安装依赖
npm install --save typescript @types/node @types/react @types/react-dom @types/jest
# or
yarn add typescript @types/node @types/react @types/react-dom @types/jest
添加配置文件
在项目根目录创建配置文件 tsconfig.json。
如果你使用了不支持 TS 的库，需要设置 skipLibCheck 为 true。
一般，我们还需要设置允许 any 类型，将 noImplicitAny 设置为 false。
{
"compilerOptions": {
"skipLibCheck": true,
"noImplicitAny": false,
......
}
}
