# mitm-stream

creates a connected replacement for an original duplex stream and gives access to two transforms to intercept messages

# usage

`npm install mitm-stream`

```js

var through2 = require('through2')

var duplexify = require('duplexify')

var opts = { objectMode: true }

var in$  = through2(opts, function (chunk, encoding, next) { this.push(chunk); next() })

var out$ = through2(opts, function (chunk, encoding, next) { this.push(chunk); next() })

var remoteOriginal = duplexify(in$, out$, opts)

remoteOriginal.write('ping')

remoteOriginal.on('data', function (data) { console.log('O',data) })

//----------------------------------------------------------

// GIVEN:

var original = duplexify(out$, in$, opts)

var mitm = require('./')

var replacement = mitm(original, function (original2replacement, replacement2original) {

  original2replacement._transform = function (chunk, encoding, next) {

    next(null, chunk.toUpperCase())

  }

  original2replacement.on('data', function (data) { // data from original

    console.log(`[MITM] ${data} [from original]`)

  })

  original2replacement.write('pingpong [BY MITM]')  // data to replacement

  replacement2original._transform = function (chunk, encoding, next) {

    next(null, chunk.toUpperCase())

  }

  replacement2original.on('data', function (data) { // data from replacement

    console.log(`[MITM] ${data} [from replacement]`)

  })

  replacement2original.write('pongping [BY MITM]')  // data to original

})

replacement.write('pong')

replacement.on('data', function (data) { console.log('R',data) })
