# TypeScript Example



Supports Expo iOS

Supports Expo Android

Supports Expo Web

```sh
npx create-react-native-app -t with-typescript
expo prebuild
```

TypeScript is a superset of JavaScript which gives you static types and powerful tooling in Visual Studio Code including autocompletion and useful inline warnings for type errors.

## 🚀 How to use

#### Creating a new project

- Install the CLI: `npm i -g expo-cli`
- Create a project: `npx create-react-native-app -t with-typescript`
- `cd` into the project

### Adding TypeScript to existing projects

- Create a blank TypeScript config: `touch tsconfig.json`
- Run `yarn start` or `npm run start` to automatically configure TypeScript
- Rename files to TypeScript, `.tsx` for React components and `.ts` for plain typescript files

> 💡 You can disable the TypeScript setup in Expo CLI with the environment variable `EXPO_NO_TYPESCRIPT_SETUP=1 expo start`
