  <title>amis Vue整合示例</title>
  <link rel="stylesheet" href="https://unpkg.com/amis@版本号/sdk/sdk.css">
  <script src="https://unpkg.com/vue@3/dist/vue.global.js"></script>
  <script src="https://unpkg.com/amis@版本号/sdk/sdk.js"></script>
</head>
<body>
  <div id="app">
    <div id="amis-container"></div>
  </div>

  <script>
    const { createApp } = Vue;
    
    const app = createApp({
      mounted() {
        // 初始化amis
        const amis = amisRequire('amis/embed');
        const amisScoped = amis.embed('#amis-container', {
          type: 'page',
          title: 'Vue整合示例',
          body: {
            type: 'form',
            api: '/api/submit',
            body: [
              {
                type: 'input-text',
                name: 'name',
                label: '姓名',
                required: true
              },
              {
                type: 'button',
                label: '提交',
                actionType: 'submit'
              }
            ]
          }
        });
        
        // 存储amis实例供Vue组件使用
        this.$amis = amisScoped;
      },
      methods: {
        updateAmisData(newData) {
          if (this.$amis) {
            this.$amis.updateProps({ data: newData });
          }
        }
      }
    });
    
    app.mount('#app');
  </script>
</body>
</html>

方案特点：

⚡ 快速集成，无需构建配置
📦 依赖外部CDN，适合简单场景
🔗 数据通信通过实例方法调用

方案二：Vue组件包装方案

更适合现代Vue项目工程化集成：

// AmisRenderer.vue
<template>
  <div ref="container" class="amis-container"></div>
</template>

<script>
import { onMounted, onUnmounted, ref, watch } from 'vue';

export default {
  name: 'AmisRenderer',
  props: {
    schema: {
      type: Object,
      required: true
    },
    data: {
      type: Object,
      default: () => ({})
    }
  },
  emits: ['update:data', 'event'],
  setup(props, { emit }) {
    const container = ref(null);
    let amisInstance = null;

    const initAmis = async () => {
      if (typeof amisRequire !== 'function') {
        // 动态加载amis SDK
        await loadAmisSDK();
      }
      
      const amis = amisRequire('amis/embed');
      amisInstance = amis.embed(container.value, {
        ...props.schema,
        data: props.data
      }, {
        // 事件监听器
        onEvent: (event, data) => {
          emit('event', { event, data });
        }
      });
    };

    const loadAmisSDK = () => {
      return new Promise((resolve) => {
        if (document.getElementById('amis-sdk')) {
          resolve();
          return;
        }

        // 加载CSS
        const cssLink = document.createElement('link');
        cssLink.rel = 'stylesheet';
        cssLink.href = 'https://unpkg.com/amis@版本号/sdk/sdk.css';
        document.head.appendChild(cssLink);

        // 加载JS
        const jsScript = document.createElement('script');
        jsScript.id = 'amis-sdk';
        jsScript.src = 'https://unpkg.com/amis@版本号/sdk/sdk.js';
        jsScript.onload = resolve;
        document.head.appendChild(jsScript);
      });
    };

    onMounted(() => {
      initAmis();
    });

    onUnmounted(() => {
      if (amisInstance) {
        amisInstance.unmount();
      }
    });

    watch(() => props.data, (newData) => {
      if (amisInstance) {
        amisInstance.updateProps({ data: newData });
      }
    }, { deep: true });

    return {
      container
    };
  }
};
</script>

<style scoped>
.amis-container {
  min-height: 400px;
}
</style>

使用示例：

<template>
  <div>
    <h1>Vue应用整合amis</h1>
    <AmisRenderer 
      :schema="amisSchema" 
      :data="formData"
      @event="handleAmisEvent"
      @update:data="updateFormData"
    />
    
    <div class="vue-section">
      <h2>Vue控制区</h2>
      <input v-model="vueInput" placeholder="从Vue输入数据">
      <button @click="syncToAmis">同步到amis</button>
    </div>
  </div>
</template>

