Lightbend Lagom for Java - Hello World

This course is a gentle introduction to Lagom through the implementation of a simple Hello World application.

About This Course

The Lagom microservice framework provides developers with tools that allow them to rapidly build systems of Reactive microservices, using advanced techniques such as CQRS, Event Sourcing, Reactive Streams, Message Driven Architectures and more. But before you start using the advanced techniques of Lagom, you need a place to start.

This Lagom course takes students through a simple Lagom Hello World. You will learn how to setup your Maven project to support Lagom. You will see how to define the interface for your microservice. You will implement that microservice, including writing tests to verify the functionality. Finally you will see how Lagom microservices can communicate with each other by implementing a simple client application to consume your microservice.
