nestjs-modular-monolith

To architect a modular monolith in NestJS, you define bounded contexts and domain modules with explicit interfaces. This approach uses DDD and Clean Architecture to ensure clear module boundaries and maintainability.

Event-driven module communication is the recommended way to decouple NestJS domain modules. By applying this pattern within your modular monolith, modules interact through explicit events rather than direct dependencies.

Yes, a NestJS modular monolith works effectively within an NX-based monorepo. This setup supports module boundary reviews and strategy guidance, allowing you to manage enterprise backend design and scalability across the monorepo.

Planning a monolith-to-microservices evolution path involves structuring NestJS modules with explicit interfaces and optional CQRS integration. This modular monolith strategy allows you to gradually extract bounded contexts into independent microservices.

You should apply CQRS in a NestJS modular monolith when you need to separate read and write operations for complex domain modules. This optional integration helps balance modularity and scalability within bounded contexts.

NestJS monoliths face maintainability issues when lacking clear module boundaries and bounded contexts. Applying a modular monolith architecture with explicit interfaces and event-driven communication resolves these scalability and dependency problems.
