Storybook: Addon-docs: Flowtypes & Typescript?

[josias-r]

Is your feature request related to a problem? Please describe.
Since react-docgen now supports flowtypes and typescript out of the box, from my understanding, all other typescript docgen methods are deprecated?

But from the following code PropRow.tsx I think there is no flowtype handling yet to supersede the current alternatives.

Describe the solution you'd like
the babel react-docgen plugin should get an update soon with the latest react-docgen version, therefore PropRow.tsx should handle typescript props.

I just didn't find anything regarding typescirpt / flowtype prop handling, which is why I created this issue, to make sure it's beeing tracked 😁

still active.

+1 for inferring props from flow types

I think this is related: https://github.com/storybookjs/storybook/issues/6640 and https://github.com/storybookjs/storybook/issues/6640#issuecomment-527529040

Hello @josias-r,
1 Are the types simply not detected by docgen and we need to update it? or
2 Are flow types not displaying correctly inside of addon-docs?

Hi @elevatebart
2.
For now I think the babel react docgen plugin still needs to recieve the docgen update.
When it finally gets updated docgen will generate a flowType property with flow and typescript props inside it.
At this point, this flowType property is not handled by the the addon-docs. Addon-docs is currently ignoring the flowType property.

@elevatebart @josias-r for a little more context, i opened this #8115 issue a bit ago. Looks like some flow types (like primitives) are working by side effect, but like in my example "enums" or more complex types aren't supported

react-docgen support for TypeScript is currently very unstable. I wouldn't recommend using it.

TS & FlowType basic support is available with beta.3

Improvement for TS should be available for the official release of 5.3

Forgot this issue was already created, and filed a duplicate at #9837, where I'm currently tracking my progress. Closing this!
