Caronte is an HTTP programmable proxying library that supports websockets. It is suitable for implementing components such as proxies and load balancers.
A new proxy is created by calling createProxyServer and passing
an options object as argument (valid properties are available here)
var caronte = require('caronte');
var proxy = caronte.createProxyServer(options);An object will be returned with four values:
- web
req, res, [options](used for proxying regular HTTP(S) requests) - ws
req, socket, head, [options](used for proxying WS(S) requests) - ee (an EventEmitter2 that emits events, you can hook into them to customize behaviour)
- listen
port(a function that wraps the object in a webserver, for your convenience)
Is it then possible to proxy requests by calling these functions
require('http').createServer(function(req, res) {
proxy.web(req, res, { target: 'http://mytarget.com:8080' });
});When a request is proxied it follows two different pipelines (available here)
which apply transformations to both the req and res object.
The first pipeline (ingoing) is responsible for the creation and manipulation of the stream that connects your client to the target.
The second pipeline (outgoing) is responsible for the creation and manipulation of the stream that, from your target, returns data
to the client.
You can easily add a pass (stages) into both the pipelines (XXX: ADD API).
In addition, every stage emits a corresponding event so introspection during the process is always available.
