This guide will help you create your first components with Zayne Labs UI. We’ll walk through basic usage patterns and show you how to compose components together.

​
Setup

1

Install the package

First, install Zayne Labs UI and its peer dependencies:
npm install @zayne-labs/ui-react react@19 react-dom@19
2

Import components

Import the components you need. Each component is available as a separate module:
import { Switch } from "@zayne-labs/ui-react/common/switch";
import { Card } from "@zayne-labs/ui-react/ui/card";
3

Start building

Use the components in your app. All components are headless - bring your own styles!

​
Basic examples

​
Conditional rendering with Switch

The Switch component provides pattern matching for conditional rendering, similar to a switch statement: 
import { Switch } from "@zayne-labs/ui-react/common/switch";

export default function App() {
  const status = "loading";

  return (
    <Switch.Root value={status}>
      <Switch.Match when="loading">
        <div>Loading...</div>
      </Switch.Match>

      <Switch.Match when="error">
        <div>Something went wrong</div>
      </Switch.Match>

      <Switch.Default>
        <div>Content loaded!</div>
      </Switch.Default>
    </Switch.Root>
  );
}

​
List rendering with For

The For component makes list rendering declarative and handles empty states: 
import { For } from "@zayne-labs/ui-react/common/for";

interface User {
  id: string;
  name: string;
}

export function UserList({ users }: { users: User[] }) {
  return (
    <For each={users} fallback={<p>No users found</p>}>
      {(user) => <div key={user.id}>{user.name}</div>}
    </For>
  );
}

​
Building a card layout

The Card component provides a composable structure for card-based layouts: 
import { Card } from "@zayne-labs/ui-react/ui/card";

export function ProductCard() {
  return (
    <Card.Root className="border rounded-lg p-4">
      <Card.Header>
        <Card.Title>Premium Headphones</Card.Title>
        <Card.Description>High-quality audio experience</Card.Description>
      </Card.Header>
      
      <Card.Content className="mt-4">
        <p>Immerse yourself in crystal-clear sound with our latest headphones.</p>
      </Card.Content>
      
      <Card.Footer className="mt-4">
        <Card.Action className="bg-blue-500 text-white px-4 py-2 rounded">
          Add to Cart
        </Card.Action>
      </Card.Footer>
    </Card.Root>
  );
}

​
File upload with DropZone

The DropZone component provides a complete file upload solution with drag-and-drop support: 
import { DropZone } from "@zayne-labs/ui-react/ui/drop-zone";

export function FileUploader() {
  return (
    <DropZone.Root
      accept={{ "image/*": [] }}
      maxFiles={5}
      maxFileSize={5 * 1024 * 1024} // 5MB
    >
      <DropZone.Area className="border-2 border-dashed rounded-lg p-8">
        {({ isDraggingOver }) => (
          <div>
            <p>{isDraggingOver ? "Drop files here" : "Drag files here or click to browse"}</p>
            <DropZone.Trigger className="mt-4 px-4 py-2 bg-blue-500 text-white rounded">
              Select Files
            </DropZone.Trigger>
          </div>
        )}
      </DropZone.Area>

      <DropZone.FileList className="mt-4 space-y-2" renderMode="per-item">
        {({ fileState }) => (
          <DropZone.FileItem fileState={fileState} className="flex items-center gap-4 p-4 border rounded">
            <DropZone.FileItemPreview className="size-12" />
            <DropZone.FileItemMetadata />
            <DropZone.FileItemDelete className="ml-auto text-red-500">
              Remove
            </DropZone.FileItemDelete>
          </DropZone.FileItem>
        )}
      </DropZone.FileList>
    </DropZone.Root>
  );
}

​
Composing components

Zayne Labs UI components work great together. Here’s an example combining Show, For, and Card: 
import { Show } from "@zayne-labs/ui-react/common/show";
import { For } from "@zayne-labs/ui-react/common/for";
import { Card } from "@zayne-labs/ui-react/ui/card";

interface Product {
  id: string;
  name: string;
  price: number;
}

export function ProductGrid({ products, loading }: { products: Product[]; loading: boolean }) {
  return (
    <Show.Root when={!loading} fallback={<div>Loading products...</div>}>
      <div className="grid grid-cols-3 gap-4">
        <For each={products} fallback={<p>No products available</p>}>
          {(product) => (
            <Card.Root key={product.id} className="border rounded-lg p-4">
              <Card.Header>
                <Card.Title>{product.name}</Card.Title>
              </Card.Header>
              <Card.Content>
                <p className="text-lg font-bold">${product.price}</p>
              </Card.Content>
            </Card.Root>
          )}
        </For>
      </div>
    </Show.Root>
  );
}
