在NodeJS中将JSON对象从多个文件插入到MongoDB的最有效方法

const MongoClient = require('mongodb').MongoClient;

const fs = require('fs');

// 读取JSON文件
const file1 = fs.readFileSync('file1.json');
const file2 = fs.readFileSync('file2.json');

// 解析为JavaScript对象
const data1 = JSON.parse(file1);
const data2 = JSON.parse(file2);

const url = 'mongodb://localhost:27017/mydatabase';

MongoClient.connect(url, function(err, client) {
  if (err) throw err;

  const db = client.db('mydatabase');
  const collection = db.collection('mycollection');
  
  // 批量插入数据
  collection.insertMany([data1, data2], function(err, result) {
    if (err) throw err;

    console.log('数据插入成功');
    client.close();
  });
});
