What is Angular CLI: Overview and Usage Explained

Angular CLI is a command-line tool that helps developers create, build, and manage Angular projects easily. It automates tasks like project setup, code generation, and running development servers, making Angular development faster and simpler.

⚙️

How It Works

Think of Angular CLI as a helpful assistant that knows all the steps to build an Angular app. Instead of doing everything by hand, like creating files and setting up configurations, you just tell the CLI what you want, and it does the work for you.

It uses commands typed in your terminal to generate code, run your app in a browser, and prepare your app for sharing with others. This saves time and avoids mistakes, much like using a recipe instead of guessing how to cook a new dish.

💻

Example

This example shows how to create a new Angular project and start a development server using Angular CLI.

bash

npm install -g @angular/cli
ng new my-app
cd my-app
ng serve

Output

✔ Packages installed successfully. ** Angular Live Development Server is listening on localhost:4200, open your browser on http://localhost:4200/ **

🎯

When to Use

Use Angular CLI whenever you start a new Angular project or want to add features like components, services, or routing quickly. It is perfect for beginners to avoid setup confusion and for experienced developers to speed up repetitive tasks.

In real life, if you want to build a website or app with Angular, the CLI helps you focus on writing your app’s logic instead of worrying about setup details.
