@storybook/nextjs
Advanced tools
@storybook/nextjs is a Storybook preset for Next.js applications. It allows developers to build and test UI components in isolation within a Next.js environment. This package integrates Storybook seamlessly with Next.js, providing a powerful toolset for developing, testing, and documenting UI components.
Component Isolation
Allows developers to create stories for individual components, enabling them to be rendered in isolation. This helps in testing and developing components independently of the application.
import { storiesOf } from '@storybook/react';
import MyComponent from '../components/MyComponent';
storiesOf('MyComponent', module)
.add('default', () => <MyComponent />)
.add('with props', () => <MyComponent prop1="value1" prop2="value2" />);Next.js Routing
Supports Next.js routing in Storybook stories, allowing developers to simulate different routes and test components/pages as they would appear in the actual application.
import { storiesOf } from '@storybook/react';
import { RouterContext } from 'next/dist/shared/lib/router-context';
import MyPage from '../pages/mypage';
storiesOf('MyPage', module)
.addDecorator((story) => (
<RouterContext.Provider value={{ pathname: '/mypage', query: {} }}>
{story()}
</RouterContext.Provider>
))
.add('default', () => <MyPage />);Static File Serving
Enables serving static files such as images, stylesheets, and other assets within Storybook, mimicking the Next.js static file serving capabilities.
import { storiesOf } from '@storybook/react';
import ImageComponent from '../components/ImageComponent';
storiesOf('ImageComponent', module)
.add('default', () => <ImageComponent src="/static/image.png" />);@storybook/react is a Storybook preset for React applications. It provides similar functionality for building and testing UI components in isolation but does not include specific integrations for Next.js features like routing and static file serving.
next-storybook is another package that integrates Storybook with Next.js. It offers similar functionalities to @storybook/nextjs, such as support for Next.js routing and static file serving, but may have different configuration and setup processes.
react-cosmos is a tool for developing and testing React components in isolation. While it provides similar component isolation capabilities, it does not offer the same level of integration with Next.js as @storybook/nextjs.

Follow the prompts after running this command in your Next.js project's root directory:
npx storybook@next init
More on getting started with Storybook
This framework is designed to work with Storybook 7. If you’re not already using v7, upgrade with this command:
npx storybook@next upgrade --prerelease
When running the upgrade command above, you should get a prompt asking you to migrate to @storybook/nextjs, which should handle everything for you. In case that auto-migration does not work for your project, refer to the manual migration below.
Install the framework:
yarn add --dev @storybook/nextjs@next
Update your main.js to change the framework property:
// .storybook/main.js
export default {
// ...
framework: {
// name: '@storybook/react-webpack5', // Remove this
name: '@storybook/nextjs', // Add this
options: {},
},
};
If you were using Storybook plugins to integrate with Next.js, those are no longer necessary when using this framework and can be removed:
// .storybook/main.js
export default {
// ...
addons: [
// ...
// These can both be removed
// 'storybook-addon-next',
// 'storybook-addon-next-router',
],
};
You can be pass an options object for addional configuration if needed.
For example:
// .storybook/main.js
import * as path from 'path';
export default {
// ...
framework: {
name: '@storybook/nextjs',
options: {
nextConfigPath: path.resolve(__dirname, '../next.config.js'),
},
},
};
nextConfigPath: The absolute path to the next.config.jsnext/image is notoriously difficult to get working with Storybook. This framework allows you to use Next.js's Image component with no configuration!
Local images work just fine! Keep in mind that this feature was only added in Next.js v11.
import Image from 'next/image';
import profilePic from '../public/me.png';
function Home() {
return (
<>
<h1>My Homepage</h1>
<Image
src={profilePic}
alt="Picture of the author"
// width={500} automatically provided
// height={500} automatically provided
// blurDataURL="../public/me.png" set to equal the image itself (for this framework)
// placeholder="blur" // Optional blur-up while loading
/>
<p>Welcome to my homepage!</p>
</>
);
}
Remote images also work just fine!
import Image from 'next/image';
export default function Home() {
return (
<>
<h1>My Homepage</h1>
<Image src="/me.png" alt="Picture of the author" width={500} height={500} />
<p>Welcome to my homepage!</p>
</>
);
}
This format is not supported by this framework yet. Feel free to open up an issue if this is something you want to see.
@next/font is partially supported in Storybook. The packages @next/font/google and @next/font/local are supported.
You don't have to do anything. @next/font/google is supported out of the box.
For local fonts you have to define the src property. The path is relative to the directory where the font loader function is called.
If the following component defines your localFont like this:
// src/components/MyComponent.js
import localFont from '@next/font/local';
const localRubikStorm = localFont({ src: './fonts/RubikStorm-Regular.ttf' });
You have to tell Storybook where the fonts directory is located. The from value is relative to the .storybook directory. The to value is relative to the execution context of Storybook. Very likely it is the root of your project.
