The TYPO3 core can compress CSS and JavaScript files to improve frontend-performance. Unlike CSS files the JavaScript files are only compressed with GZip and not minified. This extension integrates the popular library [JShrink](https://github.com/tedious/JShrink) to add this feature also for JavaScript.

This extension aims to be as lightweight as possible. Hopefully the minification will one day be integrated into the core to make this extension obsolete.

It is no replacement for much more powerful extensions like [Scriptmerger](https://typo3.org/extensions/repository/view/scriptmerger)!

Compatibility
-------------

[](#compatibility)

This extension uses a [XClass](https://wiki.typo3.org/XCLASS) to hijack the method `\TYPO3\CMS\Core\Resource\ResourceCompressor::compressJsFile()` and add the call to JShrink. This could break with every update of TYPO3, because this method is not defined as stable API. Please keep this in mind while your updating your instance.

If you have a better idea how JShrink could be integrated into the core, please drop me a line or create a pull request.

Currently supported versions: TYPO3 7.6.0 - 8.1.0 (newer versions should work, but are not tested yet)

Usage
-----

[](#usage)

Install the extension and make sure compression for JavaScript-files is [activated via Typoscript](https://docs.typo3.org/typo3cms/TyposcriptReference/Setup/Config/Index.html#compressjs):

```
page.config.compressJs = 1

```

Installing
----------

[](#installing)

### Composer

[](#composer)

Installing JShrink can be done through a variety of methods, although Composer is recommended.

```
"require": {
  "maximilian-walter/typo3-jshrink": "~1.0"
}

```

The JShrink-library will be automatically installed as dependency.

### TER

[](#ter)

This extension can also be installed via TER. You have to search for the name "jshrink". If you do so, please make sure the class `\JShrink\Minifier` can be used.
