ATOMIC DESIGN: FROM UI COMPOSITION TO REAL-WORLD APPLICATIONS

Summary from the TLDR Design newsletter

Atomic Design effectively organizes UI components into atoms, molecules, and organisms, but it should serve as a composition pattern rather than a complete application architecture. When components accumulate business logic, data fetching, and state management, they become difficult to test and maintain, turning the UI into a monolith. The proposed solution separates UI composition (where Atomic Design lives) from application architecture through a feature-driven organization, with a strict rule that prevents UI components from importing domain logic or accessing business state.
