How should a developer restart a server after making file changes?

After changing any server file, a developer must restart the server immediately. This ensures the new code is active. Multiple server instances can cause old code to run, leading to errors.

The rule

After changing any server file, a developer must restart the server immediately.

This ensures the new code is active. Multiple server instances can cause old code to run, leading to errors.

A developer must restart the server after any file change. This makes sure the new code is used. The developer should stop the server by its port number. The developer must check that the port is free. Then, the developer starts the server again. Only one server instance should be running.

A developer changes a server file to fix a bug. The developer restarts the server by its process name instead of its port. This leaves an old server instance running. Most users still experience the bug because the old code is serving their requests.

How can a developer be sure the server is showing the correct version of a file after an edit?

A developer edits a file. The developer then needs to check if the server is actually using that new file.
