It combines multiple CSS or Javascript files, removes unnecessary whitespace and comments, and serves them with gzip encoding and optimal client-side cache headers 4.0.2(3mo ago)3.0k17.8M—0.2%468[58 issues](https://github.com/mrclay/minify/issues)20BSD-3-ClausePHPPHP ^8.1CI passing Since Jul 20Pushed 3mo ago144 watchersCompare [ Source](https://github.com/mrclay/minify)[ Packagist](https://packagist.org/packages/mrclay/minify)[ Docs](https://github.com/mrclay/minify)[ RSS](/packages/mrclay-minify/feed)WikiDiscussions master Synced 1mo ago READMEChangelog (10)Dependencies (11)Versions (30)Used By (20) Minify is no longer regularly maintained ---------------------------------------- [](#minify-is-no-longer-regularly-maintained) The original authors no longer recommend using Minify, especially previous versions, which were not designed to handle modern JS and CSS syntax. Instead, use an up-to-date performance measurement tool like [Lighthouse](https://developer.chrome.com/docs/lighthouse/overview) and follow its recommendations. In 2010, Minify offered a fine improvement for some websites, but browsers and HTTP servers are now much better, and Minify may offer only a marginal performance benefit in narrow cases. Also both JS and CSS now change rapidly, and new syntaxes are likely to lead to broken code being served through Minify. About ----- [](#about) Minify is an HTTP server for JS and CSS assets. It compresses and combines files and serves it with appropriate headers, allowing conditional GET or long-Expires. *Before*[![7 requests](https://camo.githubusercontent.com/15daabdd2cfd2aa9bceb73e11cf9ef628994c49418e25ed7f16e3de312621155/687474703a2f2f6d72636c61792e6f72672f77702d636f6e74656e742f75706c6f6164732f323030382f30392f666964646c65725f6265666f72652e706e67)](https://camo.githubusercontent.com/15daabdd2cfd2aa9bceb73e11cf9ef628994c49418e25ed7f16e3de312621155/687474703a2f2f6d72636c61792e6f72672f77702d636f6e74656e742f75706c6f6164732f323030382f30392f666964646c65725f6265666f72652e706e67)*After*[![2 requests](https://camo.githubusercontent.com/b9c1aa5259ec2986b36f0abaada3829c1ac4de705616121576260aca25646cfa/687474703a2f2f6d72636c61792e6f72672f77702d636f6e74656e742f75706c6f6164732f323030382f30392f666964646c65725f61667465722e706e67)](https://camo.githubusercontent.com/b9c1aa5259ec2986b36f0abaada3829c1ac4de705616121576260aca25646cfa/687474703a2f2f6d72636c61792e6f72672f77702d636f6e74656e742f75706c6f6164732f323030382f30392f666964646c65725f61667465722e706e67)The stats above are from a [brief walkthrough](http://mrclay.org/index.php/2008/09/19/minify-21-on-mrclayorg/) which shows how easy it is to set up Minify on an existing site. It eliminated 5 HTTP requests and reduced JS/CSS bandwidth by 70%. Relative URLs in CSS files are rewritten to compensate for being served from a different directory. Static file serving ------------------- [](#static-file-serving) Version 3 allows [serving files directly from the filesystem](static/README.md) for much better performance. We encourage you to try this feature. Support ------- [](#support) Post to the [Google Group](http://groups.google.com/group/minify). Installation ------------ [](#installation) See the [install guide](docs/Install.wiki.md). Configuration & Usage ------------------------- [](#configuration--usage) (Using 2.x? [Here are the 2.x docs](https://github.com/mrclay/minify/tree/2.x/docs).) See the [user guide](docs/UserGuide.wiki.md). Minify also comes with a [URI Builder application](docs/BuilderApp.wiki.md) that can help you write URLs for use with Minify or configure groups of files. See the [cookbook](docs/CookBook.wiki.md) for more advanced options for minification. More [docs are available](docs). Unit Testing ------------ [](#unit-testing) 1. Install dev deps via Composer: `composer install` 2. `composer test` or `phpunit` Warnings -------- [](#warnings) - Minify is designed for efficiency, but, for very high traffic sites, it will probably serve files slower than your HTTPd due to the CGI overhead of PHP. See the [FAQ](docs/FAQ.wiki.md#how-fast-is-it) and [CookBook](docs/CookBook.wiki.md) for more info. - If you combine a lot of CSS, watch out for [IE's 4096 selectors-per-file limit](http://stackoverflow.com/a/9906889/3779), affects IE 6 through 9. - Minify *should* work fine with files encoded in UTF-8 or other 8-bit encodings like ISO 8859/Windows-1252. By default Minify appends ";charset=utf-8" to the Content-Type headers it sends. Acknowledgments --------------- [](#acknowledgments) Minify was inspired by [jscsscomp](http://code.google.com/p/jscsscomp/) by Maxim Martynyuk and by the article [Supercharged JavaScript](http://www.hunlock.com/blogs/Supercharged_Javascript) by Patrick Hunlock. The [JSMin library](http://www.crockford.com/javascript/jsmin.html) used for JavaScript minification was originally written by Douglas Crockford and was [ported to PHP](https://github.com/mrclay/jsmin-php) by Ryan Grove specifically for use in Minify. ### Health Score 76 — ExcellentBetter than 100% of packages Maintenance82 Actively maintained with recent releases Popularity76 Solid adoption and visibility Community54 Growing community involvement Maturity83 Battle-tested with a long release history Bus Factor1 Top contributor holds 59.1% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
