Components in isolation

A component explorer lets you build a component outside the full app, rendering it in many states as named stories. Each story fixes a set of props so you can develop a loading state or an error state directly without navigating the real app.

What it unlocks

  • Faster development no need to reach a deep app state to see an edge case.
  • Living documentation stories show every variant for designers and reviewers.
  • A test surface the same stories feed interaction and visual regression tests.

Doing it well

  • Write a story for each meaningful state, including empty and error cases.
  • Keep stories deterministic by mocking data and time.
  • Treat stories as the source of truth that automated tests reuse.

When stories cover the real states, documentation and tests stay in sync with the component.

Key idea

Stories render a component in isolation across its states, serving as development, docs, and a test surface at once.
