wikimedia/minify

Minify is a PHP library for minification of JavaScript code and CSS stylesheets.

Quick start

Install using Composer, from Packagist.org:

composer require wikimedia/minify

Usage

$input = '
function sum(a, b) {
// Add it up!
return a + b;
}
';
$output = JavaScriptMinifier::minify( $input );
// Result:
// function sum(a,b){return a+b;}
$input = '
.foo,
.bar {
/* comment */
prop: value;
}
';
$output = CSSMin::minify( $input );
// Result:
// .foo,.bar{prop:value}

Known limitations

The following trade-offs were made for improved runtime performance and code simplicity. If they cause problems in real-world applications without trivial workarounds, please let us know!

  • T37492: In CSS, content within quoted strings that looks like source code are sometimes minified.
  • T287631: In CSS, writing a URL over multiple lines with escaped line-breaks is not supported.
