Tools like srcset allow developers to serve an optimized image variant in a responsive way, but it can be cumbersome and inefficient to use in practice. Developers can now negotiate with the server to download the best image variant for a device using straightforward HTTP request headers. These headers communicate DPR, Viewport-Width, and the intended display width of the resource being fetched to the server...

Web technologies have become powerful enough that they are used to build full-featured applications; this has been true for many years in the desktop and laptop computer realm, but is increasingly so on mobile devices as well...

Last week, Bootstrap turned four-years-old, and its creators, Mark Otto and Jacob Thornton, released Bootstrap 4 alpha. This alpha version is obviously incomplete still and shouldn’t be used just yet on production, but it does give us insight into all the cool new things that were added or updated. It’s also worth noting, that given […]

I’ve been using promises in my JavaScript code for a while now. They can be a little brain bending at first. I now use them pretty effectively, but when it came down to it, I didn’t fully understand how they work. This article is my resolution to that. If you stick around until the end, you should understand promises well too...

It’s well known that NGINX uses an asynchronous, event-driven approach to handling connections. This means that instead of creating another dedicated process or thread for each request (like servers with a traditional architecture), it handles multiple connections and requests in one worker process. To achieve this, NGINX works with sockets in a non-blocking mode and uses efficient methods such as epoll and kqueue...

The arrival of HTTP/2 will require a bit of re-thinking how we handle websites (and webservers). This makes it a good time to reflect on what those changes can bring. This post is based entirely on theory (the HTTP2 spec), as HTTP/2 is hard to test today. Major browsers support HTTP/2, but very little servers …

As creators of the web, we bring innovative, well-designed interfaces to life. We find satisfaction in improving our craft with each design or line of code. But this push to elevate our skills can be self-serving: Does a new CSS framework or JavaScript abstraction pattern serve our users or us as developers?

Today, the W3C published Pointer Events as a final Recommendation standard. This journey began a little over 2 years ago when we first submitted our proposal to the W3C for a common event model acr...
