gowasmer

When compiling Go to WebAssembly, the Go compiler assumes the WebAssembly is going to run in a JavaScript environment. Hence a wasm_exec.js file is provided by the Go compiler and must be used. However, WebAssembly can actually run everywhere. So we need to use some hacks to make WebAssembly modules generated by the Go compiler runnable everywhere. And that's where gowasmer is useful.

gowasmer is a port of the wasm_exec.js file, for Go. It assumes the WebAssembly runtime is wasmer-go.

Alternatively, to avoid using gowasmer, you can compile your Go program to WebAssembly with TinyGo as follows:

$ tinygo build -o module.wasm -target wasi .

Usage
