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. E.g.: + +<?php +// add /min/lib to your include_path first! +require $_SERVER['DOCUMENT_ROOT'] . '/min/utils.php'; + +$jsUri = Minify_groupUri('js'); +echo "<script type='text/javascript' src='{$jsUri}'></script>"; + + +DEBUG MODE + +In debug mode, instead of compressing files, Minify sends combined files with +comments prepended to each line to show the line number in the original source +file. To enable this, set $min_allowDebugFlag to true in config.php and append +"&debug=1" to your URIs. E.g. /min/?f=script1.js,script2.js&debug=1 + +Known issue: files with comment-like strings/regexps can cause problems in this mode. + + +QUESTIONS? + +http://groups.google.com/group/minify
