I didn't build Spiral UI by designing finished components first. Instead, I broke every component down into the smallest building blocks it was made of, then built those pieces individually before assembling them into larger components.

Take an input field, for example. It isn't a single component it's a label, the field itself, and a helper text. Each of those exists as its own reusable component, which are then combined to create the complete input field. I applied this same approach throughout the entire design system.

It's slower than simply drawing the finished component, but it creates a much stronger foundation. Every component is built from the same set of reusable pieces, which keeps the system consistent as it grows.

This approach paid off in the long run. Because labels and helper text were already standalone components, whenever I designed another component that required them I didn't have to recreate them. I simply reused the existing components. That meant improvements made to a label or helper text automatically benefited every component that depended on them, reducing duplication, making maintenance easier, and ensuring consistency across more than 6,000 components.

This philosophy extends across the entire design system. Design tokens for color, typography, spacing, border radius, shadows, and effects form the foundation of every component, while responsive behavior and light & dark mode support are built into the system from the start rather than added later. As the library continued to grow, having this modular foundation made it significantly easier to scale without introducing inconsistencies.
