Definition:Modular Monolith
A Modular Monolith is a software design pattern where an entire application lives in a single codebase structured into strict, decoupled domain modules.
Detailed Technical Explanation
Business Perspective
Modular monoliths provide the optimal balance of developer velocity, low cloud hosting costs, and clean code organization for startups and growing enterprises.
Technical Perspective
Modules communicate via in-memory TypeScript interfaces rather than remote HTTP inter-service network calls.
Real-World Example
A custom ERP codebase organized into `/finance`, `/inventory`, and `/hrms` modules running on a single Node.js process.
Common Architectural Mistakes
- ✗Tightly Coupled Imports: Bypassing internal module boundary interfaces to mutate private domain state directly.

Frequently Asked Questions
Why do senior architects favor modular monoliths?
They eliminate network latency and deployment complexity while allowing straightforward microservice extraction later if needed.
