MongoDB with Mongoose
Connect Express to MongoDB using Mongoose ODM for data modeling
javascript
const mongoose = require('mongoose');
// Connect to MongoDB
mongoose.connect('mongodb://localhost:27017/mydb', {
useNewUrlParser: true,
useUnifiedTopology: true
});
// Define schema
const userSchema = new mongoose.Schema({
name: { type: String, required: true },
email: { type: String, required: true, unique: true },
age: Number,
createdAt: { type: Date, default: Date.now }
});
const User = mongoose.model('User', userSchema);🟢 Essential for MongoDB - Mongoose simplifies database operations
💡 Define schemas for data validation and structure
⚡ Use connection pooling for better performance
📌 Handle connection errors and implement retry logic
⚠️ Never expose database credentials in code
