Duration 3 days – 21 hrs
Overview
This hands-on training course is designed for engineers and developers new to Node.js. It introduces the fundamentals of Node.js as a backend runtime environment for building modern, scalable web applications. Participants will learn how Node.js works, how to build and run a web server, manage routes and APIs, handle data, and structure a basic backend project using Express.js. By the end of the course, learners will have a working understanding of how to develop backend services using JavaScript and Node.js.
Objectives
- Understand the architecture and core concepts of Node.js
- Set up a development environment for building Node.js applications
- Use Node.js modules and npm packages effectively
- Build RESTful APIs using Express.js
