Firebase Express SDK is an npm library that connects your Express.js application to Firebase Firestore. Define your collections once and get fully functional GET, POST, PUT, PATCH, and DELETE endpoints — with built-in request validation — without writing repetitive boilerplate.

Quick Start

Install the SDK and have your first Firestore endpoint running in under 5 minutes.

Core Concepts

Understand collections, document attributes, and how actions map to HTTP endpoints.

Guides

Step-by-step walkthroughs for GET, POST, PUT, PATCH, DELETE, filtering, and sorting.

API Reference

Full reference for the constructor options, action config, and response format.

How it works

1

Install the SDK

Add firebase-express-sdk to your Express project with npm.
2

Configure your collections

Define the Firestore collections you want to expose and their document attributes.
3

Add actions

Map HTTP methods and endpoints to your collections with addActions().
4

Start your server

Your Firestore-backed endpoints are live and ready to use.
Firebase Express SDK uses the Firebase Admin SDK under the hood. You need a Firebase service account key to authenticate — see the Quick Start for setup instructions.
