to-through v3.0.0

to-through

Wrap a Readable stream in a Transform stream.

Usage

var { Readable } = require('streamx');
var concat = require('concat-stream');
var toThrough = require('to-through');

var readable = Readable.from([' ', 'hello', ' ', 'world']);

// Can be used as a Readable or Transform
var maybeTransform = toThrough(readable);

Readable.from(['hi', ' ', 'there', ','])
  .pipe(maybeTransform)
  .pipe(
    concat(function (result) {
      // result === 'hi there, hello world'
    })
  );

API

toThrough(readableStream)

Takes a Readable stream as the only argument and returns a Transform stream wrapper. Any data piped into the Transform stream is piped passed along before any data from the wrapped Readable is injected into the stream.
