⚡ 性能优化

1. 懒加载组件

<template>
  <div class="lazy-progress-container">
    <vue-ellipse-progress
      v-if="isVisible"
      :progress="progress"
      :size="200"
      :color="color"
      :animation="animationConfig"
    />
  </div>
</template>

<script>
export default {
  data() {
    return {
      isVisible: false,
      progress: 75,
      color: '#42b883',
      animationConfig: {
        duration: 1000,
        delay: 0,
      },
    };
  },
  mounted() {
    // 使用 Intersection Observer 实现懒加载
    this.initIntersectionObserver();
  },
  methods: {
    initIntersectionObserver() {
      const observer = new IntersectionObserver(
        (entries) => {
          entries.forEach((entry) => {
            if (entry.isIntersecting) {
              this.isVisible = true;
              observer.unobserve(this.$el);
            }
          });
        },
        { threshold: 0.1 }
      );

      observer.observe(this.$el);
    },
  },
};
</script>

2. 防抖更新

<script>
import { debounce } from 'lodash-es';

export default {
  data() {
    return {
      progress: 0,
      targetProgress: 0,
    };
  },
  created() {
    // 防抖更新进度
    this.debouncedUpdateProgress = debounce(this.updateProgress, 100);
  },
  methods: {
    updateProgress() {
      this.progress = this.targetProgress;
    },

    setProgress(value) {
      this.targetProgress = value;
      this.debouncedUpdateProgress();
    },
  },
};
</script>

3. 减少重渲染

<template>
  <vue-ellipse-progress
    :progress="memoizedProgress"
    :size="size"
    :color="color"
    :key="progressKey"
  />
</template>

<script>
export default {
  props: {
    value: Number,
    size: {
      type: Number,
      default: 200,
    },
    color: {
      type: String,
      default: '#42b883',
    },
  },
  computed: {
    memoizedProgress() {
      // 只有当变化超过 1% 时才更新
      return Math.floor(this.value / 1) * 1;
    },

    progressKey() {
      // 使用 key 强制重新渲染关键变化
      return `${this.memoizedProgress}-${this.size}-${this.color}`;
    },
  },
};
</script>

❓ 常见问题

Q1: 进度条不显示动画？

A: 检查以下几点：

  1. 确保设置了 animation 属性
  2. 检查 progress 值是否正确更新
  3. 确认组件已正确挂载
<vue-ellipse-progress
  :progress="progress"
  :animation="{ duration: 1000, easing: 'ease-out' }"
/>

Q2: 如何实现逆时针进度？

A: 使用 clockwise 属性：

<vue-ellipse-progress :progress="75" :clockwise="-1" />

Q3: 如何自定义起始位置？

A: 使用 angle 属性（以度为单位）：

<vue-ellipse-progress
  :progress="75"
  :angle="-90"  <!-- 从顶部开始 -->
/>

Q4: 进度条在移动端显示异常？

A: 添加响应式处理：

<template>
  <vue-ellipse-progress
    :size="responsiveSize"
    :thickness="responsiveThickness"
    :progress="progress"
  />
</template>

<script>
export default {
  computed: {
    responsiveSize() {
      return window.innerWidth < 768 ? 150 : 200;
    },
    responsiveThickness() {
      return window.innerWidth < 768 ? 4 : 6;
    },
  },
};
</script>

Q5: 如何处理大量进度条的性能问题？

A: 使用虚拟滚动或分页加载：

<template>
  <div class="progress-list">
    <vue-ellipse-progress
      v-for="(item, index) in visibleItems"
      :key="`progress-${index}`"
      :progress="item.progress"
      :size="80"
    />
  </div>
</template>

<script>
export default {
  data() {
    return {
      allItems: [], // 所有数据
      pageSize: 10,
      currentPage: 1,
    };
  },
  computed: {
    visibleItems() {
      const start = (this.currentPage - 1) * this.pageSize;
      const end = start + this.pageSize;
      return this.allItems.slice(start, end);
    },
  },
};
</script>

🌟 最佳实践

1. 组件封装

<!-- ProgressIndicator.vue -->
<template>
  <div class="progress-indicator">
    <vue-ellipse-progress
      :progress="normalizedProgress"
      :size="size"
      :thickness="thickness"
      :color="computedColor"
      :empty-color="emptyColor"
      :animation="animationConfig"
      :line-cap="lineCap"
    >
      <div class="progress-content">
        <slot :progress="normalizedProgress" :status="status">
          <div class="default-content">
            <div class="progress-value">{{ displayValue }}</div>
            <div class="progress-label" v-if="label">{{ label }}</div>
          </div>
        </slot>
      </div>
    </vue-ellipse-progress>
  </div>
</template>

