Node.js is an essential component for various open-source projects, often serving as a crucial dependency. When setting up a web server, it’s common to require Node.js. However, what if you want to develop and test your Node-dependent projects on your Windows PC before deploying them on a server? This tutorial will guide you through the process of installing Node.js on your Windows system and demonstrate how to run a Node.js app locally. Additionally, you’ll learn how to manage Node packages and uninstall Node.js when needed.
Node.js offers convenient installers for Windows, as well as binaries for Linux and macOS. While we’ll focus on Windows installation, the general process remains similar across different operating systems.
Step 1: Visit the Node.js Downloads Page Begin by navigating to the official Downloads page of Node.js (https://nodejs.org/en/download/). Here, you’ll find various installer options for Windows.
Step 2: Select the Installer Choose the installer that matches your system architecture. For this guide, we’ll use the 64-bit Windows Installer. Ensure you select the most appropriate version for your setup.
Step 3: Installation Completion After downloading the installer, run it to begin the installation process. Node.js and npm (Node Package Manager) will be installed on your system. You don’t need to separately install npm, as it comes bundled with Node.js.
Once Node.js is installed, you can proceed to run a Node.js app on your Windows PC. In this section, we’ll create a simple demonstration app.
Step 1: Create a Project Folder Start by creating a dedicated folder for your Node.js app. You can place it in a location that suits your organization, such as the Desktop. For example, you might create a folder named “projects” and then a subfolder called “my-node-app.”
Step 2: Writing Your Node.js App Within your project folder, you can write your Node.js application code. You can use any text editor or integrated development environment (IDE) of your choice. Write a basic Node.js application, or for demonstration purposes, you can use a modified version of Node’s web server example.
Step 3: Running Your Node.js App To run your Node.js app, open the Node.js command prompt, which you can access via the Windows Start menu. If you can’t locate it in the Start menu, simply type “node.js” in the search field to find it.
Step 4: Navigate to Your Project Folder Using the command-line interface (CLI), navigate to your Node.js project’s folder. For instance, if your project is located at “Desktop\projects\my-node-app,” use the “cd” (change directory) command as follows:
Step 5: Start Your Node.js App With the CLI in your project folder, you can execute your Node.js app. Simply run the appropriate Node.js command, depending on the filename of your Node.js application.
Node Package Manager (npm) simplifies the process of managing packages and dependencies for Node.js projects. Here’s how to use npm effectively.
Step 1: Create a package.json File Navigate to your project folder using the CLI and create a “package.json” file. This file will store information about your project and its dependencies.
Step 2: Installing Dependencies Use the following command to install project dependencies specified in your “package.json” file:
Step 3: Troubleshooting In case you encounter issues related to missing npm folders, follow these steps:
If you ever need to remove Node.js from your computer, follow these steps:
Step 1: Open Control Panel Go to “Start” and select “Control Panel.”
Step 2: Locate Node.js In the “Programs and Features” section, find “Node.js.”
Step 3: Uninstall Node.js Click on “Node.js” and then press the “Uninstall” button. Follow the prompts in the dialog window to complete the uninstallation process.
Conclusion Node.js is a vital tool for web developers, and installing it on your Windows PC is a straightforward process. Once installed, you can easily run Node.js applications locally, manage packages with npm, and, when necessary, uninstall Node.js. This guide has provided you with a comprehensive overview of these essential tasks, enabling you to harness the power of Node.js for your projects on Windows.
