PresenceStore — Client side presence channel handler
The purpose of this class is to connect to the reflector service and provide a consistent view of what everybody else on the channel is "doing", i.e. their state. This supports the real time presence experience in Sanity.
const presenceStore = myConfiguredSanityClient// Subscribe to state changes about all other users on the channelpresenceStorepresence// Report my state to the other clients on the channelpresenceStore// Do this to allow the presence store to notify the others that we left. Uses// navigator.sendBeacon to get the message out even though the window is closing.window;
Format of state reports
The reports from the presence subscription (i.e.
allTheirStates as seen above) will look someting like this:
identity: "<a sanity identity>"session: "<an UUID to identify the browser window>"// and now whatever this client reported to reportMyState:location: "/fnah"activity: "editing"// more of these ...
The order of the reports is consistent between calls, the object identity of each report is identical until it changes, and is always new when it does change.
You don't see your own state reported in this window in the list, but you will see state reported for your identity in other windows.
