Picker is an easy to use server side router for Meteor. This router respect others. So, you can use Iron Router and other routers and middlewares along side with this.

meteor add meteorhacks:picker

Picker.route('/post/:_id', function(params, req, res, next) {
  var post = Posts.findOne(params._id);
  res.end(post.content);
});

• You can use Meteor APIs inside this callback (runs inside a Fiber)
• Route definitions are very similar to Iron Router and Express
• req is an instance of NodeJS http.IncomingMessage
• res is an instance of NodeJS http.ServerResponse
• next is optional and call it, if you don't need to handle the current request

This is an unique functionality of this router. See following example:

Let's say we need to handle only POST requests. This is how you can do it with Picker.

var postRoutes = Picker.filter(function(req, res) {
  // you can write any logic you want.
  // but this callback does not run inside a fiber
  // at the end, you must return either true or false
  return req.method == "POST";
});

postRoutes.route('/post/:id', function(params, req, res, next) {
  // ...
});

You can create any amount of sub routes with this filter API. Same time, you can create nested sub routes as well.

You can use existing connect and express middlewares without any issues.

// You can use the meteorhacks:npm package to load in the body-parser package
// via NPM.
var bodyParser = Meteor.npmRequire( 'body-parser');

// Add two middleware calls. The first attempting to parse the request body as
// JSON data and the second as URL encoded data.
Picker.middleware( bodyParser.json() );
Picker.middleware( bodyParser.urlencoded( { extended: false } ) );

You can use middlewares on sub routes as well.
