Nodemon is an excellent tool for development, but you may occasionally run into errors. One such error is “Nodemon: Error: listen EADDRINUSE: address already in use :::5000” 

A number of things can cause this error, but fortunately, there is an easy fix. This article will explore the causes and solutions for this problem. Keep reading to find out now!

How Did “Nodemon: Error: listen EADDRINUSE: address already in use :::5000” Error Happen?

Nodemon is a great tool for development with Node.js, but it can sometimes be confusing why an error like “EADDRINUSE: address already in use :::5000” happens. This error can occur when running a Node.js project with nodemon and usually occurs when using port 5000.

The most probable reason for this error is that another process is already using port 5000 on your computer. 

Of course, this could be a different instance of Node.js or another application altogether. To fix this error, you’ll need to find out which process uses port 5000 and stop it. Let’s scroll down to learn how to do it.

4 Amazing Solutions To Fix This Issue

Solution 1

When you get the above error, it means that Nodemon cannot bind to port 5000 because that port is in use by another process. So you need to find and close the other process using that port to fix this. 

If you use VSC(Visual Studio Code), you should check your terminals by going to View > Integrated Terminal > Show in Explorer (or Command Palette > Toggle Integrated Terminal). This will show all of the terminals currently open on your system.

Solution 2

First, try increasing the –delay option (in milliseconds) passed to nodemon. This will give Node more time to start and free up the port. If that doesn’t work, you’ll need to stop your app manually with ctrl-c, then start it again with nodemon. 

Finally, if you’re using a process manager like PM2 or forever, make sure that nodemon is included in the startup script for your process manager.

Solution 3

You’re attempting to utilize the same port as another process on your system, which is the most typical source of this problem. You may either use a different port or use lsof to find out which method utilizes the port you want and then terminate that process to solve the problem.

Or you can use:
lsof -i tcp:3000 
sudo kill -9 $(lsof -i tcp: 3000 -t)

Solution 4

The last solution is to use the following commands:

  function () { 
    process.kill(, 'SIGUSR2'); 


In conclusion, there’re some tips to help solve the Nodemon: Error: listen EADDRINUSE: address already in use :::5000 issue. First, ensure that you’re not running any other programs using the same port. Second, check to see if another process is already using the port. 

Third, increase the port number if needed. Fourth, restart Nodemon. And finally, if all else fails, consult the Nodemon documentation or contact support. Thanks for reading!
