Build Microservices with Node.js, Dublin

This course is for you if

• you are considering microservices for your organization,
• you want to understand microservices better,
• you want to migrate to microservices,
• you want hands-on experience in building microservices with Node.js.

Prerequisites

• Prior Javascript and Node.js experience is nice to have. You will understand the coding part a lot easier, as we won't go into the basics of Node.js

• No prior experience with microservices is required - we will cover everything you need to get started.

The exact location of the venue in Dublin will be announced later.
