Smaller HTML Payloads with Service Workers — Philip Walton

This is a great progressive enhancement for performance that uses a service worker to combine reusable bits of a page with fresh content. The numbers are very convincing!

Alas, the code is using the Workbox library, but figuring out the vanilla code to write shouldn’t be too tricky seeing as Philip talks through his logic step by step.

Adding Response Metadata to Cache API Explainer by Aaron Gustafson and Jungkee Song

This is a great proposal that would make the Cache API even more powerful by adding metadata to cached items, like when it was cached, how big it is, and how many times it’s been retrieved.

How creating a Progressive Web App has made our website better for people and planet

Creating a PWA has saved a lot of kilobytes after the initial load by storing files on the device to reuse on subsequent requests – this in turn lowers the load time and carbon footprint on subsequent page views, making the website better for both people and planet. We’ve also enabled offline access, which significantly improves user experience for people in areas with patchy connections, such as mobile users on their commute.

Move Fast & Don’t Break Things | Filament Group, Inc.

This is the transcript of a brilliant presentation by Scott—read the whole thing! It starts with a much-needed history lesson that gets to where we are now with the dismal state of performance on the web, and then gives a whole truckload of handy tips and tricks for improving performance when it comes to styles, scripts, images, fonts, and just about everything on the front end.

Essential!

Request with Intent: Caching Strategies in the Age of PWAs – A List Apart

Aaron outlines some sensible strategies for serving up images, including using the Cache API from your service worker script.

The Layers Of The Web

Here are the slides from my opening keynote at Beyond Tellarrand on Thursday. They don’t make much sense out of context.

The Layers Of The Web - Jeremy Keith on Vimeo

Thanks to the quick work of Marc and his team, the talk I gave at Beyond Tellerrand on Thursday was online within hours!

I’m really pleased with how this turned out. I wasn’t sure if anybody was going to be interested in the deep dive into history that I took for the first 15 or 20 minutes, but lots of people told me that they really enjoyed that part, so that makes me happy.

Offline Page Descriptions | Erik Runyon

Here’s a nice example of showing pages offline. It’s subtly different from what I’m doing on my own site, which goes to show that there’s no one-size-fits-all recipe when it comes to offline strategies.

Why Progressive Web Apps Are The Future of Mobile Web [2019 Research]

PWAs just work better than your typical mobile site. Period.

But bear in mind:

Maybe simply because the “A” in PWA stands for “app,” too much discussion around PWAs focuses on comparing and contrasting to native mobile applications. We believe this comparison (and the accompanying discussion) is misguided.

Blog service workers and the chicken and the egg

This is a great little technique from Remy: when a service worker is being installed, you make sure that the page(s) the user is first visiting get added to a cache.

Offline listings

This is brilliant technique by Remy!

If you’ve got a custom offline page that lists previously-visited pages (like I do on my site), you don’t have to choose between localStorage or IndexedDB—you can read the metadata straight from the HTML of the cached pages instead!

This seems forehead-smackingly obvious in hindsight. I’m totally stealing this.

You are not connected to the Internet

This is a very cute offline page. Ali Spittel has written up how it was made too.

Distinguishing cached vs. network HTML requests in a Service Worker | Trys Mudford

Less than 24 hours after I put the call out for a solution to this gnarly service worker challenge, Trys has come up with a solution.

Offline fallback page with service worker - Modern Web Development: Tales of a Developer Advocate by Paul Kinlan

Paul describes a fairly straightforward service worker recipe: a custom offline page for failed requests.

Benjamin Parry Home-brew

I love the way that Benjamin is documenting his activities at Homebrew Website Club Brighton each week:

Another highly productive 90 mins.

Homebrew website club is on every Thursday evening 6.00-7.30pm at Clearleft. You should come along!

Benjamin Parry Offline Homebrewing

Two of my favourite things: indie web and service workers.

This makes me so happy. I remember saying when my book came out, that the best feedback I could possibly get would be readers making their websites work offline. The same can be said for the talk of the book.

Competing by mimicking - Andy Bell

In my mind, the only way to “compete” with native apps is to do better than native apps—and with the web platform consistently improving and enabling us to produce app-like experiences, with Service Workers, ES6+ JavaScript, modern CSS and Web Components: we are very much on the path to do better than native apps.
