How to Install Node JS for Angular Development

Installing Node.js is the first step in setting up an Angular development environment. This JavaScript runtime allows you to run JavaScript code on the server, making it essential for building dynamic web applications with Angular. In this guide, we will walk you through the process of installing Node.js and configuring your system for Angular development.

To get started, download Node.js from the official website ('node js install angular'). The installation process is straightforward, and once complete, you can verify that Node.js is installed by opening a command prompt or terminal and running `node -v` to check the version of Node.js installed on your computer.

Once Node.js is installed, the next step is to install the Angular CLI (Command Line Interface), which is a powerful tool that makes it easy to create, manage, and build Angular projects. To install the Angular CLI, open a command prompt or terminal and run `npm install -g @angular/cli`. This will install the Angular CLI globally on your computer.

With Node.js and the Angular CLI installed, you can now create a new Angular project by running the following command: `ng new my-app`. Replace 'my-app' with the name of your project. This will create a new Angular project called 'my-app' in a new directory.

After creating a new project, you can start the development server and run your application. To do this, navigate to your project folder and run `ng serve`. By default, the development server will watch your files for changes and automatically reload the page when changes are detected.

You can also open your application in a web browser by navigating to `http://localhost:4200`. You should see the default Angular welcome page. This makes it easy to develop and test your application in real-time.

In conclusion, installing Node.js is an essential step in setting up an Angular development environment. With Node.js installed, you can install the Angular CLI and create new Angular projects using the `ng new` command. Once a project is created, you can start the development server and run your application by navigating to `http://localhost:4200`.
