I had a great time chatting with Lea and Emily about service workers on this episode of their podcast—they’re such great hosts!
Here’s the huffduffed audio.
Very valuable observations from Paul on his travels, talking to developers and business people about progressive web apps—there’s some confusion out there.
My personal feeling is that everyone is really hung up on the A in PWA: ‘App’. It’s the success and failure of the branding of the concept; ‘App’ is in the name, ‘App’ is in the conscious of many users and businesses and so the associations are quite clear.
What an excellent question! And what an excellent bit of sleuthing to get to the bottom of it. This is like linguistic spelunking on the World Wide Web.
Oh, and of course I love the little sidenote at the end.
I love having discussions like this!
A directory of progressive web apps.
Here’s an intriguing proposal that would allow web apps to indicate activity in an icon (like an unread count) in the same way that native apps can.
This is an interesting one because, in this case, it’s not just browsers that would have to implement it, but operating systems as well.
Adriana Blum lists progressive web apps that are doing very, very well from Twitter, Trivago, Starbucks, Forbes, Debebhams, West Elm, Washington Post, Pinterest, AliExpress, and Lancôme.
Instead of choosing between the immediacy of a mobile website and the rich experience offered by native apps, you can now offer your target audiences the best of both and improve the commercial performance of your business to boot.
Here’s a really quick (ten minute) talk about the offline user experience that I gave at the Delta V conference recently. I’m quite happy with how it turned out—there’s something to be said for having a short and snappy time slot.
There’s a common misconception that making a Progressive Web App means creating a Single Page App with an app-shell architecture. But the truth is that literally any website can benefit from the performance boost that results from the combination of HTTPS + Service Worker + Web App Manifest.
This is a good walkthrough of the flow you’d need to implement if you want to notify users of an updated service worker.
It is very disheartening to read misinformation like this:
A progressive web app is an enhanced version of a Single Page App (SPA) with a native app feel.
To quote from The Last Jedi, “Impressive. Everything you just said in that sentence is wrong.”
But once you get over that bit of misinformation at the start, the rest of this article is a good run-down of planning and building a progressive web app using one possible architectural choice—the app shell model. Other choices are available.
Sara describes the process of turning her site into a progressive web app, and has some very kind words to say about my new book:
Jeremy covers literally everything you need to know to write and install your first Service Worker, tweak it to your site’s needs, and then write the Web App Manifest file to complete the offline experience, all in a ridiculously easy to follow style. It doesn’t matter if you’re a designer, a junior developer or an experienced engineer — this book is perfect for anyone who wants to learn about Service Workers and take their Web application to a whole new level.
Too, too kind!
I highly recommend it. I read the book over the course of two days, but it can easily be read in half a day. And as someone who rarely ever reads a book cover to cover (I tend to quit halfway through most books), this says a lot about how good it is.
It’s so great to see the initial UX work that James and I prototyped in a design sprint come to fruition in the form of a progressive web app!
In the case of this web-app, if the tablets go offline, they will still store all the transactions that are made by customers. Once the tablet comes back online, it will sync it back up to the server. That is, essentially, what a Progressive Web App is — a kind of a website with a few more security and, most importantly, offline features.
This is such a great write-up of the workshop I did in Hong Kong!
Jeremy, it was a pleasure to work with you and you are always welcome here in Hong Kong!
If you fancy having this one-day workshop at your company, get in touch.
Here’s a Github issue that turned into a good philosophical debate on how to build a progressive web app: should you enhance your existing site or creating a separate URL?
(For the record: I’m in favour of enhancing.)

It’s really great to hear about how Microsoft will be promoting progressive web apps as first-class citizens …but it’s really unhelpful that they’re using this fudgy definition:
Progressive Web Apps are just great web sites that can behave like native apps—or, perhaps, Progressive Web Apps are just great apps, powered by Web technologies and delivered with Web infrastructure.
Although they also give a more technical definition:
Technologically speaking, PWAs are web apps, progressively enhanced with modern web technologies (Service Worker, Fetch networking, Cache API, Push notifications, Web App Manifest) to provide a more app-like experience.
Nice try, slipping notifications in there like that, but no. No, no, no. Let’s not fool ourselves into thinking that one of the most annoying “features” of native apps is even desirable on the web.
If you want to use notifications, fine. But they are absolutely not a requirement for a progressive web app.
(A responsive design, on the other hand, totally is.)
Squee! The next time there’s an update for OS X and iOS, Safari will magically have service worker support! Not only that, but Safari on iOS will start using the information in web app manifests for adding to home screen.
That’s an impressive turnaround.
This looks interesting—a new book by Dean Hume all about progressive web apps. A few chapters are available to download.
Here’s a nice one-sentence definition for the marketing folk:
A Progressive Web App is a regular website following a progressive enhancement strategy to deliver native-like user experiences by using modern Web standards.
But if you’re talking to developers, I implore you to concretely define a Progressive Web App as the combination of HTTPS, a service worker, and a Web App Manifest.
There’s a lot of misinformation on the internet as to how to build a PWA and how “appy” and SPA-y one must be.
This simply isn’t true. Disappointingly, It is what most of the documentation, blog posts and public discourse seem to imply.
I’m so, so happy to see some pushback against the misinformation that progressive web apps automatically imply client-side rendered single page apps built from scratch. There’s so much value to be had in turbo-charging an existing site into a progressive web app.
But what we don’t need is yet another TLA like Alien Web Apps.
