Handle OS Signals

• Deno.addSignalListener() can be used to capture and monitor OS signals.
• can be used to stop watching the signal.

APIs for handling OS signals are modelled after already familiar and APIs.

⚠️ Note that listening for OS signals doesn’t prevent event loop from finishing, ie. if there are no more pending async operations the process will exit.

Run with:

You can use Deno.removeSignalListener() function to unregister previously added signal handler.

deno run signal_listeners.ts

If you prefer to handle signals using an async iterator, you can use API available in deno_std:

Run with:

deno run async_iterator_signal.ts
