Clean Architecture with DDD, CQRS & Event Sourcing 2 | 3 | This is an advanced boilerplate project implementing **Domain-Driven Design (DDD)**, **Clean Architecture**, **CQRS (Command Query Responsibility Segregation)**, **Event Sourcing** and MongoDB with NestJS. It provides a robust foundation for building scalable and maintainable enterprise-level applications with **proper separation of concerns** and **clean dependency direction**. 4 | 5 | If you want more documentation about NestJS, click here [Nest](https://github.com/nestjs/nest) 6 | 7 | > **📝 Note:** This version uses **MongoDB** with **Mongoose**. If you prefer the **PostgreSQL** version with **TypeORM**, you can find it at the original repository: [https://github.com/CollatzConjecture/nestjs-clean-architecture-postgres](https://github.com/CollatzConjecture/nestjs-clean-architecture-postgres) 8 | 9 | [A quick introduction to clean architecture](https://www.freecodecamp.org/news/a-quick-introduction-to-clean-architecture-990c014448d2/) 10 | 11 | ![Clean Architecture](https://cdn-media-1.freecodecamp.org/images/oVVbTLR5gXHgP8Ehlz1qzRm5LLjX9kv2Zri6) 12 | 13 | ## 🚀 Features 14 | 15 | ### Core Architecture 16 | 17 | - **Clean Architecture**: Enforces strict separation of concerns with proper dependency direction (Infrastructure → Application → Domain). 18 | - **Domain-Driven Design (DDD)**: Pure business logic encapsulated in Domain Services, accessed through Repository Interfaces. 19 | - **CQRS**: Segregates read (Queries) and write (Commands) operations for optimized performance and scalability. 20 | - **Event Sourcing**: Uses an event-driven approach with sagas for orchestrating complex business processes. 21 | - **Repository Pattern**: Clean interfaces defined in Domain layer, implemented in Infrastructure layer. 22 | - **Dependency Inversion**: Domain layer depends only on abstractions, never on concrete implementations. 23 | 24 | ### Proper Layer Separation 25 | 26 | - **Domain Layer**: Pure business logic, domain entities without framework dependencies, repository interfaces 27 | - **Application Layer**: Business orchestration, application services, CQRS coordination, framework-agnostic services 28 | - **API Layer**: HTTP controllers, DTOs, request/response handling, framework-specific HTTP concerns 29 | - **Infrastructure Layer**: Database implementations, external API calls, concrete repository classes, global services 30 | 31 | ### Security & Authentication 32 | 33 | - **JWT Authentication**: Implements secure, token-based authentication with refresh token rotation. 34 | - **Google OAuth2 Integration**: Secure third-party authentication with Google accounts, including CSRF protection. 35 | - **Role-Based Access Control (RBAC)**: Complete implementation with protected routes and role-based guards. 36 | - **Secure Password Storage**: Hashes passwords using `bcrypt` with salt rounds. 37 | - **Sensitive Data Encryption**: Encrypts sensitive fields (e.g., user emails) at rest in the database using AES-256-CBC. 38 | - **Blind Indexing**: Allows for securely querying encrypted data without decrypting it first. 39 | - **CSRF Protection**: OAuth flows protected against Cross-Site Request Forgery attacks using state parameters. 40 | 41 | ### Infrastructure & Operations 42 | 43 | - **MongoDB Integration**: Utilizes Mongoose for structured data modeling with a NoSQL database. 44 | - **Containerized Environment**: Full Docker and Docker Compose setup for development and production. 45 | - **Health Checks**: Provides application health monitoring endpoints via Terminus. 46 | - **Structured Logging**: Advanced logging system with business-context awareness and dependency injection. 47 | - **Application Metrics**: Exposes performance metrics for Prometheus. 48 | - **Data Visualization**: Comes with a pre-configured Grafana dashboard for visualizing metrics. 49 | - **Request Throttling**: Built-in rate limiting to prevent abuse and ensure API stability. 