ProseMirror 1.0
Two years ago, I started the ProseMirror project because I wanted to take a stab at a better approach to WYSIWYG-style editing. Today, I'm releasing version 1.0 of the library . The architecture and scope of the project have changed quite a bit during its lifetime, but I feel that the original goal has been met.

Refresh Is Sacred
There are two kinds of client applications: The first kind has a “refresh” or “reload” button to make sure your app’s in sync with its server’s view of the world. The second kind is broken.

Windows 3.1 All Over Again
Reactive programming and thread sharing. Javascript, Node.js, Go, Rails, Elixir and Erlang. Rewind the clocks to Windows 3.1 In 1992 with Windows 3.1 we had this thing non-preemptive multitasking, i.e. “Cooperative Multitasking”. Cooperation is a funny term, it should actually be “Programmer Controlled Multitasking”…

Deploying ES2015+ Code in Production Today
Most web developers I talk to these days love writing JavaScript with all the newest language features—async/await, classes, arrow functions, etc. However, despite the fact that all modern browsers can run ES2015+ code and natively support the features I just mentioned, most developers still transpile their code to…

The iPhones 8
These are solid year-over-year updates — at least as impressive as the iPhone 7 was over the iPhone 6S. If they hadn’t debuted alongside the iPhone X we’d be arguing about whether these are the most impressive new iPhone models since the iPhone 6.

I don’t know who the Web Audio API is designed for
WebGL is, all things considered, a pretty decent API. It’s not a great API, but that’s just because OpenGL is also not a great API. It gives you raw access to the GPU and is pretty low-level. For those intimidated by something so low-level, there are quite a few higher-level engines like three.js and Unity which are…

ASCII and Unicode quotation marks
Do not use the ASCII character 0x60 (grave accent) as a left quotation mark together with 0x27 (apostrophe), because it will look silly with modern correct fonts.

Betting on the Web – Why I Build PWAs

CSS in JavaScript is like replacing a broken screwdriver with your favorite hammer
There's a ton of interest these days in 'CSS in JS'. The premise is simple: CSS operates in a global namespace, which can result in undesirable side effects, spaghetti code, and extremely difficult to maintain codebases. JavaScript used to do this, and we fixed it by encapsulating everything in modules and using tools…

Web frameworks are transforming from runtime libraries into optimizing compilers
My current "investment thesis" is that what we call web frameworks are transforming from runtime libraries into optimizing compilers. When it comes to eking performance out of hand-authored JavaScript and accompanying runtime libraries, we've reached the point of diminishing returns.

HTML Components (HTC), introduced in Internet Explorer 5.5, offers a powerful new way to author interactive Web pages.
