4. Step-by-Step Guides, Tutorials, and Examples

Setting up a Basic Car Auction API with Node.js & Express.js:

1. Project Setup:

Create a new project directory:

mkdir car-auction-api
cd car-auction-api

Initialize npm:

npm init -y

Install dependencies:

npm install express mongoose body-parser cors

2. Define Models (using Mongoose):

Create models/Vehicle.js:

const mongoose = require('mongoose');

const vehicleSchema = new mongoose.Schema({
  make: String,
  model: String,
  year: Number,
  mileage: Number,
  description: String,
  imageUrl: String,
  startingPrice: Number,
  currentBid: {
    type: Number,
    default: 0,
  },
  highestBidder: String,
  auctionEndDate: Date,
  status: {
    type: String,
    enum: ['open', 'closed'],
    default: 'open',
  },
});

module.exports = mongoose.model('Vehicle', vehicleSchema);

3. Configure MongoDB Connection:

Create config/db.js:

const mongoose = require('mongoose');

const connectDB = async () =&gt; {
  try {
    await mongoose.connect(process.env.MONGO_URI, {
      useNewUrlParser: true,
      useUnifiedTopology: true,
    });
    console.log('MongoDB Connected');
  } catch (error) {
    console.error(error.message);
    process.exit(1);
  }
};

module.exports = connectDB;

4. Create Routes (using Express.js):

Create routes/vehicles.js:

const express = require('express');
const router = express.Router();
const Vehicle = require('../models/Vehicle');

// Get all vehicles
router.get('/', async (req, res) =&gt; {
  try {
    const vehicles = await Vehicle.find();
    res.json(vehicles);
  } catch (error) {
    console.error(error.message);
    res.status(500).send('Server error');
  }
});

// Get a single vehicle by ID
router.get('/:id', async (req, res) =&gt; {
  try {
    const vehicle = await Vehicle.findById(req.params.id);
    if (!vehicle) {
      return res.status(404).send('Vehicle not found');
    }
    res.json(vehicle);
  } catch (error) {
    console.error(error.message);
    res.status(500).send('Server error');
  }
});

// Create a new vehicle
router.post('/', async (req, res) =&gt; {
  try {
    const newVehicle = new Vehicle(req.body);
    await newVehicle.save();
    res.json(newVehicle);
  } catch (error) {
    console.error(error.message);
    res.status(500).send('Server error');
  }
});

// Update a vehicle
router.put('/:id', async (req, res) =&gt; {
  try {
    const updatedVehicle = await Vehicle.findByIdAndUpdate(
      req.params.id,
      req.body,
      { new: true }
    );
    if (!updatedVehicle) {
      return res.status(404).send('Vehicle not found');
    }
    res.json(updatedVehicle);
  } catch (error) {
    console.error(error.message);
    res.status(500).send('Server error');
  }
});

// Delete a vehicle
router.delete('/:id', async (req, res) =&gt; {
  try {
    const deletedVehicle = await Vehicle.findByIdAndRemove(req.params.id);
    if (!deletedVehicle) {
      return res.status(404).send('Vehicle not found');
    }
    res.json({ message: 'Vehicle deleted successfully' });
  } catch (error) {
    console.error(error.message);
    res.status(500).send('Server error');
  }
});

module.exports = router;

5. Create Server File (using Express.js):

Create server.js:

const express = require('express');
const connectDB = require('./config/db');
const bodyParser = require('body-parser');
const cors = require('cors');
const vehicleRoutes = require('./routes/vehicles');

const app = express();
const port = process.env.PORT || 5000;

// Connect to MongoDB
connectDB();

// Middleware
app.use(bodyParser.json());
app.use(cors());

// Routes
app.use('/api/vehicles', vehicleRoutes);

// Start server
app.listen(port, () =&gt; {
  console.log(`Server started on port ${port}`);
});

6. Start the Server:

Run the server:

node server.js

Example Vehicle Data:

{
  "make": "Toyota",
  "model": "Camry",
  "year": 2018,
  "mileage": 50000,
  "description": "Excellent condition, low mileage, clean title.",
  "imageUrl": "https://example.com/car-image.jpg",
  "startingPrice": 15000,
  "auctionEndDate": "2024-03-15T23:59:59.999Z",
  "status": "open"
}
