PWA: Progressive Web All-the-things

Paul Kinlan

PWA. Progressive Web Apps. Frances Berriman and Alex Russell coined the term “progressive web apps” in 2015 with what I think is a seminal post “Progressive Web Apps: Escaping Tabs Without Losing Our Soul”. 3 years later, we’ve come a long way. From a loose collection of technologies - Service Worker, Manifest, Add to Homescreen, Web Push - that were originally only implemented in one browser engine, to a brand that has started to stick across the industry with businesses and developers, and all of the major browser vendors implementing the majority of the ‘PWA’ stack.

Page Lifecycle API - Philip Walton

Paul Kinlan

Philip Walton has an awesome deep dive into a new API the Chrome team has been working on to give you (the developer) control over how to respond when the browser unloads your tabs. Application lifecycle is a key way that modern operating systems manage resources. On Android, iOS, and recent Windows versions, apps can be started and stopped at any time by the OS. This allows these platforms to streamline and reallocate resources where they best benefit the user.

Add to homescreen changes in Chrome 68 - Pete LePage

Paul Kinlan

Pete LePage writes about important changes to Add to Homescreen in Chrome Add to Home Screen changes If your site meets the add to home screen criteria, Chrome will no longer show the add to home screen banner. Instead, you’re in control over when and how to prompt the user. To prompt the user, listen for the beforeinstallprompt event, then, save the event and add a button or other UI element to your app to indicate it can be installed.

PWACompat: the Web App Manifest for all browsers - @ChromiumDev

Paul Kinlan

Sam Thorogood from our team writes: You’ve designed a webapp, built its code and service worker, and finally added the Web App Manifest to describe how it should behave when ‘installed’ on a user’s device. This includes things like high-resolution icons to use for e.g. a mobile phone’s launcher or app switcher, or how your webapp should start when opened from the user’s home screen. And while many browsers will respect the Web App Manifest, not every browser will load or respect every value you specify.

Getting started with the Ambient Light Sensor

Paul Kinlan

Dean Hume’s been doing a lot great work with PWA’s recently, and he’s also been exploring a lot of the new platform API’s, in this case the Generic Sensor API: The Ambient Light Sensor API provides developers with the means to determine ambient light levels as detected by the device’s main light detector. This information is available to developers in terms of lux units. If you are building a Progressive Web App and you want to style it differently depending on the light levels in the room, then this could be the feature for you.

Understanding Storage Quota | Workbox

Paul Kinlan

Jeff Posnick writes, wrt to Workbox A common source of unexpectedly high quota usage is due to runtime caching of opaque responses, which is to say, cross-origin responses to requests made without CORS enabled. Browsers automatically inflate the quota impact of those opaque responses as a security consideration. In Chrome, for instance, even an opaque response of a few kilobytes will end up contributing around 7 megabytes towards your quota usage.
