@reve99 please set your route to * localhost:8080,over_http
Start it npm run start
change before start Grip (line 6 of pushpin_over_http.ks) and WebSocket (index.html) uris to point to your pushpin instance.
start server npm run start
so load index.html in any browser and click on Run WebSocket, that will connect to pushpin and sent a ping message, server will answer you with a pong, also you could do curl -XGET http://localhost:8080/ws?connID=<your-connID>&text=anything and see that message on your console of browser that came from websocket.
