Firebase Auto CRUD API

firecrudnewapi is an NPM package that automatically generates a fully functional CRUD API for Firebase Firestore collections, making backend development fast and efficient. The package provides RESTful endpoints for creating, reading, updating, and deleting data, with support for custom routes.

Features

• Automatically generate CRUD API for Firebase Firestore collections.
• Custom routes to extend beyond basic CRUD.
• Bulk operations for batch updates and deletions.
• Schema enforcement for structuring data.
• Easy-to-use and flexible for various Firebase applications.

Installation

npm install firecrudnewapi

Usage

Here’s how you can quickly set up your Firebase-based CRUD API.

1. Initialize Firebase and Create API

const { createFirebaseCrudAPI } = require('firecrudnewapi');
const serviceAccount = require('./serviceAccountKey.json'); // Firebase service account file
const databaseURL = 'https://your-firebase-project.firebaseio.com'; // Your Firebase database URL

// Define your schema for the Firestore collection
const productSchema = {
  name: '',
  price: 0,
  category: '',
};

// Initialize the CRUD API for Firebase with the collection name "products"
const app = createFirebaseCrudAPI(serviceAccount, databaseURL, 'products', productSchema);

// Start your Express app
app.listen(3000, () => {
  console.log('Firebase CRUD API is running on port 3000');
});

2. Schema Definition

Define a schema for structuring your collection's documents:

const productSchema = {
  name: '',       // Default value for name
  price: 0,       // Default value for price
  category: '',   // Default value for category
};

The schema helps in structuring the documents with default values when creating or updating data.

3. Custom Routes

You can add custom routes to extend the functionality of the basic CRUD API. For example, to get expensive products:

const customRoutes = [
  {
    method: 'get',
    path: '/api/products/expensive',
    handler: async (req, res) => {
      try {
        const expensiveProducts = await firestore.collection('products').where('price', '>', 1000).get();
        const results = expensiveProducts.docs.map(doc => ({ id: doc.id, ...doc.data() }));
        res.status(200).send(results);
      } catch (error) {
        res.status(500).send(error);
      }
    },
  },
];

Pass customRoutes when initializing the CRUD API:

const app = createFirebaseCrudAPI(serviceAccount, databaseURL, 'products', productSchema, customRoutes);

API Endpoints

The package auto-generates the following endpoints for each collection:

1. Create: POST /api

• Creates a new document in the Firestore collection.
• Example:

  {
    "name": "Product A",
    "price": 100,
    "category": "Electronics"
  }

2. Read All: GET /api

• Retrieves all documents from the Firestore collection.
• Supports filtering, sorting, and pagination.

3. Read One: GET /api/:id

• Retrieves a specific document by its ID.

4. Update: PUT /api/:id

• Updates a specific document by its ID.

5. Delete: DELETE /api/:id

• Deletes a specific document by its ID.

6. Bulk Update: POST /api/bulk-update

• Updates multiple documents at once.
• Example request:

  {
    "updates": [
      { "id": "docId1", "data": { "name": "Updated Product A" } },
      { "id": "docId2", "data": { "price": 200 } }
    ]
  }

7. Bulk Delete: POST /api/bulk-delete

• Deletes multiple documents at once.
• Example request:

  {
    "ids": ["docId1", "docId2", "docId3"]
  }

How to Use Custom Libraries

You can use any additional libraries in your custom routes, such as moment for date handling:

const moment = require('moment');

const customRoutes = [
  {
    method: 'get',
    path: '/api/products/recent',
    handler: async (req, res) => {
      const now = moment().subtract(30, 'days').toDate();  // Get products from last 30 days
      const recentProducts = await firestore.collection('products').where('createdAt', '>', now).get();
      const results = recentProducts.docs.map(doc => ({ id: doc.id, ...doc.data() }));
      res.status(200).send(results);
    },
  },
];

Dependencies

• express: Used to create the server and handle routes.
• body-parser: Middleware to parse incoming request bodies.
• firebase-admin: The official Firebase Admin SDK to interact with Firestore.
