  • Don't upload your PWA to the app stores
    I built Progressier to provide developers with the best possible browser-based PWA installation experience. And I can say, it's nearly as good as Google/Apple's app store installation experience. - Source: dev.to / over 2 years ago
  • How to fix iOS push subscriptions getting terminated after 3 notifications
    That's it for me! Hopefully, now you know how to get around push subscriptions being canceled after 3 push notifications. If you have any questions, feel free to contact me here. - Source: dev.to / about 3 years ago
  • Web push notifications coming to iOS this year
    When I made Progressier compatible with the desktop Safari update from last October, I had to rewrite a thing or two to put the request for permission inside a click event listener. Doesn't work otherwise. I'd be willing to bet mobile Safari will have the same requirement. Source: over 3 years ago
  • Show HN: I made an indie app store alternative with a twist
    The twist is that although it does (part of) the job of an app store, it's not (nor aims to be) an app store. It's a script you add to your existing web app that makes it "self-distributing". Check it out: https://progressier.com. Under the hood, it leverages the concept of "PWA", but it goes further: 1. It creates an installation page for your app that looks like an app store listing. Demo example:... - Source: Hacker News / about 4 years ago
  • Does calling the image URL cost anything?
    With something like Progressier, you can set up a caching strategy that essentially says "cache all images located on firebase.whatever-the-url-is.com and never request it from the network after that". It would take approximately 2 minutes to set up -- no code required. Source: over 4 years ago

  • The text mode lie: why modern TUIs are a nightmare for accessibility
    > a locked down GUI that is efficient to use and designed to display the data that the commandline tools produce [...] You can have all that. There are various data presentation tools out there (one I can think of right now is Streamlit as I tried it out a few months ago, but I'm not really a data person, Python is just my primary language).
