Use node version 6.0.0 through nvm (https://github.com/creationix/nvm).

cd %examplename%
nvm use 6.0.0
npm i
npm run build
npm start

npm run build will create the minified js file for production use

npm start will start up the debug server at http://localhost:3000/

npm run package will generate a production version of the application.

Applications that need access to a local GeoServer will need to run (in addition to npm start):

npm run start:proxy this will start up the application at http://localhost:4000/ and will have a proxy to a local geoserver on port 8080 (proxy-config.json).