// .storybook/main.js
export default {
...
"staticDirs": [
{
from: '../src/components/fonts',
to: 'src/components/fonts'
}
],
}
The following features are not supported (yet). Support for these features might be planned for the future:
Next.js's router is automatically stubbed for you so that when the router is interacted with, all of its interactions are automatically logged to the Actions ctions panel if you have the Storybook actions addon.
When using Next.js 13+, you should only use
next/routerin thepagesdirectory. In theappdirectory, it is necessary to usenext/navigation.
Per-story overrides can be done by adding a nextjs.router property onto the story parameters. The framework will shallowly merge whatever you put here into the router.
// SomeComponentThatUsesTheRouter.stories.js
import SomeComponentThatUsesTheRouter from './SomeComponentThatUsesTheRouter';
export default {
component: SomeComponentThatUsesTheRouter,
};
// If you have the actions addon,
// you can interact with the links and see the route change events there
export const Example = {
parameters: {
nextjs: {
router: {
path: '/profile/[id]',
asPath: '/profile/1',
query: {
id: '1',
},
},
},
},
};
Global defaults can be set in preview.js and will be shallowly merged with the default router.
// .storybook/preview.js
export const parameters = {
nextjs: {
router: {
path: '/some-default-path',
asPath: '/some-default-path',
query: {},
},
},
};
The default values on the stubbed router are as follows (see globals for more details on how globals work)
const defaultRouter = {
push(...args) {
action('nextRouter.push')(...args);
return Promise.resolve(true);
},
replace(...args) {
action('nextRouter.replace')(...args);
return Promise.resolve(true);
},
reload(...args) {
action('nextRouter.reload')(...args);
},
back(...args) {
action('nextRouter.back')(...args);
},
forward() {
action('nextRouter.forward')();
},
prefetch(...args) {
action('nextRouter.prefetch')(...args);
return Promise.resolve();
},
beforePopState(...args) {
action('nextRouter.beforePopState')(...args);
},
events: {
on(...args) {
action('nextRouter.events.on')(...args);
},
off(...args) {
action('nextRouter.events.off')(...args);
},
emit(...args) {
action('nextRouter.events.emit')(...args);
},
},
// The locale should be configured [globally](https://storybook.js.org/docs/react/essentials/toolbars-and-globals#globals)
locale: globals?.locale,
asPath: '/',
basePath: '/',
isFallback: false,
isLocaleDomain: false,
isReady: true,
isPreview: false,
route: '/',
pathname: '/',
query: {},
};
If you override a function, you lose the automatic actions integration and have to build it out yourself.
// .storybook/preview.js
export const parameters = {
nextjs: {
router: {
push() {
// The default implementation that logs the action into the Actions panel is lost
},
},
},
};
Doing this yourself looks something like this (make sure you install the @storybook/addon-actions package):
// .storybook/preview.js
import { action } from '@storybook/addon-actions';
export const parameters = {
nextjs: {
router: {
push(...args) {
// Custom logic can go here
// This logs to the Actions panel
action('nextRouter.push')(...args);
// Return whatever you want here
return Promise.resolve(true);
},
},
},
};
Please note that next/navigation can only be used in components/pages in the
appdirectory of Next.js 13+.
nextjs.appDirectory to trueIf your story imports components that use next/navigation, you need to set the parameter nextjs.appDirectory to true in your Story:
// SomeComponentThatUsesTheRouter.stories.js
import SomeComponentThatUsesTheNavigation from './SomeComponentThatUsesTheNavigation';
export default {
component: SomeComponentThatUsesTheNavigation,
};
export const Example = {
parameters: {
nextjs: {
appDirectory: true,
},
},
},
If your Next.js project uses the app directory for every page (in other words, it does not have a pages directory), you can set the parameter nextjs.appDirectory to true in the preview.js file to apply it to all stories.
// .storybook/preview.js
export const parameters = {
nextjs: {
appDirectory: true,
},
};
The parameter nextjs.appDirectory defaults to false if not set.
Per-story overrides can be done by adding a nextjs.navigation property onto the story parameters. The framework will shallowly merge whatever you put here into the router.
// SomeComponentThatUsesTheNavigation.stories.js
import SomeComponentThatUsesTheNavigation from './SomeComponentThatUsesTheNavigation';
export default {
component: SomeComponentThatUsesTheNavigation,
};
// If you have the actions addon,
// you can interact with the links and see the route change events there
export const Example = {
parameters: {
nextjs: {
appDirectory: true,
navigation: {
pathname: '/profile',
query: {
user: '1',
},
},
},
},
};
Global defaults can be set in preview.js and will be shallowly merged with the default router.
