Component Architecture That Scales

Strong component architecture makes code easier to change than to read. The trick is to keep boundaries obvious and responsibilities narrow.

Build from Smaller Units

Start with focused components that each do one thing well. Smaller pieces are easier to test, reuse, and replace.

Separate Data From Presentation

Containers can handle fetching and orchestration while visual components stay focused on rendering.

Prefer Explicit Props

Clear prop names communicate intent better than hidden assumptions. If a component needs too many props, it may be trying to do too much.

Keep Shared Patterns Consistent

Buttons, inputs, cards, and overlays should follow the same internal conventions across the app.

Watch for Leakage

If a component depends on details from another layer, the abstraction is probably too weak.

A Useful Rule

When in doubt, optimize for easy replacement. Components that can be swapped without touching the rest of the app usually age well.
