🏛️ Architectural Excellence

DS3 UI is built on six powerful architectural patterns that work together to deliver exceptional developer and user experiences:

1. 🌐 Platform Adaptation

Components intelligently adapt to their environment while maintaining consistent APIs:

// Same import, same API, platform-perfect behavior
import { Input } from '@consensys/ds3';

// Works perfectly on web and native
<Input 
  placeholder="Enter your name"
  color="primary"
/>

DS3 UI components follow a consistent organization pattern that enables cross-platform functionality:

Component Architecture

File	Purpose
Component.tsx	React Native implementation
Component.web.tsx	Web implementation
Component.shared.tsx	Shared compound elements (Icon, Text, etc.)
context.ts	State sharing for compound components
styles.ts	Shared CVA styling definitions
utils.ts	Dual-API handling
types.ts	TypeScript type definitions
index.ts	Named exports

Implementation Strategies

DS3 UI uses two main approaches to implement cross-platform components:

1. Custom Implementation

Most components like <Button />, <Input />, and <Icon /> use platform-specific implementations:

// Input.tsx (React Native specific)
export const Input = (props) => <TextInput {...props} />;

// Input.web.tsx (Web specific)
export const Input = (props) => <input {...props} />;

2. Primitives-Based Implementation

Some components build on existing accessibility primitives:

// Checkbox.tsx uses RN Primitives
import * as CheckboxPrimitive from '@rn-primitives/checkbox';

// Checkbox.web.tsx uses Radix UI
import * as CheckboxPrimitive from '@radix-ui/react-checkbox';

These leverage Radix UI (web) and RN Primitives (React Native) for consistent behavior and accessibility.

2. 🧩 Compound Components

Simple by default, infinitely customizable when needed:

// Simple usage - clean and concise
<Button color="primary">
  Sign Up
</Button>

// Advanced usage - full control over structure and styling
<Button variant="outline" color="primary" className="px-8 rounded-full">
  <Icon icon={Mail} className="mr-2" />
  <Text className="font-bold tracking-wide">Contact Us</Text>
  <Spinner spinner={RefreshCw} className="ml-3 animate-spin" />
</Button>

Power features:

• ⚡ Context sharing - Child components automatically inherit parent state
• 🎛️ Precise control - Position and style each element exactly how you want
• 🎭 Dynamic rendering - Show/hide elements based on component state

For a deeper dive into the pattern, see the Patterns.dev guide.

3. 🔌 Framework Integration

Consistent experience across multiple React frameworks:

// Works in React DOM (Vite)
// Works in React Native (Expo)
// Works in Next.js (coming soon)
import { Button, Input } from '@consensys/ds3';

Integration features:

• 🏗️ Framework plugins - Easy setup with @consensys/ds3-config framework-specific plugins
• 🧰 Configuration presets - Optimized defaults for each framework
• 🔄 Shared APIs - Consistent component behavior regardless of framework

Framework-specific optimizations are handled by @consensys/ds3-config plugins, allowing your components to work seamlessly in any React environment.

4. ♿ Accessibility By Default

Ship accessible experiences without extra effort:

• 🔤 ARIA mapping - Web attributes automatically map to native equivalents
• ⌨️ Keyboard navigation - Full keyboard support on every platform
• 🗣️ Screen reader optimization - Proper roles and states for assistive technology
• 🌈 Focus management - Visual indicators and proper focus trapping

🔄 Accessibility Prop Mapping

The library automatically maps accessibility props between platforms. Here are a few common examples:

Web Props	Native Props	Component
aria-disabled	accessibilityState.disabled	Button, Input
aria-busy	accessibilityState.busy	Button, Input
role="button"	accessibilityRole="button"	Button

// Web accessibility
<Button 
  aria-disabled={isLoading}
  aria-busy={isLoading}
  role="button"
>
  Submit
</Button>

// Native accessibility
<Button 
  accessibilityState={{
    disabled: isLoading,
    busy: isLoading
  }}
  accessibilityRole="button"
>
  <Text>Submit</Text>
</Button>

5. 🎨 Unified Styling

One styling system, perfect everywhere:

// Consistent styling API across platforms
<Text 
  size="lg" 
  weight="bold" 
  color="primary"
  className="underline opacity-90" // Works on web and native!
/>

Style features:

• 🌊 Tailwind + NativeWind - Use familiar Tailwind CSS classes everywhere through NativeWind
• 🎭 Variants - Consistent styling API with class-variance-authority (CVA)
• 🎛️ Theme tokens - Shared design tokens for colors, spacing, and typography

6. 🔄 Dual API

While Platform Adaptation handles the underlying implementation differences, Dual API gives you the freedom to write code in your preferred style. Whether you're a web developer or React Native developer, you can use the APIs you're most comfortable with.

