The base template for React-Native TypeScript with NativeBase.
npm install @native-base/react-native-template-typescript``sh`
npx react-native init MyApp --template @native-base/react-native-template-typescript
There seems to be quite some confusion about the legacy CLI. This template only works with the new CLI. Make sure you have uninstalled the legacy react-native-cli first (npm uninstall -g react-native-cli), for the below command to work. If you wish to not use npx, you can also install the new CLI globally (npm i -g @react-native-community/cli or yarn global add @react-native-community/cli`).
