Setting up Storybook for Preact

In my last Storybook post, Getting Started with Storybook for React, I showed you how to install Storybook for React and gave a quick breakdown of what all the pieces were. I suggest giving that a quick read before continuing here.

In this post, I’ll show you how to get React Storybook up and running with Preact. The assumption is that the project you want to add Storybook to already has Preact installed as a dependency.

  1. A temporary step is to first install React, so run npm install react
  2. If you have npx installed, run npx @storybook/cli (most people should have this if you’re on a newer version of node). If not run npm install @storybook/cli -g.
  3. Next from the command line, run getstorybook
  4. This will install all the dependencies you need to run Storybook.
  5. Now let’s uninstall react from our dependencies as we want to use preact!
  6. Next we need to install preact-compat so that Preact will play nicely with Storybook. If you need preact-compat as a dependency for other react libraries, install it to dependencies, npm install preact-compat. Otherwise install it as a dev depency, i.e. npm install preact-compat -D
  7. Almost there!
  8. The last thing we need to do is tell webpack (what Storybook uses under the hood), to use preact-compat. To do this, we need to create a custom webpack configuration file for Storybook. Lucky for us, Storybook supports this out of the box. In the root folder where your package.json file is, there will be a new folder called .storybook. In there it contains files related to Storybook configuration. Create a new file in there called webpack.config.js and paste the following contents and save the file.
module.exports = {
  resolve: {
    extensions: [".js", "jsx"],
    alias: {
      react: "preact-compat",
      "react-dom": "preact-compat"

Note that this is a super bare bones webpack configuration. You can add anything else here you may need just like a regular webpack configuration file.

  1. Storybook will create some demo stories for you found in the root folder of your app at ./stories/index.stories.js
  2. Open this file and remove the React reference and replace it with import { h } from "preact";
  3. All that’s left to do is run npm run storybook and navigate to Storybook in a browser.
