All of the above! Here you can play with the various styling options easily and see the code it generates.

You can see the comprehensive configuration options at the Github page here.

I've tested it on Sveltekit and in pure HTML (it's been awhile and so I can't quite remember if I've tested it on React), but if developers would find that helpful I'll consider adding a React or Vue example to the repo.

Realizing after I made the post that somehow I forgot to add the demo site link! You can play around with the style and data here if you just want to make a quick QR code to copy/screenshot without installing the web component: bitcoin-qr.blu.cx

This is just a version that I intentionally styled, but by default it's just a regular old QR code. Here's some examples, the top left is the default:

Checkout the demo site: bitcoin-qr.blu.cx. You can play with all the styling options and see the code there.

Also, if you prefer that the image be embedded in the QR rather than overlaying it, there's a boolean attribute you can set for that: image-embedded

Awesome! Looking forward to seeing what you build!

Thanks! for the comment and the micropayment!
