Configuration

The config of the FacilMap server can be set either by using environment variables (useful for docker) or by editing config.env.

Variable	Required	Default	Meaning
USER_AGENT	*		Will be used for all HTTP requests (search, routing, GPX/KML/OSM/GeoJSON files). You better provide your e-mail address in here.
APP_NAME			If specified, will replace “FacilMap” as the name of the app throughout the UI.
TRUST_PROXY			Whether to trust the X-Forwarded-* headers. Can be true or a comma-separated list of IP subnets (see the express documentation). Currently only used to calculate the base URL for the opensearch.xml file.
BASE_URL			If TRUST_PROXY does not work for your particular setup, you can manually specify the base URL where FacilMap can be publicly reached here.
HOST			The ip address to listen on (leave empty to listen on all addresses)
PORT		8080	The port to listen on.
DB_TYPE		mysql	The type of database. Either mysql, postgres, mariadb, sqlite, or mssql.
DB_HOST		localhost	The host name of the database server.
DB_PORT			The port of the database server (optional).
DB_NAME		facilmap	The name of the database.
DB_USER		facilmap	The username to connect to the database with.
DB_PASSWORD		facilmap	The password to connect to the database with.
ORS_TOKEN			OpenRouteService API key. If not specified, advanced routing settings will not be shown.
MAPBOX_TOKEN			Mapbox API key. If neither this nor ORS_TOKEN are specified, the routing tab and any routing options will be hidden.
MAXMIND_USER_ID			MaxMind user ID.
MAXMIND_LICENSE_KEY			MaxMind license key.
LIMA_LABS_TOKEN			Lima Labs API key
HIDE_COMMERCIAL_MAP_LINKS			Set to 1 to hide the links to Google/Bing Maps in the “Map style” menu.
CUSTOM_CSS_FILE			The path of a CSS file that should be included (see more details below).
NOMINATIM_URL		https://nominatim.openstreetmap.org	The URL to the Nominatim server (used to search for places).
OPEN_ELEVATION_URL		https://api.open-elevation.com	The URL to the Open Elevation server (used to look up the elevation for markers).
OPEN_ELEVATION_THROTTLE_MS		1000	The minimum time between two requests to the Open Elevation API. Set to 0 if you are using your own self-hosted instance of Open Elevation.
OPEN_ELEVATION_MAX_BATCH_SIZE		200	The maximum number of points to resolve in one request through the Open Elevation API. Set this to 1000 if you are using your own self-hosted Open Elevation instance.

FacilMap makes use of several third-party services that require you to register (for free) and generate an API key:

• Mapbox and OpenRouteService are used for calculating routes. Mapbox is used for basic routes, OpenRouteService is used when custom route mode settings are made. If these API keys are not defined, calculating routes will fail.
• Maxmind provides a free database that maps IP addresses to approximate locations. FacilMap downloads this database to decide the initial map view for users (IP addresses are looked up in FacilMap’s copy of the database, on IP addresses are sent to Maxmind). This API key is optional, if it is not set, the default view will be the whole world.
• Lima Labs is used for nicer and higher resolution map tiles than Mapnik. The API key is optional, if it is not set, Mapnik will be the default map style instead.

Custom CSS file

To include a custom CSS file in the UI, set the CUSTOM_CSS_FILE environment variable to the file path.

When running FacilMap with docker, you can mount your CSS file as a volume into the container, for example with the following docker-compose configuration:

		environment:
			CUSTOM_CSS_FILE: /opt/facilmap/custom.css
		volumes:
			- ./custom.css:/opt/facilmap/custom.css

Your custom CSS file will be included in the map UI and in the table export. You can distinguish between the two by using the html.fm-facilmap-map and html.fm-facilmap-table selectors.