// .storybook/preview.js
export const parameters = {
nextjs: {
appDirectory: true,
navigation: {
pathname: '/some-default-path',
},
},
};
useSelectedLayoutSegment and useSelectedLayoutSegments hookThe useSelectedLayoutSegment and useSelectedLayoutSegments hooks are supported in Storybook. You have to set the nextjs.navigation.segments parameter to return the segments you want to use.
// SomeComponentThatUsesTheNavigation.stories.js
import SomeComponentThatUsesTheNavigation from './SomeComponentThatUsesTheNavigation';
export default {
component: SomeComponentThatUsesTheNavigation,
parameters: {
nextjs: {
appDirectory: true,
navigation: {
segments: ['dashboard', 'analytics']
},
},
},
};
export const Example = {};
// SomeComponentThatUsesTheNavigation.js
import { useSelectedLayoutSegment, useSelectedLayoutSegments } from 'next/navigation';
export default function SomeComponentThatUsesTheNavigation() {
const segment = useSelectedLayoutSegment(); // dashboard
const segments = useSelectedLayoutSegments(); // ["dashboard", "analytics"]
...
}
The default value of nextjs.navigation.segments is [] if not set.
The default values on the stubbed navigation context are as follows:
const defaultNavigationContext = {
push(...args) {
action('nextNavigation.push')(...args);
},
replace(...args) {
action('nextNavigation.replace')(...args);
},
forward(...args) {
action('nextNavigation.forward')(...args);
},
back(...args) {
action('nextNavigation.back')(...args);
},
prefetch(...args) {
action('nextNavigation.prefetch')(...args);
},
refresh: () => {
action('nextNavigation.refresh')();
},
pathname: '/',
query: {},
};
If you override a function, you lose the automatic action tab integration and have to build it out yourself.
// .storybook/preview.js
export const parameters = {
nextjs: {
appDirectory: true,
navigation: {
push() {
// The default implementation that logs the action into the Actions panel is lost
},
},
},
};
Doing this yourself looks something like this (make sure you install the @storybook/addon-actions package):
// .storybook/preview.js
import { action } from '@storybook/addon-actions';
export const parameters = {
nextjs: {
appDirectory: true,
navigation: {
push(...args) {
// Custom logic can go here
// This logs to the Actions panel
action('nextNavigation.push')(...args);
// Return whatever you want here
return Promise.resolve(true);
},
},
},
};
next/head is supported out of the box. You can use it in your stories like you would in your Next.js application. Please keep in mind, that the Head children are placed into the head element of the iframe that Storybook uses to render your stories.
Global sass/scss stylesheets are supported without any additional configuration as well. Just import them into preview.js
import '../styles/globals.scss';
This will automatically include any of your custom sass configurations in your next.config.js file.
// next.config.js
import * as path from 'path';
export default {
// Any options here are included in Sass compilation for your stories
sassOptions: {
includePaths: [path.join(__dirname, 'styles')],
},
};
css modules work as expected.
// This import works just fine in Storybook now
import styles from './Button.module.css';
// sass/scss is also supported
// import styles from './Button.module.scss'
// import styles from './Button.module.sass'
export function Button() {
return (
<button type="button" className={styles.error}>
Destroy
</button>
);
}
The built in CSS-in-JS solution for Next.js is styled-jsx, and this framework supports that out of the box too, zero config.
// This works just fine in Storybook now
function HelloWorld() {
return (
<div>
Hello world
<p>scoped!</p>
<style jsx>{`
p {
color: blue;
}
div {
background: red;
}
@media (max-width: 600px) {
div {
background: blue;
}
}
`}</style>
<style global jsx>{`
body {
background: black;
}
`}</style>
</div>
);
}
export default HelloWorld;
You can use your own babel config too. This is an example of how you can customize styled-jsx.
// .babelrc or whatever config file you use
{
"presets": [
[
"next/babel",
{
"styled-jsx": {
"plugins": ["@styled-jsx/plugin-sass"]
}
}
]
]
}
Next.js lets you customize postcss config. Thus this framework will automatically handle your postcss config for you.
This allows for cool things like zero config tailwindcss! (See Next.js' example)
Goodbye ../! Absolute imports from the root directory work just fine.
// All good!
import Button from 'components/button';
// Also good!
import styles from 'styles/HomePage.module.css';
export default function HomePage() {
return (
<>
<h1 className={styles.title}>Hello World</h1>
<Button />
</>
);
}
Also OK for global styles in preview.js!
// .storybook/preview.js
import 'styles/globals.scss';
// ...
Next.js allows for Runtime Configuration which lets you import a handy getConfig function to get certain configuration defined in your next.config.js file at runtime.
In the context of Storybook with this framework, you can expect Next.js's Runtime Configuration feature to work just fine.
