This demo is made of 3 parts

• map-render - renders png tiles of maps
• map-server - serves the maps using a simple HTTP server
• frontend - a js + npm vert.x frontend

mvn clean install

java -jar map-render/target/map-render-1.0.0-SNAPSHOT-fat.jar --cluster

repeat the above as many times as you like...

java -jar map-server/target/map-server-1.0.0-SNAPSHOT-fat.jar --cluster

For the frontend we need a running redis server in order to store the recommendation, for this we can quickly launch an ephemeral redis server using docker:

sudo docker run -p 6379:6379 redis

And the just use npm

cd frontend
npm start

Then open a browser to http://localhost:8080.
