For clients that would like to be pushed data, support Server-Sent Events.

See e.g. https://medium.com/@tdenton8772/streaming-api-design-using-python-and-javascript-1b0ce8adb703

This involves some design effort e.g. how to we trigger push events to waiting clients when the spot list gets added to? Do we support filters in this endpoint, and if so how do we remember what clients we have attached and what query parameters they used?

Once we add support for this, we should also update the built-in front-end to use it.

TODO:

  • Is something stopping spots coming into the main server?
  • Find a way to improve ordering when new spots arrive? They should not necessarily go at the top due to the way we are only polling e.g. POTA every 2 minutes but Cluster spots come in live.
  • Run/Stop button
