UKRAINE NEEDS YOUR HELP NOW!

On 24 February 2022, Russian President Vladimir Putin ordered an invasion of Ukraine by Russian Armed Forces.

Your support is urgently needed.

• Donate to the volunteers. Here is the volunteer fund helping the Ukrainian army to provide all the necessary equipment: https://bank.gov.ua/en/news/all/natsionalniy-bank-vidkriv-spetsrahunok-dlya-zboru-koshtiv-na-potrebi-armiyi or https://savelife.in.ua/en/donate/
• Triple-check social media sources. Russian disinformation is attempting to coverup and distort the reality in Ukraine.
• Help Ukrainian refugees who are fleeing Russian attacks and shellings: https://www.globalcitizen.org/en/content/ways-to-help-ukraine-conflict/
• Put pressure on your political representatives to provide help to Ukraine.
• Believe in the Ukrainian people, they will not surrender, they don't have another Ukraine.

THANK YOU!

ShrinkWrap

Description

ShrinkWrap it's a wrapper for PHP minifiers of HTML/JS/CSS code. The main purpose of creating this wheel is the desire to have a more or less flexible tool for minifying ready-made HTML pages created by 3rd-party applications. Simply put - we submit an HTML page at the input, and at the output we have a page in which (optional):

• HTML, inline JS-scripts and CSS-styles are minified.
• JS and CSS files referenced by the page (except external ones) are minified (can also be combined) and cached, and the corresponding links are changed to point to the cache.

At the moment, ShrinkWrap uses the following tools:

• HTML DOM parser:
  • Masterminds/HTML5-PHP.
• Minifiers:
  • HTML:
    • voku/HtmlMin.
  • JS:
    • matthiasmullie/minify.
  • CSS:
    • matthiasmullie/minify.

Requirments

• PHP >= 7.3.0

Installation

Use composer: composer require fpvcode/shrinkwrap.
Due to dependency requirements the package loaded by default requires PHP version 8.1.0. To download the package compatible with PHP 7.3.0, create a composer.json file with the following content:

{
    "config": {
        "vendor-dir": "vendor",
        "platform": {
            "php": "7.3"
        }
    }
}

Usage

use fpvcode\ShrinkWrap;

$shrinkwrap = new ShrinkWrap();

// Global options
$shrinkwrap->doMinifyHtml(true);        // Allow to minify HTML Code. Default value is `false`.
$shrinkwrap->doMinifyInlineJs(true);    // Allow to minify inline scripts. The scripts combine and append in the bottom of related parent tag (`head` or `body`). Default value is `false`.
$shrinkwrap->doMinifyInlineCss(true);   // Allow to minify inline styles. The styles combine and append in the bottom of related parent tag (`head` or `body`). Default value is `false`.
$shrinkwrap->doMinifyJs(true);          // Allow to minify and cache non-minified JS-files. Default value is `false`.
$shrinkwrap->doCombineJs(true);         // Allow to combine all JS-files into one. Depends on `->doMinifyJS(true)`. Default value is `false`.
$shrinkwrap->doMinifyCss(true);         // Allow to minify and cache non-minified JS-files. Default value is `false`.
$shrinkwrap->doCombineCss(true);        // Allow to combine all CSS-files into one. Depends on `->doMinifyCSS(true)`. Default value is `false`.
$shrinkwrap->doLog(true);               // Show some info in the browser console. Default value is `false`.
$shrinkwrap->assetDir('assets');        // Directory to store minified files cache. Default value is `__DIR__/assets`.
