typescript

Type:

{
  check?: boolean;
  checkOptions?: CheckOptions;
  reactDocgen?: 'react-docgen' | 'react-docgen-typescript' | false;
  reactDocgenTypescriptOptions?: ReactDocgenTypescriptOptions;
  skipCompiler?: boolean;
}

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-webpack5)
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-webpack5)
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': if @storybook/react is installed

Configures which library, if any, Storybook uses to parse React components, react-docgen or react-docgen-typescript. Set to false to disable parsing React components. react-docgen-typescript invokes the TypeScript compiler, which makes it slow but generally accurate. react-docgen performs its own analysis, which is much faster but incomplete.

.storybook/main.ts

// Replace your-framework with the framework you are using (e.g., react-webpack5, react-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: {
    reactDocgen: 'react-docgen',
  },
};
 
export default config;

`reactDocgenTypescriptOptions`

Type: ReactDocgenTypescriptOptions

Configures the options to pass to react-docgen-typescript-plugin if react-docgen-typescript is enabled. See docs for available options.

.storybook/main.ts

// Replace your-framework with the framework you are using (e.g., react-webpack5, react-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: {
    reactDocgen: 'react-docgen-typescript',
    reactDocgenTypescriptOptions: {
      shouldExtractLiteralValuesFromEnum: true,
      // 👇 Default prop filter, which excludes props from node_modules
      propFilter: (prop) => (prop.parent ? !/node_modules/.test(prop.parent.fileName) : true),
    },
  },
};
 
export default config;

`skipCompiler`

Type: boolean

Disable parsing of TypeScript files through the compiler, which is used for Webpack5.

.storybook/main.ts

// Replace your-framework with the framework you are using (e.g., react-webpack5)
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: {
    skipCompiler: true,
  },
};
 
export default config;
