How I built a React design system in Storybook

When I joined my first big React project, I didn’t think twice about copy-pasting components. Need a model? Grab it from Project A. Dropdown? Probably lived somewhere in Project B, or maybe it was C. It worked — until it didn’t.

Over time, maintaining UI across different projects became a total mess. Components had random props like isOpenLegacy, styles clashed, and onboarding juniors meant 30-minute calls explaining “what to use and what to ignore.” This got me thinking — “There’s surely a better way of doing this.” And that’s when I found Storybook for React. What started as my attempt to organize a few components ended up as building a full-fledged React Design System. Here’s how you can build your own React Design System.

What is a React design system?

A React design system is a structured, documented, and reusable collection of UI components, patterns, and tokens. Mine started small with just a few reusable React components. As I used it, it bloomed into an actual component library in React, with folders, themes, documentation, and testing. And what made it work? Storybook setup for React.

Discovering Storybook for React

I still remember running npx sb init for the first time. Within seconds, I had a playground for my UI. No more spinning up the whole app to test a hover state. No more breaking things to tweak styles.

What Storybook gave me:

• An isolated space to build UI components in React apps
• Live previews with props that I could tweak
• A visual way for others to explore components
• A faster onboarding experience for new devs
• Interactive docs — not just README files

It felt like having my own mini Design System portal. I soon realized that it was more than just a playground. It fixed two of my biggest problems of reusability and visual testing. That’s what really kept me going with the design system.

My first real component: The Accordion

The moment I realized I was creating something helpful was when I transformed a messy, hardcoded Accordion into a clean, flexible, and documented component.

Here’s the actual Accordion that kicked it all off: ……Read More
