**Project:** Weekly Task Management App
**Researched:** January 24, 2026

## Recommended Stack

### Core Framework
| Technology | Version | Purpose | Why |
|------------|---------|---------|-----|
| React | 18.x | Frontend UI framework | Component-based architecture, strong ecosystem, excellent for UI-heavy applications |
| Node.js | 18.x | Backend runtime | Mature ecosystem, good performance, large community support |
| Express.js | 4.x | Web framework | Lightweight, flexible API development, widely adopted |

### Database
| Technology | Version | Purpose | Why |
|------------|---------|---------|-----|
| PostgreSQL | 14+ | Relational database | ACID compliance, strong data integrity, excellent for structured data like tasks |
| Prisma | 5.x | ORM | Type-safe database access, migration management, reduces boilerplate |

### Infrastructure
| Technology | Version | Purpose | Why |
|------------|---------|---------|-----|
| Vercel | Latest | Deployment platform | Seamless React deployment, automatic CI/CD, global CDN |
| Supabase | Latest | Backend-as-a-Service | Provides auth, storage, and database as managed services |
| GitHub Actions | Latest | CI/CD pipeline | Integrated with GitHub, reliable deployment automation |

### Supporting Libraries
| Library | Version | Purpose | When to Use |
|---------|---------|---------|-------------|
| Zustand | 4.x | State management | For global state like user preferences and task data |
| React Query | 5.x | Data fetching | For server state management and API data synchronization |
| Tailwind CSS | 3.x | Styling framework | Rapid UI development with utility-first approach |
| date-fns | 2.x | Date manipulation | Lightweight, functional date utilities |
| react-beautiful-dnd | 14.x | Drag-and-drop | Excellent for implementing drag-and-drop functionality |

## Alternatives Considered

| Category | Recommended | Alternative | Why Not |
|----------|-------------|-------------|---------|
| Frontend Framework | React | Vue.js | While Vue is great, React has stronger ecosystem and community support for this type of application |
| Database | PostgreSQL | MongoDB | MongoDB is document-based and less suitable for structured relational data like task relationships |
| Backend Framework | Express.js | NestJS | NestJS adds overhead for this application's simpler requirements |
| State Management | Zustand | Redux | Redux has more boilerplate and complexity for a single-user task manager |
