Day 46: Learning Progressive Web App Fundamentals

Spent the day reviewing concepts on PWA. Progressive Web Apps (PWA) are apps built with web technologies. My key Takeaways:

The nine attributes of PWA.

  • Responsive
  • Connectivity Independent, progressive web apps work both offline an online.
  • Fresh: Always upto date
  • Safe, this is attributed to the fact that they are served by transport layer or secure https.
  • Discoverable
  • Re-engageable attributed to push notifications
  • Install-able
  • Linkable
  • have Applike interactions

Browser Capabilities available to PWA

  • Network Proxy available to change sniff and cache.
  • App packaging install-able with W3C
  • Background Syncing
  • Local storage
  • Game pad API
  • Page visibility API : lets us know if the user is physically looking at your browser.
  • Ability to capture audios and videos, ability to play back media.
  • Vibration function on receiving notifications.
  • Check battery status function.
  • Integrated payments

A manifest File
It is a Json file containing properties describing a progressive web app. I generated a favicon manifest with realfavicongenerator

    "name": "campReemerge",
    "short_name": "campReemerge",
    "icons": [
            "src": "/android-chrome-72x72.png",
            "sizes": "72x72",
            "type": "image/png"
    "theme_color": "#000000",
    "background_color": "#000000",
    "start_url": "/",
    "display": "standalone",
    "orientation": "any"
Enter fullscreen mode Exit fullscreen mode

Note to myself: There's a lot to learn, don't skip the fundamentals.
A few minutes into learning fundamentals
Also Me : Can i build something already.

Looking forward to the practical bit. I am done for today.
