The service requires a running server with an implemented
editron-sync-server
In your editron application
npm install editron-sync-service --save
and setup like
const EditronController = require("editron-core/Controller");
const controller = new EditronController(schema, data);
const SyncService = require("editron-sync-service/SyncService");
const syncService = new SyncService(controller);
syncService.connect(urlToSynServer, uniqueId);
Additionally you may add any component like
const UsersIcon = require("editron-sync-service/components/usersicon");
const users = new UsersIcon(controller, syncService, $targetHTMLNode);
