  • 🔌 Compatibility: Use any version of React 15.x+, full CRA compatibility
  • 🔀 Convenience: New addon to dynamically update CSS resources

⚡️ Performance architecture

Storybook 4.1 introduces a key improvement by Norbert de Langen that allows Storybook to run up to 300% faster on cold start and reload.

4.1 splits the preview (user code) and manager (storybook code) into two processes, which improves both performance and react version compatibility.
  1. 🛠 Manager is the enclosing UI for navigating between stories, for addons, and so forth.

🔌 React 15.x+ support

A second benefit of the preview/manager split is the ability to run Storybook with React 15+, which is great news for our React users that collectively download @storybook/react over 3M times each month.

Storybook can live on the bleeding edge without breaking apps that are stuck on older versions.

🔌 create-react-app

Now in Storybook 4.1, you can use all of create-react-app’s features, including Typescript support, without any custom configuration, thanks to Igor Davydkin, Brody McKee, and Chad Fawcett.

🔀 Dynamic CSS

Finally, Storybook 4.1 includes the brand-new CSS Resources addon by Neville Mehta. Now you can easily switch between CSS versions at runtime, which is useful for theming or simply exploring alternative component stylings:
