Go Steering

This library is intended to be a go implementation of OpenSteer. However this project doesn't work and is pretty much abandoned.

Copy the wasm_exec.js file to your project's directory cp "$(go env GOROOT)/misc/wasm/wasm_exec.js" .

Build the code and put it in main.wasm GOOS=js GOARCH=wasm go build -o main.wasm

Install goexec if needed

# install goexec: go get -u github.com/shurcooL/goexec

Run a webserver from the command line

$ goexec 'http.ListenAndServe(":8080", http.FileServer(http.Dir(".")))'
