NodeJS, Express and MongoDB Training Course

NodeJS, Express and MongoDB Training Course
NodeJS, Express and MongoDB Training Course


Node.js, or Node, is a runtime environment for executing JavaScript code outside of a browser. It is ideal for building highly-scalable, data-intensive backend services (APIs) that power your client’s apps (web or mobile apps).

Do you want to build fast and powerful back-end applications with JavaScript? Would you like to become a more complete and in-demand developer? Then Node.js is the hot technology for you to learn right now, and you came to the right place to do it. This course is the perfect all-in-one package that will take you from a complete beginner to an advanced, highly-skilled Node.js developer.

Who should attend?

  • Beginner or advanced web developers who want to dive into backend (server-side) development.
  • Back-end developers familiar with other frameworks like ASPNET, Rails, Django, etc and want to add Node to their toolbox.


  • Any computer and OS will work — Windows, macOS or Linux
  • Absolutely NO understanding of NodeJS or back-end development is required
  • Basic understanding of JavaScript is required
