Hospital Patient Registration System - Backend

This is the backend for a hospital patient registration system with authentication, patient registration, and prescription image upload functionality.

Features

• Staff and Admin authentication
• Patient registration with details
• Prescription image upload with compression
• Firebase Storage integration for image storage
• Search and sort functionality for patients
• Pagination for patient listing

Setup Instructions

Prerequisites

• Node.js (v14 or higher)
• MongoDB
• Firebase account

Installation

1. Clone the repository

2. Install dependencies:

   npm install
   

3. Set up Firebase:

   • Create a Firebase project at https://console.firebase.google.com/
   • Go to Project Settings > Service accounts
   • Generate a new private key (this will download a JSON file)
   • Enable Firebase Storage in your project

4. Create a .env file based on env.example:

   • Set your MongoDB connection string
   • Set your JWT secret
   • Set your Firebase credentials. There are two options:
     1. Set the entire Firebase service account JSON as a string in FIREBASE_SERVICE_ACCOUNT, or
     2. Set individual Firebase credentials (FIREBASE_PROJECT_ID, FIREBASE_PRIVATE_KEY, etc.)
   • Set your Firebase storage bucket name
   • Set default admin user credentials for initial setup

Security Considerations

The application has been configured to use environment variables for all sensitive information:

1. Firebase Credentials: No credentials are hardcoded in the code. The Firebase configuration loads all credentials from environment variables.
2. Database Connection: MongoDB connection strings are loaded from environment variables.
3. JWT Secrets: Authentication tokens are signed with a secret stored in environment variables.
4. Admin Creation: Admin credentials are loaded from environment variables instead of being hardcoded.

Make sure to:

• Keep your .env file secure and never commit it to version control
• Use strong, unique passwords for your admin accounts
• Rotate your Firebase service account keys periodically
• Set appropriate Firebase Storage security rules
