Connect Dynamic Middleware

Allow to change the middleware dynamically in a running connect/express application.

Example

Let's imagine you have this simplistic express server:

var express = require('express');
var application = express();
application.use(express.cookieParser('this is the secret!'));
application.get('/',function(req,res) {
  res.send(200, 'Hello !');
});
application.listen(6666);

Now let's imagine you want to modify the secret associated with the cookie parser middleware. Of course, you don't want to restart your server... Just use the dynamic connect middleware :

var express = require('express');
var cdm = require('connect-dynamic-middleware');
var application = express();
var cookieMiddleware = cdm(express.cookieParser('this is the secret!'));
application.use(cookieMiddleware);
application.get('/',function(req,res) {
  res.send(200, 'Hello !');
});
application.put('/cookieSecret/:secret', function(req,res) {
  var newSecret = req.params.secret;
  cookieMiddleware.setMiddleware(express.cookieParser(newSecret));
  res.send(200, 'OK');
});
application.listen(6666);

Tests

Use the command:

grunt

to launch the test suite. For it to work, you'll need gjslint, and a Mongodb server listening on localhost:27017.
