Maps
The dealer locator (the dealers module) shows dealers on a map, drawn with Leaflet. The map's code loads in the visitor's browser only when a map scrolls into view.
The tile server #
The background map comes from a tile server, chosen by an admin in Site settings → Maps:
| Choice | What it does |
|---|---|
| OpenStreetMap (the default) | OpenStreetMap's own tiles, credited "© OpenStreetMap contributors" in the visitor's language. Free for light use, under OpenStreetMap's tile usage policy. |
| Another tile server | Any server with an https address holding {z}, {x} and {y}, with its own credit, credit link and closest zoom (1 to 22, 18 by default). A custom server without a usable address shows no tiles rather than falling back to another. |
| None | Markers only. |
Visitors' browsers load the tiles straight from that server. For a busy site, use a commercial tile service or a server of your own.
Turning tiles off #
MAP_TILES=off in the environment draws markers only, whatever Site settings say, and no visitor's browser asks a tile server. The end-to-end tests set it, so they never depend on the internet; it also suits a copy of the site without internet access.
