method

Subprocess.send

send(
message: any
): void;

Send a message to the subprocess. This is only supported if the subprocess was created with the ipc option, and is another instance of bun.

Messages are serialized using the JSC serialize API, which allows for the same types that postMessage/structuredClone supports.
