This project allows you to build Go HTTP handlers to WebAssembly and embed it in a ServiceWorker to emulate an HTTP server!

I'd really appreciate to have feedback from people who would give it a try 🙂

The readme has a usage section and some examples to guide you.

Here is a video from FOSDEM 21 explaining how this works:

Contributions on the project are more than welcome.

Thanks!
