Component-driven development starts with the parts that carry the product. Buttons, cards, inputs, navigation, empty states, and content blocks become contracts before they become scattered screen implementations.
That shift matters because screens change constantly. Components should become more stable over time. They are where accessibility, token usage, interaction states, and responsive behavior can be solved once.
If every page solves the same UI problem locally, the product is not moving faster. It is duplicating debt.
Start with the API
A good component API describes intent. The consumer should choose a surface, size, or state, not hand over random colors and spacing values.
Build pages from registered parts
The component registry becomes the agreement between design and frontend. If a page needs a card, it uses the card component. If the card cannot support the need, the component is improved deliberately.
Why this works with AI
AI tools become more useful when they can compose existing components instead of inventing UI from scratch. Component-driven development gives them a smaller, safer search space.
Frequently asked questions
It can feel slower at the beginning. The payoff comes when new screens reuse tested decisions instead of reopening them.
