Project Setup & Architecture

Set up a React Native/Expo project by installing TypeScript and tooling, initializing tsconfig, creating a standardized directory structure (app, features, shared, db), integrating SQLite with Drizzle for the data layer, adding Zustand for state management, and configuring Jest, ESLint, and Prettier for testing and code quality.

Use a modular directory structure with separate folders for app, features, shared components/hooks/utils/types, database schema and migrations, and theme configuration. This standardized layout supports reproducible builds, feature isolation, and easier team collaboration on React Native/Expo projects.

Yes, Expo supports SQLite through expo-sqlite, and you can pair it with Drizzle ORM for type-safe database operations. This combination provides a local data layer suitable for React Native mobile applications with schema versioning through Drizzle migrations.

Run npx tsc --init to generate a base tsconfig, then apply strict TypeScript options for robust type checking. Install @types/react and @types/react-native as dev dependencies to enable type support across your Expo application.

Add Jest for unit and component testing, ESLint for code standards, and Prettier for consistent formatting. Install as dev dependencies and configure alongside your TypeScript setup to enforce code quality and catch errors early in React Native development.

Yes, the infrastructure setup applies to bootstrapping new React Native/Expo projects and can be adapted to initialize development environments or new feature modules within existing applications that need standardized configuration and reproducible builds.
