# napi-learning

流下了不会吸屁屁的泪水

## 环境

* Windows 10

* Node.js 8+

* Visual Studio 2015+

* node-gyp + Python 2.7 （可选）

### 只用VS

勾选使用C++的桌面开发（其中包括VC++ 2015或2017工具集）并安装。

基本配置：

1. 创建空项目

2. 资源管理器 → 项目 → 属性

3. 切换成所有配置 → 常规，目标文件扩展名：.node，配置类型：.dll

4. VC++目录，设置包含目录和库目录

5. 链接器 → 输入，附加依赖项：添加node.lib

6. 为了可以打断点调试，要设置Debug配置下的Node调试命令

node.exe，node.lib，调试平台三者必须对应。

### 用node-gyp

1. 根目录下创建 binding.gyp

2. node-gyp rebuild
