In reply to Ciprian Popescu.

@Ciprian This plugin is not intended to be a full-featured plugin to turn your site into a PWA. It's intended to provide a foundation for core that other themes and plugins can use to create PWAs.

@Peter This plugin is not intended to supersede your plugin. Rather, as the article notes it is intended to facilitate and empower your plugin. It looks like your plugin is LH Web Application? We've been collaborating with the authors of the SuperPWA as well as the Progressive WordPress plugin to work on a common API for core that can power them. We'd be happy to work with you as well.
