v0.0.8

An extremely minimal router. Seriously, it's pretty much just an EventEmitter (but that's a good thing.) It's the router you'd write if you were writing a router.

Add to your project with npm install ramrod --add and include it in your node app. It's meant to be used with the http module. Here's what it looks like in action:

var http = require('http');
var ramrod = require('ramrod');
var router = ramrod();

router.add('my/:route', function(req, res, param ){
  res.writeHead(200);
  res.end('Hello '+ param +'\n');
});

router.add('foo/:bar', function(req, res, param, querystring ){
  res.writeHead(200);
  res.end('Hello '+ param +'\n');
});

router.on('*', function(req, res){
  res.writeHead(200);
  res.end('All other urls go here :)\n');
});

http.createServer(function(req, res){
  router.dispatch(req, res);
}).listen(3000);

Returns a Ramrod instance and takes an optional routes object as its only argument.

The routes object takes the form:

{
  'route/:param1/:param2': function( req, res, p1, p2 ){
    // route handler
  },

  'namedRegExpRoute': /^custom\/(reg|ex)/,

  'route/:param': null
}

Routes can be processed as route/handler pairs, named Regular Expression routes, or a route directive with a null value.

Route strings can contain :params and *splats that are passed to the route's callback when matched.

Named routes can be useful for aliasing a complex route string. If the name is present, the route will be given that event name. E.g.:

router.add('foo/:bar', 'foo'); // router will emit a 'foo' event

If a funtion is passed as the last argument, it will be used as the handler for the route being added. The callback is always passed the http.ClientRequest and http.ClientResponse objects as its first 2 arguments.

router.on('foo', function( req, res ){ ... });

Adds a route handler that will only be triggered when req.method === GET

Adds a route handler that will only be triggered when req.method === POST

Adds a route handler that will only be triggered when req.method === PUT

Adds a route handler that will only be triggered when req.method === DELETE

Inhereted from EventEmitter

Callbacks recieve all the same arguments as when attached with add.

Processes a request and a response object, emitting the first matched route from the ramrod.routes object. A before event is emitted prior to matching against the route table. If no matching routes are found, the '*' event is emitted.
