EADDRINUSE Error

When you run your Medusa application you may run to an error similar to the following:

Terminal
❯code: 'EADDRINUSE',❯errno: -48,❯syscall: 'Listen',❯address: '::',❯port: 9000

This means that there's another process running at port 9000. You need to either:

• Change the default port used by the Medusa application. You can do that by setting the PORT environment variable to a new port. When you do this, make sure to change the port used in other apps that interact with your Medusa application, such as in your admin or storefront.
• Terminate other processes running on port 9000.
