This app will combine and minify your Javascript or -CSS files and serve them with HTTP compression and cache headers. - - -RECOMMENDED - -It's recommended to edit config.php to set $min_cachePath to a writeable -(by PHP) directory on your system. This will improve performance. - - -GETTING STARTED - -The quickest way to get started is to use the Minify URI Builder application -on your website: http://example.com/min/builder/ - - -MINIFYING A SINGLE FILE - -Let's say you want to serve this file: - http://example.com/wp-content/themes/default/default.css - -Here's the "Minify URL" for this file: - http://example.com/min/?f=wp-content/themes/default/default.css - -In other words, the "f" argument is set to the file path from root without the -initial "/". As CSS files may contain relative URIs, Minify will automatically -"fix" these by rewriting them as root relative. - - -COMBINING MULTIPLE FILES IN ONE DOWNLOAD - -Separate the paths given to "f" with commas. - -Let's say you have CSS files at these URLs: - http://example.com/scripts/jquery-1.2.6.js - http://example.com/scripts/site.js - -You can combine these files through Minify by requesting this URL: - http://example.com/min/?f=scripts/jquery-1.2.6.js,scripts/site.js - - -SIMPLIFYING URLS WITH A BASE PATH - -If you're combining files that share the same ancestor directory, you can use -the "b" argument to set the base directory for the "f" argument. Do not include -the leading or trailing "/" characters. - -E.g., the following URLs will serve the exact same content: - http://example.com/min/?f=scripts/jquery-1.2.6.js,scripts/site.js,scripts/home.js - http://example.com/min/?b=scripts&f=jquery-1.2.6.js,site.js,home.js - - -MINIFY URLS IN HTML - -In (X)HTML files, don't forget to replace any "&" characters with "&". - - -SPECIFYING ALLOWED DIRECTORIES - -By default, Minify will serve any *.css/*.js files within the DOCUMENT_ROOT. If -you'd prefer to limit Minify's access to certain directories, set the -$min_serveOptions['minApp']['allowDirs'] array in config.php. E.g. to limit -to the /js and /themes/default directories, use: - -$min_serveOptions['minApp']['allowDirs'] = array('//js', '//themes/default'); - - -GROUPS: FASTER PERFORMANCE AND BETTER URLS - -For the best performance, edit groupsConfig.php to pre-specify groups of files -to be combined under preset keys. E.g., here's an example configuration in -groupsConfig.php: - -return array( - 'js' => array('//js/Class.js', '//js/email.js') -); - -This pre-selects the following files to be combined under the key "js": - http://example.com/js/Class.js - http://example.com/js/email.js - -You can now serve these files with this simple URL: - http://example.com/min/?g=js - - -GROUPS: SPECIFYING FILES OUTSIDE THE DOC_ROOT - -In the groupsConfig.php array, the "//" in the file paths is a shortcut for -the DOCUMENT_ROOT, but you can also specify paths from the root of the filesystem -or relative to the DOC_ROOT: - -return array( - 'js' => array( - '//js/file.js' // file within DOC_ROOT - ,'//../file.js' // file in parent directory of DOC_ROOT - ,'C:/Users/Steve/file.js' // file anywhere on filesystem - ) -); - - -FAR-FUTURE EXPIRES HEADERS - -Minify can send far-future (one year) Expires headers. To enable this you must -add a number to the querystring (e.g. /min/?g=js&1234 or /min/f=file.js&1234) -and alter it whenever a source file is changed. If you have a build process you -can use a build/source control revision number. - -If you serve files as a group, you can use the utility function Minify_groupUri() -to get a "versioned" Minify URI for use in your HTML.

To enable this, set $min_allowDebugFlag to true in config.php and append -"&debug=1" to your URIs.
