The Webpack Manifest Plugin is an extension for Grav CMS. It allows you to develop themes that use for example Webpack that generate versioned assets (css/js).
As these generated files have a unique name every time they are generated, you can't reference them in your template directly. Webpack outputs a manifest file which contains a mapping between the unversioned filename and versioned filename, which is used by this plugin to replace assets with the correct file.
Installing the Webpack Manifest plugin can be done in one of three ways: The GPM (Grav Package Manager) installation method lets you quickly install the plugin with a simple terminal command, the manual method lets you do so via a zip file, and the admin method lets you do so via the Admin Plugin.
To install the plugin via the GPM, through your system's terminal (also called the command line), navigate to the root of your Grav-installation, and enter:
bin/gpm install webpack-manifest
This will install the Webpack Manifest plugin into your /user/plugins-directory within Grav. Its files can be found under /your/site/grav/user/plugins/webpack-manifest.
To install the plugin manually, download the zip-version of this repository and unzip it under /your/site/grav/user/plugins. Then rename the folder to webpack-manifest. You can find these files on GitHub or via GetGrav.org.
You should now have all the plugin files under
/your/site/grav/user/plugins/webpack-manifest
NOTE: This plugin is a modular component for Grav which may require other plugins to operate, please see its blueprints.yaml-file on GitHub.
If you use the Admin Plugin, you can install the plugin directly by browsing the Plugins-menu and clicking on the Add button.
Before configuring this plugin, you should copy the user/plugins/webpack-manifest/webpack-manifest.yaml to user/config/plugins/webpack-manifest.yaml and only edit that copy.
Here is the default configuration and an explanation of available options:
# Enable/disable the plugin
enabled: true
# Path to manifest.json relative to your active theme
# For webpack use manifest.json. For Laravel Mix use mix-manifest.json.
filepath: manifest.jsonNote that if you use the Admin Plugin, a file with your configuration named webpack-manifest.yaml will be saved in the user/config/plugins/-folder once the configuration is saved in the Admin.
Usage is simple as in most cases you can directly replace {% do asset.css( ... with {% do manifest.css( ..., the API is mostly the same and serves as a wrapper around some of the asset manager functionality, see https://learn.getgrav.org/16/themes/asset-manager.
Supported: add(), addCss(), addJs()
