react-docgen-typescript-webpack-plugin

Webpack plugin to generate docgen information from Typescript React components.

Installation

Add the package as a development dependency.

$ npm install --save-dev react-docgen-typescript-webpack-plugin

or

$ yarn add --dev react-docgen-typescript-webpack-plugin

Add the plugin to your Webpack configuration.

const path = require("path");
const genDefaultConfig = require("@storybook/react/dist/server/config/defaults/webpack.config.js");
const TSDocgenPlugin = require("react-docgen-typescript-webpack-plugin");

module.exports = (baseConfig, env) => {
  const config = genDefaultConfig(baseConfig);

  config.module.rules.push({
    test: /\.tsx?$/,
    include: path.resolve(__dirname, "../src"),
    loader: require.resolve("ts-loader"),
  });

  config.plugins.push(new TSDocgenPlugin());

  config.resolve.extensions.push(".ts", ".tsx");

  return config;
};

Usage

Storybook Info Plugin

Include the withInfo decorator as normal.

Special Note:

The Storybook Info addon will only attempt to read Docgen information when the story name matches the name of the component. So if you have a component named ColorButton, then you will have to use something like:

storiesOf("...", module).add("ColorButton", ...)

import * as React from "react";
import { storiesOf } from "@storybook/react";
import { withInfo } from "@storybook/addon-info";
import ColorButton from "./ColorButton";

storiesOf("Components", module).add(
  "ColorButton",
  withInfo({ inline: true })(() => (
    <ColorButton color="blue">Color Button</ColorButton>
  )),
);

Experimental

This plugin is mostly a hack job at the moment. It is a work in progress so it is most likely not suitable for production. Pull requests are most welcome.

Limitations

This plugin makes use of the great project: https://github.com/styleguidist/react-docgen-typescript

It is subject to the same limitations. Component docgen information can not be generated for components who are only exported as default. You can work around the issue by exporting the component using a named export.

CURRENT LIMITATION The current implementation seems to have trouble with the compiler option module being set to esnext.

import * as React from "react";

interface ColorButtonProps {
  /** Buttons background color */
  color: "blue" | "green";
}

/** A button with a configurable background color. */
export const ColorButton: React.SFC<ColorButtonProps> = props => (
  <button
    style={{
      padding: 40,
      color: "#eee",
      backgroundColor: props.color,
      fontSize: "2rem",
    }}
  >
    {props.children}
  </button>
);

export default ColorButton;
