You should create a new react native project without the default template. By using the '-template blank' option. This will create a react native project with 'App.js' as the entry point, and no typescript.

E.g)run this command npx create-expo-app appname --template blank

*** Update November 2024 ***

Option 1

Initialize the project with npx create-expo-app@latest or npx create-expo-app@latest --template blank-typescript

Option 2

Use the template with one command npx create-expo-app -t expo-ts.

For more info please read the Starting React Native Project in 2025 article.

*** Update January 2024 ***

Option 1

1. Initialize the project with npx create-expo-app command.
2. Create a tsconfig.json in your project root with touch tsconfig.json.
3. Rename App.js to App.tsx with mv App.js App.tsx.
4. Run yarn start or npm run start. It will prompt you to install the required dependencies (typescript, @types/react, @types/react-native), and automatically configure your tsconfig.json.
5. Switch to the "bare" workflow with npx expo eject command.

For more info see the docs on Expo Typescript support.

Option 2

Initialize the project with npx react-native init MyApp --template react-native-template-typescript command.

For more info see the docs on React Native Typescript support.

Option 3

Use the template with one command npx create-expo-app -t expo-ts.

*** Original Answer February 2022 ***

Option 1

1. Initialize the project with expo init command and choose minimal as a template. Or use this command: expo init --template bare-minimum --name <your-app-name>.
2. Create a tsconfig.json in your project root: touch tsconfig.json.
3. Rename App.js to App.tsx: mv App.js App.tsx.
4. Run expo start. It will prompt you to install the required dependencies (typescript, @types/react, @types/react-native), and automatically configure your tsconfig.json.

For more info see the docs on Expo Typescript support.

Option 2

Use the template with one command expo init --template @vladimir-vovk/expo-bare-typescript.

For more info please read Starting React Native Project in 2022 article.

!! Unfortunately, expo-template-bare-typescript package is outdated. It will install Expo 41.

I got it the correct command would be:

npx create-expo-app@latest --template

and select the blank from the options to get the bare minimum configuration, just like the React Native one with JavaScript.
