ModeraMJRCacheAwareClassLoaderBundle

This bundles enables browser caching mechanism for MJR application, so once page is loaded then all scripts will be permanently cached in client's browser and further page loads will not require any pre-cached scripts to be loaded again. Shortly speaking, this is how this bundle works - it adjusts Ext.Loader class that is used to dynamically load your scripts so it would append so called version number and when bundle is configured it will be suffixing all loaded script files with that version and in conjunction with properly configured web-server ( apache/nginx instructions provided ) next time page is loaded pre-cached scripts will be used.

Installation

Step 1: Download the Bundle

composer require modera/mjr-cache-aware-class-loader:4.x-dev

This command requires you to have Composer installed globally, as explained in the installation chapter of the Composer documentation.

Step 2: Enable the Bundle

This bundle should be automatically enabled by Flex. In case you don't use Flex, you'll need to manually enable the bundle by adding the following line in the config/bundles.php file of your project:

<?php
// config/bundles.php

return [
    // ...
    Modera\MJRCacheAwareClassLoaderBundle\ModeraMJRCacheAwareClassLoaderBundle::class => ['all' => true],
];

Optionally you may specify a version number using bundle's semantic config, to do this you need to add this to your config file:

// config/packages/modera.yaml

modera_mjr_cache_aware_class_loader:
    version: "1.5.0"

Apache2

To instruct client's browser that it should use cache we will need to have mod_expires apache module installed. On Debian like system this can be done by issuing these commands:

sudo a2enmod expires
sudo service apache2 restart

Once the module is enabled you can take Resources/server/.htaccess file shipped with this bundle and put it to your web directory. Feel free to tweak provided .htaccess, since the only real thing that you need from it is <IfModule mod_expires.c> section. If caching still doesn't work make sure that support for .htaccess files is enabled (check your virtual hosts definition in /etc/apache2/sites-enabled/ directory or if you don't use virtual hosts then take a look at /etc/apache2/apache2.conf, please make sure that configuration property AllowOverride is set to All in <Directory> configuration section).

Nginx

Update your virtual host ( default location on Debian-like system is /etc/nginx/sites-enabled ) and to your server configuration section add this:

location ~*\.js\?v=$ {
    expires 1y;
}

And then restart nginx:

sudo service restart nginx

Documentation

Bundle provides several configuration properties that you can use to adjust it better for your needs, for more information please see \Modera\MJRCacheAwareClassLoaderBundle\DependencyInjection\Configuration.
