Lesson 3: MongoDB Document Database & Mongoose ODM

1. NoSQL Documents with MongoDB & Mongoose

MongoDB is a document-oriented database that stores records as flexible, JSON-like BSON documents. Mongoose provides a schema-based solution to model application data.

Schema Definition: Enforces required types, defaults, and validations.

Model Instance: Interacts with the database collection for CRUD operations (User.find(), User.create()).

⊞Code Example

import mongoose from 'mongoose';

const StudentSchema = new mongoose.Schema({

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

email: { type: String, required: true, unique: true },

enrolledCourse: { type: String, default: 'Full Stack Web Dev' },

completedLessons: { type: [Number], default: [] },

createdAt: { type: Date, default: Date.now }

});

export const Student = mongoose.model('Student', StudentSchema);
