Sveltekit! I used sveltekit-adapter-browser-extension[0] by Antony which conveniently handles the hashing stuff. I just made the repo public in case you want to check it out[1]. Let me know if you run into any issues!
It's definitely something we want to consider in the future! Right now, we want to focus on a single view framework and make the developer experience as seamless as possible with it. The framework we've chosen is React because we're most familiar with it.
Do you have any references that you could point me to on how to get Sveltekit running to build Chrome extensions?
Sorry for the digression, but this has been a bit of a bugbear for the past month and would dearly love to know how to get around it.
