SumUp is a simple tool that shows all possible combinations of numbers that add up to a given sum. It's useful for certain types of puzzles, like for example this killer sudoku.


FontAwesome provides thousands of icons, but you probably only use a few dozen on your website. Instead of loading all of them as a webfont, you could use SVG sprites.

This library is a simple helper that:

  • registers the icons you use in the place you use it,
  • dumps a refined set of SVG symbols at the end of your page.

Fair warning: this library is pretty useless. And only moderately fun... 🤷

But it seemed like a cool way to learn a bit about web components, so here it is: a component that creates googly eyes that follow your mouse.

jQuery used to be virtually indispensable, if you wanted to develop a cross-browser website without getting a headache.

Today, however, you might not need jQuery, especially, if you’re developing a library and want to avoid unnecessary dependencies.

Still, some helpers could be useful... Vanillin is an opinionated set of helpers that I find most useful, a bare minimum to make life easier.

While working on Avris Forms v4.0, I’ve decided to migrate some code from CoffeScript with jQuery to Vanilla JS. And I guess it might be a good idea to share this transition 😉
