![]() The first conditional comemnt allows only non-IE and IE8+ browsers to fetch the stylesheet. In order to only load the relevant stylesheet to supporting browsers, and preventing doubling the effective payload of the background images, you would reference the stylesheets like this: Now, in order to create the two versions of the stylesheet, you would simply run Juicer with and without the option to embed images $ juicer merge master.css -o -embed-images data_uri It could look like this: /* master.css url(typography.css) To do this, you would have a master stylesheet that imports the other stylesheets using the statemet. In order to be as unobtrusive as possible, you must indicate for each image that it can be embedded in the stylesheet by using the embed url suffix.Įxample: h1 Īnd let’s assume that you want to merge these, and embed the flagged images in layout.css into the stylesheet. Juicer supports embedding images into stylesheets using data uri’s. Hard cache busters result in URLs such as:, ie URLs that require either renaming of files, or (more conveniently) a web server configuration that will forward URLs to the right files anyway. For this reason Juicer provides hard cache busters. Unfortunately, the popular web proxy Squid shipped for some time with a default configuration which would not treat a URL as a “new” URL if the only thing changed was the GET parameters. ![]() This mimics the behavior of the image_tag helper in the Ruby on Rails framework, so that images called from both CSS and from Rails views will have identical URLs. Rails cache busters are similar, except they leave out the parameter name. Soft cache busters (the default) add a parameter to the URL, like so: assets/images/1.png?jcb=1234567890, ie the letters “jcb” (as in Juicer Cache Buster) and then the timestamp of the files mtime. A cache buster is a pattern in a path whose only purpose is to “trick” browsers to redownload a file when it has changed in cases where a far future expires header is used. You can also use -absolute-urls to convert all URLs to absolute ones. Juicer automatically recalculates referenced URLs to reflect this change.Ībsolute URLs are not changed by default, but if you provide juicer merge with -document-root and -relative-urls then absolute URLs are converted to URLs relative to output directory. You may also want the resulting CSS file to end up in another directory as well. When merging CSS files, you may want to merge CSS files in different directories. You can use (CSS files) and (JavaScript) recursively, effectively creating a dependency chain for Juicer to climb and merge. Running juicer merge on this file will result in a minified file containing the file jquery-1.4.1.js (located in the same directory) and the code above. Juicer can treat your JavaScript files much the same way too, parsing a comment switch as this example shows: /** Eventually it will support other minifying tools too. This file may be minified using the YUI Compressor or Google Closure Compiler. Juicer can read statements in CSS files and use them to combine all your stylesheets into a single file. Recalculate relative URLs in CSS files, as well as convert them to absolute (or convert absolute URLs to relative URLs)Įmbed images into stylesheets using data-uris Verify that your JavaScript is safe to minify/compress by running JsLint on it Use YUI Compressor or Google Closure Compiler to compress code, thus improving performance Juicer is a command line tool that helps you ship frontend code for production.įigure out which files depend on each other and merge them together, reducing the number of http requests per page view, thus improving performance Opt for a Philips juicer to get all the all-important nutrients from your fruit or vegetable, leaving the unwanted pulp behind.Official URL: /cjohansen/juicer/tree/master And, if you do it yourself, not only is it super fresh, but it will also save you a lot of money down the road.
