import React from "react";
import ReactDOM from "react-dom";
import { storiesOf, getStorybook } from "@storybook/react";

let stories = null;

function renderStory({ kind, story }) {
  const root = document.getElementById("root");

  ReactDOM.unmountComponentAtNode(root);
  ReactDOM.render(stories[kind][story](), root);
}

storiesOf("All", module).add("Stories", () => {
  if (!stories) {
    stories = {};
    getStorybook().forEach(kind => {
      stories[kind.kind] = {};
      kind.stories.forEach(story => {
        stories[kind.kind][story.name] = story.render;
      });
    });
  }
  window.renderStory = renderStory;
  window.getStorybook = getStorybook;
  return <div />;
});
