Component-Based Design

Component-Based Design is an approach in which interfaces are built using reusable, modular components, such as buttons, navigation bars, and form fields. Each component is designed independently but follows a consistent design system, making it easier to maintain and update the product. Component-based design promotes scalability, consistency, and efficiency in the development process.

Component-based design is the architectural foundation that makes it possible to scale a product without it falling apart visually. Without it, every new page becomes a bespoke decision about what a button should look like — and inconsistency accumulates fast. For founders, investing in component-based design early means your engineering team ships new features faster and your product looks more polished as it grows.

Figma's own UI is entirely built on a component system — every button, input, and panel is a reusable component, which is why their product looks consistent across hundreds of different screens and is easy to update globally.
