Unleash Your React JS Potential: How to Change Localhost Port

If you’re a developer working with React JS, you probably already know the importance of your localhost port. But did you know that you can easily change your localhost port when running your React JS application? This can be incredibly useful, especially when you are working on multiple projects or need to avoid port conflicts with other applications. In this #shorts article, we’ll show you how to change your localhost port for your React JS application.

Step 1: Open Your React JS Application

First, navigate to your React JS application in your code editor or terminal. Once you have your application open, you’ll need to locate the package.json file. This file contains various configurations for your React JS application, including the default localhost port.

Step 2: Edit the package.json File

Once you have located the package.json file, open it in your code editor. Look for the "scripts" section, where you will find the command to start your React JS application. By default, this command will typically be something like "start": "react-scripts start".

Under this command, you can add the --port flag followed by the desired port number. For example, you can change the command to "start": "react-scripts start --port 3001" to run your application on port 3001 instead of the default port.

Step 3: Save and Run Your Application

After making the necessary changes to the package.json file, save the file and close your code editor. Then, navigate to your terminal and run the command to start your React JS application. Your application will now run on the specified port, allowing you to unleash your React JS potential without worrying about port conflicts.

Changing your localhost port for your React JS application is a simple yet powerful way to optimize your development workflow. Whether you’re working on multiple projects or need to avoid port conflicts, knowing how to change your localhost port is a valuable skill for any React JS developer. With these steps, you can easily unleash your React JS potential and take your development to the next level.
