"WASM: Bringing Go to the Browser (and Beyond!)"

on YouTube ↗27m

" summary

Go 1.11 compiles Go into WebAssembly using GOOS=js GOARCH=wasm plus the syscall/js package and the provided wasmexec glue, letting Go call into DOM and expose Go functions to JavaScript. Demo converts a JS byte array image to grayscale with the Go image library and returns a JS typed array. CloudFlare Workers run the same WASM endpoint (gabbi.fish/grayscale). Containers add ~500ms cold start; Go WASM currently asks for ~1GB but work targets ~16MB.
