Configures how Storybook handles TypeScript files.

`check`

Type: boolean

Optionally run fork-ts-checker-webpack-plugin. Note that because this uses a Webpack plugin, it is only available when using the Webpack builder.

.storybook/main.ts

// Replace your-framework with the framework you are using (e.g., react-webpack5, vue3-vite)
import type { StorybookConfig } from '@storybook/your-framework';
 
const config: StorybookConfig = {
  framework: '@storybook/your-framework',
  stories: ['../src/**/*.mdx', '../src/**/*.stories.@(js|jsx|mjs|ts|tsx)'],
  typescript: {
    check: true,
  },
};
 
export default config;

`checkOptions`

Type: CheckOptions

Options to pass to fork-ts-checker-webpack-plugin, if enabled. See docs for available options.

.storybook/main.ts

// Replace your-framework with the framework you are using (e.g., react-webpack5, vue3-vite)
import type { StorybookConfig } from '@storybook/your-framework';
 
const config: StorybookConfig = {
  framework: '@storybook/your-framework',
  stories: ['../src/**/*.mdx', '../src/**/*.stories.@(js|jsx|mjs|ts|tsx)'],
  typescript: {
    check: true,
    checkOptions: {
      eslint: true,
    },
  },
};
 
export default config;

`reactDocgen`

Type: 'react-docgen' | 'react-docgen-typescript' | false

Default:

false: if @storybook/react is not installed
'react-docgen-typescript': if @storybook/react and typescript are installed
'react-docgen': if @storybook/react is installed

Only available for React Storybook projects. Configure which library, if any, Storybook uses to parse React components, react-docgen or react-docgen-typescript. Set to false to disable parsing React components.

  framework: '@storybook/your-framework',

  },
};

      propFilter: (prop) => (prop.parent ? !/node_modules/.test(prop.parent.fileName) : true),
    },
  },
};
