WordPress Service Worker Cache

A WordPress plugin for caching theme assets via a service worker for the sake of performance and offline functionality.

This plugin is currently experimental and should only be used with developers with Service Worker knowledge.

Build

To build the plugin, ensure you have Composer, then simply invoke composer install.

Installation and Usage

Assuming the build step completed successfully, place the wp-sw-cache directory inside your WordPress instance's wp-content/plugins directory.

With the plugin in the WordPress directory structure:

1. Activate the plugin
2. Navigate to the plugin's settings page
3. Choose assets from the listing that are used most frequently (style.css is likely used on every page of the blog, for example)
4. Save!

A service worker will then be placed within every page of the blog and select assets will be served from the service worker!

Install the plugin

Clone the repository and copy the folder wp-offline-content inside your WordPress plugins directory.

Activate the plugin from the Plugins menu in the Dashboard. Options are available to customize under the Offline content submenu in Settings.
