我可以在不创建事件的情况下将数据写入firebase吗？

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

// 初始化Firebase应用
const serviceAccount = require('./path/to/serviceAccountKey.json');
admin.initializeApp({
  credential: admin.credential.cert(serviceAccount),
  databaseURL: 'https://your-database-url.firebaseio.com'
});

// 写入数据
const db = admin.database();
const ref = db.ref('users');

ref.set({
  username: 'exampleUser',
  email: 'user@example.com'
}, (error) => {
  if (error) {
    console.log('Data could not be saved:', error);
  } else {
    console.log('Data saved successfully.');
  }
});

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

// 初始化Firebase应用
const serviceAccount = require('./path/to/serviceAccountKey.json');
admin.initializeApp({
  credential: admin.credential.cert(serviceAccount)
});

// 写入数据
const db = admin.firestore();

db.collection('users').doc('user1').set({
  username: 'exampleUser',
  email: 'user@example.com'
}).then(() => {
  console.log('Document successfully written!');
}).catch((error) => {
  console.error('Error writing document: ', error);
});
