Modular Monolith

Imagine:

React Application │ ├── Expenses ├── Loans ├── Reports ├── Dashboard └── Users

Each feature has boundaries.

Expenses

├── components

├── hooks

├── api

└── types

Loans

├── components

├── hooks

├── api

└── types

But everything still builds and deploys together.

That's essentially a: modular Monolith
And this is often a very good default architecture.

because clear boundaries

• feature ownership

• easier testing

• easier development

• simpler deployment

• less infrastructure complexity

without immediately introducing Micro Frontends.
