property
An AbortSignal that can be used to abort the subprocess.
This is useful for aborting a subprocess when some other part of the program is aborted, such as a fetch response.
If the signal is aborted, the process will be killed with the signal specified by killSignal (defaults to SIGTERM).
const controller = new AbortController();
const { signal } = controller;
const start = performance.now();
const subprocess = Bun.spawn({
cmd: ["sleep", "100"],
signal,
});
await Bun.sleep(1);
controller.abort();
await subprocess.exited;
const end = performance.now();
console.log(end - start); // 1ms instead of 101ms
