@ljharb/through

Note: This package is a fork of https://npmjs.com/through, and builds off of it.

Easy way to create a Stream that is both readable and writable.

Pass in optional write and end methods.
through takes care of pause/resume logic if you use this.queue(data) instead of this.emit('data', data).
Use this.pause() and this.resume() to manage flow.
Check this.paused to see current flow state. (write always returns !this.paused).

This function is the basis for most of the synchronous streams in event-stream.

1var through = require('@ljharb/through')
2
3through(function write(data) {
4    this.queue(data) //data *must* not be null
5  },
6  function end () { //optional
7    this.queue(null)
8  })

Or, can also be used without buffering on pause, use this.emit('data', data), and this.emit('end')

1var through = require('@ljharb/through')
2
3through(function write(data) {
4    this.emit('data', data)
5    //this.pause()
6  },
7  function end () { //optional
8    this.emit('end')
9  })

Extended Options

You will probably not need these 99% of the time.

autoDestroy=false

By default, through emits close when the writable and readable side of the stream has ended. If that is not desired, set autoDestroy=false.

1var through = require('@ljharb/through')
2
3//like this
4var ts = through(write, end, {autoDestroy: false})
5//or like this
6var ts = through(write, end)
7ts.autoDestroy = false
