Learn Angular

Build large, structured web apps with TypeScript.

Angular is a full front-end framework maintained by Google for building single-page applications in TypeScript. Unlike lighter libraries, it ships with routing, forms, an HTTP client, testing setup and a command-line tool out of the box, which makes it popular in large companies and enterprise teams. You build with components, share logic through injectable services, and manage reactive state with signals and RxJS observables. Modern Angular uses standalone components and template control flow like @if and @for. Note that AngularJS is an older, separate framework. Learnr builds a personalized Angular course and teaches it through short lessons.

How to learn Angular, step by step

Get comfortable with TypeScript first. Angular code is TypeScript everywhere, with classes, decorators, interfaces and generics. A week or two on types and classes saves you from confusing framework errors with language errors.
Create a project with the Angular CLI. Install the CLI, run ng new and ng serve, then generate a component with ng generate component. Read the generated files so you know where templates, styles and tests live.
Learn templates, bindings and signals. Practice interpolation, property binding, event binding and @if and @for blocks. Hold component state in signals and derive values with computed so the view updates without manual work.
Move logic into services with dependency injection. Create an injectable service that fetches data with HttpClient and inject it into components. This separation is central to how real Angular apps stay maintainable.
Add routing and reactive forms. Build a small app with a list page, a detail route with a parameter and a reactive form with validators. Show validation messages and disable submit until the form is valid.
Learn enough RxJS and test your code. Understand observables, subscribe, pipe and operators like map, switchMap and debounceTime for a search box. Write a component test, and keep the many Angular terms fresh with brief Learnr lessons.

What's inside your Angular course

A sample path Learnr builds for Angular. Your real course adapts to your goal and level.

1. TypeScript refresher and the Angular CLI
2. Components, templates and data binding
3. Signals, inputs and outputs
4. Services, dependency injection and HttpClient
5. Routing and reactive forms
6. RxJS, testing and building for production

How long does it take to learn Angular?

With JavaScript and some TypeScript, expect 1 to 2 months at 6 to 8 hours a week to build a working CRUD app, and 3 to 6 months to feel productive on a team codebase with RxJS and testing.

What you need before you start

Solid HTML, CSS and JavaScript, plus basic TypeScript. Familiarity with classes and asynchronous code helps, since services and HTTP calls rely on both.

Common mistakes to avoid

Following AngularJS tutorials by mistake. AngularJS (version 1) is a different, retired framework, so make sure resources cover modern Angular.
Putting HTTP calls and business logic directly in components. Move them into services so components stay small and testable.
Subscribing to observables manually and never unsubscribing, which leaks memory. Use the async pipe, toSignal or takeUntilDestroyed instead.

Angular questions, answered

Is Angular harder than React?

Angular has more concepts up front, like dependency injection and RxJS, because it is a complete framework. In exchange, many decisions about routing, forms and structure are already made for you.

Do I need to learn RxJS for Angular?

You need the basics, because HttpClient and many Angular APIs return observables. Signals now cover much of the simple state handling, so deep RxJS can come later.
