Simple Expo Kit

Simple Expo Kit (SEK) is a production-ready React Native starter kit designed to significantly reduce the time and effort required to set up a new mobile application. It aims to transform weeks of infrastructure configuration and debugging into a mere 15-minute setup process, allowing developers and founders to focus on building their core product rather than boilerplate.

The kit comes pre-configured with a robust stack including Expo, Firebase, Supabase, RevenueCat, and NativeWind. This comprehensive integration provides a barebone app architecture that is ready for production from day one. Key features include:

• Authentication & Authorization: Supports both Firebase Auth and Supabase Auth, offering flexible options for user sign-in (Google, Email, X, Instagram, GitHub, Apple) with pre-baked Row-Level Security (RLS) rules for secure data access.
• Payments & Subscriptions: Seamlessly integrates RevenueCat for managing in-app purchases, subscriptions, and paywalls across App Store, Google Play, and Stripe (for web). It includes pre-configured paywall UI and handles subscription tiers.
• Database Flexibility: Offers a choice between Firebase Firestore (NoSQL) for fast queries and real-time listeners, or Supabase Postgres (SQL) with RLS rules, scheduled functions, and migration support.
• Serverless Computing: Facilitates backend operations with Firebase Cloud Functions or Supabase Edge Functions, enabling instant API and serverless logic execution.
• Push Notifications: Features a lean Firebase Cloud Messaging (FCM) setup for instant alerts across devices, with all necessary configurations done to avoid common debugging issues.
• UI & Styling: Utilizes NativeWind (Tailwind CSS for React Native) for a sleek light and dark theme system, providing full control over UI/UX without relying on heavy UI libraries.
• Developer Experience: Includes TypeScript for a strictly type-safe codebase, Expo Router for file-based routing, example screens (onboarding, paywall, dashboard, CRUD), and preconfigured .env setup.
• CLI & Migrations: For Supabase users, it provides local database management with the Supabase CLI and a clean SQL migration structure.
• AI-Assisted Development: The codebase is designed for AI-friendliness, featuring strict TypeScript typing and an Agents.md architecture guide specifically formatted for Large Language Models (LLMs) like Claude, Cursor, Gemini, and Grok. This allows AI assistants to extend features and refactor components while adhering to established patterns, significantly boosting productivity.
• Comprehensive Documentation: Detailed step-by-step guides cover setup, configuration, and deployment, along with troubleshooting for common errors like SHA-1 mismatches and Google Sign-In failures.

Simple Expo Kit is ideal for solo founders, developers, and agencies looking to accelerate their mobile app development, offering a robust, pre-tested foundation that saves days of initial setup and debugging.
