Web developers often need to run a development server on their PC and test it on a mobile device within the same network. This tutorial ensures seamless localhost access on mobile devices, guiding you step-by-step through testing across devices.
Step 1: Find your computer's local IP address
Step 2: Ensure your localhost server is running
Step 3: Modify your firewall Settings if Needed for proper access to localhost in the same network
Step 4: Access localhost on your mobile or tablet
Step 5: Troubleshooting Common Issues
Issue: The Page Doesn't Load on Mobile
Check both devices are connected to the same network.
Recheck the IP address and port running on your computer.
Verify the firewall settings on your computer.
Issue: Server Not Responding
Confirm the server is running on your computer and can access the application on your computer first.
First, check if another application blocks the port.
Issue: Connection Refused
Ensure your server is configured to listen to external requests. For example: For Node.js: Use 0.0.0.0 instead of localhost in your app's server setup.
One of the most effective and simple ways to test your online applications in real-world situations is to access your localhost application from a mobile device connected to the same network. This configuration guarantees a smooth end-user experience by enabling developers to test responsive designs, user interactions, and performance directly on mobile browsers.
