This chapter was the focus of a tool called Storybook. Storybook provides React developers with a sandboxed environment that makes it easy to develop React components on their own. This can be difficult when the only environment you have is the application that you're working on. Storybook provides a level of development isolation.
First, you learned how to install the global Storybook command-line utility and how to use this utility to get Storybook set up in your create-react-app projects. Next, you learned how to write stories that show different perspectives of a component.
Then, you learned that a good portion of Storybook functionality comes from add-ons. You learned that Actions help with logging and that links provide a mechanism for navigation beyond the default. You also learned how to write documentation for React components using Storybook. We closed the chapter with a look at building static Storybook content.
In the next chapter, you'll explore the React tooling available...
