Curated PWA Links

Scott C. Krause | Saturday, Jul 9, 2022



It is not uncommon for a startup to develop a web app, an iPhone app, and an Android app. When management is convinced that a web app can be just as engaging as native they will decide to focus solely on the web app and get to market much quicker. Making a web app installable results in increased discoverability, traffic, visitor retention, sales per customer, and conversions. I believe that this project proves beyond doubt the immersive potential of browser APIs.

Progressive Web Apps bring speed and reliability to the web by supplying features that historically have only been available to native apps including offline access, responsiveness even when the network is unreliable, home screen icons, full screen experience, push notifications and background sync.

The Progressive Web App represents the single greatest leap in engagement opportunity since the introduction of the browser. Because of its intimate relationship with the phone the potential to influence the micro-moment behavior of its user is vast and largely unexplored.

Your website becomes a native app in both experience and performance. Your PWA is a first class citizen on an iPhone or Android. It resides on the homescreen and in the app drawer.

When it is tapped it will respond instantly with a custom splash screen even while offline.

Expanding what the web can do with features like file system access, media controls, app badging, WebAssembly, and full clipboard support. All of these capabilities are built with the web's secure, user-centric permission model, ensuring that going to a website is never a scary proposition for users.

Here's the Native App Problem

There is friction when a customer must discover your app, install it, and create an account. People have become resistant to installing new apps simply because the novelty has worn off.

Here's the PWA solution

A website that behaves like an app. The discovery and onboarding are frictionless because there is no need to install an app. It's Instant gratification.

When a Progressive Web App moves out of a tab and into a standalone app window, it transforms how users think about it and interact with it.

Between modern APIs, WebAssembly, and new and upcoming APIs, web applications are more capable than ever, and those capabilities are only growing.

The best and most practical PWAs (Progressive Web Apps)

Frequently Asked PWA Interview Questions


What are the minimum requirements to install a PWA?

Minimally you will need HTTPS, a service worker serving 200, a manifest, and some graphic files. A good way to find out what you need is to run the Lighthouse PWA audit in Chrome.

Is Progressive Web App a Native Mobile App?

No. A PWA does not require an installation via an App store. A PWA looks and acts like a native app, but it is not the same. A website that behaves like an app. The discovery and onboarding are frictionless because there is no need to install an app.

Do PWAs work without Internet connectivity?

Yes, a PWA has powerful caching mechanisms that allow it to serve content even while offline.

Does PWA work well on all browsers?

Yes. A PWA is built on core web technologies that are supported by all modern browsers and devices.

Can I create multiple PWAs on the same domain?

Yes. You can create multiple PWAs on the same domain. The origin of the service worker script URL has to be the same as the origin of the script that calls register(). A service worker can only control URLs and decendents of that origin as defined in the scope parameter.

Can I publish a Progressive Web App on the Google Play store?

Yes, You create a new app in the Google Play Console. You can test the app after uploading an app bundle and wrapping it in Bubblewrap (command line tool). Using the testing link you can install your PWA from the Play Store on Android or ChromeOS.

Does PWA require HTTPS?

Yes, a secure connection is required in order to protect you from nefarious websites. This protects your data because when a website is served on the HTTPS (SSL) protocol you can be assured that the information is protected in transit and that the site is who it claims to be.

The Neodigm 55 Heatmap component captures the amount of time that each card is visible to an end user on a laptop or mobile device.

The summation of card activity is then packaged into the analytics data layer to be consumed by Adobe Analytics or Google Analytics. Activity that occurs while offline will be updated upon reconnection to the network if the app has not been closed.

The Neodigm 55 Heatmap component utilized the Intersection Observer pattern to track when and for how long block elements (cards) are visible in the user agent viewport.

The component is configured to only report if a card is visible for greater than 3 seconds. This threshold is configurable. There are some edge cases wherein data may lose fidelity. For example if the user opens another tab or abruptly closes the browser while a card is within the viewport.

The component captures the existence of cards within the browser's viewport, however the application may partially obstruct the viewport with an overlaying menu. Meaning that the Heatmap may report that a particular card is in view a few microseconds before it is actually visible. This discrepancy is so small that it is not statistically significant.

The data layer entries that the heatmaps create are additive, meaning that there may be more than one for a single component. This is because the end user viewed a particular card component, exited the card, then reentered the card.

Solve Anagram Puzzle
Solve Anagram Puzzle
Do two strings contain the exact amount of letters to form two words?
/* An anagram is a word or phrase formed by rearranging the letters
of a different word or phrase, typically using all the original
letters exactly once. For example, the word anagram itself can be
rearranged into nag a ram, also the word binary into brainy. 🎯 🍰 🔥
