Electronic Health Record (EHR) Backend

Welcome to the backend repository of our Electronic Health Record (EHR) application. This backend component serves as the server-side logic and database management system for the EHR application.

Introduction

This backend repository houses the server-side codebase responsible for handling authentication, managing user data, and serving API endpoints to the frontend application.

Features

• User Authentication: Secure authentication system using Google OAuth and OTP verification with Amazon SES.
• Role-based Access Control: Different access levels for hospital administrators, patients, and doctors.
• Database Management: Storage and management of patient records, treatment details, and medical history.
• RESTful API: Provides endpoints for CRUD operations on user data, medical records, and other application entities.
• File Storage Bucket: Secure storage for saving records such as X-rays, scans, and other medical documents.
• Integration with Frontend: Seamless integration with the frontend application for a complete EHR solution.

Tech Stack

• Node.js: JavaScript runtime for building server-side applications.
• Express.js: Minimalist web framework for building RESTful APIs.
• TypeScript (TS): Typed superset of JavaScript for improved code quality and developer experience.
• PostgreSQL: Relational database for storing application data.
• Superbase: Hosted PostgreSQL database with built-in authentication and real-time capabilities.
• Passport.js: Authentication middleware for Node.js applications, used for Google OAuth integration.
• JSON Web Tokens (JWT): Used for authentication and authorization of API requests.

Setup Instructions

To set up the backend locally, follow these steps:

1. Clone this repository to your local machine.
2. Install dependencies using npm install.
3. Create a PostgreSQL database instance, either locally or using a cloud service like Superbase.
4. Set up environment variables in a .env file with the following details:

   PORT=6969
   DB_USER=<database-username>
   DB_PASS=<database-password>
   DB_NAME=<database-name>
   DB_HOST=<database-host>
   TEST_MSG=:bitspace
   DOCTOR_SECRET=<doctor-secret>
   HOSPITAL_SECRET=<hospital-secret>
   PATIENT_SECRET=<patient-secret>
   SECURE=f
   ACCESS_KEY=<aws-access-key>
   SECRET_ACCESS_KEY=<aws-secret-access-key>
   REGION=<aws-region>
   VERIFIED_EMAIL=<verified-email>
   PY_URL=<python-api-url>
   

5. Build the server (for typescript) using npm run build.
6. Run the server using npm run dev for development mode.
7. Access the API endpoints at http://localhost:3000 or the specified port.
