<template>
  <div>
    <input type="text" v-model="searchKeyword">
    <ul>
      <li v-for="item in filteredItems" :key="item.id">{{ item.name }}</li>

<script>
import Fuse from 'fuse.js';
export default {
  data() {
    return {
      items: [
        { id: 1, name: 'Apple' },
        { id: 2, name: 'Banana' },
        { id: 3, name: 'Orange' },
        { id: 4, name: 'Grapes' }
      ],
      searchKeyword: ''
    }
  },
  computed: {
    filteredItems() {
      const fuse = new Fuse(this.items, { keys: ['name'] });
      const result = fuse.search(this.searchKeyword);
      return result.map(item => item.item);
    }
  }
}
</script>

// 后端代码（Node.js + Express.js）
app.get('/items', (req, res) => {
  const searchKeyword = req.query.keyword;
  // 执行模糊查询操作，查询关键字为searchKeyword
  // 返回匹配的结果
});
// 前端代码（Vue.js）
<template>
  <div>
    <input type="text" v-model="searchKeyword">
    <ul>
      <li v-for="item in filteredItems" :key="item.id">{{ item.name }}</li>
    </ul>
  </div>
</template>
<script>
export default {
  data() {
    return {
      items: [],
      searchKeyword: ''
    }
  },
  computed: {
    filteredItems() {
      // 发送请求到后端API，将查询关键字作为参数传递
      // 接收后端返回的匹配结果
    }
  },
  mounted() {
    // 在组件挂载时获取初始数据
    // 可以发送请求到后端API获取所有数据项
  }
}
