SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

The Modular Monolith pattern organizes Go applications into modular, bounded contexts, clarifying ownership, reducing coupling, and improving maintainability by treating modules as cohesive units with explicit boundaries.

Core Features & Use Cases

Defines modules around business domains (bounded contexts) to align code with domain concepts.
Enforces explicit module boundaries and single public APIs to limit cross-module dependencies.
Supports inter-module communication via well-defined interfaces or events, enabling scalable evolution and potential migration to microservices.
Provides guidance on recommended directory structures, module entry points, and migration paths for extracting microservices when appropriate.

Quick Start

Define your modules by business domain, implement a single public API per module, and wire dependencies via injection.

FAQPage Schema

How do I structure a Go application with bounded contexts to reduce coupling?▼

To enforce module boundaries in a Go monolith, define modules around business domains and expose a single public API per module. Wire dependencies via injection to limit coupling and prepare for potential future microservices extraction.

What is the best way to handle inter-module communication in a Go modular monolith?▼

Inter-module communication in a modular monolith is best handled through well-defined interfaces or event-based mechanisms. This approach maintains strict module boundaries while enabling scalable evolution and migration to microservices.

Can I use domain-driven design to refactor a large Go monolith into modules?▼

Domain-driven design can refactor a large Go monolith by defining bounded-context modules around business domains. This clarifies ownership, reduces coupling, and treats modules as cohesive units with explicit boundaries for better maintainability.

How does a modular monolith architecture help with migrating to microservices in Go?▼

A modular monolith architecture aids Go microservices migration by enforcing explicit module boundaries and single public APIs. Inter-module communication via interfaces or events allows individual modules to be extracted into separate services when appropriate.

When should I not use the modular monolith pattern for my Go application?▼

The modular monolith pattern may not suit small Go applications with minimal domain complexity, as the overhead of defining bounded contexts and explicit module APIs outweighs maintainability benefits. It is best applied to large monolith refactors or complex domain-driven projects.
