README

A simple plugin allowing to handle Webpack generated CSS and Javascript assets within Craft CMS templates.

Requirements

This plugin requires Craft CMS 3.0.0-RC1 or later. It is intended to work with Webpack 2 or 3.

Installation

  • Install with composer from your project directory:
composer require la-haute-societe/craft-webpack-assets 

Webpack setup

  • To generate the intended JSON files, add the following NPM packages:
yarn add html-webpack-plugin write-file-webpack-plugin underscore-template-loader -D
# Or
npm install html-webpack-plugin write-file-webpack-plugin underscore-template-loader --save-dev
  • Somewhere in your assets source folder, create a assets-files.json.tpl file with the following content :
<%= JSON.stringify( htmlWebpackPlugin ) %>
  • In the Webpack config add the following plugins :
{
    plugins: [
        new HtmlWebpackPlugin({
            filename: 'generated-assets-files.json',
            template: 'underscore-template-loader!path/to/templates/assets-files.json.tpl',
            inject: false,
            chunksSortMode: 'dependency'
        }),
        new WriteFilePlugin({
            test:  /generated-assets-files\.json$/,
            force: true,
            log: false
        })
    ]
}

Adjust the template value to the path of the previously created assets-files.json.tpl file.

  • Finally, run your Webpack process, as usual.

Configuration

In the config folder at the root of your Craft project, create a webpackassets.php file with the following content and adjust the path to the JSON generated by Webpack.

<?php

return [
    'jsonPath' => realpath(__DIR__ . '/path/to/generated-assets-files.json'),
];

Usage

In your Twig templates, you can include your Webpack generated assets as follow:

<html>
<head>
    ...
   
    {{ craft.webpackAssets.cssTags() | raw }}
    
    ... Or with chunk name ...
    {{ craft.webpackAssets.cssTags('app') | raw }}
   
    ...
</head>
<body>
...

{{ craft.webpackAssets.jsTags() | raw }}

... Or with chunk name ...

{{ craft.webpackAssets.jsTags('app') | raw }}
{{ craft.webpackAssets.jsTags('libs') | raw }}

...
</body>
</html>

You can detect if the public path provided by webpack is an absolute URL with the method isPublicPathAbsoluteUrl (this is the case when assets are served by Webpack).

If needed, you can override the webpack public path at runtime when this path is not absolute :

{% if not craft.webpackAssets.isPublicPathAbsoluteUrl() %}
<script>
    runtime_webpack_public_path = '{{ siteUrl }}assets/';
</script>
{% endif %}
