How to disable debugging with a signal in nodejs?

We can start debugger in nodejs using kill -USR1 PID. How can we disable it using any signal or any other way without terminating the worker?

While SIGUSR1 is used to start the debug inspector (equivalent to running node with the --inspect flag), you can customize SIGUSR2 to close the inspector without killing the process.

Adding something like this to your main app should add that behavior.

const inspector = require('inspector');

process.on('SIGUSR2', () => {
    console.log('Received SIGUSR2. Closing inspector.');
    inspector.close();
});
