The TinyWebEx modules are a collection of ES6 JavaScript modules for WebExtensions, also called add-ons in the Mozilla world.
They make common tasks you need to do in your add-on simpler without requiring you to ship with a lot of dependencies (that’s why we call them tiny). This is also made possible, because we do not support older browsers.
from the main Readme…
Basically, these are modules I have extracted from my first add-on (the Offline Qr Code Generator), refined with unit-tests and properly documented.
Also, I’ve already included/used them in other add-ons.
Obviously, they are made in a way anyone can use them and quite ready already.
Still TODO…
However, i have to say some things really still need some work. At first, I really need some ideas for an icon… 
But anyway, they are used in production already, so production-ready™.
Highlights
You can, e.g.:
- specify all your settings of your add-ons in pure HTML
- or in the same pure-HTML way localize your whole HTML page
- or display useful tips to your users under specific conditions
My main use case was to split them, so I can re-use them by myself, but I feel it’s a good idea to share it with the wider community, that’s why I’ve opened this thread.
