Component testing with Vitest integration

This week we have Jeppe Reinhold, a core contributor to Storybook working at Chromatic. Jeppe shares how Storybook has evolved from a slow, complex tool to a fast, modern development environment through major architectural changes like Vite integration, ESM migration, and dependency reduction. We talk about the Component Story Format evolution, framework agnosticism challenges, local testing improvements with vitest integration, and how Storybook is integrating with AI and LLMs through MCP servers to help coding agents understand and use component libraries.
