Storybook

Create a monorepo

If you don't have an existing project, use create-turbo to create a new monorepo:

npx create-turbo@latest

Create a directory for the app

You'll need a directory for the Storybook application:

mkdir apps/storybook
cd apps/storybook

Add the Storybook application

In the apps/storybook directory, initialize a new Storybook application:

npx storybook@latest init

Follow the prompts to create an application. For the rest of this guide, we'll assume React and TypeScript.

Add your UI kit to Storybook

Now, install your UI package into Storybook.

npm install @repo/ui --workspace=storybook

Set up a story for your Button component

Delete the stories and components found in src/stories that were created by the Storybook scaffolding tool. You will be making your own.

As an example, here is a story for the Button component from @repo/ui/button.

import type { Meta, StoryObj } from '@storybook/react';
import { Button } from '@repo/ui/button';
 
const meta = {
  title: 'Example/Button',
  component: Button,
  tags: ['autodocs'],
} satisfies Meta<typeof Button>;
 
export default meta;
type Story = StoryObj<typeof meta>;
 
export const Primary: Story = {
  args: {
    appName: 'Button',
    children: 'I am a primary button.',
  },
};

Align scripts to your tasks

Last, integrate the new Storybook application into your Turborepo:

{
  "scripts": {
    "dev": "storybook dev -p 6006", 
    "build": "storybook build"
  }
}

These scripts will now run with the turbo dev and turbo build tasks in your turbo.json.

To ensure file outputs are cached when you run build, add storybook-static to the outputs of your turbo.json build task:

{
  "tasks": {
    "build": {
      "outputs": [
        ".next/**",
        "!.next/cache/**"
+       "storybook-static/**"
      ]
    }
  }
}

+ storybook-static

Re-configure Storybook sources

In .storybook/main.ts, change the stories paths in config to the directories you'd like to capture. For instance, if you'd like to write stories in the UI package:

 
const config = {
  stories: [
-   "../src/**/*.mdx",
-   "../src/**/*.stories.@(js|jsx|mjs|ts|tsx)"],
+   "../../../packages/ui/src/**/*.stories.@(js|jsx|mjs|ts|tsx)",
};

Move story files to the UI package

Following along with the guide above, move the ./apps/storybook/src/stories/Button.stories.tsx file to ./packages/ui/src/Button.stories.tsx.

Update components imports so that they reference the now co-located modules. For instance, in the story's imports:

- import { Button } from "@repo/ui/button";
+ import { Button } from "./button";

You'll also need to install any Storybook packages required for writing stories. For example, moving the story from above would require that you install @storybook/react into your @repo/ui package.

npm install @storybook/react --workspace=@repo/ui --save-dev

Configure caching

Because stories are now in the UI package, changes to those stories can cause cache misses for any builds that depend on your UI package. However, changing a story doesn't mean your production applications should miss cache.

To prevent this, exclude stories from the inputs to your build task in your root turbo.json. You'll also need to create a build:storybook task, which you'll need in a moment:

{
  "tasks": {
    "build": {
      "dependsOn": ["^build"],
      "inputs": ["$TURBO_DEFAULT$", "!**/*.stories.{tsx,jsx,mdx}"], 
      "outputs": [".next/**", "!.next/cache/**"]
    },
    "build:storybook": {} 
  }
}

Additionally, create a Package Configuration in the storybook application so stories are accounted for in building the Storybook application, specifically:

{
  "extends": ["//"],
  "tasks": {
    "build:storybook": {
      "dependsOn": ["^build:storybook"],
      "outputs": ["storybook-static/**"]
    }
  }
}

Rename the build script

Last, make sure your script to build Storybook uses the configuration we just wrote by renaming it to the name of the task:

{
  "scripts": {
    "dev": "storybook dev -p 6006",
    "build:storybook": "storybook build"
  }
}

The script that was once "build" is now "build:storybook" to ensure the stories are included in hashes for caching.

Verify your configuration

To ensure your setup is correct:

1. Run turbo build:storybook build. You should see cache misses.
2. Run turbo build:storybook build again. You should see all cache hits.
3. Make a code change to a story in your @repo/ui package.
4. Run turbo build:storybook build again. You should only see a cache miss for the Storybook application. All others should hit cache.
