Noder.io

Actual version published on NPM npm module downloads per month

Noder.io provides a lightweight and flexible core to create a scalable API of a lib, a module, an application or a framework. Noder.io is inspired (among others) by Angular and Pimple.

It is useful for starting a project quickly with a modular API ready to use.

Noder.io (and any object built on top of Noder.io) integrates:

No dependencies, works on Node.js and in the browser (only 7kb minified - 2kb gzipped).

Quick start

See quickstart.

Usage

Get common instance of Noder:

var noder = require('noder.io');

Best practice, create an instance of Noder class for your project:

// ./api/index.js
var Noder = require('noder.io').Noder;
var api   = new Noder();

// code body that constructs your API

module.exports = api;

or shortcut:

// ./api/index.js
module.exports = require('noder.io').createNoder();

Use your API in another file:

var api = require('./api');

// load a plugin
api.use('pluginName');

// create an item in the container
api.$di.set('someItem', 'value of the item');

// ...

Collection

Noder.io provides a class to handle a collection of items.

// create a collection
var items = noder.createCollection();

items.set('keyName', 'key value');

// keyName value
console.log(items.get('keyName'));

// get all items
var all = items.getAll();

// true
console.log(items instanceof noder.Collection);

See collection.

Dependency Injection

See dependency injection.

Lazy loading

noder.$require method provides a lazy require():

// define the property without loading the mongoose module
noder.$require('mongoose');

// false
console.log(noder.$require.isLoaded('mongoose'));

// lazy loading
var mongoose = noder.mongoose;

// true
console.log(noder.$require.isLoaded('mongoose'));

// true
console.log(noder.mongoose === require('mongoose'));

Aliases:

noder.$require('promise', 'bluebird');

// true
console.log(noder.promise === require('bluebird'));

Custom loader:

// factory: promisify the "fs" module
noder.$require('fs', function() {
  return noder.promise.promisifyAll(require('fs'));
});

fs.readFileAsync('./any-file.js')
  .then(function(contents) {
    console.log(contents);
  })
  .catch(function(err) {
    console.error(err);
  })
;

See lazy loading.

Plugins

Noder.io provides a plugin system to make a package works as a plugin for Noder.io and also as a standalone module or library.

Example of a Noder plugin:

/**
 * Initialization for use as a standalone module.
 * @return {Noder} New `Noder` instance
 */
module.exports = function blog() {

  var Noder = require('noder.io').Noder;
  var noder = new Noder();

  // or use the shortcut:
  // var noder = require('noder.io').createNoder();

  return module.exports.__noder(noder);
};

/**
 * Init `blog` plugin.
 * @param  {Noder} noder  `Noder` instance
 * @return {Noder}        Current `Noder` instance
 */
module.exports.__noder = function blogPlugin(noder) {

  // create config object only if not exists
  noder.$di.addOnce('config', {}, true);

  // sub-modules of blogPlugin
  // that add features to the instance of Noder
  noder.use(require('./api/article'));
  noder.use(require('./api/comment'));
  noder.use(require('./api/admin'));

  // Always return the instance of Noder to allow chaining
  return noder;
};

See plugins.

Unit Tests

Noder.io is fully tested with Unit.js and Mocha.
