react-docgen cannot extract comments with hermes-parser

[Brianzchen]

Component comment blocks as well as proptype comments cannot be extracted with react docgen when using babel hermes-parser plugin https://www.npmjs.com/package/babel-plugin-syntax-hermes-parser. This parser is essential when running an application with flow

This issue explains it a bit more facebook/hermes#1098. Would it be possible to improve the default handlers to support this?

Interesting, first time I heard about this. I will check, but I'm not confident I can do something from our side.

I've managed to write an albeit hacky solution to extract component and prop descriptions but now I'm struggling to figure out how to jump cross components to find the spread objects and their descriptions. Can you offer some advice here?

import { type B } from '../B';

type A = {
 ...B
}

Sadly it seems there's no documentation on handlers (or much else) so I've just been logging the object structure + trying to decipher the default handlers to try get what I need.

I've just made my component type definition more complicated which has unfortunately broken my own plugin.. The ones written in this lib to handle all other docs still works as expected. Would be so great if they worked on comments 😢

@danez did you get a chance to look into it?
