Logo for the kthoom comic book reader

I use my open source comic book reader, kthoom, quite a bit (more than I probably should!). Every once in awhile, I’ll come across a comic book file that kthoom won’t open and I’ll delightedly set some time aside in the evening/weekend to work on fixing the JavaScript. Hacking keeps me sane. Read the rest of this entry …

ReactJS logo

I’ve been playing around a bit with React, since that’s where all the hot and shiny is lately. I really like it, but I can see some of the hot and shiny warts – I’ll blog about that later after I’ve been fully brainwashed had more time to play with it.

For the purposes of this exercise, one thing I’m trying to do is go the no-build-step route, where it’s all pure HTML and JavaScript. This means no JSX, no npm, no Babel. It’s really not too bad at all (unfortunately almost all examples I’ve seen online use JSX – and understandably).

It’s also given me a good stretch at using ES6 modules natively, one hot and shiny wart I’ve noticed there too.

JavaScript logo

The last piece heralding the dawn of modern JavaScript (sometimes thought of as ES6, but we’re past that now) arrived last month when two browsers (Chrome and Safari) shipped support for ES6 modules natively without developer flags. It’s now possible to write all this stuff (modules, classes, arrow functions, const/let variables, Promises) using just your code and not relying on transpilers!

I want to believe. SVG as an image format.As promised, I have a tiny thing to announce here. I recently split off and refactored the code that deals binary data in kthoom into a new open source project: https://github.com/codedread/bitjs, Binary Tools for JavaScript.

The faster and faster JavaScript engines in modern browsers and the rise of new technologies like Typed Arrays, Web Workers, and the File APIs mean that browsers can actually be used to read in binary formats completely on the client-side (as long as native performance isn’t a requirement).

For now the library includes two main capabilities:

  • streams for reading in bits and bytes from a Typed Array
  • unarchiving zip, rar or tar files (that’s right, you can unzip and unrar in JavaScript now)

I want to believe. SVG as an image format.Oh, I forgot to mention a cool thing that happened at the beginning of the year while I was so busy: Wikipedia inched a step closer to having an in-browser editing experience for its impressive collection of vector image files via an experimental MediaWiki Extension. The extension was put together by Brion Vibber of StatusNet and WikiMedia fame. Fingers crossed for this to one day appear in Wikipedia! 🙂
