Minimum Configuration WordPress PWA Plugin

Overview

This plugin is developed to focus on enhancing the loading experiences with minimum configuration.

The plugin's current features:

• use service worker to cache all static assets like images, JavaScripts, CSS styles, and fonts. It use Workbox as a library.
• use Intersection Observer API to lazy load images on page.
• make scripts loaded with async if no dependency found and defer if it has dependency like jQuery library. This is a bit risky if themes or plugins not include the scripts with wp_enqueue_script function or not include dependency when they enqueue the script. Make sure you check there is no error on JavaScript console when you activate the plugin.
• install service worker if the website has AMP plugin running. AMP is a custom elements library that boost the website loading performance.

This is still in beta, so please don't put it in productions until you know what you're doing.
