Mantine UI Library

Mantine is a fully-featured React components library with TypeScript support. It provides 100+ hooks and components with native dark mode, CSS-in-JS via CSS modules, and excellent accessibility.

When to use

• Building React applications with a comprehensive UI library
• Need TypeScript-first component library with full type safety
• Want native dark/light theme support with CSS variables
• Building forms with validation (useForm hook)
• Need utility hooks for common React patterns
• Working with Vite as build tool

Focus

This skill focuses on:

• Vite + TypeScript setup (not Next.js or CRA)
• CSS modules with PostCSS preset
• Vitest for testing
• ESLint with eslint-config-mantine

Quick Start (Vite Template)

# Use official template (recommended)
git clone https://github.com/mantinedev/vite-template my-app
cd my-app
yarn install
yarn dev

Or manual setup:

npm create vite@latest my-app -- --template react-ts
cd my-app
npm install @mantine/core @mantine/hooks
npm install -D postcss postcss-preset-mantine postcss-simple-vars

Required Packages

# Core packages
npm install @mantine/core @mantine/hooks

# Optional packages (as needed)
npm install @mantine/form          # Form management
npm install @mantine/dates dayjs   # Date components
npm install @mantine/charts recharts # Charts
npm install @mantine/notifications  # Toast notifications
npm install @mantine/modals        # Modal manager
npm install @mantine/dropzone      # File upload
npm install @mantine/spotlight     # Command palette
npm install @mantine/tiptap @tiptap/react @tiptap/pm @tiptap/starter-kit  # Rich text editor

PostCSS Configuration

Create postcss.config.cjs:

module.exports = {
  plugins: {
    'postcss-preset-mantine': {},
    'postcss-simple-vars': {
      variables: {
        'mantine-breakpoint-xs': '36em',
        'mantine-breakpoint-sm': '48em',
        'mantine-breakpoint-md': '62em',
        'mantine-breakpoint-lg': '75em',
        'mantine-breakpoint-xl': '88em',
      },
    },
  },
};

App Setup

// src/App.tsx
import '@mantine/core/styles.css';
// Other style imports as needed:
// import '@mantine/dates/styles.css';
// import '@mantine/notifications/styles.css';

import { MantineProvider, createTheme } from '@mantine/core';

const theme = createTheme({
  // Theme customization here
});

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

Critical Prohibitions

• Do NOT skip MantineProvider wrapper — all components require it
• Do NOT forget to import @mantine/core/styles.css — components won't style without it
• Do NOT mix Mantine with other UI libraries (e.g., Chakra, MUI) in same project
• Do NOT use inline styles for theme values — use CSS variables or theme object
• Do NOT skip PostCSS setup — responsive mixins won't work
• Do NOT forget key={form.key('path')} when using uncontrolled forms

Core Concepts

1. MantineProvider

Wraps your app, provides theme context and color scheme management.

2. Theme Object

Customize colors, typography, spacing, component default props.

3. Style Props

All components accept style props like mt, p, c, bg, etc.

4. CSS Variables

All theme values exposed as CSS variables (e.g., --mantine-color-blue-6).

5. Polymorphic Components

Many components support component prop to render as different elements.

Definition of Done

• MantineProvider wraps the app
• Styles imported (@mantine/core/styles.css)
• PostCSS configured with mantine-preset
• Theme customization in createTheme
• Color scheme (light/dark) handled
• TypeScript types working
• Tests pass with Vitest + custom render
