Angular Get Started

To use Angular, you need npm which is included with Node.js.

Check Node.js

Angular's tooling (the CLI and build tools) runs on Node.js and uses npm to install packages.

Run these to confirm Node.js and npm are installed and on your PATH:

This prints your installed Node.js version, like:

Angular works best with the current LTS (Long Term Support) release (18 or 20).

If you get a "command not found" error, install Node.js (visit our Node.js tutorial for details).

You can also check npm:

npm is Node's package manager.

This prints your npm version, like:

npm should be automatically installed with Node.js.

Install Angular CLI

The Angular CLI is the official tool to create, build, and serve Angular apps.

The CLI (Command Line Interface) creates projects, runs a dev server, and provides helpful commands.

Install the Angular CLI globally:

Installing it globally makes the ng command available everywhere.

You can also use npx without a global install.

If you hit permission errors, use npx or run your terminal with elevated rights.

REMOVE ADS

Verify Angular CLI

Verify the installation to ensure ng is on your PATH and versions are compatible.

Displays the Angular CLI, Node.js, and Angular package versions so you can confirm the installation:

PATH is the list of folders your system searches for commands like ng.

Create an Angular Application

Create a project named my-angular-app:

This creates the project files and folders and installs dependencies.

It may take a few minutes and will ask a few prompts (see recommended choices below).

If you Use not to install the CLI globally, you can use npx:

Run the Angular Application

cd enters your new project folder.

ng serve starts a local dev server and watches for changes.

The first build can take a minute.

You can add the --open flag to automatically open the app in your default browser:

By default the dev server runs on http://localhost:4200.
