Node.js & Express

Backend Development with JavaScript

Description

Node.js is a JavaScript runtime that allows you to build fast and scalable server-side applications. Express.js, a minimal and flexible Node.js web application framework, makes it easier to handle HTTP requests, manage routing, and create RESTful APIs. In this course, you will learn the fundamentals of Node.js and Express, starting with setting up your development environment, building simple APIs, and working with databases. You’ll also explore key concepts like middleware, authentication, and error handling. By the end of the course, you will be capable of building and deploying production-ready backend applications using Node.js and Express.js.

Course Content

Introduction to Node.js and Express

Overview of Node.js and Express, and their role in backend development.

Setting Up Node.js and Express

Install Node.js, set up the environment, and create your first Express app.

Understanding npm and Package Management

Learn how to use npm (Node Package Manager) to manage dependencies and libraries.

Routing in Express

Learn how to handle different HTTP methods (GET, POST, PUT, DELETE) and create routes in Express.

Middleware in Express

Understand middleware in Express and how to use it to modify requests and responses.

Handling Requests and Responses

Learn how to capture and process incoming data and send appropriate responses to the client.

Connecting to Databases (MongoDB & MySQL)

Learn how to connect your Express app to databases like MongoDB (NoSQL) and MySQL (SQL) to store data.

Building RESTful APIs with Express

Learn how to create a RESTful API with Express, covering routes, HTTP methods, and CRUD operations.

Authentication and Authorization

Implement user authentication using JWT (JSON Web Tokens) and secure routes for authorized users.

Error Handling and Debugging

Best practices for handling errors and debugging Express applications

Requirements

Basic knowledge of JavaScript (preferably after completing the JavaScript and React courses).
A computer with internet access.
Code editor: Visual Studio Code (recommended).
Node.js and npm installed on your system (instructions provided).
Familiarity with HTTP and REST concepts is helpful but not required.
