Modular Monolith Frontend

A Modular Monolith is a code organization pattern where a single application is strictly divided into domain-based modules.

What it is

Section titled “What it is”

The entire application is deployed as a single unit, but the code is strictly organized based on Domain-Driven Design (DDD) principles. It enforces boundaries within a single repository.

When it works well

Section titled “When it works well”
  • Growing teams: Allows teams to work on different domains without stepping on each other.
  • Maintainability: Clear boundaries make the codebase easier to reason about compared to a “spaghetti” monolith.
  • Simplicity: No infrastructure overhead of microservices or micro frontends.

When it becomes problematic

Section titled “When it becomes problematic”
  • Deployment coupling: Still requires a full rebuild and redeploy for any change.
  • Resource limits: Large monoliths can eventually hit build time and memory limits.

Technical Complexity

Section titled “Technical Complexity”

Medium. Often implemented using workspace tools like Nx or Turborepo to enforce module boundaries.
