Developers are lazy by nature: adhering to the DRY principle, writing scripts to automate things we’d otherwise have to do by hand, making use of third-party libraries. The traditional approach to cross-browser testing doesn’t align well with these ideals. Either you make a half-hearted attempt at manual testing or you expend a lot of effort on doing it “properly”. Once you’ve put in the effort of knowing your enemy, you’re able to attack in three steps: reconnaissance, raid and clearance. In this article, Chris Ashton hopes to save you hours of wasted effort by describing a testing strategy which is not only less labour-intensive, but more effective at catching bugs.

In this article, Rachel Andrew will look at the basics of HTTP2 as they apply to web designers and developers. She’ll explain some of the key features of the new protocol, look at browser and server compatibility, and detail the things you might need to think about as we see more adoption of HTTP2. You will get an overview of what to consider changing in your workflow in the short and long term. Rachel will also include plenty of resources if you want to dig further into the issues raised. Her aim is to give you enough of the background to be able to make good decisions as you plan your move to HTTP2.

In this article, James Miller and Mate Marschalko cover the basics of how to get started building for your own IoT devices using JavaScript. When building IoT devices, the task is typically divided between two roles: A hardware engineer creates the physical device, and a developer the ecosystem. However, this is not always necessary. In the case of JavaScript, its isomorphic nature allows for one language to be used across multiple platforms — including hardware. While the prospect of building your own hardware can be daunting, hopefully, after working through these two examples, you’ll be already thinking about the possibilities and planning your next project. Many components are compatible with the Johnny-Five library, meaning that the only limit is your imagination.

Ideally, we’d love to have one tool that would either generate “smart enough” crops and plug in the responsive images markup in the build automatically, or provide one interface to visually adjust the focal point of images and output “ready-to-go” markup. We aren’t quite there yet, but we might be soon. In the meantime, the tools listed in this article could be good enough options to consider when tackling a quite daunting task of producing art-directed variants of images — either manually or by building custom CMS plugins.

There have been some amazing quantum leaps in JavaScript tooling which have made it possible for you to dive head first into writing fully ES6 modules, without compromising on the essentials like testing, linting and (most importantly) the ability for others to easily consume what we write. In this article, Jim Cowart is going to focus on how to create a JavaScript package written in ES6 that’s usable in a site or app regardless of whether you’re using CommonJS, asynchronous module definition (AMD) or plain browser global modules.

Service workers do a lot of different things; there are myriad ways to harness their powers. In this article, Lyza Danger Gardner explains what a service worker is and how to put together your own by registering, installing, and activating it without any hassle. She decided to build a simple service worker for her website that roughly mirrors the features (provide a customized offline fallback experience, make the website function offline, and increase online performance by reducing network requests for certain assets) that the obsolete Application Cache API used to provide.

In this article, Nadav Soferman introduces a new free open source web tool that will allow you to generate breakpoints for your images interactively: the Responsive Breakpoints Generator. Nadav hopes this tool will help you address some of the challenges related to responsive images. This complexity is the driving force for new solutions that keep arising, such as the HTML5 picture element and srcset image attribute, the Client-Hints specification, and plenty of other client-side and server-side solutions.
