proxy-pumpify

pipeline streams (combine) and also proxy non-stream methods. useful for advanced stream transforms like req and res.

Installation

1npm i --save proxy-pumpify

Usage

Example: transform a request

1require('http').createServer(function (req, res) {
2  // reverseStream reverses a stream
3  var reqTransform = pumpify(req, reverseStream())
4  // all methods and properties of request should work on reqTransform
5  var url = reqTransform.url
6  var headers = reqTransform.headers
7  // ...
8  // this will pipe the reversed req body to res
9  reqTransform.pipe(res)
10})

Example: transform a response

1var httpProxy = require('http-proxy')
2var proxy = httpProxy.createProxyServer();
3
4require('http').createServer(function (req, res) {
5  // reverseStream reverses a stream
6  // resTransform inherits from res: inherits takes 'src', 'dest', or any object to inherit from
7  const resTransform = pumpify(reverseStream(), res, { inherits: 'dest' })
8  // resTransform can be used in place of `res` w/ http-proxy, bc it inherits from `res`
9  // resTransform will reverse google's response body before piping it to res
10  proxy.web(req, resTransform, {
11    target: 'http://google.com'
12  })
13})
