组件开发实战

基础组件开发示例

// button组件示例
import React from 'react';
import { View, Text } from '@tarojs/components';
import classNames from 'classnames';
import './index.scss';

export interface ButtonProps {
  /** 按钮类型 */
  type?: 'primary' | 'default' | 'danger';
  /** 按钮尺寸 */
  size?: 'large' | 'medium' | 'small';
  /** 是否禁用 */
  disabled?: boolean;
  /** 点击事件 */
  onClick?: (event: any) => void;
  /** 自定义类名 */
  className?: string;
  /** 子元素 */
  children?: React.ReactNode;
}

export const Button: React.FC<ButtonProps> = ({
  type = 'default',
  size = 'medium',
  disabled = false,
  onClick,
  className,
  children,
}) => {
  const handleClick = (event: any) => {
    if (!disabled && onClick) {
      onClick(event);
    }
  };

  const classes = classNames(
    'btn',
    `btn--${type}`,
    `btn--${size}`,
    {
      'btn--disabled': disabled,
    },
    className
  );

  return (
    <View className={classes} onClick={handleClick}>
      <Text className="btn__text">{children}</Text>
    </View>
  );
};

// 类型导出
export type { ButtonProps };

样式文件结构

// variables.scss - 主题变量定义
$color-primary: #007bff;
$color-success: #28a745;
$color-danger: #dc3545;
$color-warning: #ffc107;

$font-size-base: 14px;
$font-size-lg: 16px;
$font-size-sm: 12px;

$spacing-xs: 4px;
$spacing-sm: 8px;
$spacing-md: 16px;
$spacing-lg: 24px;

// mixins.scss - 样式复用
@mixin button-variant($background, $color, $border) {
  background-color: $background;
  color: $color;
  border: 1px solid $border;
  
  &:hover:not(.btn--disabled) {
    background-color: darken($background, 10%);
  }
}

@mixin button-size($padding, $font-size) {
  padding: $padding;
  font-size: $font-size;
}

// button.scss - 组件样式
.btn {
  display: inline-flex;
  align-items: center;
  justify-content: center;
  border-radius: 4px;
  cursor: pointer;
  transition: all 0.3s ease;
  
  &--primary {
    @include button-variant($color-primary, #fff, $color-primary);
  }
  
  &--default {
    @include button-variant(transparent, #333, #d9d9d9);
  }
  
  &--danger {
    @include button-variant($color-danger, #fff, $color-danger);
  }
  
  &--large {
    @include button-size($spacing-lg $spacing-xl, $font-size-lg);
  }
  
  &--medium {
    @include button-size($spacing-md $spacing-lg, $font-size-base);
  }
  
  &--small {
    @include button-size($spacing-sm $spacing-md, $font-size-sm);
  }
  
  &--disabled {
    opacity: 0.6;
    cursor: not-allowed;
  }
  
  &__text {
    line-height: 1;
  }
}

多端适配策略

平台差异处理

// platform-utils.ts
import { isWeapp, isH5, isRN } from '@tarojs/taro';

export const getPlatformStyle = (styles: {
  weapp?: any;
  h5?: any;
  rn?: any;
  default?: any;
}) => {
  if (isWeapp && styles.weapp) {
    return styles.weapp;
  }
  if (isH5 && styles.h5) {
    return styles.h5;
  }
  if (isRN && styles.rn) {
    return styles.rn;
  }
  return styles.default || {};
};

// 使用示例
export const Button = (props: ButtonProps) => {
  const platformStyles = getPlatformStyle({
    weapp: { padding: '16rpx 32rpx' },
    h5: { padding: '8px 16px' },
    rn: { padding: 12 },
    default: { padding: '12px 24px' }
  });
  
  return <View style={platformStyles}>{props.children}</View>;
};

组件管理机制

// component-manager.ts
import { Button } from './button';
import { Input } from './input';
import { Modal } from './modal';

export interface ComponentManager {
  Button: typeof Button;
  Input: typeof Input;
  Modal: typeof Modal;
  // 更多组件...
}

export const components: ComponentManager = {
  Button,
  Input,
  Modal,
};

// 类型安全的组件使用
export const useComponent = <K extends keyof ComponentManager>(
  componentName: K
): ComponentManager[K] => {
  return components[componentName];
};

主题系统设计

主题配置结构

// theme/types.ts
export interface Theme {
  colors: {
    primary: string;
    secondary: string;
    success: string;
    danger: string;
    warning: string;
    info: string;
    background: string;
    text: string;
    border: string;
  };
  typography: {
    fontFamily: string;
    fontSize: {
      xs: string;
      sm: string;
      base: string;
      lg: string;
      xl: string;
    };
    fontWeight: {
      normal: number;
      medium: number;
      bold: number;
    };
  };
  spacing: {
    xs: string;
    sm: string;
    md: string;
    lg: string;
    xl: string;
  };
  borderRadius: {
    sm: string;
    md: string;
    lg: string;
  };
}

