View layer support

Docs supports all view layers that Storybook supports except for React Native (currently). There are some view-layer specific features as well. This chart captures the current state of support

Notes:

• # denotes planned/WIP support

Installation

First add the package. Make sure that the versions for your @storybook/* packages match:

yarn add -D @storybook/addon-docs

The add the following to your .storybook/presets.js exports:

module.exports = ['@storybook/addon-docs/react/preset'];

If you're not using react, replace it with your framework of choice corresponding to the Storybook package name, e.g. angular for @storybook/angular etc.

Preset options

The addon-docs preset has a few configuration options that can be used to configure its babel/webpack loading behavior. Here's an example of how to use the preset with options:

module.exports = [
  {
    name: '@storybook/addon-docs/react/preset',
    options: {
      configureJSX: true,
      babelOptions: {},
      sourceLoaderOptions: null,
    },
  },
];

The configureJsx option is useful when you're writing your docs in MDX and your project's babel config isn't already set up to handle JSX files. babelOptions is a way to further configure the babel processor when you're using configureJSX.

sourceLoaderOptions is an object for configuring @storybook/source-loader. When set to null it tells docs not to run the source-loader at all, which can be used as an optimization, or if you're already using source-loader in your webpack.config.js.

Manual configuration

If you don't want to use the preset, and prefer to configure "the long way", first register the addon in .storybook/addons.js:

import '@storybook/addon-docs/register';

Then configure Storybook's webpack loader in .storybook/webpack.config.js to understand MDX story files and annotate TS/JS story files with source code using source-loader:

const createCompiler = require('@storybook/addon-docs/mdx-compiler-plugin');

module.exports = async ({ config }) => {
  config.module.rules.push({
    test: /\.(stories|story)\.mdx$/,
    use: [
      {
        loader: 'babel-loader',
        // may or may not need this line depending on your app's setup
        plugins: ['@babel/plugin-transform-react-jsx'],
      },
      {
        loader: '@mdx-js/loader',
        options: {
          compilers: [createCompiler({})],
        },
      },
    ],
  });
  config.module.rules.push({
    test: /\.(stories|story)\.[tj]sx?$/,
    loader: require.resolve('@storybook/source-loader'),
    exclude: [/node_modules/],
    enforce: 'pre',
  });
  return config;
};
