When using the experimental esbuild-based browser application builder, babel transformation
is now only performed on a file if the file requires the specific transformations enabled
for the build. This has the benefit of removing the need to parse and process files that
will not be affected by the enabled transformations.
From initial testing, this provides a 30% build time improvement for development builds of a
newly generated application and a 10% improvement for production builds.
esbuild now allows specifying whether individual JavaScript features should be supported in addition
to specifying the target JavaScript version for the output. This capability is now used to provide
the native async/await downleveling that is required by Zone.js when using the experimental esbuild-
based browser application builder. Since esbuild does not yet support downleveling async iteration
or async generators, Babel is still used when either of these syntax features are detected.
Previously, the RegExp didn't correctly handle cases where data URIs had escaped quotes like the below
```css
url("data:image/svg+xml;charset=utf-8,<svg width=/"16/" height=/"15/"></svg>")
```
Closes#23680
This dependency is only used to valid that node packages are resolved correctly.
With this change we mock the structure of font-awesome to avoid having to install it.
With this commit, we add a middleware that handles preflight requests as currently responses for this type of requests returning 404.
This is a temporary workaround until this issue is fixed upstream. See: https://github.com/webpack/webpack-dev-server/issues/4180Closes#23639
The dev-infra build tooling is now decoupled from `ng-dev`. This will
make it easier to update `ng-dev` without necessarily needing to upgrade
the whole build system, Bazel etc. This is useful when e.g. new release
tool features have been added and should also be ported to active LTS
branches.
The esbuild-based experimental builder will now leverage the bundler to perform resolution of CSS imports.
This allows for more comprehensive resolution including packages which use the `sass` and/or `style` custom
conditions within a `package.json` exports field.
This PR includes a webpack plugin which adds a field to source maps that identifies which sources are vendored or runtime-injected (aka third-party) sources. These will be consumed by Chrome DevTools to automatically ignore-list sources.
When vendor source map processing is enabled, this is interpreted as the developer intending to debug third-party code; in this case, the feature is disabled.

The `sourcemap.vendor` build option for the esbuild-based browser application builder will now
properly be considered when processing sourcemaps for third-party code (code originating from
a `node_modules` directory).
This change adjusts the virtual output directory of the configuration for the experimental esbuild-based
browser application builder to be based on the workspace root. This allows esbuild to generate sourcemap
source paths that are relative to the workspace root and that do not contain path information from outside
the workspace root.
Instead of generating the content hash based on the content of scripts BEFORE the optimization phase,
the content hash is generated AFTER the optimization phase.
Prevents caching issues where browsers block execution of scripts due to the integrity hash not matching
with the cached script in case of a script being optimized differently than in a previous build,
where it would previously result in the same content hash.
Fixes#22906
This change adds support for using Sass stylesheets within an application built with the experimental
esbuild-based browser application builder. Global stylesheets (`styles` build option) and component
stylesheets (`@Component({ styleUrls: [...], ...})`) with Sass can now be used.
The `stylePreprocessorOptions.includePaths` option is also available for Sass stylesheets.
Both the default format (`.scss`) and the indented format (`.sass`) are supported.
Inline component stylesheet support is not yet available with the esbuild-based builder.
The hidden stylesheet option was incorrectly being ignored for component
stylesheets when using the experimental esbuild-based browser application
builder. The hidden option will now correctly not include the stylesheet
comment within the stylesheet text for components.
By default, a glob pattern starting with a forward slash will be "mounted" onto the system root. This causes globs to escape the workspace root.
With this change we configure disable glob "mounting" and also change the root to the same setting of the `cwd`.
Closes#23467
With this change we remove the usage of hard coded `src` directory and instead infer this from the `sourceRoot` project option.
We also remove the `angularCompilerOptions.entryModule` property in the server tsconfig as this is no longer needed with Ivy.
Closes#12104
When using localization we setup `SIGINT` signal to delete the temporary directory. In some cases this resulted in delaying the process from exiting a couple of seconds.
Closes#22216
During testing architect isn't spawned as a new process therefore we the global state can be tained from previous runs.
`es5TargetWarningsShown` which was saved in the global state caused flakiness.
Since version 4, webpack-dev-server by default will shutdown gracefully. This results in `CTRL+C` needed to be pressed multiple times to exit the process.
See: c76b6d11a3/lib/Server.js (L1801-L1827)Closes#22216
This commit add a new `externalDependencies` option to the experimental browser builder.
Dependencies listed in this option will not be included in the final bundle, instead the user would need to provide them at runtime using import maps or another method.
Closes#23322
Service worker augmentation of an application is now supported when using the experimental
`browser-esbuild` application builder. Both the `serviceWorker` and `ngswConfigPath` options
are now available for use.
The implementation leverages the `augmentAppWithServiceWorker` internal function that is used
by the Webpack-based builder. This function currently reads the application files from the
filesystem after all the application files are written. With the `browser-esbuild`builder, all
application files are available in-memory. This can allow a future version of the service worker
code to avoid additional file access and further improve build time performance when using a
service worker. Future work will investigate the creation of an `augmentAppWithServiceWorker`
variant that supports accessing these in-memory files.
Prepares the `@angular-devkit/build-angular` package for the eventual change of enabling the
TypeScript `useUnknownInCatchVariables` option. This option provides additional
code safety by ensuring that the catch clause variable is the proper type before
attempting to access its properties. Similar changes will be needed in the other
packages in the repository prior to enabling `useUnknownInCatchVariables`.
