reacty_yew - Generate Yew components from React component via Typescript type definitions

This is a proof of concept for automatically generating Yew components from React components that have Typescript type definitions. Many parts are missing and this likely shouldn't be used in production!

Announcement blog post with a bit more information

Showcase

For the full example see ./examples/bad_button.

Given a React component:

import * as React from "react";

interface BadButtonProps {
  color?: string,
  text: string,
}

const BadButton = (props: BadButtonProps): JSX.Element => {
  return (
    <button
      style={{ backgroundColor: props.color }}
      onClick={() => window.alert("Click!")}
    >
      {props.text}
    </button>
  );

};

export { BadButton };

An invocation of the react_component_mod! macro (takes as input the name of the module to generate, path to the type declarations and the JS global (UMD) that holds the React components) generates a module:

react_component_mod!(
    bad_button;
    types = "../js_package/dist/index.d.ts",
    global = "BadButtonLib"
);

You can directly use the generated component BadButton in a Yew component:

use yew::prelude::*;
use crate::bad_button::BadButton;

// ...
fn view(&self) -> Html {
    html! {
        <div>
            <BadButton text="Actual props" />
        </div>
    }
}
// ...
