In the first blog post of this series, we learned how to send serialized data from a React frontend to a NestJS backend with Axios and Cap’n Proto. This blog post will focus on propagating the received data from service to service in a Kubernetes environment using NestJS clients coupled with a Nats JetStream message bus.
I will explain how to install a properly configured Nats JetStream message bus in a Kubernetes cluster using Helm and Ansible and how to connect the NestJS clients to JetStream afterward. To avoid complexity, we’ll use Minikube, an easy-to-install Kubernetes cluster with just one node. We will also partially use the code and generated data from the last blog article. Both code and data are available on GitHub.Weiterlesen
