Going Offline: Designing An Ideal Offline Experience With Service Workers By Jeremy Keith

Here’s a great even-handed in-depth review of Going Offline:

If you’re interested in the “offline first” movement or want to learn more about Service Workers, Going Offline by Jeremy Keith is a really gentle and highly accessible introduction to the topic. At times, it even felt “too gentle”, with Keith taking a moment here and there to explain what a “variable” is and what “JSON” (JavaScript Object Notation) is. But, this just goes to show you the unassuming and welcoming mindset behind writing a book like this one.

Async + Await

Slides from a conference talk with a really clear explanation of how async + await works with promises.

More fuel for the fire of evidence that far too many people think that progressive web apps and single page apps are one and the same.

The Promise of a Burger Party - Mariko Kosaka

Mariko has a real knack for explaining technical concepts in a very accessible way. This time it’s JavaScript promises.

Web fonts, boy, I don’t know – Monica Dinculescu

How we make RWD sites load fast as heck

Scott shares the code that Filament Group are using to determine which style declarations are critical (and can be inlined) and which are non-critical (and can be loaded asynchronously). It makes quite a difference in perceived performance.

By the way, I really, really like the terminology of “critical” and “non-critical” CSS, rather than “above the fold” and “below the fold” CSS.

chartbeat - real-time website analytics and uptime monitoring

This looks like an interesting approach to web analytics: a JavaScript function pings the service every 10 seconds allowing for a near realtime overview.
