amd-manager

Notes for Meteor 0.9.x

This package is now called amd:manager.

meteor-amd-manager

This package provides AMDManager class that allows you to implement your own define/require module management routines.

Installation

Simply type

meteor add amd:manager

and you're good to go.

Usage

As an example, lets implement the standard define/reqire pair. This could be done more like this:

var manager = new AMDManager(),
 
require = function (listOrName, body) {
  var readyDep, isReady;
  if (_.isFunction(body)) {
    if (!_.isArray(listOrName)) {
      listOrName = [listOrName, ];
    }
    return manager.require(listOrName, body);
  } if (_.isString(listOrName)) {
    return manager.get(listOrName);
  }
  throw new Error('Wrong parameters for require.');
}
 
define = function (name, deps, body) {
  if (arguments.length == 2) {
    body = deps; deps = [];
  }
  manager.define(name, deps, body);
}
 
define.amd = {};

Methods

The only non-obvious methods of the manager are:

• onModuleNotFound which allows you to define a callback to be called every time should the user request a module that has not been defined yet. You can use it to decide if there is a need to download additional source code from the server.
• onModuleAlreadyDefined which is called when a module is trying to be defined with the same name as an already defined module. You can use it to display a warning or throw an error.
