Changing the port number in a Vue CLI project is a common need for developers working on multiple projects simultaneously or facing conflicts with existing services. Luckily, Vue CLI provides a straightforward way to adjust the port number to suit your specific requirements. In this guide, we will walk through the steps to change the port number in your Vue CLI project effortlessly.
Firstly, locate the "vue.config.js" file in the root directory of your Vue project. If you don't have this file yet, create it in the same directory as your "package.json" file. The "vue.config.js" file allows you to configure various aspects of your Vue project, including the development server settings.
Next, open the "vue.config.js" file with your preferred code editor. If you're using Visual Studio Code, you can simply right-click on the file and choose to open it with the editor. Inside the "vue.config.js" file, you need to add the following configuration snippet to change the port number:
module.exports = {
devServer: {
port: 3000, // Change this to your desired port number
}
};In this code snippet, we are setting the port number to 3000 as an example. You can replace this value with any other port number you prefer. Save the changes to the file once you've updated the port number.
After saving the changes, stop your Vue development server if it's currently running. You can do this by pressing "Ctrl + C" in the terminal window where the server is running. Once the server stops, restart it by running the "npm run serve" command in the terminal.
When the development server restarts, it will now be running on the new port number you specified in the "vue.config.js" file. You can access your Vue application by navigating to http://localhost:YOUR_NEW_PORT_NUMBER in your web browser, replacing "YOUR_NEW_PORT_NUMBER" with the port number you set.
By following these steps, you have successfully changed the port number for your Vue CLI project. This simple adjustment can help you avoid conflicts and streamline your development workflow when working on multiple projects simultaneously.
In conclusion, knowing how to change the port number in your Vue CLI project is a valuable skill for any Vue.js developer. With the flexibility offered by Vue CLI's configuration options, you can easily tailor the development environment to meet your specific needs. Whether you're debugging an issue or simply customizing your setup, being able to adjust the port number gives you greater control over your Vue projects.