<script>
import { ref, reactive } from 'vue';
import AmisRenderer from './AmisRenderer.vue';

export default {
  components: { AmisRenderer },
  setup() {
    const vueInput = ref('');
    const formData = reactive({
      name: '',
      email: ''
    });

    const amisSchema = {
      type: 'form',
      title: '用户信息表单',
      mode: 'horizontal',
      api: '/api/submit',
      body: [
        {
          type: 'input-text',
          name: 'name',
          label: '姓名',
          required: true
        },
        {
          type: 'input-email',
          name: 'email',
          label: '邮箱',
          required: true
        },
        {
          type: 'button',
          label: '提交',
          actionType: 'submit'
        }
      ]
    };

    const handleAmisEvent = (eventData) => {
      console.log('amis事件:', eventData);
      // 处理amis发出的事件
    };

    const updateFormData = (newData) => {
      Object.assign(formData, newData);
    };

    const syncToAmis = () => {
      formData.name = vueInput.value;
    };

    return {
      amisSchema,
      formData,
      vueInput,
      handleAmisEvent,
      updateFormData,
      syncToAmis
    };
  }
};
</script>

方案三：深度定制整合方案

对于需要深度定制的企业级应用，推荐使用Render Prop模式：

// advanced-amis-integration.js
import { createApp, ref, onMounted } from 'vue';

class AmisVueBridge {
  constructor(vueApp) {
    this.vueApp = vueApp;
    this.components = new Map();
    this.init();
  }

  init() {
    // 注册全局amis组件
    this.vueApp.config.globalProperties.$amis = {
      register: (name, component) => {
        this.components.set(name, component);
      },
      resolveComponent: (name) => {
        return this.components.get(name);
      }
    };
  }

  createCustomRenderer(config) {
    return {
      renderer: {
        test: config.test,
        component: config.component
      },
      vueComponent: config.vueComponent
    };
  }
}

// 自定义Vue组件映射到amis
const vueComponentMap = {
  'vue-date-picker': {
    component: VueDatePicker,
    propsMapper: (amisProps) => ({
      modelValue: amisProps.value,
      'onUpdate:modelValue': amisProps.onChange
    })
  }
};

export function createAmisVueApp(App, options = {}) {
  const app = createApp(App);
  const bridge = new AmisVueBridge(app);

  // 注册所有Vue组件到amis
  Object.entries(vueComponentMap).forEach(([type, config]) => {
    bridge.registerAmisComponent(type, config);
  });

  return { app, bridge };
}

三、双向数据绑定实现

实现Vue和amis之间的双向数据同步是关键挑战：

// bidirectional-binding.js
export function createAmisVueBinder(vueRef, amisInstance) {
  let isUpdating = false;

  // Vue -> amis 数据同步
  const syncToAmis = (newValue) => {
    if (!isUpdating && amisInstance) {
      isUpdating = true;
      amisInstance.updateProps({ data: newValue });
      setTimeout(() => { isUpdating = false; }, 50);
    }
  };

  // amis -> Vue 数据同步
  const syncToVue = (newData) => {
    if (!isUpdating) {
      isUpdating = true;
      Object.assign(vueRef.value, newData);
      setTimeout(() => { isUpdating = false; }, 50);
    }
  };

  // 监听amis数据变化
  if (amisInstance) {
    const originalUpdateProps = amisInstance.updateProps;
    amisInstance.updateProps = function(props) {
      if (props.data && !isUpdating) {
        syncToVue(props.data);
      }
      return originalUpdateProps.call(this, props);
    };
  }

  return {
    syncToAmis,
    syncToVue,
    destroy: () => {
      isUpdating = false;
    }
  };
}

四、自定义组件开发指南

4.1 Vue组件适配amis

<template>
  <div class="vue-amis-component">
    <h3>{{ title }}</h3>
    <slot name="default">
      <p>默认内容</p>
    </slot>
    <button @click="handleClick">点击我</button>
  </div>
</template>

