Datasette plugin that replaces any GeoJSON column values with a Leaflet map
Install this plugin in the same environment as Datasette.
$ datasette install datasette-leaflet-geojson
Any columns containing valid GeoJSON strings will have their contents replaced with a Leaflet map when they are displayed in the Datasette interface.
You can try this plugin out at https://calands.datasettes.com/calands/superunits_with_maps
By default this plugin displays maps for the first ten rows, and shows a "Click to load map" prompt for rows past the first ten.
You can change this limit using the default_maps_to_load plugin configuration setting. Add this to your metadata.json:
{
"plugins": {
"datasette-leaflet-geojson": {
"default_maps_to_load": 20
}
}
}Then run Datasette with datasette mydb.db -m metadata.json.
