Packages

Every npm package shipped from this repo. The list is exhaustive — what isn't here, isn't published.

Package	What it is	Detail page
@angular/core	The runtime: Ivy, change detection, DI, signals, hydration.	core
@angular/compiler	The template parser and IR-emitter that produces Ivy instructions.	compiler
@angular/compiler-cli	The ngtsc TypeScript plugin and ngc CLI. Includes the partial-compilation linker and template type-checker.	compiler-cli
@angular/common	NgIf/NgFor/NgSwitch/AsyncPipe, HttpClient, location services, locales, image directive.	common
@angular/router	The router service, RouterOutlet, Router events, route guards.	router
@angular/forms	Reactive and template-driven forms, plus the new signal-based forms.	forms
@angular/platform-browser	DOM renderer + browser bootstrap (bootstrapApplication).	platform-browser
@angular/platform-browser-dynamic	JIT bootstrap for the browser (mostly legacy).	platform-browser-dynamic
@angular/platform-server	SSR/SSG renderer using domino for a Node-side DOM.	platform-server
@angular/animations	Animations DSL and runtime.	animations
@angular/elements	Compiles components to Custom Elements.	elements
@angular/language-service	Editor support: completions, diagnostics, hover, refactors.	language-service
@angular/localize	Build-time and runtime i18n.	localize
@angular/service-worker	The Angular SW for offline / caching.	service-worker
@angular/ssr	Re-export shell for the SSR adapter (the bulk of SSR lives in platform-server and @angular/build).	ssr
@angular/upgrade	Hybrid Angular.js (1.x) ↔ Angular interop.	upgrade
zone.js	Zone polyfill, shipped from this repo as a peer dependency.	zone-js
@angular/benchpress	Browser benchmarking harness.	benchpress

What's not a public package

The repo also has private and tooling packages that are not published:

• packages/private — internal utilities used by tests across packages (@angular/private/testing).
• packages/misc — miscellaneous internals.
• packages/examples — runnable code samples consumed by the docs pipeline.
• packages/docs — generated reference doc structure.
• tools/, scripts/ — build, release, and CI infrastructure.
• adev/shared-docs/ — shared components and the API generation pipeline used by angular.dev.

These appear in the workspace but are filtered out of the npm release pipeline.

zone.js is a peer of @angular/core rather than a transitive dependency. @angular/language-service is a TypeScript plugin consumed by editors, not by application code at runtime.

Where to start

If you've never opened the codebase, three packages are usually the right first stop:

1. core — the bulk of runtime behavior.
2. compiler-cli — how templates become Ivy instructions.
3. common — the directives and pipes most application code uses.
