# Full-Stack Development Workflow Server-first development workflow for Next.js + TypeScript projects. ## Steps ### 1. Understand the Requirement Parse the request into concrete deliverables. Ask clarifying questions if the scope is ambiguous. ### 2. Check Existing Patterns Grep for similar implementations in the codebase. Read existing conventions for data fetching, state management, validation, and error handling. Follow what's already there. ### 3. Design Data Layer First - Define or update database schema (Drizzle migrations, Prisma, raw SQL) - Define Zod validation schemas that will be shared between client and server - Infer TypeScript types from Zod schemas ### 4. Implement Server-Side - API routes or Server Actions with input validation - Database queries with parameterized inputs - Auth checks on protected endpoints - Error handling that returns safe messages to clients ### 5. Implement Client-Side - Server Components for data fetching (default) - Client Components only where needed (interactivity, state, browser APIs) - Loading and error states for all async operations - Optimistic UI where appropriate ### 6. Validate End-to-End - Zod schemas enforce the contract at both boundaries - Type errors caught at compile time via `z.infer` - Runtime validation catches bad data at system boundaries ### 7. Write Tests - Unit tests for business logic and utilities - Integration tests for API routes and data flows - Component tests for interactive UI ### 8. Verify in
