L.Map

Map

The central class of the API — it is used to create a map on a page and manipulate it.

Usage example

// initialize the map on the "map" div with a given center and zoom
var map = L.map('map', {
	center: [51.505, -0.09],
	zoom: 17
});

Creation

Factory	Description
`L.map( <HTMLElement\|String> id, <Map options> options? )`	Instantiates a map object given a div element (or its id) and optionally an object literal with map options described below.

Options

Map State Options

Option	Type	Default	Description
`center`	`LatLng`	`null`	Initial geographical center of the map.
`zoom`	`Number`	`null`	Initial map zoom.
`layers`	`ILayer[]`	`null`	Layers that will be added to the map initially.
`minZoom`	`Number`	`null`	Minimum zoom level of the map. Overrides any `minZoom` set on map layers.
`maxZoom`	`Number`	`null`	Maximum zoom level of the map. This overrides any `maxZoom` set on map layers.
`maxBounds`	`LatLngBounds`	`null`	When this option is set, the map restricts the view to the given geographical bounds, bouncing the user back when he tries to pan outside the view. To set the restriction dynamically, use setMaxBounds method.
`crs`	`CRS`	`L.CRS. EPSG3857`	Coordinate Reference System to use. Don't change this if you're not sure what it means.

Interaction Options

Option	Type	Default	Description
`dragging`	`Boolean`	`true`	Whether the map be draggable with mouse/touch or not.
`touchZoom`	`Boolean`	`true`	Whether the map can be zoomed by touch-dragging with two fingers.
`scrollWheelZoom`	`Boolean`	`true`	Whether the map can be zoomed by using the mouse wheel. If passed `'center'`, it will zoom to the center of the view regardless of where the mouse was.
`doubleClickZoom`	`Boolean`	`true`	Whether the map can be zoomed in by double clicking on it and zoomed out by double clicking while holding shift. If passed `'center'`, double-click zoom will zoom to the center of the view regardless of where the mouse was.
`boxZoom`	`Boolean`	`true`	Whether the map can be zoomed to a rectangular area specified by dragging the mouse while pressing shift.
`tap`	`Boolean`	`true`	Enables mobile hacks for supporting instant taps (fixing 200ms click delay on iOS/Android) and touch holds (fired as `contextmenu` events).
`tapTolerance`	`Number`	`15`	The max number of pixels a user can shift his finger during touch for it to be considered a valid tap.
`trackResize`	`Boolean`	`true`	Whether the map automatically handles browser window resize to update itself.
`worldCopyJump`	`Boolean`	`false`	With this option enabled, the map tracks when you pan to another "copy" of the world and seamlessly jumps to the original one so that all overlays like markers and vector layers are still visible.
`closePopupOnClick`	`Boolean`	`true`	Set it to `false` if you don't want popups to close when user clicks the map.
`bounceAtZoomLimits`	`Boolean`	`true`	Set it to `false` if you don't want the map to zoom beyond min/max zoom and then bounce back when pinch-zooming.

Keyboard Navigation Options

Option	Type	Default	Description
`keyboard`	`Boolean`	`true`	Makes the map focusable and allows users to navigate the map with keyboard arrows and `+`/`-` keys.

Methods for Modifying Map State

Method	Returns	Description
`setView( <LatLng> center, <Number> zoom?, <zoom/pan options> options? )`	`this`	Sets the view of the map (geographical center and zoom) with the given animation options.
`setZoom( <Number> zoom, <zoom options> options? )`	`this`	Sets the zoom of the map.
`zoomIn( <Number> delta?, <zoom options> options? )`	`this`	Increases the zoom of the map by `delta` (`1` by default).
`zoomOut( <Number> delta?, <zoom options> options? )`	`this`	Decreases the zoom of the map by `delta` (`1` by default).
`setZoomAround( <LatLng> latlng, <Number> zoom, <zoom options> options? )`	`this`	Zooms the map while keeping a specified point on the map stationary (e.g. used internally for scroll zoom and double-click zoom).
`fitBounds( <LatLngBounds> bounds, <fitBounds options> options? )`	`this`	Sets a map view that contains the given geographical bounds with the maximum zoom level possible.
`fitWorld( <fitBounds options> options? )`	`this`	Sets a map view that mostly contains the whole world with the maximum zoom level possible.
`panTo( <LatLng> latlng, <pan options> options? )`	`this`	Pans the map to a given center. Makes an animated pan if new center is not more than one screen away from the current one.
`panInsideBounds( <LatLngBounds> bounds, <pan options> options? )`	`this`	Pans the map to the closest view that would lie inside the given bounds (if it's not already), controlling the animation using the options specific, if any.
`panBy( <Point> point, <pan options> options? )`	`this`	Pans the map by a given number of pixels (animated).
`invalidateSize( <Boolean> animate )`	`this`	Checks if the map container size changed and updates the map if so — call it after you've changed the map size dynamically, also animating pan by default.
`invalidateSize( <zoom/pan options> options )`	`this`	Checks if the map container size changed and updates the map if so — call it after you've changed the map size dynamically, also animating pan by default. If `options.pan` is `false`, panning will not occur. If `options.debounceMoveend` is `true`, it will delay `moveend` event so that it doesn't happen often even if the method is called many times in a row.
`setMaxBounds( <LatLngBounds> bounds`	`this`	Restricts the map view to the given bounds (see map maxBounds option).
`locate( <Locate options> options? )`	`this`	Tries to locate the user using the Geolocation API, firing a `locationfound` event with location data on success or a `locationerror` event on failure, and optionally sets the map view to the user's location with respect to detection accuracy (or to the world view if geolocation failed). See Locate options for more details.
`stopLocate()`	`this`	Stops watching location previously initiated by `map.locate({watch: true})` and aborts resetting the map view if `map.locate` was called with `{setView: true}`.
`remove()`	`this`	Destroys the map and clears all related event listeners.

Pan options

Option	Type	Default	Description
`animate`	`Boolean`	`-`	If `true`, panning will always be animated if possible. If `false`, it will not animate panning, either resetting the map view if panning more than a screen away, or just setting a new offset for the map pane (except for `panBy` which always does the latter).

`easeLinearity`	`Number`	`0.25`	The curvature factor of panning animation easing (third parameter of the Cubic Bezier curve). 1.0 means linear animation, the less the more bowed the curve.
`noMoveStart`	`Boolean`	`false`	If `true`, panning won't fire `movestart` event on start (used internally for panning inertia).

Zoom options

Option	Type	Default	Description
`animate`	`Boolean`	`-`	If not specified, zoom animation will happen if the zoom origin is inside the current view. If `true`, the map will attempt animating zoom disregarding where zoom origin is. Setting `false` will make it always reset the view completely without animation.

fitBounds options

The same as zoom/pan options and additionally:

Option	Type	Default	Description
`paddingTopLeft`	`Point`	`[0, 0]`	Sets the amount of padding in the top left corner of a map container that shouldn't be accounted for when setting the view to fit bounds. Useful if you have some control overlays on the map like a sidebar and you don't want them to obscure objects you're zooming to.
`paddingBottomRight`	`Point`	`[0, 0]`	The same for bottom right corner of the map.
`padding`	`Point`	`[0, 0]`	Equivalent of setting both top left and bottom right padding to the same value.
`maxZoom`	`Number`	`null`	The maximum possible zoom to use.
