🧾 About

Tagline — One sentence describing what this library provides.

2–3 sentences: what products consume this library, what consistency problem it solves, and who maintains it.

Example:

DesignSystem Name is the shared component library and visual language for all web products at CompanyName. It replaces ad-hoc component duplication across four apps with a single, versioned source of truth — so a button change ships everywhere at once, and every product automatically passes accessibility audits.

⚙️ How It Works

Design Tokens (colors, spacing, typography)
        │
        ▼
Base Components (built on Radix UI primitives)
        │
        ▼
Composed Components (Form, DataTable, Modal...)
        │
        ▼
ThemeProvider (injects CSS custom properties at runtime)
        │
        ▼
Consumer App wraps in <ThemeProvider> → consistent UI

1. Tokens: Design decisions are encoded as CSS custom properties, not hardcoded values in components.
2. Primitives: Low-level components handle accessibility (ARIA, keyboard nav) via Radix UI.
3. Composed Components: Higher-level components combine primitives for common patterns (forms, tables, modals).
4. Theming:

   ThemeProvider

   swaps the token values at runtime — dark mode, custom brand colors, and whitelabeling all work the same way.

💼 Real-World Use Cases

• Multi-product Companies: A shared library means the same Button renders identically across the marketing site, the app, and the admin dashboard — with no copy-paste.
• Design-Dev Handoff: Designers define tokens in Figma; developers consume the same values via CSS custom properties. No more "that's not quite the right shade of blue."
• Whitelabeling / SaaS: Customers get a branded experience by passing a custom theme object to

  ThemeProvider

  — no forking required.
• Accessibility Compliance: Build WCAG 2.1 AA compliance into the library once, and every product inherits it automatically.

📦 Installation

npm install @yourorg/design-system

# Peer dependencies
npm install react react-dom

---

🚀 Quick Start

import { ThemeProvider, Button, Card } from "@yourorg/design-system";
import "@yourorg/design-system/styles.css";

function App() {
  return (
    <ThemeProvider theme="light">
      <Card>
        <Button variant="primary" size="md">
          Get Started
        </Button>
      </Card>
    </ThemeProvider>
  );
}

💡 Usage

Importing components

import { Button, Input, Modal, Toast } from "@yourorg/design-system";

Button variants

<Button variant="primary">Primary</Button>
<Button variant="secondary">Secondary</Button>
<Button variant="ghost">Ghost</Button>
<Button variant="destructive" size="sm">Delete</Button>

Form example

import { Input, Label, Button } from "@yourorg/design-system";

function LoginForm() {
  return (
    <form>
      <Label htmlFor="email">Email</Label>
      <Input id="email" type="email" placeholder="you@example.com" />
      <Button type="submit" variant="primary">Sign In</Button>
    </form>
  );
}

Opening a Modal

import { Modal, Button } from "@yourorg/design-system";

function Example() {
  const [open, setOpen] = useState(false);
  return (
    <>
      <Button onClick={() => setOpen(true)}>Open Modal</Button>
      <Modal open={open} onClose={() => setOpen(false)} title="Confirm Action">
        Are you sure you want to continue?
      </Modal>
    </>
  );
}
