Mongoose Mongodb

pluginagentmarketplace/custom-plugin-nodejs

If you're building Node.js apps that need a database, this gets you productive with MongoDB fast. You'll learn schemas with built-in validation, CRUD operations, relationships with population, and query operators for filtering data. The progression makes sense: start with basic connects and models, move into indexes and middleware hooks, then tackle aggregation pipelines and transactions. Mongoose adds structure to MongoDB's flexibility, which is great until you need to fight the ODM layer, but for most CRUD apps it's the standard choice. The examples cover real patterns like password hashing in pre-save hooks and virtual properties, not just toy demos.

Mongoose & MongoDB Skill

Master MongoDB database integration in Node.js with Mongoose, the elegant object modeling library.

Quick Start

Connect and CRUD in 4 steps:

Install - npm install mongoose
Connect - mongoose.connect(uri)
Define Schema - Create data models
CRUD - Create, Read, Update, Delete

Core Concepts

Connection Setup

const mongoose = require('mongoose');

mongoose.connect(process.env.MONGODB_URI, {
  useNewUrlParser: true,
  useUnifiedTopology: true
});

mongoose.connection.on('connected', () => {
  console.log('MongoDB connected');
});

Schema & Model

const userSchema = new mongoose.Schema({
  name: {
    type: String,
    required: [true, 'Name is required'],
    trim: true,
    minlength: 3,
    maxlength: 50
  },
  email: {
    type: String,
    required: true,
    unique: true,
    lowercase: true
  },
  age: {
    type: Number,
    min: 18,
    max: 120
  },
  role: {
    type: String,
    enum: ['user', 'admin'],
    default: 'user'
  }
}, {
  timestamps: true  // createdAt, updatedAt
});

const User = mongoose.model('User', userSchema);
