RESOURCE_COMPLETED_BEFORE_PRODUCING_VALUE had no guide, no JSDoc on RxResourceOptions.stream, and — since the code was positive rather than negative — could never get an auto-linked docs page even if one existed. Flip it to -991, add the NG0991 reference page, and document the "stream must emit a value or an error before completing" requirement on stream's JSDoc and in the RxJS interop guide. Also documents and tests that an unguarded template read of an errored resource's .value() propagates to the global ErrorHandler, and recommends guarding with .hasValue() as defense in depth. httpResource can throw the same error, but for a different reason: its internal request Observable isn't something app code writes directly, so an empty completion there is almost always an HttpInterceptor swallowing the response (catchError(() => EMPTY)) rather than a stream authored in the resource() call itself. The page covers both APIs with guidance matched to what's actually going on for each.
Angular.dev
This site is built with Angular.
The content is written primarily in Markdown format located in src/content. For simple edits, you can directly edit the file on GitHub and generate a Pull Request.
Local Development
For local development, pnpm is the preferred package manager. You can set up a local environment with the following commands :
# Clone Angular repo
git clone https://github.com/angular/angular.git
# Navigate to project directory
cd angular
# Install dependencies
pnpm install
# Build and run local dev server
# NOTE: Initial build will take some time
pnpm adev

FAQs
The build is failing and I'm seeing bazel:bazel failed: missing input file messages.
This is most likely due to a bazel dependency / caching issue. To resolve this, run the following command:
# Try this first
pnpm bazel clean
# If that doesn't work, try it with the expunge flag
pnpm bazel clean --expunge
High level architecture
The angular.dev website is a modern Angular application that utilizes Static Site Generation (SSG) to deliver pre-rendered, high-performance content to users.
The architecture is designed for efficiency and maintainability:
Content Sources: The documentation is sourced from two main places within the monorepo. The guides and tutorials are written in Markdown files, while the API reference pages are automatically generated by extracting documentation directly from the TypeScript source code of the Angular framework packages.
Build Process: During the build process, the Markdown files are converted into HTML. Simultaneously, the API documentation is extracted from the code comments. This content is then integrated into the Angular application.
