The only I still need to do is show the detected QR code in a nice interface. If you click on the QR code icon it will copy it to the clipboard.

Nice thing is that because all the heavylifting is in the wasm engine that it runs quite smoothly even on an older mid range processor like a snapdragon 625
What I did in a nutshell to get quirc in the browser
- Add a cpp wrapper to quirc
- Make a webidl file such that emscripten knows how to map cpp class to javascript
- Build the wasm and corresponding js binding with emscripten
- Write a wrapper QuircJS.js around this to make using the resulting library easier
This looks interesting and useful, but I'm not sure that I'd be able to maintain it as quirc changes.
Would it be feasible to start a separate project to maintain the bindings and build rules?
Cheers, Daniel

Hi Daniel,
I can help you maintain it in your repo. Maintenance should be very low. I just have a CPP wrapper around your public API. So only if you change the public API there would be a need to do changes in my code. However if you prefer I can make a QuircJS project that pulls in quirc as a submodule.
Let me know what you think is the best
Jaap

I think it's probably cleaner to maintain it as a separate repository pulling in a submodule -- then you'd be free to pull in whatever tooling you like. Currently, I'd prefer to keep the core library dependent on as few tools and libraries as possible as it needs to run on a wide variety of platforms.

Daniel,
I made a separate repo https://github.com/JaapHaitsma/QuircJS where I put quirc as submodule. So closing this merge request.
Should we have a list of theses type of projects, i.e. "versions" of quirc, in the README?

That would probably be a good idea, if you're happy to compile the list!
