NodeJS (advanced) training course (code: NODEJS)

Best Practices and Advanced techniques for developing Robust End-to-End Backend Applications With NodeJS



This is an intensive hands-on training course aimed at seasoned Node developers

The purpose of the course is to instil a deeper understanding of the language and best practices so as to allow delegates to feel confident that they are developing applications efficiently and optimally, using appropriate language, techniques, tools and test techniques.

Delegates will be introduced to theory and spend most of the time practicing the theory using specially developerd hands-on Labs.


Seasoned Node developers looking to gain a deeper understanding of the language and best practice
