The application builder now provides structured output types to its internal
consumers. The architect builders themselves and the programmatic API is
not changed. These output result types allow for the development server to
receive additional information regarding the build and update the active
browser appropriately. This functionality is not yet implemented but the
additional result types provide the base infrastructure to enable future
features. The result types also allow for reduced complexity inside other
builders such as i18n extraction and the browser compatibility builder.
The usage is not yet fully optimized and will be refined in future changes.
The Node.js types (`@types/node`) now contains the information for the `Response`
class and the global `fetch` function. The `Response` object is also globally
accessible in all versions of Node.js supported by the Angular CLI. This removes
the need to depend directly on the `undici` package.
The `undici` package is still used for unit-testing and remains as a development
dependency.
This commit reduces the maximum number of workers to the available CPUs minus 1. This adjustment ensures that some resources are left for the main thread, preventing it from being starved of CPU cycles.
Several smaller code changes to improve type information and remove now
unneeded code structures based on improvements to both Node.js, TypeScript,
and underlying dependencies.
Due to bazel rules_nodejs caching, several additional `JSON.parse` usages were not
caught in the first set of fixes. These have now been addressed. Also,
the `must-use-promises` rule has been patched to match the behavior of the
`@typescript-eslint/no-floating-promises` for consistency.
The bazel option `suppressTsconfigOverrideWarnings` was also removed from the
`tsconfig` as it is a no-op and was previously used for now removed feature.
Test files are currently excluded from the `JSON.parse` rule to avoid large
changes to test code.
The TypeScript `isolatedModules` option is now enabled for all TypeScript
code within the repository. As a result, all packages will now be built
with the option enabled. This does not affect projects created with the CLI
and is only related to the building of the actual Angular CLI code.
The `isolatedModules` option ensures that code can be emitted without the
TypeScript typechecker and allows tools other than TypeScript to potentially
be used. Code was updated to correct all errors after the option was enabled.
Additionally, some early code fixes were done to add function and accessor
return types to prepare for future `isolatedDeclarations` usage. More changes
would be needed to consider turning on `isolatedDeclarations`, however.
The Node.js `os.availableParallelism` API now provides more accurate values
when used within containers such as many CI environments. This provides a
better default when using resource limited CI setups. The value is still
set to a maximum default of four. However, the `NG_BUILD_MAX_WORKERS`
environment variable can be used to set the value to an explicit value
if required.
The `istanbul-lib-instrument` package provides the required functionality needed
to instrument code for test coverage within the context of the Angular CLI.
Since the build pipeline already contains a customized babel preset, this package
can be integrated directly into the pipeline.
This reduces the number of dependencies required for `@angular-devkit/build-angular`
including the deprecated `inflight` package.
In this commit, the custom implementation of a promise-based setTimeout function has been replaced with the native Node.js setTimeout function, which now returns a promise.
Updates for all angular.io links to the new angular.dev domain. Additionally, adjustment to new resources where the equivalent does not exist on the new site (e.g. Tour of Heroes tutorial)
This commit introduces an `--inspect` option to the dev-server, enabling debugging of server-side code when using SSR or SSG. This option is equivalent to `node --inspect=[[host:]port]`.
Usage examples:
```
$ ng serve --inspect
$ ng serve --inspect 9999
$ ng serve --inspect localhost:9999
```
Closes: #27773
