Node.js is a server-side JavaScript platform using an event-driven, non-blocking I/O model allowing users to build fast and scalable data-intensive applications running in real time. Modern Web Development with Node.js is a comprehensive, hands-on course that provides students with a solid foundation in the latest skills and techniques for mastering and leveraging using Node.js. You will progress from a rudimentary knowledge of JavaScript and server-side development to being able to create, maintain, deploy and test your own Node.js application. You will understand the importance of transitioning to functions that return Promise objects, and the difference between fs, fs/promises and fs-extra. With this course you'll learn how to use the HTTP Server and Client objects, data storage with both SQL and MongoDB databases, real-time applications with Socket.IO, mobile-first theming with Bootstrap, microservice deployment with Docker, authenticating against third-party services using OAuth, and use some well-known tools to beef up security of Express 4.16 applications.

Skills Gained

Working within in an engaging, hands-on learning environment, guided by our expert team, attendees will learn to:

  • Learn server-side JavaScript coding through the most up-to-date course on Node.js
  • Explore the latest JavaScript features, and EcmaScript modules
  • Walk through different stages of developing robust applications using Node.js

Who Can Benefit

This is an introductory level course for experienced software developers seeking to enhance and extend their core web development skillset leveraging NodeJS. Attendees should have practical experience developing basic software applications. This course provides an excellent foundation for continued learning to gain in-demand skills in in-demand skills and technologies such as Angular, React, Redux and more. This course can also be tailored for less experienced or non-developers as needed.
