Running Axon Server in a Virtual Machine

In this series, we’ve been looking at running Axon Server locally, in Docker, and Kubernetes. What happens if we use a VM as a platform? Naturally, we need to do more work to get everything set up correctly, because instead of sharing a part of the Operating System, we now have to consider everything from the machine and upwards.

Testing Quarkus Web Applications: Reactive Messaging, Kafka, and Testcontainers

Quarkus is a full-stack, Kubernetes-native Java framework that supports many coding styles, including reactive programming. Writing clean unit/component/integration tests for Quarkus applications when a reactive approach is used is vitally important. Here we demonstrate testing reactive code, reactive messaging, and full integration testing.

Pathpida Brings Types to Next.js and Nuxt.js Dynamic Routing with Zero Configuration

Pathpida is a library for TypeScript projects to collect dynamic routes in one place. It is a tedious task to do manually. This helps check the existence of routes in large web apps. Pathpida is optimized for Next.js (React) and Nuxt.js (Vue). Pathpida can be added to existing Next.js and Nuxt.js projects without configuration.
