SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Structure large apps with clear module boundaries inside a single deployment.

Core Features & Use Cases

  • Module-based architecture with explicit api/internal separation and an integration layer.
  • Event-based communication and a shared kernel to enable safe cross-module collaboration.
  • Scales from small to mid-sized teams (3-10 developers) and includes a migration path from monolith to microservices.

Quick Start

Create a Module folder structure with /modules/[name]/api, /modules/[name]/internal, and a module.ts, then wire modules in a composition root.

FAQPage Schema
What is a modular monolith architecture and when should I use it?▼

A modular monolith structures large applications with clear module boundaries inside a single deployment. It suits mid-sized projects with 3-10 developers seeking monolith simplicity combined with microservice evolution capabilities.

How do I structure modules in a modular monolith?▼

Create a module folder structure with /modules/[name]/api, /modules/[name]/internal, and a module.ts file, then wire modules in a composition root to enforce explicit interfaces and architectural rules.

How do modules communicate in a modular monolith without tight coupling?▼

Modules communicate using event-based messaging and a shared kernel. This integration layer enables safe cross-module collaboration while maintaining strict module ownership and explicit API boundaries.

Modular monolith vs microservices: which approach is best for scaling a mid-sized team?▼

A modular monolith is best for mid-sized teams of 3-10 developers needing a balance between simplicity and flexibility. It provides a defined migration path to microservices if scaling requirements eventually outgrow a single deployment.

Can I migrate my modular monolith to microservices later?▼

Yes, a modular monolith includes a defined migration path to microservices. By enforcing module ownership, explicit interfaces, and event-based communication early, you can extract bounded contexts into separate deployments when scale demands it.
