FAQPage Schema
How do I kill a Node.js process running on a specific port?

To kill a Node.js process running on a specific port, you can target it using the --port option. This selectively terminates the dev server occupying that port and resolves the conflict.

What is the best way to terminate all running development servers at once?

The best way to terminate all running development servers is to use the bulk termination command. This force-stops all Node.js processes and frees every port they occupy.

How can I check which ports are currently in use by dev servers?

You can check which ports are in use by running the command with the --check option. This reports the current status of all active development processes without terminating them.

Why does my dev server fail to start due to a port conflict?

Your dev server fails to start because a Node.js process is already bound to the required port. You must terminate the conflicting process or target a different port to start successfully.

Can I reset my development environment by force-stopping multiple Node.js processes?

Yes, you can reset your development environment by force-stopping multiple Node.js processes. This clears resource locks and frees all occupied ports simultaneously.
