Have you ever need to mock some sort of websocket endpoint during the early stage of development of an application? I do. I could easily mock REST apis with json-server, but then I had to wrote something allowing me to mock sokects also.

I've encountered many problems, for example when getCurrentPosition was always returning me a cached position object, despite of my configurations. For this reason I wrote a getLocation function that tries to incapsulate all the code needed to get a reliable position with a fallback to low accuracy mode.
