Its been recommended a few times in these forums to use progressier for PWA apps. It looks like exactly what I need and I am ready to jump into it.
However, I have a question on initial set up. Wappler is not listed as a supported app builder. SO what do you choose for frameworks? Just 'HTML/CSS/JS'?
I've been using Progressier for quite some time now, yup, all you need to do is select HTML/JS/CSS, then setup your service worker and manifest link, and you're all set!
You're welcome!
Also, remember to add your localhost or internal ip(if you're using any devices on your local network) to additional domain list, you then can install your application from localhost and test push notifications and other features.
Also let me know whether you need a script to attach user's information to the progressier's notification subscriber list! Makes it much easier to target specific users via tags, email,etc.
