Go JavaScript Bindings

Highly experiemental, I'm not even sure these work currently. Original author is Robery Johnstone, and his mercurial repository can be found at I have updated the bindings to work with the latest changes to the reflect API, bits of it manually. The entire test suite minus one function (finally!) passes.

Update (2013/10/16): The test suite does not work at all, but it compiles again with go 1.0. Feel free to hack away at this if you think it might be useful :).

Update (2013/12/26): Thanks to @sqs, the test suite now passes. This library should still be considered "experimental", but should work.


go get


package main

import (

func main() {
    ctx := gojs.NewContext()
    defer ctx.Release()

    ret, err := ctx.EvaluateScript("['hello', 'world'].join(' ')", nil, ".", 0)

    if err != nil {
        fmt.Println("Script had an error :(", ctx.ToStringOrDie(err))

    if ret == nil {
        fmt.Println("Nothing returned...")

    retstr := ctx.ToStringOrDie(ret)



(for anyone interested)

  1. Get the test suite to pass ;)
  2. Move as many functions as possible off of context. We should be able to make a nicely broken-down API where the conceptual weight is lower. For example, all of the functions that take obj *Object as the first parameter should really just be functions on *Object directly.
  3. ???
  4. PROFIT! (i.e. make something cool).


There's not much documentation, because the original had no documentation. If I find a use for this beyond curiousity, I might add that as I go. Current documentation generated by godoc is available at
