React Aria Patterns

Build accessible UI components using Adobe's React Aria hooks library with React 19 patterns.

Overview

  • Building accessible buttons, links, and toggles with keyboard/screen reader support

  • Implementing modal dialogs with proper focus management and trapping

  • Creating autocomplete/combobox components with filtering and selection

  • Building menu systems with roving tabindex and proper ARIA roles

  • Implementing accessible tables, listboxes, and selection patterns

Quick Reference

useButton - Accessible Button Component

import { useRef } from 'react'; import { useButton, useFocusRing, mergeProps } from 'react-aria'; import type { AriaButtonProps } from 'react-aria';

function Button(props: AriaButtonProps & { className?: string }) { const ref = useRef<HTMLButtonElement>(null); const { focusProps, isFocusVisible } = useFocusRing(); const { buttonProps } = useButton(props, ref);

return ( <button {...mergeProps(buttonProps, focusProps)} ref={ref} className={${props.className ?? ''} ${isFocusVisible ? 'ring-2 ring-blue-500' : ''}} > {props.children} </button> ); }

useDialog - Modal Dialog with Focus Management

import { useRef } from 'react'; import { useDialog, useModalOverlay, FocusScope, mergeProps } from 'react-aria'; import { useOverlayTriggerState } from 'react-stately';

function Modal({ state, title, children }) { const ref = useRef<HTMLDivElement>(null); const { modalProps, underlayProps } = useModalOverlay({}, state, ref); const { dialogProps, titleProps } = useDialog({ 'aria-label': title }, ref);

return ( <div {...underlayProps} className="fixed inset-0 z-50 bg-black/50 flex items-center justify-center"> <FocusScope contain restoreFocus autoFocus> <div {...mergeProps(modalProps, dialogProps)} ref={ref} className="bg-white rounded-lg p-6"> <h2 {...titleProps} className="text-xl font-semibold mb-4">{title}</h2> {children} </div> </FocusScope> </div> ); }

useComboBox - Accessible Autocomplete

import { useRef } from 'react'; import { useComboBox, useFilter } from 'react-aria'; import { useComboBoxState } from 'react-stately';

function ComboBox(props) { const { contains } = useFilter({ sensitivity: 'base' }); const state = useComboBoxState({ ...props, defaultFilter: contains }); const inputRef = useRef(null), buttonRef = useRef(null), listBoxRef = useRef(null);

const { buttonProps, inputProps, listBoxProps, labelProps } = useComboBox( { ...props, inputRef, buttonRef, listBoxRef }, state );

return ( <div className="relative inline-flex flex-col"> <label {...labelProps}>{props.label}</label> <div className="flex"> <input {...inputProps} ref={inputRef} className="border rounded-l px-3 py-2" /> <button {...buttonProps} ref={buttonRef} className="border rounded-r px-2">&#9660;</button> </div> {state.isOpen && ( <ul {...listBoxProps} ref={listBoxRef} className="absolute top-full w-full border bg-white"> {[...state.collection].map((item) => ( <li key={item.key} className="px-3 py-2 hover:bg-gray-100">{item.rendered}</li> ))} </ul> )} </div> ); }

Key Decisions

Decision Option A Option B Recommendation

Hook vs Component useButton hooks Button from react-aria-components Hooks for control, Components for speed

Focus Management Manual tabIndex

FocusScope component FocusScope - trapping, restore, auto-focus

Virtual Lists Native scroll useVirtualizer

  • useListBox

Virtualizer for lists > 100 items

State Management Local useState react-stately hooks react-stately - designed for a11y

Anti-Patterns (FORBIDDEN)

// NEVER use div with onClick for interactive elements <div onClick={handleClick}>Click me</div> // Missing keyboard support!

// ALWAYS use useButton or native button const { buttonProps } = useButton({ onPress: handleClick }, ref); <div {...buttonProps} ref={ref}>Click me</div>

// NEVER handle focus manually for modals useEffect(() => { modalRef.current?.focus(); }, []); // Incomplete!

// ALWAYS use FocusScope for modals/overlays <FocusScope contain restoreFocus autoFocus> <div role="dialog">...</div> </FocusScope>

// NEVER forget aria-live for dynamic announcements <div>{errorMessage}</div> // Screen readers won't announce!

// ALWAYS use aria-live for status updates <div aria-live="polite" className="sr-only">{errorMessage}</div>

// NEVER omit label associations <input type="text" placeholder="Email" /> // No accessible name!

// ALWAYS associate labels properly <label {...labelProps}>Email</label> <input {...inputProps} />
