balboa

Simple, programmatic and hackable node.js HTTP forward proxy built-on-top of rocky.

Not designed for serious things, only for playground/development purposes.

Features

• Dead simple to set up
• Acts like a traditional HTTP forward proxy (e.g: Squid)
• Supports HTTP interceptors to modify request/response payloads
• Programmatically hackable (see rocky API)
• Command-line interface

Whish list

• Full HTTPS support (forward TLS peer certificate)

Installation

npm install -g balboa

For programmatic usage only install it in your dependency tree:

npm install balboa --save

Usage

Start the forward proxy:

balboa -p 8080

Then you can configure your web browser to use balboa as proxy (Firefox proxy settings below): <img src="http://i.imgur.com/eoC73LW.png" />

Finally, try browsing some site.

Programmatic API

Simple programmatic set up of an HTTP proxy to sniff and transform HTML metadata:

const balboa = require('balboa')
const proxy = balboa()

proxy
  .route
  .transformResponseBody(function (req, res, next) {
    if (/html/i.test(res.getHeader('content-type')) === false) return next()

    var body = res.body.toString()
    // Compose the new body
    var newBody = body.replace(/<body(.*)>/, '<body$1><h1>HELLO WORLD</h1>')
    // Set the modified body
    next(null, newBody, 'utf8')
  })

proxy.listen(8080)
console.log('Proxy server listening on port:', 8080)
