Lab Recipes: MONGOOSE API Programming

Node.js and MongoDB using Mongoose

Let's imagine you're a chef, ready to create a scrumptious meal, but in this case, the meal is a simple yet effective Mongoose API: Mogoose is the Node.js API package to connect to a MONGO database from JavaScript Code.

Step 1: Setting Up the Kitchen (Visual Studio Code and Project Setup)

Install Visual Studio Code: It's like choosing the right kitchen for our cooking. If you haven't already, download and install it from

Visual Studio Code website⁠

Create a New Folder: This will be your project folder. Right-click in your desired directory and select 'New Folder'.

Open the Folder in VS Code: Open VS Code, go to 'File' > 'Open Folder', and select the folder you just created.

Initialize Your Project: Open the terminal in VS Code (Terminal > New Terminal) and type npm init. This is like laying out your ingredients. Follow the prompts to create your package.json file.

Step 2: Gathering Ingredients (Installing Dependencies)

Install Node.js: If you haven’t already, install Node.js from

Node.js website⁠

Install Dependencies: In your terminal, run:

bashCopy code

npm install express mongoose body-parser

These are the ingredients for our API: Express for the server, Mongoose for MongoDB interactions, and Body-Parser for parsing incoming request bodies.

Step 3: Preparing the Recipe (Writing the Code)

Create a File for the Server: In your project folder, create a file named server.js.

Write the Server Code: Here’s a simple server setup:

const express = require('express');

const mongoose = require('mongoose');

const bodyParser = require('body-parser');

const app = express();

app.use(bodyParser.json());

mongoose.connect('mongodb://localhost:27017/studentAttendance', {

useNewUrlParser: true,

useUnifiedTopology: true

});

const db = mongoose.connection;

db.on('error', console.error.bind(console, 'connection error:'));

db.once('open', function() {

console.log("Connected successfully to MongoDB");

});

// Define the Student schema
