# 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