<script>
export default {
  name: 'VueAmisComponent',
  props: {
    title: {
      type: String,
      default: 'Vue组件'
    },
    value: {
      type: [String, Number, Object],
      default: ''
    }
  },
  emits: ['change', 'event'],
  methods: {
    handleClick() {
      this.$emit('change', 'new-value');
      this.$emit('event', {
        type: 'click',
        data: { value: this.value }
      });
    }
  }
};
</script>

4.2 amis包装器组件

// AmisVueWrapper.jsx
import React, { useEffect, useRef } from 'react';
import { Renderer } from 'amis';

export const AmisVueWrapper = React.memo((props) => {
  const containerRef = useRef(null);
  const vueInstanceRef = useRef(null);

  useEffect(() => {
    if (containerRef.current && typeof Vue !== 'undefined') {
      const { value, onChange, ...vueProps } = props;
      
      // 创建Vue应用
      const app = Vue.createApp({
        template: `
          <vue-amis-component 
            :title="title" 
            :value="value"
            @change="handleChange"
            @event="handleEvent"
          />
        `,
        components: {
          VueAmisComponent: window.VueAmisComponent
        },
        data() {
          return {
            title: vueProps.title,
            value: value
          };
        },
        methods: {
          handleChange(newValue) {
            onChange?.(newValue);
          },
          handleEvent(event) {
            props.onEvent?.(event);
          }
        }
      });

      vueInstanceRef.current = app.mount(containerRef.current);
    }

    return () => {
      if (vueInstanceRef.current) {
        vueInstanceRef.current.unmount();
      }
    };
  }, []);

  useEffect(() => {
    if (vueInstanceRef.current) {
      vueInstanceRef.current.value = props.value;
    }
  }, [props.value]);

  return <div ref={containerRef} />;
});

// 注册为amis组件
Renderer({
  type: 'vue-wrapper'
})(AmisVueWrapper);

五、性能优化策略

5.1 组件懒加载

// lazy-amis-loader.js
export function createLazyAmisLoader() {
  let amisLoaded = false;
  const loadCallbacks = [];

  const loadAmis = async () => {
    if (amisLoaded) return true;

    return new Promise((resolve) => {
      // 预加载资源
      const resources = [
        'https://unpkg.com/amis@版本号/sdk/sdk.css',
        'https://unpkg.com/amis@版本号/sdk/sdk.js'
      ];

      let loadedCount = 0;
      
      resources.forEach((url) => {
        if (url.endsWith('.css')) {
          const link = document.createElement('link');
          link.rel = 'stylesheet';
          link.href = url;
          link.onload = checkAllLoaded;
          document.head.appendChild(link);
        } else {
          const script = document.createElement('script');
          script.src = url;
          script.onload = checkAllLoaded;
          document.head.appendChild(script);
        }
      });

      function checkAllLoaded() {
        loadedCount++;
        if (loadedCount === resources.length) {
          amisLoaded = true;
          resolve(true);
          loadCallbacks.forEach(callback => callback());
          loadCallbacks.length = 0;
        }
      }
    });
  };

  return {
    loadAmis,
    onAmisLoaded: (callback) => {
      if (amisLoaded) {
        callback();
      } else {
        loadCallbacks.push(callback);
      }
    }
  };
}

5.2 虚拟滚动优化

<template>
  <div class="virtual-amis-container">
    <div 
      class="amis-viewport" 
      ref="viewport"
      @scroll="handleScroll"
    >
      <div :style="contentStyle">
        <AmisRenderer
          v-for="item in visibleItems"
          :key="item.id"
          :schema="item.schema"
          :data="item.data"
        />
      </div>
    </div>
  </div>
</template>

