Nestify is a monorepo that provides a framework for building NestJS applications with a sample order management system demonstrating its use. The repository separates reusable framework capabilities (in packages/) from application-specific code (in apps/api/). The framework provides building blocks for DDD-style NestJS APIs including database integrations (Kysely, ClickHouse), messaging (BullMQ, NATS), caching (Redis/Redisson), observability, resilience patterns, and DDD primitives. The sample application implements an order management system with REST endpoints, PostgreSQL database, Redis integration, and Clean Architecture layers using CQRS pattern. The framework emphasizes separation of concerns, with explicit rules against placing business logic in framework packages.
