# Welcome to Minify!
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](http://mrclay.org/wp-content/uploads/2008/09/fiddler_before.png) |
|----------|-----------------------------------------------------------------|
| *After* | ![2 requests](http://mrclay.org/wp-content/uploads/2008/09/fiddler_after.png) |
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
Version 3 allows [serving files directly from the filesystem](static/README.md) for much better performance. We encourage you to try this feature.
## Support
Post to the [Google Group](http://groups.google.com/group/minify).
## Installation
See the [install guide](docs/Install.wiki.md).
## 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
1. Install dev deps via Composer: `composer install`
1. `composer test` or `phpunit`
## 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
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.
