Storybook Error: "Couldn't find story matching 'components-button--page'" - Solved

Ever encountered this frustrating Storybook error? "Couldn't find story matching 'components-button--page'" can leave you scratching your head, wondering where your meticulously crafted story went missing. Fear not, this guide will equip you with the knowledge to conquer this common Storybook hurdle.

The Scenario:

Imagine you're working on a project with a "Button" component. You've created a Storybook entry for it, diligently following best practices. You've even named it components-button--page to reflect its purpose and structure. Yet, when you attempt to navigate to this story, you're met with the dreaded error: "Couldn't find story matching 'components-button--page'".

Your Code (The Culprit?):

// stories/Button.stories.js

import Button from '../components/Button';

export default {
  title: 'Components/Button',
  component: Button,
};

export const Page = () => <Button>Click me!</Button>;

The Root of the Problem:

The error arises because Storybook relies on a specific naming convention to identify and display your stories. Your story name Page doesn't align with the expected structure. Storybook expects stories to be grouped under a specific component name within the title section. In our example, the title is set to Components/Button, meaning Storybook anticipates stories like Components/Button/Default, Components/Button/Primary, etc.

The Solution: Harmonizing Your Story Names:

To fix this, we need to ensure our story name adheres to Storybook's conventions. We can achieve this by modifying our story definition:

// stories/Button.stories.js

import Button from '../components/Button';

export default {
  title: 'Components/Button',
  component: Button,
};

export const Page = () => <Button>Click me!</Button>;

export const PageStory = {
  args: {
    label: 'Click me!',
  },
  render: (args) => <Button {...args} />,
};

Explanation:

• PageStory: We've renamed the story to PageStory to align with Storybook's expectation of stories being named in a way that fits under the title structure.
• args: We've introduced args for better organization and flexibility. This allows us to easily pass props to our component within the story definition.

Now, navigate to the Storybook interface and you'll find your Components/Button/PageStory story, ready to showcase your button in all its glory!

Bonus Tips:

• Document Your Stories: For readability and maintainability, consider adding a brief description for each story using the parameters object:

export const PageStory = {
  args: {
    label: 'Click me!',
  },
  render: (args) => <Button {...args} />,
  parameters: {
    docs: {
      description: {
        story: 'A simple Button component for common interactions.',
      },
    },
  },
};
