The Chrome team is going to release a Headless Chrome version soon. They’ve been working on it for a while.

The aim of the Headless Chrome project is to produce a version of Chrome that can run in a headless/server environment. Expected use cases include loading web pages, extracting metadata (e.g., the DOM) and generating bitmaps from page contents – using all the modern web platform features provided by Blink.

The main deliverables are:

1. A library which headless applications can link to to.
2. A sample application which demonstrates the use of headless APIs.

A hands-on introductory book on the art of modern application and infrastructure monitoring and metrics.

Looks like an interesting book on a subject we seldom inform ourselves about as web developers, but definitely something to take into account. If anything, store your server logs somewhere you can access later!

Flexbox is awesome, but it introduces many new concepts that can make it difficult to use. These interactive examples will show you practical ways to use it to build UI components. They start out simple and get more complex near the end. You can start using these patterns in your own code right away, though I recommend you apply accessibility best practices to the markup (like using semantic HTML5 elements).

eBay has compiled a list of patterns and antipatterns when it comes to accessibility. If anything, scan through the extensive list of samples that they’ve compiled.

Harry helps us use static analysis to learn where to improve our CSS. In this case, he brings up parker, a tool that lists unique colors, median selector specificity, density, and selectors-per-rule – among other interesting metrics regarding your style sheets.

Quite useful, give it a go! Also, read Harry’s review because his articles are always amazing!

Guille walks you through async / await in JavaScript, outlining its benefits and how they tie back into Promises.

_{You can find a lot of material on these topics on Pony Foo as well!}

Check out ES6 Promises in Depth, Asynchronous I/O with Generators & Promises, ES6 Generators in Depth, and ES6 Iterators in Depth.

There’s some pretty great ES6 content in Guille’s blog, as well.

Justin Searls came up with an excellent test smells repository-based workshop A workbook repository of example test smells and what to do about them.