Dual API features:

• 🌐 Web-first development - Use familiar DOM APIs (onClick, onChange, type)
• 📱 Native-first development - Use React Native APIs (onPress, onChangeText)
• 🛡️ Type safety - Full TypeScript support for both platforms
• 🔄 Automatic conversion - Props map correctly between platforms
• 🧠 Smart detection - Components adapt to how you use them

📋 The Rules

• 🌐 Web-only Development

  • Use ONLY web props (onClick, onChange, type)
  • Get full DOM access and browser features
  • Perfect for web-only applications

• 📱 Native/Hybrid Development

  • Use ONLY native props (onPress, onChangeText)
  • Consistent with React Native patterns
  • Works across all platforms

• ⚠️ Never Mix APIs

  // ❌ INCORRECT: Using web props in native/hybrid code
  <Button 
    onClick={() => {}} // Will be ignored on native!
    onPress={handlePress}
  >
    <Text>Mixed Props Button</Text>
  </Button>
  
  // ✅ CORRECT: 🌐 Web-only code can use web props
  <Button 
    onClick={handleClick} // Perfectly fine in web-only code!
  >
    <Text>Web Button</Text>
  </Button>
  
  // ✅ CORRECT: 📱🌐  Native/hybrid code must use native props
  <Button 
    onPress={handlePress}
  >
    <Text>Native Button</Text>
  </Button>
  

🔄 Prop Mapping

For hybrid applications, the library automatically maps native props to web props. This one-way mapping ensures React Native code works seamlessly on web. Here are a few common examples:

Native Props	Web Props	Component
onPress	onClick	Button
onChangeText	onChange	Input
secureTextEntry	type="password"	Input

⚠️ Important Rules:

• Never use web props in native code - they will be silently ignored
• Never mix web and native props - choose one style and stick with it

📘 Type-Safe Events

The library provides platform-specific event types for type safety:

import type { WebClickEvent, NativePressEvent } from '@consensys/ds3';

// 🌐 Web events
<Button onClick={(e: WebClickEvent) => console.log(e.currentTarget)}>
  Click Me
</Button>

// 📱 Native events
<Button onPress={(e: NativePressEvent) => console.log(e.nativeEvent)}>
  <Text>Press Me</Text>
</Button>

Web Types	Native Types	Description
WebClickEvent	NativePressEvent	Button click/press events
WebFocusEvent	NativeFocusEvent	Focus/blur events
WebChangeEvent	NativeChangeEvent	Input change events

🎯 Platform Adaptation vs Dual API

• Platform Adaptation: Handles the underlying implementation differences (DOM vs Native)
• Dual API: Gives you the freedom to write code in your preferred style

7. 🔌 Slot Pattern

Replace any component part with your own elements:

// Button as a link using asChild
<Button variant="solid" color="primary" asChild>
  <a href="https://example.com">Visit Website</a>
</Button>

// Button as a router link
<Button variant="outline" color="secondary" asChild>
  <Link to="/dashboard">Go to Dashboard</Link>
</Button>

The Slot pattern allows you to replace a component's default root element with your own custom element, while preserving all styling, behavior, and accessibility features.

When you pass asChild={true} to a component:

• The component renders a Slot component instead of its default element
• The Slot captures all props from the parent component
• It applies those props to the first child element you provide
• The child element becomes the new root, inheriting all behavior

The rendered DOM with asChild would be essentially:

<a 
  href="https://example.com" 
  class="bg-neutral-a11"
  role="button"
>
  Visit Website
</a>

Our components use different Slot implementations based on platform:

• Web: Uses @radix-ui/react-slot for DOM elements
• Native: Uses @rn-primitives/slot for React Native components

This allows the same API to work seamlessly across platforms while respecting platform-specific behavior.

Slot power:

• 🎭 Style inheritance - Your elements inherit DS3 styling
• 🔌 Behavior injection - DS3 behaviors transfer to your elements
• ♿ Accessibility transfer - Accessibility attributes preserved
