🧠 Step-by-Step Development Process

🔹 Step 1: Project Setup and Dependencies

• Initialized Node.js project with npm init
• Installed dependencies:

  npm install express mongoose dotenv cors bcryptjs jsonwebtoken

• Folder Structure:

  backend/
  ├── config/
  ├── controllers/
  ├── middleware/
  ├── models/
  ├── routes/
  ├── .env
  ├── index.js
  

---

🔹 Step 2: Environment Configuration

• .env File:

  PORT=5000
  MONGODB_URI=paste your uri here
  JWT_SECRET=mysecretkey
  

---

🔹 Step 3: MongoDB Connection

• Connected to MongoDB using Mongoose inside config/db.js
• Imported the connection in index.js
• Handled success and failure logs

---

🔹 Step 4: User Authentication System

• Model: User (name, email, password)
• Routes:
  • POST /api/auth/register – Register a new user
  • POST /api/auth/login – Login and get JWT token
• Password hashed with bcryptjs, token generated with jsonwebtoken
• Middleware: authMiddleware.js to protect routes

---

🔹 Step 5: Service Listing APIs

• Model: Service (title, description, price ,category)
• Routes:
  • POST /api/services – Add a service (Protected)
  • GET /api/services – Fetch all services

---

🔹 Step 6: Booking System Implementation

• Model: Booking
  • user → references User
  • service → references Service
  • status (default: Confirmed)
• Routes:
  • POST /api/bookings – Book a service (Protected)
  • GET /api/bookings – Get all bookings for the logged-in user

---

🔹 Step 7: API Testing (via RapidAPI Client)

📍 1. Register User

• Endpoint: POST /api/auth/register
• Body:

  {
    "name": "Ravi",
    "email": "ravi@google.com",
    "password": "1234"
  }

📍 2. Login User

• Endpoint: POST /api/auth/login
• Body:

  {
    "email": "ravi@google.com",
    "password": "1234"
  }

• ✅ Returns JWT token

📍 3. Add Service

• Endpoint: POST /api/services
• Headers:

  {
    "Authorization": "Bearer <your_jwt_token>"
  }

• Body:

  {
    "title": "AC Repair",
    "description": "Air conditioner maintenance and repair",
    "Price" : 1000
    "category": "Repair"
  }

📍 4. Get All Services

• Endpoint: GET /api/services

📍 5. Book a Service

• Endpoint: POST /api/bookings
• Headers:

  {
    "Authorization": "Bearer <your_jwt_token>"
  }

• Body:

  {
    "service": "<service_id>"
  }

📍 6. View My Bookings

• Endpoint: GET /api/bookings
• Headers:

  {
    "Authorization": "Bearer <your_jwt_token>"
  }

---

🔹 Step 8: Finalizing the Server

• Start Server:

  cd backend (navigate to backend folder)
  node index.js (run index.js file)
  

• Server:

  MongoDB Connected 👍👍  
  Server is running on http://localhost:5000
