The official Firebase JavaScript SDK providing client-side libraries for Firebase services such as Authentication, Realtime Database, Firestore, Storage, and Cloud Messaging. It is distributed via npm and CDN for use in web apps, Node.js, and other JavaScript environments.

Use cases

• add user sign-in with email and social providers to a web app
• store and sync app data in realtime across clients
• send push notifications to browsers via cloud messaging
• upload and serve user files like images from cloud storage
• connect a Node.js or IoT client to Firebase services
• build a serverless web app backed by Google's Firebase platform

When to choose

• you are building a web or Node.js app on the Firebase platform
• you want managed authentication, realtime database, and messaging without running your own backend
• you need a tree-shakable modular SDK for modern JavaScript bundlers

When to avoid

• you self-host your infrastructure and want to avoid vendor lock-in to Google Cloud
• you need a backend-agnostic database driver for non-Firebase databases
• your project requires a permissively licensed dependency, since the license is custom
