A comprehensive collection of recipes for using ServiceWorker – from Mozilla. Everything from relaying messages between a ServiceWorker instance and a page to offline fallback scenarios and utilizing the Web Push Notification API.

Francois walks us through his toolchain of choice when it comes to modern front-end development. It basically comes down to React, Redux, Babel, Webpack, ESLint, lodash, and a few others. I must say I disagree with their choice of Mocha, but their detailed analysis is still well worth a read.

Dor reveals the importance of having – and periodically taking care of – a side project. He highlights the value in showing off your code, sparking your creative interest, and testing out new ideas in a learning environment.

Desperately in need to get started with FRP (Functional Reactive Programming) – applied to JavaScript? Look no further! This guide by the folks at ReactiveX (the people behind Rx.js) is a great starting point.

Amjad looks at how we can implement some kind of memoization on top of Promises so that we only pull network intensive resources only when it’s necessary.
He covers a few different scenarios and explains trade-offs in each case.

Immutability is everywhere. Now you can use this ESLint (a JavaScript code linter) plugin to lock down your codebase entirely by preventing mutability at the static analysis level. A very interesting development; time will tell if it takes off.

Another one from a Netflix developer. Tim’s diffhtml package aims to provide smart virtual DOM diffing directly on the DOM. The package also comes with a prolyfill of how Tim would like diffhtml to be standarized in the future.

Phil drills deep into how the z-index property works under the hood. He takes steps to explain stacking order and context in more detail than you’d ever need to know.
