Angular.dev

Signals let you track state changes and update the interface only where it matters, instead of re-checking the whole page. Angular graduated its core signal APIs to stable, so this is now the standard way to manage data and reactivity in an app. The payoff shows up as smoother updates and less code spent on manual change tracking.

Zoneless mode runs an app without zone.js in the bundle, which trims overhead and makes debugging clearer. It became stable in Angular v20.2 and is now the default direction for new projects. The result is a smaller package and behavior that is easier to reason about.

Templates support @if, @for, and @switch blocks, plus @defer for loading parts of a page only when a user needs them. This replaced the older structural directives and cut the cost of rendering large lists. Deferred blocks also drive incremental hydration, so a page can become interactive piece by piece.

Angular can render pages on the server, then reuse the existing DOM in the browser instead of rebuilding it. The team reports consistent gains in Core Web Vitals, including faster Largest Contentful Paint, on real apps. This matters if search ranking and first-load speed carry weight for your site.

Angular.dev devotes a whole section to adding AI to an app, covering Genkit, Firebase AI Logic, and the Gemini API with starter kits and example repos. It also ships an MCP server with tools like get_best_practices and find_examples for AI coding assistants. Developers get a documented path instead of figuring out integrations alone.

A single command-line tool handles project creation, code generation, testing, and production builds. The build pipeline runs on Vite and esbuild, and ng update automates version migrations. Vitest is the default test runner as of Angular v21.
