Setup Mantine in Storybook

Note that this guide covers only Storybook 7.0+ integration. If you are using older version of Storybook, it will not work for you.

Add Storybook to your application

If you already have Storybook in your application, you can skip this step.

Follow Storybook getting started guide to add Storybook to your application:

npx storybook@latest init

Configure addons

Note that @storybook/addon-styling-webpack is required only if you are not using Vite. If you are using Vite, do not install @storybook/addon-styling-webpack and do not add it to the addons section in main.ts file.

Install Storybook addons:

yarn add --dev storybook-dark-mode @storybook/addon-styling-webpack

Add addons to .storybook/main.ts:

import type { StorybookConfig } from '@storybook/react-vite';

const config: StorybookConfig = {
  // ... other config properties
  addons: [
    // ... other addons
    '@storybook/addon-styling-webpack', // Add this line only if you are not using Vite

export default config;

Theme object

To shared theme object between your application and Storybook, create src/theme.ts (or any other path in your application) file with your theme override:

// src/theme.ts
import { createTheme } from '@mantine/core';

export const theme = createTheme({
  fontFamily: 'serif',
  // ... other theme override properties

Then you will be able to use the same theme both in your application and Storybook:

// In your application

import { MantineProvider } from '@mantine/core';
import { theme } from './theme';

function App() {
  return <MantineProvider theme={theme}>{/* ... */}</MantineProvider>;

Storybook preview

If .storybook/preview.tsx file does not exist, create it and add the following content:

// Import styles of packages that you've installed.
// All packages except `@mantine/hooks` require styles imports
import '@mantine/core/styles.css';

import React, { useEffect } from 'react';
import { addons } from '@storybook/preview-api';
import { DARK_MODE_EVENT_NAME } from 'storybook-dark-mode';
import {
} from '@mantine/core';
// theme.ts file from previous step
import { theme } from '../src/theme';

const channel = addons.getChannel();

function ColorSchemeWrapper({
}: {
  children: React.ReactNode;
}) {
  const { setColorScheme } = useMantineColorScheme();
  const handleColorScheme = (value: boolean) =>
    setColorScheme(value ? 'dark' : 'light');

  useEffect(() => {
    channel.on(DARK_MODE_EVENT_NAME, handleColorScheme);
    return () =>, handleColorScheme);
  }, [channel]);

  return <>{children}</>;

export const decorators = [
  (renderStory: any) => (
  (renderStory: any) => (
    <MantineProvider theme={theme}>{renderStory()}</MantineProvider>

All set! Start Storybook:

npm run storybook
