与C ++相对，有人可以在Go中编写本机Node.js扩展吗？

Question

That's all there is to my question, really, but I think it's an interesting thing to have answered.

Answer 1

Native module for node.js must deeply interact with V8 process which contains a lot of v8 concepts such as gc, javascript context, ...

And I don't think V8 has exposed compatible and stable APIs for other language to interact with it. That is why node.js native addon should be built with C++ and always imports V8 C++ headers.

But you can use GO to write node.js native addons by wrapping GO code with C++:

file: module.go

package main

func Add(a, b int) int {
    return a + b
}

file: module.c

#include <node.h>
#include <v8.h>

using namespace v8;

extern int go_add(int, int) __asm__ ("example.main.Add");

void init(Handle<Object> exports) {
    // call go_add
}

NODE_MODULE(module, init)

Quote: It might be doable for simple things like add (that don't generate garbage or require the runtime), but it's not supported (yet) by either compiler as far as I know. Part of the work is done for linux (see golang.org/issue/256), but there are a number of open questions (what happens when you load two shared objects? etc)
