# Architecture Decision Record (ADR) Version: 1.0 Project: Babees Place --- # Purpose This document records important architectural and engineering decisions made during the development of Babees Place. The purpose is to explain **why** decisions were made so that future contributors and AI assistants understand the reasoning behind the architecture. Architecture decisions should only change after careful review. --- # ADR-001 ## Title Use React + Vite for the Frontend ### Status Accepted ### Decision The frontend is built using React with Vite. ### Reason - Fast development server - Excellent build performance - Large ecosystem - Easy deployment - Modern tooling --- # ADR-002 ## Title Use Tailwind CSS ### Status Accepted ### Decision Tailwind CSS is the primary styling framework. ### Reason - Utility-first approach - Rapid UI development - Consistent design - Easy maintenance - Small production bundle --- # ADR-003 ## Title Use Supabase as the Backend ### Status Accepted ### Decision Supabase replaces the traditional Express backend. ### Reason - PostgreSQL database - Built-in authentication - Row Level Security - Storage - Realtime features - Reduced infrastructure - Faster development ### Consequences Business logic should be implemented using: - Database functions - Edge Functions (when appropriate) - Client services --- # ADR-004 ## Title Single Repository Architecture ### Status Accepted ### Decision Maintain one Git repository for the entire project. ### Reason - Easier maintenance - Simpler deployments - Consistent versioning - Better AI context - Reduced complexity --- # ADR-005 ## Title Security First Development ### Status Accepted ### Decision Security always takes priority over development speed. ### Reason Customer information must remain protected. The application should be production-ready from the beginning. ### Rules Never disable RLS. Never expose secrets. Never bypass authentication. Never bypass authorization. --- # ADR-006 ## Title Use Row Level Security ### Status Accepted ### Decision Every application table must use Row Level Security. ### Reason Authorization belongs in the database. This prevents accidental data exposure. --- # ADR-007 ## Title Use Role-Based Authorization ### Status Accepted ### Decision Authorization is based on user roles. Roles include: - Customer - Admin ### Reason Provides clear separation between administrative and customer functionality. --- # ADR-008 ## Title Documentation-Driven Development ### Status Accepted ### Decision Major features require documentation updates. ### Reason Documentation improves maintainability. AI assistants rely on accurate documentation. New contributors can understand the project quickly. --- # ADR-009 ## Title Component-First Development ### Status Accepted ### Decision Build reusable components before writing duplicate UI. ### Reason Improves consistency. Reduces maintenance. Encourages reuse. --- # ADR-010 ## Title Business Logic Separation ### Status Accepted ### Decision Business logic should not live inside UI components. ### Reason Improves readability. Improves testing. Improves maintainability. --- # ADR-011 ## Title AI-Assisted Engineering ### Status Accepted ### Decision AI is used as an engineering assistant rather than an autonomous developer. ### Reason Human review ensures quality and architectural consistency. AI accelerates implementation and documentation while people make the final decisions. ### Responsibilities AI should: - Explain changes. - Review security. - Recommend improvements. - Update documentation. - Follow engineering standards. AI should not: - Make destructive changes without approval. - Weaken security. - Remove documentation. - Introduce unnecessary complexity. --- # ADR-012 ## Title Production-Ready Code Standard ### Status Accepted ### Decision Features are only considered complete when they meet production standards. ### Definition of Done - Feature works correctly. - Security reviewed. - RLS reviewed. - Documentation updated. - Build passes. - Responsive. - Accessible. - Error handling implemented. - Loading states implemented. - No unnecessary code. --- # ADR-013 ## Title Git Workflow ### Status Accepted ### Decision Use small, focused commits. ### Rules Commit often. Use descriptive commit messages. Never commit: - node_modules - dist - .env - temporary files Review code before pushing. --- # ADR-014 ## Title Folder Structure ### Status Accepted ### Decision The repository follows a predictable structure. ```text babees_place/ │ ├── frontend/ ├── supabase/ ├── docs/ ├── scripts/ ├── .github/ ├── README.md └── .gitignore ``` ### Reason Improves navigation. Simplifies onboarding. Makes AI assistance more accurate. --- # ADR-015 ## Title Continuous Improvement ### Status Accepted ### Decision Every change should improve the project. ### Principle Leave the codebase cleaner than you found it. Reduce technical debt whenever practical. Avoid quick fixes that create future problems. --- # Future ADRs Every significant architectural decision should be added here. Examples: - Introduce Redis caching. - Add a recommendation engine. - Introduce microservices. - Replace Cloudinary. - Add mobile applications. - Add multi-vendor support. Each new ADR should include: - Title - Status - Decision - Reason - Consequences
