Provides a way to load multiple modules into webservice at once


moduleLoader is a basic extension for webservice.js that provides an eased way to support multiple modules surfacing multiple methods as Web Services.

The basic syntax is as follows:

  modulesPath: '/api',
  title: "The long name of your product",
  name: "A short name",
  version: "0.1.0",
  endpoint: "http://localhost:8080"
var webservice  = require('webservice'),
    api         = require('./api'),
    colors      = require('colors');
console.log(' > stand-alone json webservice started on port 8080'.cyan);

At times it may be necessary for one module to call methods from another module. In this scenario the easiest way is to create a global api.js (or whatever name you want) that requires moduleLoader and returns it. An example of the api.js could be:

module.exports = require('moduleLoader')({
                    modulesPath: '/api',
                    title: "My REST Library",
                    name: "RLIB",
                    version: "0.1.0",
                    endpoint: "http://localhost:8080"

Then inside each module you would include the new api.js file within the calling method when you need to call a method from another module:

exports.echoProxy = function(options, callback){
  // Calls the echo method already defined in the API
  require('../api').echo(options, callback);
exports.echoProxy.schema = {
  msg: { 
    type: 'string',
    optional: false,
    message: "msg variable is required"
exports.echoProxy.description = 'This is a proxy wrapper around the API echo method.';

At the basic level moduleLoader scans the supplied folder for .js files and then requires them creating a temporary variable to hold the module.export that is returned. This temporary variable is then walked and used to expand on a local object. Finally, once all of the files have been loaded, this new object is returned.

Hopefully support for dynamic reloads will be added. This should also add in the functionality to load new modules when they are put into the watched directory.
