external
workspaces. This would match how we use ngc-wrapped inside FW as
well.
2. Caching the compiler CLI module. Instead of re-fetching the module
through dynamic imports for every build (in a worker), we should use
the cached version. This is semantically the same as with APF v12
where a single import statement at file top-level was used.
Technically, NodeJS should cache the module, but it doesn't hurt
directly caching it as the module resolution will be patched by
`rules_nodejs` and could perform unnecessary tasks.
PR Close#43690
The `@angular/core` migrations are currently published as CommonJS and also not bundled. Schematics, of which migrations are a type, are currently required to be CommonJS modules due to the Schematics Runtime not yet supporting ESM-based schematics. To ensure that the migration files are loaded as CommonJS modules, a nested `package.json` file has been introduced within the `schematics` directory of the package to set the `type` field for all containing JavaScript files as CommonJS. Since the migrations are also not currently bundled and the `devmode` output used to build the migrations will replace all relative imports with fully-qualified module specifiers, an additional `exports` entry must be added to allow the fully-qualified module specifiers to correctly resolve. If `devmode` did not change the relative imports the additional entry would not be needed. Bundling would also remedy the situation and is the long-term path, especially once the migrations are converted to ESM. Additional followup changes should investigate bundling each migration. The additional `exports` entry should be removed if either `devmode` behavior is changed or the migrations are bundled.

In the current Bazel setup, we run CommonJS as devmode output, and ESM
for prodmode output. This means that consumers of the
`@angular/bazel` package will end up using the prodmode-built ESM
package of the compiler-cli. This commit adds interop logic to be able
to load the compiler-cli as strict ESM package.
We cannot switch devmode to ESM, as this would require some changes
in `rules_nodejs` and potentially the reduction of both output flavors
into a single one (which is a future project anyway). This is out of
scope for now and inside g3, there is still devmode output as well.
PR Close#43431
As outlined in the previous commit which enabled the `esModuleInterop`
TypeScript compiler option, we need to update all namespace imports
for `typescript` to default imports. This is needed to allow for
TypeScript to be imported at runtime from an ES module.
Similar changes are needed for modules like `semver` where the types incorrectly
suggest named exports that will not exist at runtime when imported from ESM.
This commit refactors all imports to match with the lint rule we have
configured in the previous commit. See the previous commit for more
details on why certain imports have been changed.
A special case are the imports to `@babel/core` and `@babel/types`. For
these a special interop is needed as both default imports, or named
imports break the other module format. e.g default imports would work
well for ESM, but it breaks for CJS. For CJS, the named imports would
only work, but in ESM, only the default export exist. We work around
this for now until the devmode is using ESM as well (which would be
consistent with prodmode and gives us more valuable test results). More
details on the interop can be found in the `babel_core.ts` files (two
interops are needed for both localize/or the compiler-cli).
PR Close#43431
Enables the `esModuleInterop` for all TypeScript compilations in the
project. This allows us to emit proper ESM-compatible code. e.g.
consider the following import:
```ts
import * as ts from 'typescript';
```
This import currently will break at runtime in NodeJS because the
`typescript` package is not shipping ESM. It's still a CommonJS module.
ES modules are able to import from `typescript` though, using an import
statement as above, but everything in `module.exports` is being exposed
as the `default` named export. TypeScript at runtime does not have any
other named exports, so for actual ESM compatibility, all of our imports
need to be switched to:
```
import ts from 'typescript';
```
The `esModuleInterop` option allows this to work even though the
`d.ts` file of TS currently suggests that there are _only_ named exports.
The TypeScript language service will now suggest the correct import form as
shown above. It doesn't enforce that unfortunately, but this commit also
adds a lint rule that enforces certain patterns so that we emit imports
that are compatible with both ESM and CJS output (CJS still needed here
since tests run with CJS devmode output still; this is a future project
to switch that over to ESM!)

As part of v13, all APF packages use the `exports` field which defines
the public entry-points/mappings for a package. so-called package exports.
The `ng_package` rule creates all the necessary mappings/sub-path exports
for the entry-points of `@angular/common`. Though, since the locale files are
generated separately and are not an actual entry-point, we need to expose these
files publicly so that they can be imported/resolved by consumers.
PR Close#43431
Similar to other code that is shipped as part of `@angular/common`
(with APF v13), we should ship the generated locale files as ESM
files as well. This is necessary/reasonable because we explicitly
set `type: "module"` for the common package, so it makes sense to
have the same apply for the locale sub-directory.
Note: The global locale scripts remain having the `.js` extension
and will continue to be unmodified. They are CJS/ESM compatible either
way, but refer to browser globals.
PR Close#43431
The Angular Core and localize package currently use deep imports for
code that is shipped. This is problematic as we want to ship the
compiler-cli as full-ESM. To achieve this we need to use a bundler and
this breaks deep imports.
We use a bundler for the compiler CLI because for full ESM
compatibility, we would need to explicitly add the `.js` extension
to all relative imports. This is very cumbersome and prone to mistakes
so to mitigate this problem in a safe way, we bundle the compiler-cli.
Note: Deep imports continue to exist for the language service as it
bundles the compiler-cli.

This commit implements partial compilation APF v13 for the
`ng_package` rule. The changes involve the following things:
1. Requesting the partial compilation output for all targets (and
its transitives) in the `deps` or `srcs` attributes.
2. Downleveling of ES2020 prodmode output to a FESM2015 file.
3. Cleanup of file resolution. Previusly, execroot file paths (which are
passed to the packager tool) were composed manually. This is prone to
mistakes and breaks with transitions.
A lot of this code can be simplified by passing the necessary Bazel
`File` information as JSON. This also simplifies the packager tool
significantly (and makes it more readable..)
4. Remoal of UMD bundles. This also allows us remove the `globals` rule
attribute with `externals` (we do not need any UMD global identifier
names anymore).
5. The `package.json` will set the `exports` field and use subpath
exports to make module resolution work for ESM consumers.
6. TSLib is also always set as `external` now. Previously it had to be
added as `dep` to the `ng_package` rule as UMD files bundled `tslib`.
7. The `include_devmode_srcs` option has been removed. This option was
an addition to APF that allowed the `@angular/compiler` to ship
non-flattened ES5 CommonJS sources. We want to keep APF consistent
and not allow such exceptions. Compiler is now a strict APF package
as well, and the compiler-cli just needs to go through the primary
entry-point for things it needs (or it bundles the necessary parts
into the CLI.)
Overall, these are all changes. A lot of changes to make the packager
rule and tool more readable and Bazel-idiomatic were made as well. This
allows us to easier make packaging changes in the future, and it's more
future-proof if we ever change how inputs (like `ng_module` targets) are
generated (e.g. consider a case where we'd use the `ts_project` rule).

In preparation for using the partial compilation transition on the
packager, we need to be able to have a reference to the flat module
out file (that is used as "index" file for entry-point ng_module targets).
We need a reference to the file because with transitions applied, the
inputs are not necessarily in the default `bazel-out` directory. The
packager currently only guesses such paths (this worked most of the
time) but guessing the output directory with transitions will become
impossible.. so the paths need to be computed in a Bazel-idiomatic way.
This is more future-proof and correct (and more clean IMO).
