js-minify

A fast Javascript minifier that removes unnecessary whitespace and comments

Installation

If you are using Composer, use

composer require garfix/js-minify

Use

The simplest use of the library comes down to this:

$minifiedJs = \Garfix\JsMinify\Minifier::minify($js);

Where $js contains the unprocessed code and $minifiedJs holds the minified version.

If you want to change the default options, use minify($js, $options), where $options is an array of one or more of the following:

• \Garfix\JsMinify\Minifier::FLAGGED_COMMENTS (bool, default: true) When set to false, /*! ... */ flagged comments are removed as well.

Background

I started this library because I believed JShrink could be made much faster by the use of dedicated regular expressions. This turned out to be true. It is about 10x faster on PHP 7 and 5x faster on PHP 8.
