WASI support in Go

Let’s go on a winding debugging adventure together. I thought I could get a Go HTTP handler running on Val Town and I thought it would be easy. Val Town is a social website to write and deploy Typescipt. Val Town doesn’t support Go, but it supports WASM. Can we make it all work!? If you want to skip all this and just run Go on Val Town you can follow the instructions here. There’s also a basic “Hello World” example, and another that’s much more fun and complex.

I share my experience compiling Go to WASM for a side project.

How we used WASM and some Go runtime modifications to run deterministic simulation tests against FrostDB
