Use pump with a Transform Stream as final stream object

Using pump like this;

pump.apply null, [
  tcpSocket
  transformStream
  writableStream
  handleEndFn
]

will call the handleEndFn just fine when the TCP socket breaks / closes.

Now, due to the way the destroyer passes its arguments (based on the stream object position) to the end-of-stream module, the following

pump.apply null, [
  tcpSocket
  transformStream
  transformStream
  handleEndFn
]

will not trigger the handleEndFn function (allowHalfOpen defaults to true).

What would be the handest way to circumfence the obliged applcation of pump, but now using a Transform Stream as the last stream object in the pipeline?

Ah yes. Thanks a lot for explaining!

new Writable objectMode: true, write: (c, e, cb) -> cb()

By calling the cb right away you never hit backpressure yes