50 | 51 | ### Testing 52 | 53 | - **Unit & Integration Tests**: A suite of tests for domain, application, and infrastructure layers. 54 | - **E2E Tests**: End-to-end tests to ensure API functionality from request to response. 55 | - **High Test Coverage**: Configured to report and maintain high code coverage. 56 | - **Mocking**: Clear patterns for mocking database and service dependencies. 57 | 58 | ## Getting Started 59 | 60 | ```bash 61 | git clone https://github.com/CollatzConjecture/nestjs-clean-architecture 62 | cd nestjs-clean-architecture 63 | ``` 64 | 65 | ### 📁 Project Structure 66 | 67 | ``` 68 | . 69 | ├── doc/ 70 | │ ├── common.http # Common API requests 71 | │ └── users.http # User-specific API requests 72 | ├── src/ 73 | │ ├── api/ # API Layer (HTTP Controllers & DTOs) 74 | │ │ ├── controllers/ 75 | │ │ │ └── *.controller.ts # HTTP endpoints (auth, profile, hello) 76 | │ │ ├── dto/ 77 | │ │ │ ├── auth/ # Authentication DTOs 78 | │ │ │ │ └── *.dto.ts # Login & register DTOs 79 | │ │ │ └── *.dto.ts # Profile management DTOs 80 | │ │ └── api.module.ts # API module configuration 81 | │ ├── application/ # Application Layer (Business Orchestration) 82 | │ │ ├── __test__/ 83 | │ │ │ └── *.spec.ts # Application layer tests 84 | │ │ ├── auth/ 85 | │ │ │ ├── command/ # Auth commands & handlers 86 | │ │ │ │ ├── *.command.ts # Create/delete auth user commands 87 | │ │ │ │ └── handler/ 88 | │ │ │ │ └── *.handler.ts # Command handlers 89 | │ │ │ ├── events/ # Auth domain events 90 | │ │ │ │ └── *.event.ts # User created/deleted events 91 | │ │ │ ├── sagas/ 92 | │ │ │ │ └── *.saga.ts # Registration flow orchestration 93 | │ │ │ ├── decorators/ 94 | │ │ │ │ └── *.decorator.ts # Custom decorators (roles) 95 | │ │ │ ├── guards/ 96 | │ │ │ │ └── *.guard.ts # Authentication & authorization guards 97 | │ │ │ ├── *.strategy.ts # Auth strategies (JWT, local, Google OAuth) 98 | │ │ │ └── auth.module.ts # Auth module configuration 99 | │ │ ├── decorators/ 100 | │ │ │ └── *.decorator.ts # Global decorators (current user) 101 | │ │ ├── interfaces/ 102 | │ │ │ └── *.interface.ts # Application interfaces 103 | │ │ ├── interceptors/ 104 | │ │ │ └── *.interceptor.ts # Request logging interceptors 105 | │ │ ├── middlewere/ 106 | │ │ │ └── *.middleware.ts # HTTP middleware (logging) 107 | │ │ ├── services/ 108 | │ │ │ └── *.service.ts # Application services (auth, profile, logger) 109 | │ │ ├── profile/ 110 | │ │ │ ├── command/ # Profile commands & handlers 111 | │ │ │ │ ├── *.command.ts # Profile commands 112 | │ │ │ │ └── handler/ 113 | │ │ │ │ └── *.handler.ts # Command handlers 114 | │ │ │ ├── events/ # Profile domain events 115 | │ │ │ │ └── *.event.ts # Profile events 116 | │ │ │ └── profile.module.ts # Profile module configuration 117 | │ │ └── application.module.ts # Application module aggregator 118 | │ ├── domain/ # Domain Layer (Pure Business Logic) 119 | │ │ ├── __test__/ 120 | │ │ │ └── *.spec.ts # Domain layer tests 121 | │ │ ├── aggregates/ # Domain aggregates 122 | │ │ ├── entities/ 123 | │ │ │ ├── *.ts # Pure domain entities (Auth, Profile) 124 | │ │ │ └── enums/ # Domain enums 125 | │ │ │ └── *.enum.ts # Role enums, etc. 126 | │ │ ├── interfaces/ 127 | │ │ │ └── repositories/ # Repository contracts defined by domain 128 | │ │ │ └── *.interface.ts # Repository interfaces 129 | │ │ └── services/ 130 | │ │ └── *.service.ts # Pure business logic services 131 | │ ├── infrastructure/ # Infrastructure Layer (External Concerns) 132 | │ │ ├── database/ 133 | │ │ │ ├── database.module.ts # Database configuration 134 | │ │ │ └── database.providers.ts # Database providers 135 | │ │ ├── health/ 136 | │ │ │ └── *.check.ts # Health check configurations 137 | │ │ ├── logger/ 138 | │ │ │ └── logger.module.ts # Global logger module 139 | │ │ ├── models/ 140 | │ │ │ ├── *.model.ts # MongoDB models (auth, profile) 141 | │ │ │ └── index.ts # Model exports 142 | │ │ └── repository/ 143 | │ │ └── *.repository.ts # Repository implementations 144 | │ ├── main.ts # Application entry point 145 | │ ├── app.module.ts # Root application module 146 | │ └── constants.ts # Application constants 147 | ├── test/ 148 | │ ├── *.e2e-spec.ts # End-to-end tests 149 | │ ├── jest-e2e.json # E2E test configuration 150 | │ └── setup-e2e.ts # E2E test setup 151 | ├── prometheus/ 152 | │ └── prometheus.yml # Prometheus configuration 153 | ├── docker-compose*.yml # Docker Compose configurations (dev, prod) 154 | └── Dockerfile # Container definition 155 | ``` 156 | 157 | ## 🏗️ Architecture Overview 158 | 159 | ### Layer Architecture 160 | 161 | This project follows a strict 4-layer architecture: 162 | 163 | 1. **API Layer** (`src/api/`): HTTP controllers, DTOs, and request/response handling 164 | 2. **Application Layer** (`src/application/`): Business orchestration, CQRS coordination, and application services 165 | 3. **Domain Layer** (`src/domain/`): Pure business logic, entities, and domain services 166 | 4. **Infrastructure Layer** (`src/infrastructure/`): Database, external services, and technical implementations 167 | 168 | ### Module Structure 169 | 170 | -

Use the following command to generate a cryptographically strong secret: 523 | 524 | ```bash 525 | node -e "console.log(require('crypto').randomBytes(32).toString('hex'))" 526 | ``` 527 | 528 | Run this command for each of the following variables in your `.env` file and paste the result: 529 | 530 | - `JWT_SECRET` 531 | - `JWT_REFRESH_SECRET` 532 | - `EMAIL_ENCRYPTION_KEY` 533 | - `EMAIL_BLIND_INDEX_SECRET` 534 | 535 | **Do not use the same value for different keys.** 536 | 537 | 4. **Configure Google OAuth2 (Optional):** 538 | 539 | To enable Google login functionality, you'll need to: 540 | 541 | a. Go to the [Google Cloud Console](https://console.cloud.google.com/) 542 | 543 | b. Create a new project or select an existing one 544 | 545 | c. Enable the Google+ API 546 | 547 | d. Create OAuth 2.0 credentials (Web application type) 548 | 549 | e. Add your redirect URI: `http://localhost:4000/auth/google/redirect` 550 | 551 | f. Add the following to your `.env` file: 552 | 553 | ```env 554 | GOOGLE_CLIENT_ID=your_google_client_id_here 555 | GOOGLE_CLIENT_SECRET=your_google_client_secret_here 556 | GOOGLE_CALLBACK_URL=http://localhost:4000/auth/google/redirect 557 | ``` 558 | 559 | ## 🔒 Security Features 560 | 561 | ### Authentication Security 562 | 563 | - **JWT with Refresh Tokens**: Secure token-based authentication with automatic refresh 564 | - **Password Security**: Bcrypt hashing with configurable salt rounds 565 | - **OAuth2 Security**: CSRF protection using state parameters in OAuth flows 566 | - **Rate Limiting**: Configurable throttling on sensitive endpoints 567 | 568 | ### Data Protection 569 | 570 | - **Encryption at Rest**: Sensitive data encrypted using AES-256-CBC 571 | - **Blind Indexing**: Secure querying of encrypted data 572 | - **Input Validation**: Comprehensive DTO validation using class-validator 573 | - **SQL Injection Prevention**: MongoDB with Mongoose provides built-in protection 574 | - **Automatic Timestamps**: All models include `createdAt` and `updatedAt` for audit trails 575 | 576 | ### Access Control 577 | 578 | - **Role-Based Authorization**: Complete RBAC implementation with guards 579 | - **Route Protection**: JWT guards on sensitive endpoints 580 | - **Admin Controls**: Separate endpoints for administrative functions 581 | 582 | ## 👨‍💻 Authors 583 | 584 | - **Jerry Lucas** - _Current Maintainer_ - [GitHub](https://github.com/CollatzConjecture) 585 | 586 | ## 📄 License 587 | 588 | This project is licensed under the MIT License - see the [LICENSE](LICENSE) file for details. 589 | 590 | ## 🙏 Acknowledgments 591 | 592 | - **Edwin Caminero** - Inspiration for this project 593 | - Clean Architecture principles by Robert C.
