Plugin options

Pass options to the geo plugin via Yasgui's standard plugin-config slot:

const yasgui = new Yasgui(document.getElementById('yasgui'), {
  yasr: {
    pluginOrder: ['table', 'response', 'geo'],
    defaultPlugin: 'geo',
    plugins: {
      geo: {
        defaultColor: '#ff5722',
        defaultBasemap: 'CartoDB Voyager',
        initialView: { center: [48.8566, 2.3522], zoom: 11 },
        maxZoom: 18,
        minHeight: 600,
        latLonAutoDetect: true,
        // Replace the bundled basemaps entirely:
        basemaps: {
          'My tiles': L.tileLayer('https://my.tiles/{z}/{x}/{y}.png'),
        },
      },
    },
  },
});

Available options

Option	Type	Default	Description
defaultColor	string (CSS color)	#3388ff	Color used for features without a ?wktColor binding.
defaultBasemap	string	'openStreetMap'	Name of the basemap to activate at startup. Must be a key of basemaps.
initialView	{ center: [lat, lon], zoom: number }	Belgium @ 5	Map center and zoom when no features are present.
maxZoom	number	14	Upper bound applied when auto-fitting bounds to features.
minHeight	number (px)	500	Minimum height of the map container.
latLonAutoDetect	boolean	true	Auto-detect numeric lat/lon column pairs and synthesize a WKT POINT column.
basemaps	{ [name]: L.TileLayer }	built-in	Replace the bundled basemap dictionary.
styleControl	boolean	true	Show the compact style control for default color, opacity, fill, stroke width and marker radius.
styleStorageKey	string | null	query hash	Override the localStorage key used to persist style-control values.
simplifyTolerance	number	0	Initial turf-simplify tolerance in degrees.
simplifyControl	boolean	true	Show a live simplification tolerance slider.
simplifyMaxTolerance	number	0.05	Maximum tolerance exposed by the slider.
simplifyStep	number	0.0001	Slider step size.
timeSlider	boolean	true	Show a temporal slider when result rows contain time/date-like bindings.
timeBindingNames	string[] | null	common names	Override temporal binding names (time, date, datetime, timestamp, start, startDate).
timeMode	'cumulative' | 'instant'	'cumulative'	Show all features up to the selected time, or only features at the exact selected time.
permalink	boolean	false	Persist center, zoom, basemap and visible geometry columns in the URL hash.

Styling

The style control persists default visual settings in localStorage, keyed by the current endpoint/query when YASQE is available. A per-row ?wktColor binding still overrides the selected default color for that feature.

Simplification

The simplification slider adjusts turf-simplify tolerance for line and polygon features. Points are never simplified. A value of 0 disables simplification.

Time Slider

When result rows contain a ?time, ?date, ?datetime, ?timestamp, ?start, or ?startDate binding, the plugin displays a time slider. The default cumulative mode shows all dated features up to the selected value; undated features remain visible.

Convention-based per-feature controls

Bindings the plugin recognizes when present in result rows:

Binding	Effect
?wktColor	Override fill/stroke color for that feature.
?wktLabel	Plain-text popup content (replaces the default key/value table).
?wktTooltip	Hover tooltip text.
