MediHaven Hospital System Architecture

The MediHaven Hospital System is a robust, scalable web application built with React and TypeScript, designed to streamline hospital operations for various stakeholders including Patients, Doctors, Nurses, Lab Technicians, and Administrators. This documentation provides an in-depth overview of the system’s architecture, its components, and their interactions.

πŸ’‘ What is a React-based Application?
A React-based application uses the React JavaScript library to build interactive user interfaces with reusable components, improving development speed and maintainability.


System Overview

The MediHaven Hospital System is a frontend-heavy application that leverages modern web technologies to deliver a seamless user experience. It integrates with a Content Delivery Network (CDN) using Vite, employs React Router for navigation, and uses Axios for API interactions. The system is divided into several layers and subsystems, each serving a specific purpose within the hospital ecosystem.

Key Stakeholders

  • Patient: Accesses personal health data and appointments.
  • Doctor: Manages patient records and treatment plans.
  • Nurse: Handles patient care and updates.
  • Lab Technician: Processes lab tests and imaging.
  • Admin: Oversees system configuration and user management.

πŸ’‘ Why Use a CDN with Vite?
A CDN (Content Delivery Network) paired with Vite speeds up asset delivery by caching static files globally, reducing latency for users accessing the MediHaven system from different locations.


Architecture Breakdown

The system is organized into a modular structure with distinct layers: Frontend Application, Authentication System, Lab System, Admin System, and Data Layer. Below is a detailed breakdown of each component.

1. Frontend Application

The core of the system is the Frontend Application, built with React and TypeScript. It serves as the entry point for all users and is responsible for rendering the UI and managing client-side logic.

Core Components

  • Router (React Router): Handles navigation and route protection.
  • Auth Guard (React Context): Ensures route security using authentication checks.
  • Dashboard Context (React Context): Manages shared state across dashboards.
  • Web Application (React + TypeScript): The main application container.

πŸ’‘ What is React Router?
React Router is a library that enables dynamic routing in React applications, allowing MediHaven to load different modules (e.g., Doctor or Patient) based on the URL without a full page refresh.

Feature Modules

These modules provide role-specific functionality:

  • Admin Module: Administrative tools and dashboards.
  • Doctor Module: Patient management and diagnostics.
  • Nurse Module: Care coordination and updates.
  • Lab Module: Test processing and imaging.
  • Patient Module: Personal health portal.

Shared Components

Reusable UI elements used across modules:

  • UI Components (Shadcn/ui): Custom UI library.
  • Layout Components (React): Structural components.
  • Form Components (React): Input handling.
  • Chart Components (React): Data visualization.

πŸ’‘ What is Shadcn/ui?
Shadcn/ui is a collection of customizable, reusable UI components that MediHaven uses to ensure a consistent and modern design across all modules.


2. Authentication System

The Authentication System ensures secure access using JWT (JSON Web Tokens) and RBAC (Role-Based Access Control).

Components

  • Auth Service (JWT): Manages user authentication.
  • Role Manager (RBAC): Assigns and validates user roles.
  • Session Handler (Browser Storage): Persists session data.

πŸ’‘ What is an IAM User Equivalent in MediHaven?
Similar to an IAM user in AWS, MediHaven’s Role Manager (RBAC) assigns specific permissions to users (e.g., Doctor, Admin), ensuring secure access to resources without exposing critical system controls.


3. Lab System

The Lab System handles laboratory workflows, integrating AI/ML for result analysis.

Components

  • Lab Test Processor (React): Processes lab test data.
  • Results Analyzer (AI/ML): Analyzes test results.
  • Imaging Viewer (React): Displays imaging results.

πŸ’‘ Why Use AI/ML in the Lab System?
The Results Analyzer leverages AI/ML to provide faster and more accurate analysis of lab data, enhancing diagnostic capabilities for Lab Technicians and Doctors.


4. Admin System

The Admin System provides tools for system management and analytics.

Components

  • System Configuration (React): Manages system settings.
  • User Role Management (React): Controls user permissions.
  • Analytics Engine (React): Generates system insights.

πŸ’‘ What is User Role Management?
User Role Management in MediHaven allows Admins to define permissions (e.g., read-only for Nurses, full access for Doctors), ensuring compliance with healthcare security standards.


5. Data Layer

The Data Layer manages state and API interactions.

Components

  • Data Context (React Context): Centralized state management.
  • API Client (Axios): Handles HTTP requests.

πŸ’‘ Why Use Axios in the Data Layer?
Axios simplifies HTTP requests with features like automatic JSON parsing and error handling, making it ideal for MediHaven’s API interactions with backend services.


Full System Flow

The following flowchart illustrates how users interact with the MediHaven Hospital System and how data flows through its components.

πŸ’‘ How Does the Full System Flow Enhance Security?
By integrating Auth Guard and Role Manager, MediHaven ensures that only authorized users access specific modules, protecting sensitive patient data from unauthorized access.

πŸ’‘ What is TypeScript’s Role in MediHaven?
TypeScript adds static typing to JavaScript, reducing runtime errors and improving code quality in MediHaven’s complex healthcare application.


Conclusion

The MediHaven Hospital System is a meticulously designed application that balances modularity, security, and performance. By leveraging React’s component-based architecture, TypeScript’s type safety, and a robust authentication system, it provides a reliable platform for healthcare professionals and patients alike. This documentation serves as a blueprint for developers and stakeholders to understand and extend the system.
