🌟 [EPIC] Map – Optimizations

[Tirokk]

🚀 Feature

Map – Optimizations.

Todo

• add clustering (as examples see https://www.alpengummi.at/kaufen/ and https://en.nearbywiki.org/map/)
• map search point has the same color as groups, see 🐛 [Bug] Map - search point has same color as groups #5980
• users without descriptions have null on map shown, see 🐛 [Bug] Map - users without descriptions have null on map shown #5979
• have nicer markers?
  • the loaded is not the one used by default markers
    • what you can see if you enter a location in the search
  • may have different icons for the user, users, and groups
  • may be as SVG, but this must be added by another technic
• have a legend?
• optimize overlap of icons (and text labels?)
• get the currentUserLocation direct in the currentUser store?
• divers warnings in the browser console
• solve or create issues
  • bug: as user we can not delete our location
    • have the location edit in the user settings like in the group settings
  • 🐛 [Bug] Webapp - Cache/store issue with user location on the map #6320
  • 🐛 [Bug] Location setting is wrongly mapped in some cases #7239
  • optimize query of users and groups locations
    • to avoid query all of the users and groups, but just the visible
    • create own Cypher and optionally query location directly in user and group resolvers?
  • to make the position a little more precise, for example:
    • in large cities, create the possibility of entering the postal code or a district of the city
    • in villages, create the possibility of entering an address (street, place name, bus station)
  • (see 🌟 [EPIC] Map – Optimizations #5901 ) map visibility (for later):
    • even if a user is not logged in somehow defined users and groups can be seen on the map
