ClinIQ uses **Google's Gemini 2.0 Flash AI model** to deliver structured, multi-lingual preliminary analyses (urgency classification, potential conditions, dietary advice, and medication safety warnings). +2. **Doctor Discovery & Consultation Scheduling**: Simplifies finding verified medical specialists filtered by area of expertise, experience, consultation fees, and real-time availability. +3. **Role-Based Medical Data Management**: Provides distinct, secure portals for **Patients** (medical history, active prescriptions, appointments) and **Doctors** (schedule management, patient consultation history) powered by **Supabase (PostgreSQL) with Row Level Security (RLS)**. +4. **Medical Knowledge Accessibility**: Integrates educational tools such as a Drug Database, Medical Dictionary, First Aid Guides, Medical Research Papers, and PIN code-based Hospital Locator. + +--- + +## πŸ“ High-Level Architecture Diagram + +ClinIQ follows a modern **JAMstack (JavaScript, API, Markup)** architecture with a decoupled React single-page frontend, a managed Supabase backend, and external AI service integrations. + +``` +β”Œβ”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β” +β”‚ CLIENT LAYER β”‚ +β”‚ React 18 + TypeScript + Tailwind CSS + Framer Motion (Vite-bundled SPA) β”‚ +β”‚ - React Router v6 (Route-based Code Splitting) β”‚ +β”‚ - Context API (AuthContext, ThemeContext) β”‚ +β”‚ - i18next (Multi-language Support: EN, ES, HI) β”‚ +β””β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”¬β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”˜ + β”‚ + β”‚ HTTP / HTTPS + β”Œβ”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”Όβ”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”¬β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β” + β–Ό β–Ό β–Ό β–Ό + β”Œβ”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β” β”Œβ”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β” β”Œβ”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β” β”Œβ”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β” + β”‚ Supabase β”‚ β”‚ Google AI β”‚ β”‚ Browser Localβ”‚ β”‚ Vercel CDN β”‚ + β”‚ Backend β”‚ β”‚ (Gemini API) β”‚ β”‚ Storage β”‚ β”‚ Hosting β”‚ + β””β”€β”€β”€β”€β”€β”€β”¬β”€β”€β”€β”€β”€β”€β”€β”˜ β””β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”˜ β””β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”˜ β””β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”˜ + β”‚ + β”œβ”€β”€β”€ Auth (JWT + Row Level Security) + β”œβ”€β”€β”€ PostgreSQL Database (`profiles`, `doctor_profiles`) + └─── RESTful API Auto-generated Endpoints +``` + +--- + +## πŸ› οΈ Technology Stack Breakdown + +| Layer | Technology | Purpose & Usage | +| :--- | :--- | :--- | +| **Frontend Framework** | **React 18** | Functional UI components, hooks, and Virtual DOM rendering. | +| **Type Safety** | **TypeScript 5** | Strict interfaces, type definitions for medical data and API payloads. | +| **Build Tool & Bundler**| **Vite 5** | Fast HMR (Hot Module Replacement), optimized ESbuild production bundles. | +| **Styling & UI** | **Tailwind CSS + Framer Motion** | Utility-first styling, dark/light theme tokens, and smooth micro-animations. | +| **State Management** | **React Context API** | Global auth session state (`AuthContext`) and theme state (`ThemeContext`). | +| **Routing** | **React Router v6** | Client-side routing, protected route guards (`ProtectedRoute.tsx`), dynamic lazy loading. | +| **Internationalization**| **i18next + react-i18next** | Dynamic translation for English (`en`), Spanish (`es`), and Hindi (`hi`). | +| **Backend & Database** | **Supabase (PostgreSQL)** | Managed PostgreSQL database, JWT authentication, auto-generated REST API, and RLS. | +| **AI Integration** | **Google Gemini API (`gemini-2.0-flash`)** | Natural language symptom interpretation, structured JSON extraction, and severity scoring. | +| **PDF & Export** | **jsPDF + jsPDF-AutoTable** | Dynamic generation of downloadable PDF medical reports and summaries. | +| **Testing** | **Vitest + Testing Library** | Unit and integration testing for service layers (`PDFExportService`, `LocalStorageService`). | + +--- + +## πŸ“‚ Directory & Module Structure + +``` +ClinIQ/ +β”œβ”€β”€ .github/ #

Unrecognized levels trigger explicit fallback errors rather than silently downgrading severity. +- **Graceful Fallback**: If `VITE_GEMINI_API_KEY` is not present, the app gracefully falls back to mock symptom results defined in `mockData.ts`. + +--- + +### 3.
