Anime.js核心架构解析

模块化设计理念

Anime.js V4采用ES模块化架构，提供了清晰的API边界和出色的Tree Shaking支持：

// 按需导入所需模块
import { animate, timeline, stagger, spring } from 'animejs'

Vue.js集成策略

组合式API集成模式

import { ref, computed, watch, onUnmounted } from 'vue'
import { animate, timeline } from 'animejs'

export function useAnimeAnimation(targetRef, options) {
  const animation = ref(null)
  const isPlaying = ref(false)
  
  const setupAnimation = () => {
    if (animation.value) {
      animation.value.pause()
    }
    
    animation.value = animate(targetRef.value, {
      ...options,
      autoplay: false,
      complete: () => isPlaying.value = false
    })
  }
  
  watch(targetRef, setupAnimation, { immediate: true })
  
  const play = () => {
    if (animation.value) {
      animation.value.play()
      isPlaying.value = true
    }
  }
  
  const pause = () => {
    if (animation.value) {
      animation.value.pause()
      isPlaying.value = false
    }
  }
  
  onUnmounted(() => {
    if (animation.value) {
      animation.value.pause()
    }
  })
  
  return {
    play,
    pause,
    isPlaying
  }
}

实战：构建响应式动画系统

基础集成示例

<template>
  <div ref="animatedElement" class="box" :class="{ 'is-active': isActive }">
    {{ message }}
  </div>
  <button @click="toggleAnimation">Toggle Animation</button>
</template>

<script setup>
import { ref, onMounted, watch } from 'vue'
import { animate } from 'animejs'

const animatedElement = ref(null)
const isActive = ref(false)
const animationInstance = ref(null)

const setupAnimation = () => {
  if (!animatedElement.value) return
  
  animationInstance.value = animate(animatedElement.value, {
    translateX: 250,
    rotate: '1turn',
    backgroundColor: '#FFF',
    duration: 800,
    easing: 'easeInOutQuad',
    autoplay: false,
    complete: () => console.log('Animation completed')
  })
}

const toggleAnimation = () => {
  isActive.value = !isActive.value
  if (animationInstance.value) {
    if (isActive.value) {
      animationInstance.value.play()
    } else {
      animationInstance.value.reverse()
    }
  }
}

onMounted(setupAnimation)
watch(animatedElement, setupAnimation)
</script>

高级时间线管理

import { timeline } from 'animejs'

export function useComplexAnimation(sceneRef) {
  const masterTimeline = timeline({ autoplay: false })
  const animationState = ref('idle')
  
  const scenes = {
    intro: timeline()
      .add(sceneRef.value, { opacity: [0, 1], duration: 1000 })
      .add(sceneRef.value, { scale: [0.8, 1], duration: 800 }, '-=200'),
    
    main: timeline()
      .add(sceneRef.value, { rotate: 360, duration: 2000 })
      .add(sceneRef.value, { backgroundColor: '#ff6b6b' }, '-=1000'),
    
    outro: timeline()
      .add(sceneRef.value, { opacity: 0, duration: 600 })
  }
  
  masterTimeline
    .add(scenes.intro)
    .add(scenes.main)
    .add(scenes.outro)
  
  const playScene = (sceneName) => {
    const sceneTime = masterTimeline.labels[sceneName]
    if (sceneTime !== undefined) {
      masterTimeline.seek(sceneTime)
      animationState.value = sceneName
    }
  }
  
  return {
    play: () => masterTimeline.play(),
    pause: () => masterTimeline.pause(),
    playScene,
    animationState
  }
}

响应式动画模式

状态驱动动画

export function useStateDrivenAnimation(elementRef, state) {
  const animations = {
    loading: {
      rotate: 360,
      scale: 1.2,
      duration: 1000,
      loop: true,
      easing: 'linear'
    },
    success: {
      scale: [1, 1.5, 1],
      backgroundColor: '#4ecdc4',
      duration: 600,
      easing: 'easeOutElastic'
    },
    error: {
      x: [0, 10, -10, 0],
      backgroundColor: '#ff6b6b',
      duration: 300,
      easing: 'easeInOutQuad'
    }
  }
  
  watch(state, (newState) => {
    if (elementRef.value && animations[newState]) {
      animate(elementRef.value, animations[newState])
    }
  }, { immediate: true })
}

