Understanding the Error

The "Listen EADDRINUSE :::5000" error occurs when an application attempts to bind to a port that is already in use by another process. This can happen if you have multiple instances of your application running or if another application is using the same port.

Step-By-Step Solution

Step 1: Identify the Process Using the Port

First, you need to identify the process that is using the port in question. You can do this by running the following command in your terminal:

For Linux and macOS:

sudo lsof -i :5000

For Windows:

netstat -ano | findstr :5000

The output will display the process ID (PID) of the application using the port.

Step 2: Terminate the Process

Once you have identified the process using the port, you can terminate it using the following command:

For Linux and macOS:

sudo kill <PID>

For Windows:

taskkill /F /PID <PID>

Replace <PID> with the process ID you found in step 1.

Step 3: Restart Your Application

Now that you have terminated the conflicting process, you can restart your application, and it should bind to the port without any issues.


Q1: Can I change the port my application is using?

Yes, you can change the port your application is using to resolve the EADDRINUSE error. To do this, locate the configuration file or code in your application where the port is defined and change the value to an unused port number.

Q2: How do I find an available port?

You can use the netstat command to check for available ports. For example, run netstat -tuln on Linux and macOS or netstat -a on Windows to display a list of currently used ports.

Q3: Can I run multiple instances of my application on the same port?

No, you cannot run multiple instances of your application on the same port. Each instance must bind to a unique port.

Q4: Is it possible to resolve the EADDRINUSE error without terminating the conflicting process?

This depends on the conflicting process. If it is another instance of your application or an application you can modify, you can change its configuration to use a different port. If not, you must terminate the conflicting process to free up the port.

Q5: Is there a way to prevent the EADDRINUSE error in the future?

To prevent this error in the future, ensure that you are not running multiple instances of your application on the same port, and double-check that no other applications are using the port your application is configured to use.
