stumpart/stumpjs-compiler

Javascript compiler for ZF2

StumpJsCompiler

Version 0.0.1 Created by Barrington Henry, _(*1)

Introduction

Zend Framework 2 module that will combine and minify javascript files. Retrieves from cache on subsequent requests (Still in development), _(*2)

Installation

First, add the following line into your composer.json file:, _(*3)

"require": {
    "stumpart/stumpjs-compiler": "dev-master"
}

and then run, _(*4)

    php composer.phar update

Then, enable the module by adding StumpJsCompiler in your application.config.php file., _(*5)

<?php
return array(
    'modules' => array(
        'Application',
        'StumpJsCompiler',
    ),
);

Requirements

• Let the webserver user have write access to the application's data folder.
• Ensure that the Java Virtual Machine is installed on your web server. The compiler executables are jar files that will need this to execute

Configuration

The configurations need to get StumpjsCompiler up and running. This file is the module config file config/module.config.php, _(*6)

Definitions
cache-lifetime - The time in seconds that states how long the browser should cache the compiled javascript file
files          - The list of javascript files to include in the compilation
headers        - Additional headers that you may wish to send in the response. This will be added to the 
                 default list of headers.

```

## Usage

With this module installed and configured, using StumpjsCompiler in your view scripts is easy:
'compiledScript' is a view helper that will enable the user to enter a build name, eg. 'jstest1', which 
will then map to the 'jstest1' under 'builds' in the module.config.php file. 

```php
compiledScript('jstest1');?>

This view helper call can be placed anywhere in ur view script in the head or body tag., _(*7)
