nestjs-microservice-boilerplate-api
NestJS Microservice Boilerplate API is an enterprise-grade, production-ready boilerplate for building scalable NestJS microservices. It implements a pragmatic architecture combining Clean Architecture, Domain-Driven Design, and Hexagonal Architecture, keeping business logic independent of frameworks and databases. Key features include MongoDB and PostgreSQL CRUD with generic repository patterns, Docker support, Husky for git hooks, Swagger documentation, authentication and authorization, centralized error handling, and reusable services for secrets, HTTP, and logs. The project enforces strict layer communication rules with entities, use cases, and repository interfaces in the core layer, and NestJS controllers plus database implementations in the modules and infrastructure layers. Designed to be powerful enough for enterprise applications yet simple enough for any developer to understand, it enables quick bootstrapping of maintainable microservice APIs with Node.js 22 and TypeScript 5.9.3.
