如果 Node.js 进程是从IPC频道派生出来的(具体看 Child Process 和  Cluster 的文档), process.disconnect()函数会关闭到父进程的IPC频道,以允许子进程一旦没有其他链接来保持活跃就优雅地关闭。


如果 Node.js 进程不是从IPC频道派生出来的,那调用process.disconnect()函数的结果是undefined.

If the Node.js process is spawned with an IPC channel (see the Child Process and Cluster documentation), the process.disconnect() method will close the IPC channel to the parent process, allowing the child process to exit gracefully once there are no other connections keeping it alive.

The effect of calling process.disconnect() is that same as calling the parent process's ChildProcess.disconnect().

If the Node.js process was not spawned with an IPC channel, process.disconnect() will be undefined.
