Research direction
Reproduce the issue in the linked playground using the two component examples and compare the extracted results for Props and Readonly. The fix is complete when the Readonly result retains the prop description and tsType information shown for Props.
Written by the indexing model from the issue text.
Description
You can paste the code below in the playground and see that description and tsType are lost.
interface Props {
/** The name to greet */
name: string
}
/**
* Hello world component
*/
const MyComponent = ({name = 'world'}: Props) => {
return <div />;
}
/**
* Hello world Readonly
*/
const MyReadonlyPropsComponent = ({name = 'world'}: Readonly<Props>)=> {
return <div />;
}
I noticed this behaviour while digging through an issue that appeared after the latest Storybook's major update, which uses this package by default to extract information from the components.
