A modern, secure, and HIPAA-compliant healthcare management system built with React, NestJS, and TypeScript.

The application follows a microservices architecture with three main components:

• React + TypeScript
• Vite for build tooling
• Context API for state management
• HIPAA-compliant security measures
• Role-based access control
• Protected health information handling

• NestJS microservice
• JWT-based authentication
• Role-based authorization
• Session management
• Audit logging
• Password security

• NestJS microservice
• Appointment management
• Healthcare provider scheduling
• Patient records
• Audit trails
• PHI protection

1. Authentication & Authorization

   • Secure JWT implementation
   • Role-based access control
   • Session management
   • Password security

2. Data Protection

   • Encryption at rest and in transit
   • PHI data handling
   • Secure data transmission
   • Data access logging

3. Audit & Logging

   • Comprehensive audit trails
   • Access logging
   • Change tracking
   • Error monitoring

4. Security Measures

   • HTTPS enforcement
   • Security headers
   • XSS protection
   • CSRF protection
   • Rate limiting

• Docker and Docker Compose
• Node.js 18+ (for local development)
• npm or yarn

1. Clone the repository:

   git clone https://github.com/your-username/healthcare-app.git
   cd healthcare-app

2. Copy the environment template:

   cp .env.example .env

3. Update the .env file with your secure values

4. Start the application:

   docker-compose up -d

The application will be available at:

• Frontend: http://localhost
• Auth Service: http://localhost:3001
• Appointment Service: http://localhost:3002

1. Install dependencies for all services:

   # Frontend
   cd www
   npm install
   
   # Auth Service
   cd ../api/auth-service
   npm install
   
   # Appointment Service
   cd ../appointment-service
   npm install

2. Set up databases:

   • PostgreSQL for auth and appointment services
   • Redis for caching and sessions

3. Start each service:

   # Frontend
   cd www
   npm run dev
   
   # Auth Service
   cd ../api/auth-service
   npm run start:dev
   
   # Appointment Service
   cd ../appointment-service
   npm run start:dev

Each service includes unit and integration tests:

# Run frontend tests
cd www
npm test

# Run auth service tests
cd api/auth-service
npm test

# Run appointment service tests
cd api/appointment-service
npm test
