TurboStarter FAQ
What technical stack does TurboStarter use?
TurboStarter is built on a modern, scalable tech stack. The foundation is a Turborepo monorepo. The web app uses Next.js 14 with React, the mobile app is built with Expo (React Native), and browser extensions use WXT. The backend features Hono for API routes, Drizzle ORM for database operations, and PostgreSQL/Supabase for data storage. It uses Tailwind CSS for styling, Better Auth for authentication, and supports Stripe, Lemon Squeezy, and Polar for payments.
Do I need to be an expert developer to use TurboStarter?
While TurboStarter is powerful and comprehensive, it is designed to be accessible to developers with intermediate full-stack JavaScript/TypeScript experience. The codebase is well-structured and documented. The included CLI simplifies setup, and the pre-configured AI assistant rules help with code generation. However, comfort with React, Node.js, and basic deployment concepts is recommended to customize and extend the kit effectively.
How does the cross-platform code sharing work?
Code sharing is managed through the Turborepo monorepo architecture. Shared components, utility functions, TypeScript types, database schemas, and business logic are placed in dedicated internal packages. The web, mobile, and extension apps then import and use these shared packages. This ensures consistency and allows you to write a feature once and deploy it across all three platforms with platform-specific adaptations only where necessary.
What support and updates are included?
Purchasing TurboStarter includes lifetime access to all future updates to the core kit at no additional cost. Support is primarily provided through the dedicated Discord community, where you can ask questions, share ideas, and get help from other makers and the creator. The comprehensive documentation also serves as a key resource for setup, customization, and understanding the kit's architecture.
