Class ProcessPidFile

Class to manage a PID file for the current process.

This class provides methods to write the current process PID to a specified file and to remove the PID file when it is no longer needed.

Note: The PID file is automatically removed when the process exits, if it was created by this class instance.

Example usage:

const pidFile = new ProcessPidFile("/var/run/myapp.pid");
await pidFile.write();
// ... application logic ...
await pidFile.remove();
