Installation

Conty Design System is distributed as an npm package. This guide will walk you through installing and configuring Conty in your React project.

Prerequisites

Before installing Conty, ensure your project meets these requirements:

Node.js >= 20

Conty requires Node.js version 20 or higher.

node --version
# Should output v20.x.x or higher

React 19

Conty is built for React 19. Make sure your project uses compatible versions:

package.json

{
  "dependencies": {
    "react": "^19.0.0",
    "react-dom": "^19.0.0"
  }
}

TypeScript (Recommended)

While not required, TypeScript is highly recommended for the best developer experience.

npm install -D typescript

Install the Package

Install the main design system package using your preferred package manager:

npm install @conty/design-system

The @conty/design-system package automatically includes @conty/tokens and @conty/ui as dependencies.

Peer Dependencies

Conty has the following peer dependencies that should already be in your project:

package.json

{
  "peerDependencies": {
    "react": "^19.0.0",
    "react-dom": "^19.0.0"
  }
}

If you don’t have these installed, add them:

npm install react react-dom

Import Styles

Conty requires you to import its CSS file in your application entry point.

Next.js
Vite
Create React App

Import the styles in your root layout or _app.tsx:

app/layout.tsx

import '@conty/design-system/styles.css'

export default function RootLayout({
  children,
}: {
  children: React.ReactNode
}) {
  return (
    <html lang="en">
      <body>{children}</body>
    </html>
  )
}

Import the styles in your main.tsx or App.tsx:

src/main.tsx

import React from 'react'
import ReactDOM from 'react-dom/client'
import '@conty/design-system/styles.css'
import App from './App'

ReactDOM.createRoot(document.getElementById('root')!).render(
  <React.StrictMode>
    <App />
  </React.StrictMode>
)

Import the styles in your index.tsx:

src/index.tsx

import React from 'react'
import ReactDOM from 'react-dom/client'
import '@conty/design-system/styles.css'
import App from './App'

const root = ReactDOM.createRoot(
  document.getElementById('root') as HTMLElement
)
root.render(
  <React.StrictMode>
    <App />
  </React.StrictMode>
)

The styles.css file includes both the design tokens (@conty/tokens/theme.css) and component styles (@conty/ui/styles.css).

TypeScript Configuration

For optimal TypeScript support, configure your tsconfig.json:

tsconfig.json

{
  "compilerOptions": {
    "target": "ES2020",
    "lib": ["ES2020", "DOM", "DOM.Iterable"],
    "module": "ESNext",
    "moduleResolution": "bundler",
    "jsx": "react-jsx",
    "strict": true,
    "esModuleInterop": true,
    "skipLibCheck": true,
    "resolveJsonModule": true,
    "isolatedModules": true,
    "noEmit": true
  }
}

Conty is built as ESM modules. Make sure your bundler (Vite, Next.js, etc.) supports ESM.

Tailwind CSS Configuration (Optional)

If you’re using Tailwind CSS in your project, you may want to extend your configuration to use Conty’s design tokens:

tailwind.config.js

/** @type {import('tailwindcss').Config} */
export default {
  content: [
    './src/**/*.{js,jsx,ts,tsx}',
    './node_modules/@conty/ui/dist/**/*.js',
  ],
  theme: {
    extend: {
      colors: {
        background: 'var(--background)',
        foreground: 'var(--foreground)',
        primary: 'var(--primary)',
        'primary-foreground': 'var(--primary-foreground)',
        secondary: 'var(--secondary)',
        'secondary-foreground': 'var(--secondary-foreground)',
        muted: 'var(--muted)',
        'muted-foreground': 'var(--muted-foreground)',
        border: 'var(--border)',
        destructive: 'var(--destructive)',
      },
      borderRadius: {
        sm: 'var(--radius-sm)',
        md: 'var(--radius-md)',
        lg: 'var(--radius-lg)',
      },
    },
  },
}

Conty components already include all necessary Tailwind classes. You only need to configure Tailwind if you want to use the design tokens in your own custom components.

Dark Mode Setup

Conty’s dark mode works by toggling a .dark class on a parent element (usually <html> or <body>).

Next.js (next-themes)
Manual Toggle

Install and configure next-themes:

npm install next-themes

app/providers.tsx

'use client'

import { ThemeProvider } from 'next-themes'

export function Providers({ children }: { children: React.ReactNode }) {
  return (
    <ThemeProvider attribute="class" defaultTheme="system" enableSystem>
      {children}
    </ThemeProvider>
  )
}

app/layout.tsx

import { Providers } from './providers'
import '@conty/design-system/styles.css'

export default function RootLayout({ children }) {
  return (
    <html lang="en" suppressHydrationWarning>
      <body>
        <Providers>{children}</Providers>
      </body>
    </html>
  )
}

Implement a simple dark mode toggle:

import { useState, useEffect } from 'react'

export function useDarkMode() {
  const [isDark, setIsDark] = useState(false)

  useEffect(() => {
    const root = window.document.documentElement
    if (isDark) {
      root.classList.add('dark')
    } else {
      root.classList.remove('dark')
    }
  }, [isDark])

  return [isDark, setIsDark] as const
}

Use in your component:

import { Button } from '@conty/design-system'
import { useDarkMode } from './useDarkMode'

export function App() {
  const [isDark, setIsDark] = useDarkMode()
  
  return (
    <Button onClick={() => setIsDark(!isDark)}>
      Toggle {isDark ? 'Light' : 'Dark'} Mode
    </Button>
  )
}

Verify Installation

Create a simple test component to verify everything is working:

src/App.tsx

import { Button, Card, CardHeader, CardTitle, CardContent } from '@conty/design-system'

export default function App() {
  return (
    <div className="p-8">
      <Card>
        <CardHeader>
          <CardTitle>Installation Successful!</CardTitle>
        </CardHeader>
        <CardContent>
          <Button>Click me</Button>
        </CardContent>
      </Card>
    </div>
  )
}

If you see a styled card with a button, you’re all set!

Troubleshooting

Styles not loading

Make sure you’ve imported @conty/design-system/styles.css in your application entry point. Check your bundler’s configuration to ensure it can handle CSS imports.

TypeScript errors

Ensure you’re using TypeScript 5.0+ and that your tsconfig.json has moduleResolution: "bundler" or "node16".

Peer dependency warnings

Make sure you have React 19 installed. Conty requires react@^19.0.0 and react-dom@^19.0.0.

Dark mode not working

Verify that the .dark class is being applied to your <html> or root element. Check browser DevTools to inspect the class.
