# Twenty Architecture
|
|
|
|
## Tech Stack
|
|
- **Frontend**: React 18, TypeScript, Recoil, Styled Components, Vite
|
|
- **Backend**: NestJS, TypeORM, PostgreSQL, Redis, GraphQL
|
|
- **Monorepo**: Nx workspace with yarn
|
|
|
|
## Package Structure
|
|
```
|
|
packages/
|
|
├── twenty-front/ # React app
|
|
├── twenty-server/ # NestJS API
|
|
├── twenty-ui/ # Shared components
|
|
├── twenty-shared/ # Common types/utils
|
|
└── twenty-emails/ # Email templates
|
|
```
|
|
|
|
## Key Principles
|
|
- **Functional components only** (no classes)
|
|
- **Named exports only** (no default exports)
|
|
- **Types over interfaces** (except for extending third-party)
|
|
- **String literals over enums** (except GraphQL)
|
|
- **No 'any' type allowed**
|
|
- **Event handlers over useEffect** for state updates
