Reproxy

Reverse proxy for node.js applications.

Instalaltion

npm install reproxy

Access the the library like this:

var reproxy = require('reproxy');

Usage

Overview

To use reproxy you must implement your own reproxy adapter (or use existing ones). Reproxy doesn't come with any adapters, so this is will guide you for creating a simple one.

1. Creating a new adapter

var MyAdapter = Object.create(reproxy.Adapter);

1.1. Implement adapter's initialization method

MyArray.prototype.init = function() {
	console.log("Adapter is being initialized.");
};

1.2. Implement adapter's fetch method

MyAdapter.prototype.fetch = function() {
	return {
		"app1.vcap.me" : { host: 'localhost', port: 3000 },
		"app2.vcap.me" : { host: 'localhost', port: 3001 }
	};
};	

2. Running the proxy

// Creates the proxy using our adapter.
var proxy = new reproxy.Proxy(new MyAdapter());

2.1. Adding custom error handler

proxy.on('error', function(request, response, websocket) {
	response.writeHead(500);
	response.write("Cannot find routes for domain '" + request.headers.host + "'");
});

2.1. Adding transfer monitor

proxy.on('bandwidth', function(host, request, response) {
	console.log('Proxy status for ' + host);
	console.log('  Request:  ' + request + ' bytes.');
	console.log('  Response: ' + response + ' bytes.');
	console.log('');
});

2.2. Run the proxy

proxy.run(80);
