Frontend complexity usually grows faster than teams expect. The fix is not more abstractions, but clearer boundaries.
Organize by product capabilities
We structure code by capabilities instead of by technical layer. Each capability owns its UI, state, tests, and integration points.
This reduces cross-team coupling and makes changes easier to reason about.
Treat the design system as infrastructure
A design system is a product dependency, not a style library. We version components, define migration paths, and enforce usage through linting and visual regression checks.
This keeps brand and interaction quality consistent while teams ship independently.
Keep page composition thin
Pages should compose capabilities, not implement business logic directly. We keep heavy logic close to domain modules and expose narrow interfaces to page-level code.
This improves testability and prevents duplicated behavior.
Final takeaway
Scale is sustainable when architecture mirrors team ownership. Clear capability boundaries and disciplined UI infrastructure are what keep velocity high over time.
