ref
Calling subprocess.ref()
after making a call to subprocess.unref()
will restore the removed reference count for the child process, forcing the parent to wait for the child to exit before exiting itself.
const { spawn } = require('node:child_process');
const subprocess = spawn(process.argv[0], ['child_program.js'], {
detached: true,
stdio: 'ignore',
});
subprocess.unref();
subprocess.ref();
