Node.js Training Course

Who should attend

Our Node.js training course is aimed at developers who want to get the most out of Node.js in order to develop, test and deploy JavaScript apps, simple web services and APIs on the popular runtime.

Prerequisites

Familiarity with the basic concepts of JavaScript is required - an advanced knowledge of JavaScript will not be assumed.

If you are interested in custom / on-site Node.js training for your development team, please do get in touch. We can take into account your project requirements, existing technical skills and timeframes to suit your needs, and tailor the most relevant and focussed course for you – such as building exercises around your working practices, preferred IDE, server architecture and target audience.
