Overview

NestJS Clean Architecture with DDD, CQRS, and Event Sourcing is an impressive boilerplate project that stands out for anyone looking to build robust enterprise-level applications. This framework not only embraces the principles of Domain-Driven Design (DDD) but also incorporates Clean Architecture to ensure a maintainable and scalable codebase. With the combination of these architectural patterns, developers can separate concerns effectively while creating applications that are both efficient and easy to manage.

This setup leverages MongoDB through Mongoose, providing a flexible database solution that aligns well with modern application needs. It is particularly useful for developers who desire a strong foundation when embarking on complex projects, offering various methodologies that enhance both performance and scalability.

Features

  • Clean Architecture: Enforces a strict separation of concerns while maintaining clear dependency direction from Infrastructure to Application to Domain.
  • Domain-Driven Design (DDD): Encapsulates pure business logic within Domain Services accessed through Repository Interfaces, aligning with business requirements.
  • CQRS: Efficiently segregates read (Queries) and write (Commands) operations to optimize performance and enhance scalability.
  • Event Sourcing: Implements an event-driven approach that utilizes sagas for orchestrating complex business processes seamlessly.
  • Repository Pattern: Defines clean interfaces in the Domain layer, ensuring a solid implementation within the Infrastructure layer without clutter.
  • JWT Authentication: A secure, token-based authentication system featuring refresh token rotation to maintain user security.
  • Role-Based Access Control (RBAC): Complete implementation for managing permissions and protecting routes based on user roles.
  • Containerized Environment: Simplifies development and deployment with a full Docker and Docker Compose setup, enhancing both local and production environments.
nestjs
Nest

A progressive Node.js framework for building efficient, scalable, and enterprise-grade server-side applications with TypeScript/JavaScript.

docker
Docker

A website that uses Docker for containerization to streamline development, testing, and deployment workflows. This includes features such as containerization of dependencies, automated builds and deployments, and container orchestration to ensure scalability and availability.

eslint
Eslint

ESLint is a linter for JavaScript that analyzes code to detect and report on potential problems and errors, as well as enforce consistent code style and best practices, helping developers to write cleaner, more maintainable code.

typescript
Typescript

TypeScript is a superset of JavaScript, providing optional static typing, classes, interfaces, and other features that help developers write more maintainable and scalable code. TypeScript's static typing system can catch errors at compile-time, making it easier to build and maintain large applications.
