How to Use React Aria Components For Web Accessibility

In today’s web development, it’s more important than ever to build applications that are accessible and visually appealing. React Aria Components gives developers a flexible, scalable API to build accessible UI components with ease. With over 50+ components that include built-in behavior and top-notch accessibility, React Aria makes it easy to integrate accessibility best practices into your project.

Whether you’re starting a new project or enhancing an existing one, their hook-based API gives developers the flexibility to adapt simple interactions and complex interfaces to exact requirements.

This blog will help you get started with React Aria, implement common UI interactions, and extend components to fit your custom design system—so your applications can reach a global audience.

Understanding React Aria Components

Overview and Key Benefits

React Aria Components are designed to deliver unstyled, behavior-rich components that form the building blocks of accessible user interfaces. They are ideal for:

• Flexibility: Developers can style components from scratch while retaining accessible behaviors.
• Scalability: A component library capable of handling everything from small interactions to complex UI patterns.
• Built-in DOM Structure: Ensures semantic HTML and ARIA roles are applied correctly.
• Global Compatibility: Out-of-the-box internationalization supports developers in making applications for a global audience.

React Aria ensures that every component adheres to strict accessibility standards without compromising on performance.

Feature	Benefit
Over 50 built-in components	Wide coverage for common UI interactions
Flexible API and hook-based design	Allows custom styling and interaction designs
Accessible by design	Adheres to accessibility standards with minimal effort
Internationalization support	Makes adapting components easy for multiple locales

Building Accessible UI Components with React Aria

React Aria Components excel in handling various user interactions while preserving accessibility. Two common examples include drag and drop interactions and date/time pickers.

Drag and Drop Interactions

Implementing drag and drop with React Aria is streamlined through its hook-based API. Hooks allow you to manage states and interactions without compromising accessibility, and they support even complex patterns like time-based drag.

Best Practices for Drag and Drop

• Use Semantic Markup: Use elements like <ul> for lists.
• Manage Focus: Ensure focus is correctly maintained through all events.
• Provide Visual Feedback: Use styles and animations to reinforce interactions.

Example: Basic Drag and Drop

1import React, { useState } from 'react';
2import { useDraggable, useDroppable } from 'react-aria';
3
4function DraggableItem({ id, onDragEnd }) {
5  const { dragProps, isDragging } = useDraggable({
6    onDragEnd: (event) => onDragEnd(id, event)
7  });
8
9  return (
10    <div
11      {...dragProps}
12      style={{
13        opacity: isDragging ? 0.5 : 1,
14        padding: '8px',
15        margin: '4px',
16        backgroundColor: '#efefef',
17        border: '1px solid #ddd',
18        cursor: 'grab'
19      }}
20    >
21      Draggable Item {id}
22    </div>
23  );
24}
25
26function DroppableArea({ onDrop, children }) {
27  const { dropProps, isOver } = useDroppable({
28    onDrop: onDrop
29  });
30
31  return (
32    <div
33      {...dropProps}
34      style={{
35        padding: '16px',
36        margin: '8px',
37        border: '2px dashed #aaa',
38        backgroundColor: isOver ? '#d0f0c0' : '#fff'
39      }}
40    >
41      {children}
42    </div>
43  );
44}
45
46export default function DragAndDropExample() {
47  const [items, setItems] = useState([1, 2, 3]);
48
49  const handleDrop = (id, event) => {
50    console.log(`Item ${id} dropped!`);
51  };
52
53  return (
54    <div style={{ display: 'flex', flexDirection: 'column', alignItems: 'center' }}>
55      <DroppableArea onDrop={(event) => console.log('Dropped!', event)}>
56        {items.map((id) => (
57          <DraggableItem key={id} id={id} onDragEnd={handleDrop} />
58        ))}
59      </DroppableArea>
60    </div>
61  );
62}

This approach maintains accessibility while allowing control over styles and behavior.

Date and Time Pickers

Date and time pickers are essential in many apps. React Aria provides robust mechanisms for building accessible, keyboard-navigable, and custom-styled pickers.

Best Practices

• Custom Render Props: Tailor interaction and styling.
• Keyboard Navigation: Ensure full keyboard support.
• Smooth Animations: Improve usability with CSS transitions.
• Screen Reader Support: Provide ARIA labels and announcements.

Example: Basic Date Picker

1import React, { useState } from 'react';
2import { useDatePicker } from 'react-aria';
3
4function DatePicker({ onDateChange }) {
5  const [selectedDate, setSelectedDate] = useState(new Date());
6
7  const { inputProps, calendarProps } = useDatePicker({
8    value: selectedDate,
9    onChange: (newDate) => {
10      setSelectedDate(newDate);
11      onDateChange(newDate);
12    }
13  });
14
15  return (
16    <div>
17      <input {...inputProps} style={{ padding: '8px', border: '1px solid #ccc' }} />
18      <div {...calendarProps} style={{ marginTop: '8px' }}>
19        <p>Selected Date: {selectedDate.toLocaleDateString()}</p>
20      </div>
21    </div>
22  );
23}
24
25export default DatePicker;

Advanced React Aria Components

React Aria Components also support more sophisticated UI features like overlays, navigation panels, and custom integrations.

Navigation Overlays and Pickers

Navigation overlays improve UX by offering contextual content. React Aria simplifies this with pre-built hooks.

Key Considerations

• Accessibility: Trap focus and provide labels.
• Custom Animation: Use smooth transitions.
• Design System Integration: Maintain consistent theming.

Example: Navigation Overlay

1import React from 'react';
2import { useOverlay, usePreventScroll } from 'react-aria';
3
4function NavigationOverlay({ isOpen, onClose, children }) {
5  usePreventScroll();
6  let { overlayProps } = useOverlay({ isOpen, onClose });
7
8  if (!isOpen) return null;
9
10  return (
11    <div
12      {...overlayProps}
13      style={{
14        position: 'fixed',
15        top: 0, left: 0, right: 0, bottom: 0,
16        backgroundColor: 'rgba(0, 0, 0, 0.5)',
17        display: 'flex', alignItems: 'center', justifyContent: 'center'
18      }}
19    >
20      <div style={{ background: '#fff', padding: '24px', borderRadius: '4px' }}>
21        <button onClick={onClose} style={{ float: 'right' }}>Close</button>
22        {children}
23      </div>
24    </div>
25  );
26}
27
28export default NavigationOverlay;

Custom Patterns and Integration Strategies

Customizing React Aria to fit your design system is where it shines.

Effective Strategies

• Use hook-based APIs to extend behaviors
• Support dark mode through context and dynamic styling
• Improve screen reader experience via ARIA messages
• Implement locale-aware formatting
• Build a unified design system on top of React Aria

Example: Dark Mode Button with Context

1import React, { createContext, useContext } from 'react';
2import { useButton } from 'react-aria';
3
4const ThemeContext = createContext('light');
5
6function ThemedButton(props) {
7  const theme = useContext(ThemeContext);
8  const { buttonProps } = useButton(props);
9
10  return (
11    <button
12      {...buttonProps}
13      style={{
14        padding: '10px 20px',
15        border: 'none',
16        borderRadius: '4px',
17        backgroundColor: theme === 'dark' ? '#333' : '#007acc',
18        color: '#fff'
19      }}
20    >
21      {props.children}
22    </button>
23  );
24}
25
26function App() {
27  return (
28    <ThemeContext.Provider value="dark">
29      <ThemedButton onPress={() => alert('Button pressed!')}>
30        Click Me
31      </ThemedButton>
32    </ThemeContext.Provider>
33  );
34}
35
36export default App;
