Firebase Express SDK

Simplify interaction with Firebase Firestore by using this SDK to easily set up and manage CRUD operations for collections, handle API endpoints, and streamline data retrieval and manipulation in your Express.js projects.

Quick Start

Set up an Express server

mkdir firebase-express-tutorial
cd firebase-express-tutorial

npm init -y

Install the dependencies

npm install express cors body-parser
npm install -D nodemon

Install the Firebase Express SDK:

npm install firebase-express-sdk

Create a new file named index.js and add the following code:

const express = require("express");
const cors = require("cors");
const bodyParser = require("body-parser");
const { FirebaseExpressSdk } = require("firebase-express-sdk");

// We will be back to this later

Create a Firebase project

Go to the Firebase console and create a new project.

Add Cloud Firestore to your project.

For more details about setting up Cloud Firestore, check out the official documentation.

Generate a service account

Go to the service accounts page and generate a new private key.

Save the file in your project directory and name it serviceAccount.json.

The project directory should look like this:

.
├── node_modules
├── serviceAccount.json
├── index.js
├── package.json
└── package-lock.json

Initialize the Firebase Express SDK

Add the following code to the index.js file:

const express = require("express");
const cors = require("cors");
const bodyParser = require("body-parser");
const { FirebaseExpressSdk } = require("firebase-express-sdk");
const serviceAccountFile = require("./serviceAccount.json");

const app = express();
const port = 3001;

app.use(cors());
app.use(bodyParser.json());

const collections = {
  users: {
    documentAttributes: ["name", "age", "email"],
  },
};

const firebaseExpressSdk = new FirebaseExpressSdk({
  app, // Express app
  serviceAccountFile, // Firebase service account file
  collections, // Collections to expose,
  port, // Port to listen to (default: 3000)
});

firebaseExpressSdk.addActions([
  {
    collection: "users",
    endpoint: "/api/getUsers",
    request: {
      type: "GET",
    },
  },
  {
    collection: "users",
    endpoint: "/api/addUser",
    request: {
      type: "POST",
    },
  },
]);

Start the server

Add the following script to the package.json file:

"scripts": {
  "start": "nodemon index.js"
}

Start the server:

npm start

Test the endpoints and enjoy!

Make a GET request to http://localhost:3000/api/getUsers and you should get an empty array.

Make a POST request to http://localhost:3000/api/addUser with the following body:

{
  "name": "John Doe",
  "age": 25,
  "email": "johndoe@john.com"
}

Make a GET request to http://localhost:3000/api/getUsers and you should get the following response:

{
  "status": "success",
  "data": [
    {
      "name": "John Doe",
      "age": 25,
      "email": "johndoe@john.com"
    }
  ]
}
