* build: disconnect `@npm` workspace from main project
This will speed up significantly as we don't need to fetch all
dependencies again just for the `@npm` repository that is at this point
only leveraged by the `ng_package` rule for some of its dependencies.
This commit allows us to drop the `yarn.lock` and Aspect lock files, and
allows us to independently migrate `ng_package` to `rules_js`.
It also allows us to drop the `_rjs` TS interop layer in follow-up commits.
* build: drop `_rjs` suffix from `ts_project` targets
We don't need the `ts_project` interop in principle
at this point. We only have one remaining instance left for the SSR
`ng_package` integration. This commit cleans up all usages.
* build: remove yarn
* build: avoid duplicated dependencies at top-level
`rules_js` seems to be sensitive if there are similar versions of the same
package installed, but with differently matched peer dependencies. This
is fine because we can (and should long-term) move those dependencies to
their package-local `package.json` files. This commit unblocks the
migration and highlights how we can move deps to the individual packages
in the future.
* build: update checkout github action
This will allow us to use pnpm.
* build: update node to avoid strict-engines error caused by `npm`
Avoids:
```
Lockfile is up to date, resolution step is skipped
ERR_PNPM_UNSUPPORTED_ENGINE Unsupported environment (bad pnpm and/or Node.js version)
Your Node version is incompatible with "npm@11.2.0".
Expected version: ^20.17.0 || >=22.9.0
Got: v20.11.1
```
Note that we won't update the WORKSPACE test version as that would mean
we need to update the Node engines for shipped packages; and we can't do
this right now without introducing a breaking change.
* build: fix missing dependency for spec bundling
The beasties JS sources weren't available for bundling in the
`bazel-bin`, and this surfaced in RBE. This commit fixes this.
As part of go/ng:windows-dev-future, we are changing how our
infrastructure supports Windows build & testing. Clearly:
- we will still support contributors on Windows, and we believe we will
be improving and streamlining the experience here
- we will continue testing the Angular CLI for our Windows users. We are
aware of the many Windows users using the `ng` CLI.
What is changing? We are no longer actively working towards a Bazel infrastructure
that supports native Windows building and testing. There are currently
two ways to contribute to Angular on Windows. That is via WSL, or via
e.g. native Windows cmd.exe, with Git Bash on top. We acknowledge that
the latter worked sometimes, but we also realize it very often breaks as
nobody on our team uses, verifies it, and it introduces extra complexity
because Bazel on Windows is quite disconnected from Linux/Mac (e.g. no
sandboxing). Going forward, to improve our team's effectiveness, and
improve our stability guarantees for Windows (and Windows contributors),
we are actively discouraging the use of Git Bash for contributing to
Angular; but instead ask for WSL to be used. I can speak as one of the
few long-term team members that have worked on Windows (without WSL) most
of my time, that WSL is great and the contributing experience is much
smoother and also easier to "guide". It's a positive change because we
won't be suggesting "two ways to contribute on Windows", where in
reality one is very brittle and can break at any time!
---
For testing of the Angular CLI: We will continue to maintain the
capability to cross-compile via Bazel with Windows as the target
platform. This allows us to build the e2e tests for Windows, and run
them natively outside WSL to ensure native Windows `ng` CLI testing!
This is what this change mostly does.
Notably, two things are missing here and will be followed up:
- caching of the e2e tests on Windows is not properly functioning yet.
- caching of the WSL node modules + nvm is not working properly yet.
Other than that, we are seeing very similar timing and results of the
Windows tests, so this change unblocks our `rules_js` migration.
BREAKING CHANGE: The `NodePackageLinkTask` has been removed without a replacement. Create a custom task if needed.
Note: This does not affect application developers.
* Updates the repo to TypeScript 5.8 final.
* Updates the vendored TypeScript binary to 5.8 final.
* Switches the newly-generated projects to TypeScript 5.8.
Node.js v18 will reach its End-of-Life on 2025-04-30 and as a result will
not be supported with the upcoming Angular v20.
Node.js Release Schedule: https://github.com/nodejs/release#release-schedule
BREAKING CHANGE: Node.js v18 is no longer supported with Angular.
Before updating a project to Angular v20, the Node.js version must be
at least 20.11.1. For the full list of supported Node.js versions,
see https://angular.dev/reference/versions.
An `application` only variant of the `karma` builder found within the
`@angular-devkit/build-angular` package is now available within the
`@angular/build` package as `@angular/build:karma`. This builder will
only use the `application` builder found within `@angular/build` and
does not provide the `builderMode` option as `application` would be the
only valid value. Testing behavior is effectively equivalent to using the
`@angular-devkit/build-angular:karma` builder with the `builderMode`
option set to `application`. However, several options have been adjusted:
* `builderMode` was removed
* `fileReplacements` legacy structure (`src`/`replaceWith`) removed
* `polyfills` only accepts an array of strings
* `loader` has been added
* `define` has been added
* `externalDependencies` has been added
Adding explicit type information for function return types is needed
to allow the `@angular-devkit/core` package to eventually be built with
the `isolatedDeclarations` option.
Migrates the `@angular-devkit/build-angular` tests to `rules_js`. This
was a rather larger undertaking as the tests were very reliant on e.g.
the directory structure or specific node module layout; so some changes
were needed.
- the Sass files include a much larger file header now. That is because
the npm Sass files have much larger paths, given being inside a
symlinked pnpm store directory. E.g.
```

- Similarly to above, hashed chunk files can change given different
paths of e.g. Webpack, or external sources.
- Tests for verifying the lazy module chunks may enable
`preserveSymlinks` just to make the chunk names shorter and easier to
verify, avoiding truncatd super long paths to the e.g. pnpm stores
again.
- the ngsw-worker.js file cannot be copied using `copyFile` as that
results in permissions being copied as well. In Bazel, now that
the npm files are properly captured, are readonly, so subsequent
builds (e.g. the watch tests) will fail to copy/override the file
again! Reading and writing the file consistently seems appropriate.
- Tests relying on puppeteer and webdriver-manager worked in the past,
by accident, because postinstall scripts (from e.g. puppeteer) were
able to modify content of other packages (e.g. the puppeteer-core
cache of browsers then). This does not work with `rules_js` anymore,
so we need to keep the cache local to the puppeteer postinstall
script. This requires a little trickery right now to ensure resolution
of the browsers at runtime works..
- server tests did miss the `node` types to be explicitly listed (as
they would be in a fresh project), and this caused failures. Likely
because we no longer patch resolution.
- avoid npm-module style imports from tests within the same package.
This is not allowed with `rules_js` and also is inconsistent.
To support usage of the newly released Tailwind CSS 4.0.0, the peer dependency
range has been update to include `^4.0.0`. This prevents potential installation
warnings/error when using various package managers.
Use of Tailwind CSS 4+ requires either the `application` (new project default) or
`browser-esbuild` builder. Both of which support custom postcss configuration
via a `.postcssrc.json` file.
For instructions on the setup of Tailwind CSS with Angular, please see the
Tailwind CSS documentation here: https://tailwindcss.com/docs/installation/framework-guides/angular
