To set up a development environment for Angular, you need to install Node.js, npm (Node Package Manager), and the Angular CLI. Below are the steps to accomplish this on various operating systems:
Node.js and npm Installation
Windows
Download Node.js Installer:
Visit the Node.js download page.
Download the recommended version for most users (LTS).
Install Node.js:
Run the installer.
Follow the prompts in the installer, accepting the default settings.
The installer will also install npm, which is bundled with Node.js.
Verify Installation:
Open Command Prompt (cmd).
Run the following commands to verify the installations:
node -v
npm -v
These commands should output the installed versions of Node.js and npm.
macOS
Download Node.js Installer:
Visit the Node.js download page.
Download the recommended version for most users (LTS).

Angular CLI Installation
Once Node.js and npm are installed, you can install the Angular CLI.
Install Angular CLI Globally:
Open your command line interface (Command Prompt, Terminal, etc.).
Run the following command:
npm install -g @angular/cli
Verify Angular CLI Installation:
Run the following command to verify the installation:
ng --version
This command should output the installed version of the Angular CLI.
Creating a New Angular Project
Create a New Angular Project:
Navigate to the directory where you want to create your project.
Run the following command:
ng new my-angular-app
Follow the prompts to set up your new Angular project.
Navigate to Project Directory:
cd my-angular-app
Serve the Application:
Run the following command to serve your application:
ng serve
Open a web browser and navigate to http://localhost:4200 to see your application running.
With these steps, you should have a fully set-up development environment for Angular.