<script>
import { ref, computed, onMounted } from 'vue';

export default {
  props: {
    items: Array,
    itemHeight: {
      type: Number,
      default: 100
    }
  },
  setup(props) {
    const viewport = ref(null);
    const scrollTop = ref(0);
    const viewportHeight = ref(0);

    const visibleRange = computed(() => {
      const start = Math.floor(scrollTop.value / props.itemHeight);
      const end = start + Math.ceil(viewportHeight.value / props.itemHeight) + 2;
      return { start, end };
    });

    const visibleItems = computed(() => {
      const { start, end } = visibleRange.value;
      return props.items.slice(start, end).map((item, index) => ({
        ...item,
        index: start + index
      }));
    });

    const contentStyle = computed(() => ({
      height: `${props.items.length * props.itemHeight}px`,
      paddingTop: `${visibleRange.value.start * props.itemHeight}px`
    }));

    const handleScroll = () => {
      scrollTop.value = viewport.value.scrollTop;
    };

    onMounted(() => {
      viewportHeight.value = viewport.value.clientHeight;
    });

    return {
      viewport,
      visibleItems,
      contentStyle,
      handleScroll
    };
  }
};
</script>

六、企业级最佳实践

6.1 项目结构规划

src/
├── components/
│   ├── amis/
│   │   ├── AmisRenderer.vue          # 主渲染器组件
│   │   ├── AmisBridge.js             # 桥梁层
│   │   └── plugins/                  # amis插件
│   ├── vue-amis/                     # Vue-amsi混合组件
│   └── pure-vue/                     # 纯Vue组件
├── schemas/                          # amis JSON Schema
│   ├── forms/                        # 表单schema
│   ├── pages/                        # 页面schema
│   └── components/                   # 组件schema
├── utils/
│   └── amis-utils.js                 # 工具函数
└── types/
    └── amis.d.ts                     # TypeScript类型定义

6.2 类型安全配置

// amis.d.ts
interface AmisSchema {
  type: string;
  [key: string]: any;
}

interface AmisFormSchema extends AmisSchema {
  type: 'form';
  body: AmisSchema[];
  api?: string;
  mode?: 'horizontal' | 'vertical' | 'inline';
}

interface AmisVueComponentProps {
  schema: AmisSchema;
  data?: Record<string, any>;
  onEvent?: (event: AmisEvent) => void;
  onDataChange?: (data: Record<string, any>) => void;
}

interface AmisEvent {
  type: string;
  data: any;
  context: any;
}

// Vue组件props类型定义
export const amisProps = {
  schema: {
    type: Object as PropType<AmisSchema>,
    required: true
  },
  data: {
    type: Object as PropType<Record<string, any>>,
    default: () => ({})
  },
  onEvent: Function as PropType<(event: AmisEvent) => void>,
  onDataChange: Function as PropType<(data: Record<string, any>) => void>
};

七、调试与故障排除

7.1 常见问题解决方案

问题现象	可能原因	解决方案
组件不渲染	amis SDK未加载	检查CDN链接或本地路径
数据不同步	双向绑定冲突	添加防抖机制和更新标志
样式错乱	CSS冲突	添加作用域样式或命名空间
事件不触发	事件监听器配置错误	检查事件名称和参数格式

7.2 调试工具函数

export function createAmisDebugger(namespace = 'amis-vue') {
  const debug = {
    log: (...args) => {
      if (process.env.NODE_ENV === 'development') {
        console.log(`[${namespace}]`, ...args);
      }
    },
    warn: (...args) => {
      console.warn(`[${namespace}]`, ...args);
    },
    error: (...args) => {
      console.error(`[${namespace}]`, ...args);
    },
    trace: (label, data) => {
      if (process.env.NODE_ENV === 'development') {
        console.groupCollapsed(`[${namespace}] ${label}`);
        console.trace(data);
        console.groupEnd();
      }
    }
  };

  return debug;
}

// 使用示例
const debug = createAmisDebugger('my-app');
debug.log('amis实例创建成功', amisInstance);
