gojs example

This shows how to use Wasm built by go using GOOS=js GOARCH=wasm. Notably, this uses filesystem support.

$ go run cat.go /test.txt
greet filesystem

Internally, this uses gojs, which implements the custom host functions required by Go.

Notes:

• GOOS=js GOARCH=wasm wazero be removed after Go 1.22 is released. Please switch to GOOS=wasip1 GOARCH=wasm released in Go 1.21.
• GOWASM=satconv,signext enables features in WebAssembly Core Specification 2.0.
