🏗 System Architecture

User (Browser)
      ↓
React Frontend
      ↓
REST API (Spring Boot / Node.js)
      ↓
Database (MySQL / MongoDB)

Flow Explanation

1. User performs action in UI.
2. Frontend sends HTTP request via Axios.
3. Backend processes request.
4. Database stores/retrieves data.
5. Response returned to frontend.
6. UI updates dynamically.

⚙ Installation & Setup Guide

1️⃣ Clone Repository

git clone https://github.com/jayesh3103/LendIQ.git
cd LendIQ

---

2️⃣ Backend Setup

Navigate to backend:

cd backend

For Spring Boot:

mvn clean install
mvn spring-boot:run

For Node.js:

npm install
npm start

Backend runs on:

http://localhost:8080

---

3️⃣ Frontend Setup

Navigate to frontend:

cd frontend
npm install
npm start

Frontend runs on:

http://localhost:3000

---

🔑 Environment Variables Setup

Create a .env file inside frontend:

REACT_APP_API_URL=http://localhost:8080
REACT_APP_SECRET_KEY=your_secret_key_here

For backend (Spring Boot example):

Use environment variables instead of hardcoding:

spring.datasource.password=${DB_PASSWORD}

Never push .env or application.properties with real credentials.
