This is a configuration file, likely for a JavaScript module loader like RequireJS. Let’s break down what it contains:
1. config Section:
* paths: This is the core of the configuration. It defines aliases (short names) for JavaScript files and libraries. this allows you to refer to thes files using the alias rather of the full path. Such as:
* "libs/velocity": "1.2.2" means that when you require("libs/velocity"), the module loader will load the file at version 1.2.2.
* "jquery": "libs/jquery/jquery-1.11.4" means that when you require("jquery"), it will load the jQuery library.
* The structure shows a lot of jQuery plugins and other libraries being loaded. The libs/ prefix suggests these are located in a libs directory within your project.
* shim: this section is crucial for dealing with libraries that don’t use the standard RequireJS module definition (e.g., libraries that just define global variables). shim tells RequireJS how to load these libraries and their dependencies.
* liveconnection/managers/connection: This module depends on liveconnection/libs/sockjs-0.3.4. It tells RequireJS to load sockjs-0.3.4 before liveconnection/managers/connection.
* liveconnection/libs/sockjs-0.3.4: this library exports a global variable named SockJS.
* libs/setValueFromArray and libs/getValueFromArray: These also export global variables named set and get respectively.
* fly/libs/backbone.marionette: This depends on jQuery, fly/libs/underscore, and fly/libs/backbone. It exports a global variable named Marionette.
* fly/libs/underscore-1.5.1: Exports a global variable named _.
* fly/libs/backbone-1.0.0: Depends on fly/libs/underscore and jQuery, and exports a global variable named Backbone.
* libs/jquery/ui/jquery.ui.tabs-1.11.4: This jQuery UI tab component depends on jQuery, the core jQuery UI components, and fly/libs/jquery.widget.
* libs/jquery/flexslider-2.1: Depends on jQuery.
* libs/dataTables.fixedColumns-3.0.4 and libs/dataTables.fixedHeader-2.1.2: Both depend on jQuery and DataTables.
* map: This section defines URL mappings. It’s used to resolve module names to specific URLs.
* adobe-pass: Maps the alias adobe-pass to a specific URL for Adobe Pass integration.
* facebook and facebook-debug: Maps the facebook alias to the facebook SDK URL.
In Summary:
This configuration file is designed to manage the dependencies of a JavaScript application. It tells RequireJS:
* Where to find various JavaScript libraries and modules.
* How to load libraries that don’t follow the standard module definition (using shim).
* How to resolve module names to URLs (using map).
Why is this useful?
* Dependency Management: It ensures that libraries are loaded in the correct order and that all dependencies are met.
* Organization: it provides a central place to manage all your JavaScript dependencies.
* Code Maintainability: It makes your code more modular and easier to maintain.
* Performance: RequireJS can optimize loading by only loading the modules that are actually needed.
