pseudo

pseudo is a utility module which aims to improve maintenance of large express.js projects splitting actions and middlewares(filters) into different directories.

Example Project Structure

- app.js
- actions
   home.js
   dashboard.js
- filters
   requireLogin.js
   requireAdmin.js

How it works

Let's setup you need a route as GET / that requires the user to be logged in.

The express.js way

Using only express.js you will have do to something similar to this:

app.js

// ... Load your app.
function requireLogin(req, res, next) {
    // validate the user
    next();
};

app.get('/',requireLogin, function(req, res) {
   // render some view for the home page
});
// Start the server

Of course you can use module.exports and split the middleware but it requires some extra work.

The pseudo way

Using pseudo loader you will have your middlewares into the filters directory and the actions in a directory with the same name:

app.js

// ... Load your app.
require('pseudo').init({Application:app,customContext:"This is my custom context stuff!"});
// Start the server

actions/home.js

var pseudo = require('pseudo')
pseudo.get('/', {
    filters:['requireLogin'],
        action:function(req, res) {
            var greeting = this.customContext // use custom context bound values
            // render some view for the home page
    }
});

filters/requireLogin.js

module.exports.filter = function(req, res, next) {
    // validate the user
    var greeting = this.customContext  // use custom context bound values
    next();
}

Download

You can install it using Node Package Manager (npm):
