NAME Apache2::Filter::Minifier::JavaScript - JavaScript minifying output filter for mod_perl SYNOPSIS PerlOutputFilterHandler Apache2::Filter::Minifier::JavaScript # if you need to supplement MIME-Type list PerlSetVar JsMimeType text/json # if you want to explicitly specify the minifier to use #PerlSetVar JsMinifier JavaScript::Minifier::XS #PerlSetVar JsMinifier JavaScript::Minifier #PerlSetVar JsMinifier MY::Minifier::function DESCRIPTION Apache2::Filter::Minifier::JavaScript is a Mod_perl2 output filter which minifies JavaScript using JavaScript::Minifier or JavaScript::Minifier::XS. Only JavaScript documents are minified, all others are passed through unaltered. Apache2::Filter::Minifier::JavaScript comes with a list of several known acceptable MIME-Types for JavaScript documents, but you can supplement that list yourself by setting the JsMimeType PerlVar appropriately (use PerlSetVar for a single new MIME-Type, or PerlAddVar when you want to add multiple MIME-Types). Given a choice, using JavaScript::Minifier::XS is preferred over JavaScript::Minifier, but we'll use whichever one you've got available. If you want to explicitly specify which minifier you want to use, set the JsMinifier PerlVar to the name of the package/function that implements the minifier. Minification functions are expected to accept a single parameter (the JavaScript to be minified) and to return the minified JavaScript on completion. If you specify a package name, we look for a minify() function in that package. Caching Minification does require additional CPU resources, and it is recommended that you use some sort of cache in order to keep this to a minimum. Being that you're already running Apache2, though, here's some examples of a mod_cache setup: Disk Cache # Cache root directory CacheRoot /path/to/your/disk/cache # Enable cache for "/js/" location CacheEnable disk /js/ Memory Cache # Cache size: 4 MBytes MCacheSize 4096 # Min object size: 128 Bytes MCacheMinObjectSize 128 # Max object size: 512 KBytes MCacheMaxObjectSize 524288 # Enable cache for "/js/" location CacheEnable mem /js/ METHODS handler($filter) JavaScript minification output filter.
