How to Install and Setup Node.js
Welcome to our guide on how to install and set up Node.js on your computer. Node.js is a popular runtime environment that allows you to run JavaScript on the server-side, making it a valuable tool for web development. In this article, we will walk you through the steps to get Node.js up and running on your system.
Step 1: Download Node.js
The first step in installing Node.js is to download the latest version from the official Node.js website. You can visit nodejs.org and click on the “Download” button to get the installer for your operating system.
Step 2: Install Node.js
Once the download is complete, run the installer and follow the on-screen instructions to install Node.js on your computer. The installer will guide you through the setup process and install Node.js along with npm, which is the Node package manager.
Step 3: Verify Installation
To verify that Node.js has been installed correctly, open a terminal or command prompt and type node -v. This command will display the version of Node.js that is installed on your system. You can also run npm -v to check the version of npm.
Step 4: Write Your First Node.js Script
Now that Node.js is installed, you can start writing your first Node.js script. Create a new file with a .js extension, write some JavaScript code, and save the file. To run the script, open a terminal or command prompt, navigate to the directory where the file is saved, and type node filename.js.
Step 5: Install Node.js Packages
One of the most powerful features of Node.js is its package management system. You can use npm to install packages that extend the functionality of Node.js and streamline your development workflow. To install a package, use the command npm install package-name.
Step 6: Set Up a Node.js Project
To set up a new Node.js project, create a new directory for your project, navigate to the directory in the terminal or command prompt, and run the command npm init. This will initialize a new Node.js project and create a package.json file.
Step 7: Start Your Node.js Server
Once you have set up your Node.js project, you can start your Node.js server by running the command node server.js. This will start the server and allow you to access your application through a web browser.
