Overview
The NestJS Monolithic Template is a comprehensive, production-ready starter template designed to accelerate backend development with NestJS. This template provides a solid foundation for building scalable, maintainable, and well-structured applications by incorporating industry best practices, common architectural patterns, and essential features out of the box.
Key Features
- Authentication & Authorization: JWT-based authentication with role-based access control (RBAC)
- Database Integration: TypeORM integration with support for multiple databases (PostgreSQL, MySQL, SQLite)
- API Documentation: Swagger/OpenAPI integration for automatic API documentation
- Validation: Comprehensive input validation using class-validator and class-transformer
- Error Handling: Centralized error handling with custom exception filters
- Logging: Structured logging with Winston and request/response logging
- Testing: Jest testing setup with e2e and unit test examples
- Environment Configuration: Environment-based configuration management
- Security: Helmet, CORS, rate limiting, and other security middleware
- Docker Support: Docker and Docker Compose configuration for easy deployment
Architecture
The template follows a modular architecture with clear separation of concerns:
- Modules: Feature-based modules with controllers, services, and entities
- Guards: Authentication and authorization guards
- Interceptors: Request/response transformation and logging
- Filters: Global exception handling
- Pipes: Input validation and transformation
- Middleware: Security and utility middleware
