使用TS设置RN中的类型

npm install --save-dev typescript @types/react @types/react-native

{
  "compilerOptions": {
    "allowJs": true,
    "allowSyntheticDefaultImports": true,
    "esModuleInterop": true,
    "isolatedModules": true,
    "jsx": "react-native",
    "lib": ["es6"],
    "moduleResolution": "node",
    "noEmit": true,
    "strict": true,
    "target": "esnext"
  },
  "exclude": [
    "node_modules",
    "babel.config.js",
    "metro.config.js",
    "jest.config.js"
  ]
}

interface MyComponentProps {
  name: string;
  age: number;
}

const MyComponent: React.FC<MyComponentProps> = ({ name, age }) => {
  return (
    <View>
      <Text>Name: {name}</Text>
      <Text>Age: {age}</Text>
    </View>
  );
};