Note, because Storybook doesn't server render your components, your components will only see what they normally see on the client side (i.e. they won't see serverRuntimeConfig but will see publicRuntimeConfig).
For example, consider the following Next.js config:
// next.config.js
module.exports = {
serverRuntimeConfig: {
mySecret: 'secret',
secondSecret: process.env.SECOND_SECRET, // Pass through env variables
},
publicRuntimeConfig: {
staticFolder: '/static',
},
};
Calls to getConfig would return the following object when called within Storybook:
{
"serverRuntimeConfig": {},
"publicRuntimeConfig": {
"staticFolder": "/static"
}
}
Next.js comes with a lot of things for free out of the box like sass support, but sometimes you add custom webpack config modifications to Next.js. This framework takes care of most of the webpack modifications you would want to add. If Next.js supports a feature out of the box, then that feature will work out of the box in Storybook. If Next.js doesn't support something out of the box, but makes it easy to configure, then this framework will do the same for that thing for Storybook.
Any webpack modifications desired for Storybook should be made in .storybook/main.js.
Note: Not all webpack modifications are copy/paste-able between next.config.js and .storybook/main.js. It is recommended to do your reasearch on how to properly make your modifcation to Storybook's webpack config and on how webpack works.
Below is an example of how to add svgr support to Storybook with this framework.
// .storybook/main.js
export default {
// ...
webpackFinal: async (config) => {
// This modifies the existing image rule to exclude .svg files
// since you want to handle those files with @svgr/webpack
const imageRule = config.module.rules.find((rule) => rule.test.test('.svg'));
imageRule.exclude = /\.svg$/;
// Configure .svg files to be loaded with @svgr/webpack
config.module.rules.push({
test: /\.svg$/,
use: ['@svgr/webpack'],
});
return config;
},
};
Storybook handles most Typescript configurations, but this framework adds additional support for Next.js's support for Absolute Imports and Module path aliases. In short, it takes into account your tsconfig.json's baseUrl and paths. Thus, a tsconfig.json like the one below would work out of the box.
{
"compilerOptions": {
"baseUrl": ".",
"paths": {
"@/components/*": ["components/*"]
}
}
}
If you're using Yarn v2 or v3, you may run into issues where Storybook can't resolve style-loader or css-loader. For example, you might get errors like:
Module not found: Error: Can't resolve 'css-loader'
Module not found: Error: Can't resolve 'style-loader'
This is because those versions of Yarn have different package resolution rules than Yarn v1.x. If this is the case for you, just install the package directly.
Next.js page files can contain imports to modules meant to run in a node environment (for use in data fetching functions). If you import from a Next.js page file containing those node module imports in your stories, your Storybook's Webpack will crash because those modules will not run in a browser. To get around this, you can extract the component in your page file into a separate file and import that pure component in your stories. Or, if that's not feasible for some reason, you can polyfill those modules in your Storybook's webpackFinal configuration.
Before
// ./pages/my-page.jsx
import fs from 'fs';
// Using this component in your stories will break the Storybook build
export default function Page(props) {
return; // ...
}
export const getStaticProps = async () => {
// Logic that uses `fs`
};
After
// ./pages/my-page.jsx
import fs from 'fs';
// Use this pure component in your stories instead
import MyPage from 'components/MyPage';
export default function Page(props) {
return <MyPage {...props} />;
}
export const getStaticProps = async () => {
// Logic that uses `fs`
};
Starting with Next.js 13, you can also fetch data directly within server components in the app directory. This does not (currently) work within Storybook for similar reasons as above. It can be worked around similarly as well, by extracting a pure component to a separate file and importing that component in your stories.
Before
// ./app/my-page/index.jsx
async function getData() {
const res = await fetch(...);
// ...
}
// Using this component in your stories will break the Storybook build
export default async function Page() {
const data = await getData();
return // ...
}
After
// ./app/my-page/index.jsx
// Use this component in your stories
import MyPage from './components/MyPage';
async function getData() {
const res = await fetch(...);
// ...
}
export default async function Page() {
const data = await getData();
return <MyPage {...data} />;
}
Make sure you are treating image imports the same way you treat them when using next/image in normal development.
Before using this framework, image imports just imported the raw path to the image (e.g. 'static/media/stories/assets/logo.svg'). Now image imports work the "Next.js way", meaning that you now get an object when importing an image. For example:
{
"src": "static/media/stories/assets/logo.svg",
"height": 48,
"width": 48,
"blurDataURL": "static/media/stories/assets/logo.svg"
}
Therefore, if something in storybook isn't showing the image properly, make sure you expect the object to be returned from an import instead of just the asset path.
See local images for more detail on how Next.js treats static image imports.
You might get this if you're using Yarn v2 or v3. See Notes for Yarn v2 and v3 users for more details.
This framework borrows heavily from these Storybook addons:
