The purpose of this lab series is to gradually build a complete GraalVM Polyglot application using various languages:
JavaJavascriptPythonR
Functionally, the application makes it possible to visualize the covid-19 hospitalizations trends in a French department. This application relies on data provided by the French Pucblic Health Agency Santé Publique France.
The application consists of a JAX-RS Controller with a set of REST Helidon endpoints that enables users to visualize a Covid-19 evolution in France in a Polyglot way.
