What is Angular CLI?
Angular CLI (Command Line Interface) is a powerful tool that simplifies the development process for Angular applications. With Angular CLI, you can easily create, configure, and maintain your projects using predefined commands. It ensures that your projects stay consistent, organized, and aligned with Angular’s best practices.
Prerequisites for Using Angular CLI
Before you start using Angular CLI, ensure the following tools are installed on your system:
| Tool | Command to Check Version | Purpose |
|---|---|---|
| Node.js | node --version | Runs Angular and other JavaScript tools |
| npm | npm --version | Manages packages, including Angular CLI |
If Node.js and npm aren’t installed, download them from the official Node.js website.
How to Create an Angular Application Using Angular CLI
Follow these 5 simple steps to set up your Angular project:
Step 1: Install Angular CLI
Install Angular CLI globally by running this command:
npm install -g @angular/cli
Step 2: Create a New Angular Project
Generate a new Angular project using the following command:
ng new myNewApp
The CLI will prompt you to choose configurations like style formats (CSS, SCSS, etc.).
Step 3: Navigate to Your Project Directory
Move into the newly created project folder using:
cd myNewApp
Step 4: Run the Development Server
Start your project locally with this command:
ng serve
Visit your app at http://localhost:4200/ in your browser.
