README

This Symfony2 bundle allows you to minify html code, combine and minify JavaScript files and CSS files without Java VM.

Installation

Install using composer.json

If you are using composer to manage your project, just add the following line to your composer.json file

{
    "require": {
    	"sema/minifier-bundle": "dev-master"
    }
}

Then update the vendor libraries:

composer.phar update
# OR
composer.phar update sema/minifier-bundle # to only update the bundle

Register the bundle

You must register the bundle in your kernel:

<?php

// app/AppKernel.php
public function registerBundles()
{
    $bundles = array(
        // ...
        new Sema\Bundle\MinifierBundle\SemaMinifierBundle(),
    );
    // ...
}

#Use

You have two options for minify html:

onKernelResponse listener
Twig Extension

Enable minify html using onKernelResponse listener

You need add follow lines in config.yml

    #app/config.yml
    sema_minifier:
        enable_listener: true

All responses will be minified

Enable minify html using Twig Extension

You need modify base template (base.html.twig or layout.html.twig or something else), add {% minifyhtml %} to the top of the file and {% endminifyhtml %} to the bottom of the file. You need get something like this

    #base.html.twig
    {% minifyhtml %}
    <!DOCTYPE html>
    <html>
        <head>
            <meta charset="UTF-8" />
            <title>{% block title %}Welcome!{% endblock %}</title>
            {% block stylesheets %}{% endblock %}
            <link rel="icon" type="image/x-icon" href="{{ asset('favicon.ico') }}" />
        </head>
        <body>
            {% block body %}{% endblock %}
            {% block javascripts %}{% endblock %}
        </body>
    </html>
    {% endminifyhtml %}

##Use combine and minify js or css files The configuration file is a JSON file that describes all the rules for combining static files. Each group is assigned a file name to which we refer in the templates. This allows you to not get attached to the physical location of the file, which can be handy when you change the file structure. Below is a sample configuration file assets.json

{
    "css": {
        "main": {
            "output": "assets/css/dist/main.min.css",
            "input": [
                "bundles/framework/css/structure.css",
                "bundles/framework/css/body.css"
            ]
        }
    },
    "js": {
        "vendor": {
            "output": "assets/js/dist/vendor.min.js",
            "input": [
                "assets/libs/jquery/dist/jquery.js"
            ]
        },
        "html5shiv": {
            "output": "assets/js/dist/html5shiv.min.js",
            "input": "assets/libs/html5shiv/dist/html5shiv.js"
        },
        "form": {
            "output": "assets/js/dist/form.min.js",
            "input": [
                "assets/libs/parsleyjs/dist/parsley.js",
                "assets/libs/jquery-ui/jquery-ui.js",
                "assets/js/form.js"
            ]
        }
    }
}

Depending on the debug mode expansion will transmit a pattern or an array of source files, or an array of processed files. Here is an example template:

<!DOCTYPE html>
<html>
    <head>
        <meta charset="utf-8" />
        <title>{% block title %}Welcome!{% endblock %}</title>
        {% block stylesheets %}
          {% for url in assets.css['main'] %}
              <link rel="stylesheet" href="{{ asset(url) }}" />
          {% endfor %}
        {% endblock %}
        <!--[if lt IE 9]>
            <script src="{{ asset(assets.js['html5shiv'][0], version='1') }}"></script>
        <![endif]-->
        <link rel="icon" type="image/x-icon" href="{{ asset('favicon.ico') }}" />
    </head>
    <body>
        {% block body %}{% endblock %}
        {% block javascripts %}
          {% for url in assets.js['vendor'] %}
              <script src="{{ asset(url) }}"></script>
          {% endfor %}
        {% endblock %}
    </body>
</html>
