As your project grows, the way you organize your stories in Storybook becomes crucial for maintainability and scalability. Grouping stories using clear folder structures and consistent naming conventions helps everyone on your team find, update, and reuse components efficiently. Start by mirroring your project's component structure within your src or components directory. For example, if you have folders like Button, Form, and Navigation, place each component's stories in the same folder as the component itself or in a dedicated stories subfolder. Use descriptive and consistent names for your stories and story files. Prefix story titles with the component category, such as "Form/Input" or "Navigation/Sidebar", to create logical groups in the Storybook sidebar. This approach keeps related stories together and makes navigation intuitive, especially as your component library expands.

Consider a design system that includes multiple component categories, such as Inputs, Buttons, and Layout. You might organize your stories like this:

• src/components/Inputs/Input.stories.jsx with the title "Inputs/Input";
• src/components/Buttons/PrimaryButton.stories.jsx with the title "Buttons/PrimaryButton";
• src/components/Layout/Grid.stories.jsx with the title "Layout/Grid".

This structure ensures that, in Storybook's sidebar, all Input components appear under an Inputs group, all Button components under Buttons, and so on. This not only keeps your stories organized but also helps users quickly locate and browse components by type.
