Bouncy uses node's http parser innards to bounce http requests around to where they need to go in an entirely transparent way.
Use bouncy as a load balancer or http host router, either programmatically or with the simple command-line tool.
Bouncy is websocket-capable.
Bouncy 0.0.4 is faster than http-proxy 0.7.3 in this benchmark.
Route requests based on the host field
var bouncy = require('bouncy');
bouncy(function (req, bounce) {
if (req.headers.host === 'beep.example.com') {
bounce(8001);
}
else if (req.headers.host === 'boop.example.com') {
bounce(8002)
}
}).listen(8000);Just create a routes.json file like this:
{
"beep.example.com" : 8000,
"boop.example.com" : 8001
}Then point the bouncy command at this routes.json file and give it a port to
listen on:
bouncy routes.json 80
The routes.json file should just map host names to host/port combos.
Use a colon-separated string to specify a host and port in a route.
Use "" for the host as a default route.
bouncy(cb) returns a new net.Server object that you can .listen() on.
Your callback cb will get these arguments:
The node http module request object.
Call this function when you're ready to bounce the request to a stream.
The exact request that was received will be written to stream and future
incoming data will be piped to and from it.
You can specify header fields to insert into the request with opts.headers.
By default, "x-forwarded-for", "x-forwarded-port", and "x-forwarded-proto"
are all automatically inserted into the outgoing header.
These variants of bounce() are sugar for
bounce(net.createConnection(port))
and
bounce(net.createConnection(port, host)).
Optionally you can pass port and host keys to opts and it does the same thing.
Return a new HTTP response object for the request. This is useful if you need to write an error result.
With npm, do:
npm install bouncy
to install as a library or
npm install -g bouncy
to get the command-line tool.
