在 Nodejs 中为 firebase-admin NPM 初始化到 Firebase 的多个连接失败

Question

I have the following code trying to connect to Firebase Realtime Database in NodeJS using the latest firebase-admin package (10.x):

import { database } from 'firebase-admin';
import { applicationDefault, initializeApp } from 'firebase-admin/app';

const app = initializeApp({
    credential: applicationDefault(),
    databaseURL: 'https://DATABASE_NAME.firebaseio.com'
}, 'xx');

const db = database(app);

The issue is that the database(app) call fails with following error:

TypeError: _this.ensureApp(...).database is not a function

I believe that my code is correct since I need the ability to connect to multiple databases...

Anybody knows what am I doing wrong?

Answer 1

The following import is incorrect:

import { database } from 'firebase-admin';

The correct modular import is:

import { getDatabase } from 'firebase-admin/database';

getDatabase()

Or, if using the old namespaced API:

import * as admin from 'firebase-admin'

admin.database()
