BaseOptions.onDisconnect method | Bun module

Called exactly once when the IPC channel between the parent and this subprocess is closed. After this runs, no further IPC messages will be delivered.

When it fires:

The child called process.disconnect() or the parent called subprocess.disconnect().The child exited for any reason (normal exit or due to a signal like SIGILL, SIGKILL, etc.).The child replaced itself with a program that does not support Bun IPC.

Notes:

This callback indicates that the pipe is closed; it is not an error by itself. Use onExit or Subprocess.exited to determine why the process ended.It may occur before or after onExit depending on timing; do not rely on ordering. Typically, if you or the child call disconnect() first, this fires before onExit; if the process exits without an explicit disconnect, either may happen first.Only runs when ipc is enabled and runs at most once per subprocess.If the child becomes a zombie (exited but not yet reaped), the IPC is already closed, and this callback will fire (or may already have fired).

const subprocess = spawn({
cmd: ["echo", "hello"],
ipc: (message) => console.log(message),
onDisconnect: () => {
console.log("IPC channel disconnected");
},
});
