node app listen change ip

Step 1: Import the required modules In order to change the IP address that a Node.js app listens on, we need to first import the necessary modules. This can be done using the require keyword followed by the name of the module. For example, to import the express module, we would use const express = require('express');.

Step 2: Create an instance of the app Next, we need to create an instance of the app using the imported module. This can be done by calling the module as a function and storing the result in a variable. For example, const app = express();.

Step 3: Set the IP address and port To change the IP address that the app listens on, we need to specify the IP address and port number in the listen method of the app instance. The IP address can be specified using the second parameter of the listen method. For example, app.listen(3000, '192.168.0.1'); will make the app listen on IP address 192.168.0.1 and port 3000.

Step 4: Start the server Finally, we need to start the server by calling the listen method of the app instance. This will make the app listen for incoming requests on the specified IP address and port. For example, app.listen(3000, '192.168.0.1'); will start the server and make it listen on IP address 192.168.0.1 and port 3000.

That's it! By following these steps, you can change the IP address that a Node.js app listens on. Remember to replace the IP address and port number with your desired values.
