The portlet show current online users count. It is refreshed every 5 seconds and updates automatically.

Used this excellent sample as the boilerplate:

• https://gpicavet.github.io/jekyll/update/2016/09/17/getting-started-exo-reactjs.html

Standalone mode

• install dependencies

npm install

• build

npm run release

• build in watch mode (rebuild on *.js(x) change)

npm run watch

• start express server

npm start

And go to http://localhost:3000/

Portlet mode

• build (portlet and npm)

mvn clean install

• build with webpack optimizations

mvn clean install -Pproduction

• deployment
• either deploy the target/react-portlet.zip as EXO ADDON :

${EXO_APP_DIR}/addon install --catalog=file://catalog.json users-count-portlet:1.0.0 --force --batch-mode

• or copy the target/react-portlet.war into EXO webapps dir

• Note on docker : Deployment in a docker container won't work, due to minifier problem :(. i have to look into it But it seems to work with a standard Exoplatform bundle (even in normal mode and webpack optimizations).
