React Aria无障碍库 - 完整可访问组件库指南 ​

1. React Aria简介 ​

1.1 什么是React Aria ​

React Aria是Adobe开发的一套React Hooks库,提供了完整的可访问性解决方案,实现了ARIA规范和最佳实践。

typescript
const reactAriaFeatures = {
  accessibility: [
    '完整的ARIA支持',
    '键盘导航',
    '焦点管理',
    '屏幕阅读器优化'
  ],
  
  internationalization: [
    '国际化日期时间',
    '数字格式化',
    'RTL布局支持',
    '多语言支持'
  ],
  
  interaction: [
    '触摸手势',
    '鼠标交互',
    '键盘交互',
    '跨平台支持'
  ],
  
  components: [
    '按钮',
    '表单',
    '对话框',
    '菜单',
    '列表',
    '日期选择器',
    '等等...'
  ]
};

1.2 安装和设置 ​

bash
# 核心库
npm install react-aria

# 或分别安装需要的包
npm install @react-aria/button
npm install @react-aria/dialog
npm install @react-aria/menu
npm install @react-aria/focus

# 状态管理(可选)
npm install @react-stately/button
npm install @react-stately/menu

# 类型定义
npm install @react-types/button @react-types/shared

1.3 基础使用 ​

tsx
import { useButton } from '@react-aria/button';
import { useRef } from 'react';

function Button(props) {
  const ref = useRef<HTMLButtonElement>(null);
  const { buttonProps } = useButton(props, ref);
  
  return (
    <button {...buttonProps} ref={ref}>
      {props.children}
    </button>

11.2 可访问的数据表格 ​

tsx
// DataTable.tsx
import { useTable } from '@react-aria/table';
import { useTableState } from '@react-stately/table';

export function DataTable({ columns, rows }) {
  const state = useTableState({
    children: rows.map(row => (
      <Row key={row.id}>
        {columns.map(col => (
          <Cell key={col.key}>{row[col.key]}</Cell>
        ))}
      </Row>
    ))
  });
  
  const ref = useRef<HTMLTableElement>(null);
  const { gridProps } = useTable({ 'aria-label': '数据表格' }, state, ref);
  
  return (
    <table {...gridProps} ref={ref}>
      <thead>
        <tr>
          {columns.map(col => (
            <th key={col.key} scope="col">
              {col.name}
            </th>
          ))}
        </tr>
      </thead>
      <tbody>
        {rows.map(row => (
          <tr key={row.id}>
            {columns.map(col => (
              <td key={col.key}>{row[col.key]}</td>
            ))}
          </tr>
        ))}
      </tbody>
    </table>
  );
}

12. 测试 ​

12.1 测试React Aria组件 ​

typescript
// button.test.tsx
import { render } from '@testing-library/react';
import userEvent from '@testing-library/user-event';
import { Button } from './Button';

describe('Button', () => {
  it('should handle press events', async () => {
    const onPress = jest.fn();
    const { getByRole } = render(
      <Button onPress={onPress}>Click me</Button>
    );
    
    const button = getByRole('button');
    await userEvent.click(button);
    
    expect(onPress).toHaveBeenCalled();
  });
  
  it('should be keyboard accessible', async () => {
    const onPress = jest.fn();
    const { getByRole } = render(
      <Button onPress={onPress}>Click me</Button>
    );
    
    const button = getByRole('button');
    button.focus();
    
    await userEvent.keyboard('{Enter}');
    expect(onPress).toHaveBeenCalled();
  });
});

13. 最佳实践 ​

typescript
const reactAriaBestPractices = {
  usage: [
    '优先使用React Aria提供的Hooks',
    '结合Stately管理状态',
    '使用mergeProps合并多个props',
    '利用FocusScope管理焦点',
    '使用I18nProvider国际化'
  ],
  
  accessibility: [
    '所有交互元素使用usePress而非onClick',
    '为自定义组件添加适当的ARIA属性',
    '使用useFocusRing提供焦点指示器',
    '模态框使用useModal和useOverlay',
    '表单使用专门的表单Hooks'
  ],
  
  performance: [
    '按需导入Hooks',
    '避免不必要的重渲染',
    '使用useObjectRef优化ref',
    '合理使用useMemo和useCallback',
    '大列表使用虚拟化'
  ],
  
  customization: [
    '保持可访问性同时自定义样式',
    '使用className而非内联样式',
    '支持主题定制',
    '提供足够的视觉反馈',
    '确保键盘和触摸交互一致'
  ]
};

14. 与其他库对比 ​

typescript
const libraryComparison = {
  ReactAria: {
    pros: [
      '完整的可访问性支持',
      '细粒度的Hooks',
      '无样式,完全可定制',
      '国际化支持',
      'Adobe官方维护'
    ],
    cons: [
      '需要自己实现样式',
      '学习曲线较陡',
      '组件需要手动组装'
    ]
  },
  
  HeadlessUI: {
    pros: [
      '简单易用',
      'Tailwind团队维护',
      '开箱即用的组件'
    ],
    cons: [
      '功能相对有限',
      '定制性不如React Aria',
      '不支持国际化'
    ]
  },
  
  RadixUI: {
    pros: [
      '无样式组件',
      '良好的可访问性',
      '简洁的API'
    ],
    cons: [
      '组件数量较少',
      '国际化支持有限'
    ]
  }
};

15. 总结 ​

React Aria的关键优势:

  1. 完整可访问性: 实现了ARIA规范和最佳实践
  2. 细粒度控制: 提供底层Hooks,完全可定制
  3. 国际化: 内置国际化支持
  4. 跨平台: 支持Web、移动端、桌面
