ArgTypes

Watch a video tutorial on the Storybook channel

The ArgTypes block can be used to show a static table of arg types for a given component, as a way to document its interface.

If you’re looking for a dynamic table that shows a story’s current arg values for a story and supports users changing them, see the Controls block instead.

Configuring with props and parameters

ℹ️ Like most blocks, the ArgTypes block is configured with props in MDX. Many of those props derive their default value from a corresponding parameter in the block's namespace, parameters.docs.argTypes.

The following exclude configurations are equivalent:

The example above applied the parameter at the component (or meta) level, but it could also be applied at the project or story level.

exclude

Type: string[] | RegExp

Default: parameters.docs.argTypes.exclude

Specifies which arg types to exclude from the args table. Any arg types whose names match the regex or are part of the array will be left out.

include

Type: string[] | RegExp

Default: parameters.docs.argTypes.include

Specifies which arg types to include in the args table. Any arg types whose names don’t match the regex or are not part of the array will be left out.

of

Type: Story export or CSF file exports

Specifies which story to get the arg types from. If a CSF file exports is provided, it will use the primary (first) story in the file.

sort

Type: 'none' | 'alpha' | 'requiredFirst'

Default: parameters.docs.argTypes.sort or 'none'

Specifies how the arg types are sorted.

  • none: Unsorted, displayed in the same order the arg types are processed in
  • alpha: Sorted alphabetically, by the arg type's name
  • requiredFirst: Same as alpha, with any required arg types displayed first
