Introduction
In this tutorial we learn how to install libjs-requirejs on Ubuntu.
What is libjs-requirejs
libjs-requirejs is:
RequireJS loads plain JavaScript files as well as more defined modules. It is optimized for in-browser use, including in a Web Worker, but it can be used in other JavaScript environments, like Rhino and Node. It implements the Asynchronous Module API
RequireJS uses plain script tags to load modules/files, so it should allow for easy debugging. It can be used simply to load existing JavaScript files, so you can add it to your existing project without having to re-write your JavaScript files.
RequireJS includes an optimization tool you can run as part of your packaging steps for deploying your code. The optimization tool can combine and minify your JavaScript files to allow for better performance.
If the JavaScript file defines a JavaScript module via define(), then there are other benefits RequireJS can offer: improvements over traditional CommonJS modules and loading multiple versions of a module in a page. RequireJS also has a plugin system that supports features like i18n string bundles, and text file dependencies.
RequireJS does not have any dependencies on a JavaScript framework.
The standard require.js file is around 5.5KB when minified via Closure Compiler and gzipped.
RequireJS works in IE 6+, Firefox 2+, Safari 3.2+, Chrome 3+, and Opera 10+.
This package also provides a script r.js, that has two major functions:
- Run AMD-based projects in Node and Rhino.
- Includes the RequireJS Optimizer that combines scripts for optimal browser delivery.
