The SitePoint PHP blog has posted a tutorial showing you how to optimize how your application works with assets with Munee.
Munee is a n asset management tool which can compile LESS, SCSS, or CoffeeScript, manipulate images, minify CSS and JS, and cache assets on the server and client on the fly. It works with PHP 5.3 and newer versions.In this tutorial, we will learn how Munee makes it easy to include assets in templates, how to install it, how it works and how to use it. Munee is another way to avoid NodeJS in asset management of PHP apps.
He starts the article with a few reasons why you'd want to use Munee to manage your application's assets including automatic minification and both server and client side cache handling. He covers a bit about how it works and what it does to cache assets via simple HTTP headers. He then gets into the actual installation of the tool, the code needed to run it in your system (a one-line call) and how to have the server rewrite all the requests back to the waiting PHP file. He shows how to compile different asset types including SCSS, LESS and CoffeScript files as well as minifying Javascript and CSS. Munee also includes an on-the-fly image resize handler that will also cache the results. Finally he talks about how you can use it to combine assets and briefly about the API the library provides for some other functionality.
