API Architecture Comparison for Personal Projects

API Architecture Comparison for Personal Projects

Initially designed for self-contained apps, the need for data sharing, user authentication, and multi-app expansion necessitated a robust API and serverless infrastructure. After evaluating six setups – Swift-only, Swift+Firebase, React Native+Firebase, React Native+FastAPI+AWS, React Native+Supabase (direct access), and React Native+Next.js+Supabase – the author adopted React Native × Hono × Cloudflare Workers × Supabase as the optimal architecture.

Why This Matters

Many developers overestimate the complexity required for backend infrastructure, often opting for solutions that are either overly complex and expensive (like full AWS stacks) or lack essential security features (like direct database access). This comparison highlights the trade-offs, demonstrating that a serverless, lightweight approach can deliver enterprise-grade security and scalability without incurring significant costs, particularly crucial for personal projects that may evolve into larger applications.

Key Insights

• Serverless cost optimization: Cloudflare Workers can remain free for up to 100,000 requests per month.
• Saga pattern necessity: Direct client access to databases bypasses the ability to enforce complex business logic and data consistency, necessitating a robust API layer.
• Hono framework: Offers Express-like ergonomics with high performance, optimized for API-only use cases.

Practical Applications

• Personal Finance App: A developer building a personal finance app could use this architecture to securely manage user data and transactions across iOS and Android platforms.
• Pitfall: Directly accessing Supabase from a React Native app without an API layer can lead to security vulnerabilities and difficulties in enforcing business rules.
