+# PHP JSStrip
+
+This is a PHP port of Nick Galbreath's python tool [jsstrip.py](https://code.google.com/p/jsstrip/).
+
+It was originally ported to PHP in 2006 as part of the [DokuWiki](http://www.dokuwiki.org) wiki engine. It has received several improvements over the years and is now available as a standalone library.
+
+Quoting the original description:
+
+jsstrip is a open-source library to remove whitespace and comments from a javascript file. You might want to do this to optimize size and performance, or to make a file harder to read. It typically makes 30-40% savings in file size.
+
+**WARNING**
+
+jsstrip is not a true javascript parser. It assumes you have properly delimited the 'end of line' using a ';' (semicolon).
+
+  * Yes `print 'foo'; print 'bar';`
+  * No `print 'foo' print 'bar'`
+
+You'll have to convert your code to use ';' first.
+
+ALWAYS test the stripped version before deploying to production.
+
+
+## Installation
+
+Install via composer
+
+    composer require splitbrain/php-jsstrip
+
+## Usage
+
+```php
+<?php
+
+require_once 'vendor/autoload.php';
+
+$js = file_get_contents('somefile.js'); // gather your JS here somehow
+
+$minifiedJS = (new \splitbrain\JSStrip\JSStrip())->compress($js);
+```
+
+## Skip Minification
+
+You can skip Minification for parts of your code by surrounding it by special comments:
+
+```js
+/* BEGIN NOCOMPRESS */
+const foo = 'No compression here'; // this comment will also stay
+/* END NOCOMPRESS */
+```
