SETUP

$ mkdir client server $ npm i express mongoose dotenv $ npm i --save-dev nodemon concurrently

FRONT END

cd client npx create-react-app rm -rf .git (To remove git repo in client folder)

BACKEND

"change main in package.json to server.js"

In server.js

require("dotenv").config() const express = require('express'); const app = express() const connectDB = require("./config/db") const productRoutes = require("./routes/productRoutes")

connectDB()

const PORT = process.env.PORT || 5000

app.use(express.json()) // ! Creating routes

app.use("/api/products", productRoutes);

app.listen(PORT, () => { console.log(Server is running on ${PORT});

})

CLI

$ cd server $ mkdir config controller data models routes

Create db.js in config folder

require("dotenv").config() const mongoose = require('mongoose'); const connectDB = async () => { try { await mongoose.connect(process.env.MONGO_URI, { useNewUrlParser: true, useUnifiedTopology: true }); console.log("MongoDB connected successfully") } catch (error) { console.log("MongoDB connection failed") console.log(error) process.exit(1)

} }

module.exports = connectDB

Create Product.js in models folder to define schema for MongoDB

const mongoose = require('mongoose'); const productSchema = new mongoose.Schema({ name: { type: String, required: true }, description: { type: String, required: true }, price: { type: Number, required: true

},
countInStock: {
    type: Number,
    required: true

},
countInStock: {
    type: String,
    required: true

}

})

const Product = mongoose.model("product", productSchema)

module.exports = Product

Create a products.js file under data and export an array of objects >>> Create seederScript.js in server directory (to import data to MongoDB)

require('dotenv').config(); const connectDB = require('./config/db'); const productsData = require('./data/products'); const Products = require('./models/Product');

connectDB();

importData()

Create productControllers.js in controller file

const Product = require('../models/Product'); const getAllProducts = async (req, res) => { try { const products = await Product.find();

    // ! Makes a request to products in database
    res.json(products);
} catch (error) {
    console.log(error);
    res.status(500).json({ message: 'Server error occured' });
}

}; const getProductbyId = async (req, res) => { try { const product = await Product.findById(req.params.id); if (!product) { res.status(404).json({ message: 'Product not found' }); }

    // ! Makes a request to products in database
    res.json(product);
} catch (error) {
    console.log(error);
    res.status(500).json({ message: 'Server error occured' });
}

};

module.exports = { getAllProducts, getProductbyId, };

Create productRoutes.js in routes file

const express = require('express'); const router = express.Router()

const { getAllProducts, getProductById} = require("../controller/productControllers")

// ! desc : GETS all products from database // ! route : GET /api/products // ! access: public

router.get("/", getAllProducts)

// ! desc : GETS specific product from database // ! route : GET /api/products/:id // ! access: public router.get("/:id", getProductById)

module.exports = router
