Creating a Node.js stream from two piped streams

Question

I\'d like to combine two Node.js streams into one by piping them, if possible. I\'m using Transform streams.

In other words, I\'d like my library to return myS

Answer 1

One option is perhaps to use multipipe which lets you chain multiple transforms together, wrapped as a single transform stream:

// my-stream.js
var multipipe = require('multipipe');

module.exports = function createMyStream() {
  return multipipe(vendorStream, myInternalStream);
};

Then you can do:

var createMyStream = require('./my-stream');

var myStream = createMyStream();

process.stdin.pipe(myStream).pipe(process.stdout);

Clarification: This makes stdin go through vendorStream, then myInternalStream and finally stdout.
