magento-rjs-config

NOTE This readme is deprecated. See https://devdocs.magento.com/guides/v2.3/performance-best-practices/advanced-js-bundling.html

NOTE Configuration generation tool that automates build.js creation was created by Shane Osbourne: https://github.com/WeareJH/config-gen

This r.js build file is built for Magento 2.2.0-rc30 CE Luma theme.

NOTE: Manual modification of the build.js file for your project IS NOT REQUIRED. A major benefit will be achieved by any Magento/blank or Magento/luma-based installation with this build configuration without the need for any modifications. Tweaking the build.js file is optional if you want to achieve 100% improvements.

The Magento 2 built-in bundler relies only on PHP, which is not very efficient and could lead to potential issues. The build file build.js from this repository can be used to execute bundling and minification on deployed static content with the r.js tool shipped with the NPM version of RequireJS. It will optimize the main pages of Magento 2.

The process described here should be applied only during deployment to production.

Usage

Install r.js
Download build.js from this repo
Edit build.js to remove/add files from your custom theme to bundles (optional)
Apply the jquery.cookie issue patch
Run magento setup:static-content:deploy to deploy Magento 2 static content to {magentoDir}/pub/static/ folder
For every theme locale that you use:
- Move {magentoDir}/pub/static/{area}/{vendor}/{theme}/{locale} folder to {magentoDIr}pub/static/{area}/{vendor}/{theme}/{locale}_source
- Run r.js -o build.js baseUrl={magentoDir}/pub/static/{area}/{vendor}/{theme}/{locale}_source dir={magentoDir}/pub/static/{area}/{vendor}/{theme}/{locale}

Output

Bundles all files common for all Magento 2 Luma storefront pages into requirejs/require.js file
Generates 5 page-specific bundle files:
- bundles/default.js - should be added to default layout handle
- bundles/cart.js - should be added to checkout_cart_index layout handle
- bundles/checkout.js - should be added to checkout_index_index layout handle
- bundles/catalog.js - should be added to catalog_category_view and catalog_product_view layout handles
- bundles/product.js - should be added to catalog_product_view layout handle

Adding bundles to pages

To add a bundle file to the corresponding page, add following instruction to the page layout update file in your module:

  <head>
    <script src="bundles/{bundleFile}.js" />
  </head>

Example for cart pages, create a file My/Module/view/frontend/layout/checkout_cart_index.xml with the following contents:

<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
    <head>
        <script src="bundles/cart.js" />
    </head>
</page>

Fixing missconfiguration of jquery.cookie

JQuery.cookie module should be added to 'deps'. To add, create a 'requiejs-config.js' file in your module:

//My/Module/view/frontend/requirejs-config.js
var config = {
    'deps': ['jquery/jquery.cookie']
};
