How can I integrate TypeScript with Expo?

To integrate TypeScript with Expo, you need to set up a new Expo project with TypeScript support. You can do this by running expo init my-project --template expo-template-blank-typescript.

What if I already have an existing Expo project?

If you have an existing Expo project, you can add TypeScript by installing the necessary TypeScript packages. Run npm install --save-dev typescript @types/react @types/react-native and then rename your files from .js to .tsx.

Are there any specific configurations I need to do?

Yes, you should create a tsconfig.json file in your project root. You can use the following basic configuration:

{
  "compilerOptions": {
    "target": "esnext",
    "module": "esnext",
    "jsx": "react-native",
    "strict": true
  }
}

Can I use third-party libraries with TypeScript?

Absolutely! Most popular libraries have TypeScript definitions. If a library doesn't, you can create your own type definitions or use @types packages if available.
