批量提交文档到Google Firestore数据库，node.js和promise issue

npm install firebase-admin

const admin = require('firebase-admin');

// 初始化Firebase Admin SDK
admin.initializeApp({
  credential: admin.credential.applicationDefault(),
  databaseURL: 'https://your-database-url.firebaseio.com'
});

const db = admin.firestore();

// 要批量提交的文档数据
const documents = [
  { id: '1', name: 'Alice', age: 30 },
  { id: '2', name: 'Bob', age: 25 },
  { id: '3', name: 'Charlie', age: 35 }
];

// 创建一个批量写入实例
const batch = db.batch();

documents.forEach(doc => {
  const ref = db.collection('users').doc(doc.id);
  batch.set(ref, doc);
});

// 提交批量写入
batch.commit()
  .then(() => {
    console.log('批量提交成功');
  })
  .catch(err => {
    console.error('批量提交失败:', err);
  });

const batchSize = 100; // 每批提交的最大文档数

function batchSubmit(documents) {
  const batches = Math.ceil(documents.length / batchSize);

  for (let i = 0; i < batches; i++) {
    const start = i * batchSize;
    const end = start + batchSize;
    const batchDocuments = documents.slice(start, end);

    const batch = db.batch();

    batchDocuments.forEach(doc => {
      const ref = db.collection('users').doc(doc.id);
      batch.set(ref, doc);
    });

    batch.commit()
      .then(() => {
        console.log(`第${i + 1}批提交成功`);
      })
      .catch(err => {
        console.error(`第${i + 1}批提交失败:`, err);
      });
  }
}

batchSubmit(documents);
