clearfix "> <p>The Admin SDK is a set of server libraries that lets you interact with Firebase from privileged environments to perform actions like:</p> <ul> <li>Read and write Realtime Database data with full admin privileges.</li> <li>Programmatically send Firebase Cloud Messaging messages using a simple, alternative approach to the Firebase Cloud Messaging server protocols.</li> <li>Generate and verify Firebase auth tokens.</li> <li>Access Google Cloud resources like Cloud Storage buckets and Cloud Firestore databases associated with your Firebase projects.</li> <li>Create your own simplified admin console to do things like look up user data or change a user's email address for authentication.</li> </ul> <p>If you are interested in using the Node.js SDK as a client for end-user access (for example, in a Node.js desktop or IoT application), as opposed to admin access from a privileged environment (like a server), you should instead follow the <a href="/web/20210428194054/https://firebase.google.com/docs/web/setup">instructions for setting up the client JavaScript SDK</a>.</p> <p>Here is a feature matrix showing what Firebase features are
