RN Integration with Existing Apps
- Set up directory structure
To ensure a smooth experience, create a new folder for your integrated React Native project, then copy your existing iOS project to a /ios subfolder.

}
}
运行命令： npm install react-native
安装 react-native 依赖包

最近在读代码整洁之道，有个建议，所有的代码都要写测试用例，覆盖尽量100%， 我呆过的几家公司里， 很少有做到这样的， 大家不愿意写测试用例的原因，时间不够， 都交给专业的测试人员去做测试覆盖， 如果是每次发版本之前都跑一边测试用例最好。
