Nodejs/MongoDB Training

A Node.js course focuses on teaching you how to use Node.js, a JavaScript runtime environment, to build scalable and high-performance web applications. Whether you're a beginner or an experienced developer, this course will cover both the basics and advanced features of Node.js, preparing you for a wide variety of real-world applications such as APIs, web servers, and more.

MongoDB is an essential tool for modern web development, especially when building applications that need flexibility, scalability, and performance. By mastering MongoDB, you can handle complex data structures, build high-performing databases, and scale applications to meet the demands of modern businesses.

Introduction to Node.js

What is Node.js?: Understanding Node.js as a runtime built on Chrome’s V8 JavaScript engine that allows you to run JavaScript outside the browser, enabling full-stack JavaScript development.
Setting up Node.js: Installing Node.js and npm (Node Package Manager) and creating a basic Node.js application.
Core Concepts: Learn about the event-driven, non-blocking I/O model that makes Node.js fast and scalable for handling asynchronous operations.
Node.js Modules: Working with built-in Node.js modules such as http, fs, path, and os for basic file operations, HTTP requests, and more.

Asynchronous Programming in Node.js

Callbacks: Understanding the use of callbacks in Node.js for handling asynchronous operations.
Functions: defining, calling, and passing parameters.Promises: How to manage asynchronous operations using Promises, which offer a more elegant solution to callbacks.
Async/Await: Using async/await syntax to write asynchronous code that is easier to read and maintain.
Event Loop: Understanding how Node.js handles asynchronous tasks using the event loop.

Building a Web Server with Node.js

Express.js Framework: Learn to use Express.js, a minimal and flexible web framework for building web applications and APIs in Node.js.
Routing: Set up route handlers for GET, POST, PUT, and DELETE requests in your application.
Middleware: Use middleware functions in Express to handle requests, manage sessions, log requests, and handle errors.
Serving Static Files: Learn to serve static assets such as images, CSS, and JavaScript files to the client.

Introduction to MongoDB

What is MongoDB?: Understanding MongoDB as a NoSQL database and how it differs from traditional relational databases.
Setting up MongoDB: Installing and setting up MongoDB locally or using cloud solutions like MongoDB Atlas for easy database management.
Basic MongoDB Operations: Learn how to perform CRUD (Create, Read, Update, Delete) operations using MongoDB Shell and MongoDB Compass.
Collections and Documents: Understand how MongoDB stores data in collections and documents (JSON-like format).

Connecting Node.js with MongoDB

MongoDB Node.js Driver: Learn how to use the official MongoDB Node.js Driver to connect a Node.js application with MongoDB.
Mongoose: Learn how to use Mongoose, an Object Data Modeling (ODM) library for MongoDB and Node.js. Mongoose simplifies interacting with MongoDB and allows you to define schemas for your data models.
CRUD Operations with MongoDB: Perform CRUD operations within your Node.js app, using Mongoose to interact with MongoDB.

Building RESTful APIs with Node.js and MongoDB

API Design: Learn the fundamentals of designing RESTful APIs, including HTTP methods (GET, POST, PUT, DELETE) and best practices for building scalable and maintainable APIs.
Routing for APIs: Set up routes and endpoints in your Express.js application to handle API requests.
Handling Request Data: Learn to process incoming data from the client (query parameters, request bodies) and return the appropriate responses (JSON, status codes).
Authentication: Implement authentication mechanisms using JWT (JSON Web Tokens) for secure API endpoints, along with middleware to protect routes.
Error Handling: Learn to handle errors in your APIs gracefully, sending appropriate error responses to clients.
