環境：

Linux ： ubuntu 16.04
nodejs ： 10.15.2
node-gyp : 5.0.3
vs code : 1.36.1
vs code plugin(C/C++ ms-vscode.cpptools) : 0.24.1
GCC ： 5.4.0
Python : 2.7

1. 安裝nodejs

略過

參考：nodejs在Linux下的安裝

2.安裝node-gyp

略過

參考：nodejs在Linux下c++插件運行-安裝node-gyp

3.安裝vs code

略過

4.安裝c++插件

vs code應用商店所有C/C++,其中Microsoft發佈的就是，全名C/C++ for Visual Studio Code

源碼：
https://github.com/microsoft/vscode-cpptools

5.代碼

• hello.cc

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

using namespace v8;

void Method(const v8::FunctionCallbackInfo<Value>& args) 
{
  Isolate* isolate = Isolate::GetCurrent();
  HandleScope scope(isolate);
  args.GetReturnValue().Set(String::NewFromUtf8(isolate, "world"));
}

void Init(Handle<Object> exports) 
{
  Isolate* isolate = Isolate::GetCurrent();
  exports->Set(String::NewFromUtf8(isolate, "hello"),
      FunctionTemplate::New(isolate, Method)->GetFunction());

}

NODE_MODULE(hello, Init)

• binding.gyp

{
  "targets": [
    {
      "target_name": "hello",
      "sources": [ "hello.cc" ]
    }
  ]
}

• hello.js

var addon = require('./build/Debug/hello.node');

console.log(addon.hello()); // 'world'

6.單步調試

6.1 tasks.json配置

配置任務可以自動重新編譯.node

{
    "version": "2.0.0",
    "tasks": [
        {
            "taskName": "autobuild",
            "command": "node-gyp",
            "args": ["build"]
        }
    ]
}

6.2 lauch.json配置

通過lauch.json(調試 - 打開配置)來配置調試參數

{
    "version": "0.2.0",
    "configurations": [
        {
            //"type": "node",
            //"request": "launch",
            //"name": "Launch Program",
            // "program": "${workspaceFolder}/hello.js"
            "name": "C++ Launch",
            "type": "cppdbg",
            "request": "launch",
            "program": "/usr/local/bin/node",  //node路徑
            "args": ["${workspaceFolder}/hello.js"], //js路徑
            "preLaunchTask": "autobuild", //配合tasks.json自動編譯
            "stopAtEntry": false,
            "cwd": "${workspaceRoot}",
            "environment": [],
            "externalConsole": false,
            "linux": {
                "MIMode": "gdb",
                "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ]
            }
        }
    ]
}

6.3 調試

打斷點，F5開始調試即可
