@angular/ssr

A thin re-export shell for the SSR adapter. The bulk of SSR functionality lives in @angular/platform-server and the build-tool integration in @angular/build (shipped from the angular/angular-cli repo). @angular/ssr is the public API surface most apps import.

Purpose

@angular/ssr provides:

• The AngularNodeAppEngine / AngularAppEngine classes that adapt rendered HTML for use behind an Express, Hono, or Cloudflare Workers handler.
• Helpers for static site generation (SSG) builds.
• Stable re-exports of the underlying server-rendering APIs.

This package exists primarily as a stable import surface so application code doesn't depend directly on platform-server internals.

The package itself is mostly stubs (~26 lines of TypeScript). The active code lives in @angular/build (CLI repo) and @angular/platform-server.

Status

Versioned within the CLI release cycle (22.0.0-next.6 at this writing). Apps that use server-side rendering depend on this package, but contributors making framework changes typically work in platform-server instead.

Entry points for modification

• For SSR runtime changes: see packages/platform-server.
• For SSR build-system changes: contribute to angular/angular-cli's @angular/build package.
• For the public API surface here: edit packages/ssr/public_api.ts and update the matching golden.