// 默认主题
export const defaultTheme: Theme = {
  colors: {
    primary: '#007bff',
    secondary: '#6c757d',
    success: '#28a745',
    danger: '#dc3545',
    warning: '#ffc107',
    info: '#17a2b8',
    background: '#ffffff',
    text: '#212529',
    border: '#dee2e6',
  },
  typography: {
    fontFamily: '-apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, sans-serif',
    fontSize: {
      xs: '12px',
      sm: '14px',
      base: '16px',
      lg: '18px',
      xl: '20px',
    },
    fontWeight: {
      normal: 400,
      medium: 500,
      bold: 700,
    },
  },
  spacing: {
    xs: '4px',
    sm: '8px',
    md: '16px',
    lg: '24px',
    xl: '32px',
  },
  borderRadius: {
    sm: '2px',
    md: '4px',
    lg: '8px',
  },
};

主题上下文提供

// ThemeProvider.tsx
import React, { createContext, useContext } from 'react';
import { Theme, defaultTheme } from './theme/types';

interface ThemeContextType {
  theme: Theme;
  setTheme: (theme: Theme) => void;
}

const ThemeContext = createContext<ThemeContextType>({
  theme: defaultTheme,
  setTheme: () => {},
});

export const useTheme = () => useContext(ThemeContext);

export const ThemeProvider: React.FC<{
  theme?: Theme;
  children: React.ReactNode;
}> = ({ theme = defaultTheme, children }) => {
  const [currentTheme, setCurrentTheme] = React.useState(theme);

  return (
    <ThemeContext.Provider
      value={{
        theme: currentTheme,
        setTheme: setCurrentTheme,
      }}
    >
      {children}
    </ThemeContext.Provider>
  );
};

测试策略与质量保障

组件单元测试

// __tests__/button.test.tsx
import React from 'react';
import { render, fireEvent } from '@testing-library/react';
import { Button } from '../button';

describe('Button Component', () => {
  test('renders with children', () => {
    const { getByText } = render(<Button>Click me</Button>);
    expect(getByText('Click me')).toBeInTheDocument();
  });

  test('calls onClick when clicked', () => {
    const handleClick = jest.fn();
    const { getByText } = render(
      <Button onClick={handleClick}>Click me</Button>
    );
    
    fireEvent.click(getByText('Click me'));
    expect(handleClick).toHaveBeenCalledTimes(1);
  });

  test('does not call onClick when disabled', () => {
    const handleClick = jest.fn();
    const { getByText } = render(
      <Button disabled onClick={handleClick}>Click me</Button>
    );
    
    fireEvent.click(getByText('Click me'));
    expect(handleClick).not.toHaveBeenCalled();
  });

  test('applies correct classes based on props', () => {
    const { container } = render(
      <Button type="primary" size="large" disabled>
        Click me
      </Button>
    );
    
    const button = container.firstChild;
    expect(button).toHaveClass('btn', 'btn--primary', 'btn--large', 'btn--disabled');
  });
});

构建与发布流程

Rollup配置示例

// rollup.config.mjs
import resolve from '@rollup/plugin-node-resolve';
import commonjs from '@rollup/plugin-commonjs';
import typescript from '@rollup/plugin-typescript';
import postcss from 'rollup-plugin-postcss';
import { terser } from 'rollup-plugin-terser';
import dts from 'rollup-plugin-dts';

export default [
  {
    input: 'src/index.ts',
    output: [
      {
        file: 'dist/index.js',
        format: 'cjs',
        exports: 'named',
      },
      {
        file: 'dist/index.esm.js',
        format: 'esm',
      },
    ],
    plugins: [
      resolve(),
      commonjs(),
      typescript({
        tsconfig: './tsconfig.json',
        declaration: false,
      }),
      postcss({
        extract: true,
        minimize: true,
        modules: true,
      }),
      terser(),
    ],
    external: ['react', 'react-dom', '@tarojs/taro', '@tarojs/components'],
  },
  {
    input: 'dist/types/index.d.ts',
    output: [{ file: 'dist/index.d.ts', format: 'esm' }],
    plugins: [dts()],
  },
];

版本管理与发布脚本

#!/bin/bash
# scripts/release.sh

set -e

# 版本号更新
VERSION=$(npm version patch --no-git-tag-version)

# 构建
npm run build

# 生成变更日志
npx conventional-changelog -p angular -i CHANGELOG.md -s

# 提交更改
git add .
git commit -m "chore: release v$VERSION"
git tag "v$VERSION"

# 发布到npm
npm publish --access public

echo "✅ Released v$VERSION"

最佳实践与性能优化

组件性能优化

// 使用React.memo避免不必要的重渲染
import React from 'react';

export const MemoizedButton = React.memo(Button, (prevProps, nextProps) => {
  // 自定义比较逻辑
  return (
    prevProps.type === nextProps.type &&
    prevProps.size === nextProps.size &&
    prevProps.disabled === nextProps.disabled &&
    prevProps.children === nextProps.children
  );
});

// 使用useCallback优化事件处理
export const useMemoizedHandler = (handler: Function, deps: any[] = []) => {
  return React.useCallback(handler, deps);
};

按需加载策略

// 组件懒加载
import React, { lazy, Suspense } from 'react';

const LazyModal = lazy(() => import('./modal'));

export const App = () => {
  return (
    <Suspense fallback={<div>Loading...</div>}>
      <LazyModal />
    </Suspense>
  );
};

// 主题懒加载
export const loadTheme = async (themeName: string) => {
  const theme = await import(`./themes/${themeName}`);
  return theme.default;
};
