Experience with building JS and Python bindings for a Go library

[Taco de Wolff]

I would like to know if anyone has experience with building bindings for JavaScript (NodeJS) and Python for a Go library. Who has worked on this, or does anybody know of libraries that have succeeded? In particular, I have successfully built working JS and Python bindings (see https://github.com/tdewolff/minify/tree/master/bindings), but I have two problems:

- How does the Go standard library (CGO) work in conjunction with forked/worker threads of JS/Python? See https://github.com/tdewolff/minify/issues/518#issuecomment-1256812343

- How can I prebuild binaries for Windows for a JS binding? In particular, node-gyp allows you to build addons which is working fine for Linux/MacOS, however they only permit using MSVC on WIndows and Go/CGO only can use GCC. I'm suspecting this is behind an error we have (Error: Module did not self-register)

I would love to hear about example or people with experience! Thanks in advance!

I used the following two libraries for running JS from Go: 

There is a V8 binding using Cgo: https://github.com/rogchap/v8go

And there is a pure Go JS interpreter: https://github.com/robertkrimen/otto

For CPython, there's github.com/go-python/gopy that tries to automatically wrap a Go package into a CPython module.

There's also go-python/gpython, a pure-Go Python3 interpreter (without all the batteries, though).

For JS, I guess there's GopherJS.

For automatic python bindings I have used github.com/go-python/gopy
https://github.com/justinfx/pygo-plugin/blob/main/go_plugin/client.go

And for pure cpython bindings I have used:

• py2: github.com/sbinet/go-python
• py3: github.com/DataDog/go-python3
