Oracle Java Engineer Igor De Souza Shows How To Create a Quarkus Templating Engine Qute Demo with a Raspberry PI

This article is to show how I created a Quarkus Qute demo with a Raspberry PI.

Quarkus is a full-stack, Kubernetes-native Java framework made for Java virtual machines (JVMs) and native compilation, optimizing Java specifically for containers and enabling it to become an effective platform for serverless, cloud, and Kubernetes environments.

Qute is a templating engine designed specifically to meet the Quarkus needs. The usage of reflection is minimized to reduce the size of native images. The API combines both the imperative and the non-blocking reactive style of coding. The engine is based on RESTEasy/JAX-RS. As such, Qute web applications are implemented by defining resource types with methods answering to specific HTTP verbs and accept headers. The only difference being, that HTML pages are returned instead of JSON as in your typical REST-ful data API. The individual pages are created by processing template files.

If you’ve worked with other templating engines before, like me, this will look very familiar to you.

Note: Qute is an experimental feature.

Idea

A simple Quarkus Qute example that shows a 7 segments display and control in real-time a real one with a Raspberry Pi 3 B.

When I was googling about a 7 segment display this site appeared in my result and I came up with the idea.
