Angular is a framework for building web applications, developed by Google and written in TypeScript, that ships the whole set in one opinionated package: components, routing, forms, HTTP client, dependency injection and a build toolchain. It is common in large corporate and internal applications, where a team values one prescribed way of doing everything over freedom of choice.

Angular is a framework for building web applications, developed by Google and written in TypeScript, that ships the whole set in one opinionated package: components, routing, forms, HTTP client, dependency injection and a build toolchain. It is common in large corporate and internal applications, where a team values one prescribed way of doing everything over freedom of choice.

Work happens through its command-line tool, the Angular CLI (ng), installed with npm. ng new scaffolds a project, ng serve runs a development server, and ng build compiles the TypeScript and templates into optimised bundles of HTML, CSS and JavaScript. Node.js is needed to develop and build; the result runs in the browser, so a built Angular app is static files a host can serve.

By default an Angular app is an SPA rendered on the client (CSR): the browser receives a small shell and the bundle builds the page. Angular also supports SSR and prerendering when the first paint or crawlability matter.

Its contrast with React is the classic one. React is a library for the view layer and leaves routing, state and data fetching to other packages; Angular decides all of them, which costs a steeper start and buys large teams a codebase where every module looks alike.

Versions move together. The CLI, the framework packages, TypeScript and RxJS (its library for streams of events) have compatible ranges, and ng version lists them; an upgrade is done with ng update, step by step across major versions.

React hands you a set of excellent tools; Angular hands you the workshop, with the benches already bolted to the floor.

Angular is distinct from AngularJS, its 2010 predecessor in plain JavaScript, which shares little beyond the name. Where it sits among the other frameworks is in framework.
