Express Load

The express-load module provides the ability to load scripts into an Express instance from a specified directory. Make large express MVC applications easier to develop by allowing a logical file separation without having to include a bunch of files, see the examples folder for information.

Despite being a very simple module, it is extremely useful. It can be used to autoload models, routes, schemas, configs, controllers, object maps... etc...

express-load gives you access to the autoloaded files in the Express application instance to keep out of the global namespace. This also allows access to the scripts via the request object.

A script at ./controllers/user.js becomes available as app.controllers.user or req.app.controllers.user in a request.

Installation

$ npm install express-load

Usage

Multiple Directories

require('express-load')([
	'./models',
	'./controllers',
	'./routes'
], app);

Single Directory

require('express-load')('./routes', app);

The first parameter can be an array of directories or a string. The second parameter must be the Express application instance.

Example

app.js

var express = require('express')
  , load = require('express-load');

var app = express();

load(['./controllers', './routes'], app);

app.listen(3000)

If there were the following files in the controllers folder:

user.js post.js comment.js

They would then be available as: app.controllers.user app.controllers.post app.controllers.comment

Or from within a request as: req.app.controllers.user req.app.controllers.post req.app.controllers.comment

The directories are read synchronously, this is only done once when the app starts allowing the directories listed to have the scripts loaded in the order specified, for example you will want to load the controllers before the routes.

More examples will be available in the examples folder.