数据绑定动画

export function useDataBoundAnimation(elementRef, dataSource) {
  const previousValue = ref(0)
  
  watch(dataSource, (newValue, oldValue) => {
    const difference = newValue - oldValue
    const direction = difference > 0 ? 1 : -1
    
    animate(elementRef.value, {
      translateY: [30 * direction, 0],
      opacity: [0, 1],
      duration: 300,
      easing: 'easeOutQuad'
    })
    
    previousValue.value = newValue
  })
}

性能优化策略

动画池管理

class AnimationPool {
  constructor() {
    this.pool = new Map()
    this.activeAnimations = new Set()
  }
  
  getAnimation(key, createCallback) {
    if (this.pool.has(key)) {
      return this.pool.get(key)
    }
    
    const animation = createCallback()
    this.pool.set(key, animation)
    return animation
  }
  
  playAnimation(key) {
    const animation = this.pool.get(key)
    if (animation && !this.activeAnimations.has(key)) {
      animation.play()
      this.activeAnimations.add(key)
      
      animation.complete = () => {
        this.activeAnimations.delete(key)
      }
    }
  }
  
  cleanup() {
    this.pool.forEach(animation => animation.pause())
    this.activeAnimations.clear()
  }
}

// Vue composable
export function useAnimationPool() {
  const pool = new AnimationPool()
  
  onUnmounted(() => pool.cleanup())
  
  return {
    get: pool.getAnimation.bind(pool),
    play: pool.playAnimation.bind(pool)
  }
}

内存管理最佳实践

场景	策略	效果
列表动画	对象池复用	减少GC压力
频繁触发	防抖控制	避免过度渲染
复杂场景	分层渲染	优化绘制性能
移动设备	简化效果	保证流畅性

调试与错误处理

动画调试工具

export function useAnimationDebugger(animationInstance, name = 'animation') {
  const states = {
    playing: ref(false),
    progress: ref(0),
    currentTime: ref(0)
  }
  
  const updateDebugInfo = () => {
    if (animationInstance) {
      states.playing.value = !animationInstance.paused
      states.progress.value = animationInstance.progress
      states.currentTime.value = animationInstance.currentTime
    }
  }
  
  // 监听动画状态变化
  const interval = setInterval(updateDebugInfo, 100)
  
  onUnmounted(() => clearInterval(interval))
  
  return {
    ...states,
    log: (message) => console.log(`[${name}]`, message)
  }
}

错误边界处理

export function useSafeAnimation(factory) {
  const error = ref(null)
  const animation = ref(null)
  
  try {
    animation.value = factory()
  } catch (e) {
    error.value = e
    console.warn('Animation creation failed:', e)
  }
  
  const safePlay = () => {
    if (animation.value && !error.value) {
      try {
        animation.value.play()
      } catch (e) {
        console.warn('Animation play failed:', e)
      }
    }
  }
  
  return {
    animation,
    error,
    play: safePlay
  }
}

高级应用场景

手势驱动动画

export function useGestureAnimation(elementRef) {
  const dragX = ref(0)
  const isDragging = ref(false)
  
  const animation = animate(elementRef.value, {
    translateX: dragX,
    scale: computed(() => isDragging.value ? 1.1 : 1),
    duration: 0, // 即时更新
    autoplay: false
  })
  
  const handleDrag = (event) => {
    isDragging.value = true
    dragX.value = event.clientX
    animation.tick()
  }
  
  const handleRelease = () => {
    isDragging.value = false
    // 平滑回到原位
    animate(elementRef.value, {
      translateX: 0,
      scale: 1,
      duration: 300,
      easing: 'easeOutElastic'
    })
  }
  
  return {
    handleDrag,
    handleRelease
  }
}

视差滚动系统

export function useParallaxAnimation(containerRef, elements) {
  const scrollY = ref(0)
  
  const updateParallax = () => {
    const scrollPosition = window.scrollY
    scrollY.value = scrollPosition
    
    elements.forEach(({ element, speed }) => {
      const offset = scrollPosition * speed
      animate(element, {
        translateY: offset,
        duration: 0,
        autoplay: false
      }).tick()
    })
  }
  
  onMounted(() => {
    window.addEventListener('scroll', updateParallax, { passive: true })
    updateParallax()
  })
  
  onUnmounted(() => {
    window.removeEventListener('scroll', updateParallax)
  })
  
  return { scrollY }
}

测试策略

单元测试示例

import { describe, it, expect, vi } from 'vitest'
import { useAnimeAnimation } from './useAnimeAnimation'

describe('useAnimeAnimation', () => {
  it('should create animation instance', () => {
    const mockElement = { style: {} }
    const { animation } = useAnimeAnimation(ref(mockElement), {
      translateX: 100
    })
    
    expect(animation.value).toBeDefined()
  })
  
  it('should handle play/pause states', async () => {
    const { play, pause, isPlaying } = useAnimeAnimation(ref({}))
    
    play()
    expect(isPlaying.value).toBe(true)
    
    pause()
    expect(isPlaying.value).toBe(false)
  })
})

集成测试矩阵

测试类型	覆盖场景	验证点
状态同步	Vue状态变化	动画正确响应
性能基准	多动画并发	帧率稳定性
内存泄漏	组件卸载	资源正确释放
错误恢复	异常情况	优雅降级
