MongoDB & NoSQL
Master Document-Based Database Development. Learn Collections, Documents, CRUD Operations, and the Aggregation Pipeline for Scalable Applications.
Flexible Schema Design • High Performance CRUD • Powerful Data Aggregation • Real-World Applications
MongoDB + Node.js + Express Example
const express = require(‘express’);
const mongoose = require(‘mongoose’);
// Create Express app
const app = express();
app.use(express.json());
// Connect to MongoDB
mongoose.connect(‘mongodb://localhost:27017/blog-api’, {
“useNewUrlParser”: true,
“useUnifiedTopology”: true
});
// Define a MongoDB Schema
const postSchema = new mongoose.Schema({
“title”: String,
“content”: String,
“tags”: [String],
“createdAt”: { type: Date, default: Date.now }
});
const Post = mongoose.model(‘Post’, postSchema);
// Define a simple route
app.get(‘/’, async (req, res) => {
const posts = await Post.find().limit(5);
res.json({
“message”: ‘MongoDB API Running!’,
“recentPosts”: posts,
“timestamp”: new Date()
});
});
// Start server
const PORT = process.env.PORT || 3000;
app.listen(PORT, () => {
console.log(`MongoDB API server running on port ${PORT}`);
});
const mongoose = require(‘mongoose’);
// Create Express app
const app = express();
app.use(express.json());
// Connect to MongoDB
mongoose.connect(‘mongodb://localhost:27017/blog-api’, {
“useNewUrlParser”: true,
“useUnifiedTopology”: true
});
// Define a MongoDB Schema
const postSchema = new mongoose.Schema({
“title”: String,

});
const Post = mongoose.model(‘Post’, postSchema);

res.json({

});
});
// Start server
const PORT = process.env.PORT || 3000;
app.listen(PORT, () => {

});
