This is a demo app running gPhoto2 on the Web:

Powered by a custom fork of libgphoto2, a custom fork of libusb, WebAssembly via Emscripten, and WebUSB.

For the detailed technical write-up, see the official blog post. To see the demo in action, visit the hosted version here (but make sure to read the cross-platform compatibility notes first). If you don't have a DSLR, you can check out the recording in the blog post.

Building

To build, you'll need Docker. Then:

./build.sh # runs build in Docker
npx serve ui # starts a local server with COOP/COEP
