Updating Microservices with Netty 5, Kafka 3, and React: Whirlpool Revisited

John Boardman Articles, Development Technologies & Tools, Java, JavaScript, Microservices, React Leave a Comment

Back in 2015 and 2016, I wrote two blogs that went step by step to develop a microservice/Netty architecture with fully working code called Whirlpool.

A lot has changed in the years since, so recently I decided to come back to the project, update it with the latest versions of Kafka and Netty, and add a React UI to it (rather than the vanilla JavaScript version it used before). In addition, I also added Windows Subsystem for Linux (WSL) scripts in addition to the Mac and Linux scripts that were there before and made all of the scripts more robust.

This blog will be about the work that went into all of those updates, plus a look at the new React UI. This provides an excellent view into what it takes to update an outdated microservices application implemented with Kafka (version .9 –>3.0) and Netty (4.1.3->5.0.0-alpha2), bringing all versions up to date and adding a React UI. By the end you’ll be familiar with the latest versions of these frameworks, know some “gotchas” to avoid, as well as understand how to integrate WebSockets into React.

A Keyhole Consultant was brought in to directly work with the client’s full-stack development team. The goal of the project was to help the client implement new features for their application. This resulted in the implementation of a new GraphQL API and architecture for multiple interdependent systems. Keyhole Software was responsible for coaching the client’s development team in React best-practices, and working with them to refactor the code to align with those best practices.