<script>
export default {
  name: 'ProgressIndicator',
  props: {
    value: {
      type: Number,
      required: true,
      validator: (value) => value >= 0 && value <= 100,
    },
    size: {
      type: Number,
      default: 120,
    },
    thickness: {
      type: Number,
      default: 6,
    },
    color: {
      type: [String, Object],
      default: '#42b883',
    },
    emptyColor: {
      type: String,
      default: '#f0f0f0',
    },
    lineCap: {
      type: String,
      default: 'round',
      validator: (value) => ['round', 'butt', 'square'].includes(value),
    },
    label: String,
    animated: {
      type: Boolean,
      default: true,
    },
    duration: {
      type: Number,
      default: 1000,
    },
    colorThresholds: {
      type: Object,
      default: () => ({
        danger: 30,
        warning: 70,
        success: 100,
      }),
    },
  },
  computed: {
    normalizedProgress() {
      return Math.max(0, Math.min(100, this.value));
    },

    status() {
      const { danger, warning } = this.colorThresholds;
      if (this.normalizedProgress < danger) return 'danger';
      if (this.normalizedProgress < warning) return 'warning';
      return 'success';
    },

    computedColor() {
      if (typeof this.color === 'string') {
        const colors = {
          danger: '#ff5252',
          warning: '#f7b731',
          success: '#42b883',
        };
        return colors[this.status] || this.color;
      }
      return this.color;
    },

    displayValue() {
      return `${this.normalizedProgress}%`;
    },

    animationConfig() {
      return this.animated
        ? {
            duration: this.duration,
            easing: 'ease-out',
          }
        : null;
    },
  },
};
</script>

<style scoped>
.progress-indicator {
  display: inline-block;
}

.progress-content {
  display: flex;
  flex-direction: column;
  align-items: center;
  justify-content: center;
  height: 100%;
}

.default-content {
  text-align: center;
}

.progress-value {
  font-size: 1.2em;
  font-weight: bold;
  color: #333;
}

.progress-label {
  font-size: 0.8em;
  color: #666;
  margin-top: 4px;
}
</style>

2. 使用组合式 API (Vue 3)

// useProgress.js
import { ref, computed, watch } from 'vue';

export function useProgress(initialValue = 0, options = {}) {
  const {
    min = 0,
    max = 100,
    step = 1,
    animated = true,
    duration = 1000,
  } = options;

  const currentValue = ref(initialValue);
  const targetValue = ref(initialValue);
  const isAnimating = ref(false);

  const progress = computed(() => {
    const range = max - min;
    const current = Math.max(min, Math.min(max, currentValue.value));
    return ((current - min) / range) * 100;
  });

  const setValue = (value) => {
    targetValue.value = Math.max(min, Math.min(max, value));

    if (animated) {
      animateToTarget();
    } else {
      currentValue.value = targetValue.value;
    }
  };

  const increment = (amount = step) => {
    setValue(currentValue.value + amount);
  };

  const decrement = (amount = step) => {
    setValue(currentValue.value - amount);
  };

  const reset = () => {
    setValue(initialValue);
  };

  const animateToTarget = () => {
    if (isAnimating.value) return;

    isAnimating.value = true;
    const startValue = currentValue.value;
    const endValue = targetValue.value;
    const startTime = Date.now();

    const animate = () => {
      const elapsed = Date.now() - startTime;
      const progress = Math.min(elapsed / duration, 1);

      // 缓动函数
      const easeOutQuart = 1 - Math.pow(1 - progress, 4);

      currentValue.value = startValue + (endValue - startValue) * easeOutQuart;

      if (progress < 1) {
        requestAnimationFrame(animate);
      } else {
        currentValue.value = endValue;
        isAnimating.value = false;
      }
    };

    requestAnimationFrame(animate);
  };

  return {
    currentValue: readonly(currentValue),
    progress: readonly(progress),
    isAnimating: readonly(isAnimating),
    setValue,
    increment,
    decrement,
    reset,
  };
}

3. TypeScript 类型定义

// types/progress.ts
export interface ProgressConfig {
  progress: number;
  size?: number;
  thickness?: number;
  emptyThickness?: number;
  color?: string | GradientConfig;
  emptyColor?: string;
  lineCap?: 'round' | 'butt' | 'square';
  angle?: number;
  clockwise?: 1 | -1;
  animation?: AnimationConfig;
  dot?: DotConfig;
}

export interface GradientConfig {
  radial: boolean;
  colors: Array<{
    color: string;
    offset: string;
  }>;
}

export interface AnimationConfig {
  duration: number;
  easing?: string;
  delay?: number;
}

export interface DotConfig {
  size: number;
  color: string;
  border?: {
    width: number;
    color: string;
  };
}

export interface ProgressTheme {
  primary: string;
  secondary: string;
  success: string;
  warning: string;
  danger: string;
  background: string;
}

4. 测试用例

// tests/ProgressIndicator.test.js
import { mount } from '@vue/test-utils';
import ProgressIndicator from '@/components/ProgressIndicator.vue';

describe('ProgressIndicator', () => {
  test('renders with correct progress value', () => {
    const wrapper = mount(ProgressIndicator, {
      props: { value: 75 },
    });

    expect(wrapper.text()).toContain('75%');
  });

  test('applies correct color based on status', () => {
    const wrapper = mount(ProgressIndicator, {
      props: {
        value: 25,
        colorThresholds: { danger: 30, warning: 70, success: 100 },
      },
    });

    // 应该是危险状态的颜色
    const progressElement = wrapper.findComponent({
      name: 'VueEllipseProgress',
    });
    expect(progressElement.props('color')).toBe('#ff5252');
  });

  test('emits events on value change', async () => {
    const wrapper = mount(ProgressIndicator, {
      props: { value: 50 },
    });

    await wrapper.setProps({ value: 75 });

    // 检查是否触发了相应的事件
    expect(wrapper.emitted()).toHaveProperty('change');
  });
});
