## What it is
The Firebase Admin Node.js SDK is the official server-side library for accessing Firebase services (Authentication, Realtime Database, Cloud Messaging, Firestore, Cloud Storage) from privileged environments. It lets backend code perform admin-privileged operations like minting and verifying auth tokens, managing users, and sending push notifications.

## Use cases
- verify firebase id tokens on my node.js server
- send firebase cloud messaging push notifications from backend
- manage firebase auth users programmatically
- read and write realtime database with admin privileges
- mint custom firebase auth tokens
- build an admin console to look up user data
- access firestore and cloud storage from a server

## When to choose
- you need privileged server-side access to Firebase services in Node.js
- you want to verify Firebase auth tokens or manage users from a backend
- you need to send FCM messages without using the FCM server protocols directly

## When to avoid
- you are building a client-side or end-user app (use the Firebase client JavaScript SDK instead)
- your project does not use Firebase
- you need a Node.js version below 22
