## Properties[](#properties-1)

### `Optional`anisotropicFilterPitch[](#anisotropicfilterpitch)

anisotropicFilterPitch?: number | null

The pitch above which to apply anisotropic filtering to the map's raster layers (0-180).

#### Default Value[](#default-value)

```typescript
20
```

### `Optional`aroundCenter[](#aroundcenter)

aroundCenter?: boolean

Determines the rotation interaction model:

-   When true: Uses "Orbital" logic where rotation is relative to the pivot center. Dragging right at the top rotates clockwise, while dragging right at the bottom rotates counter-clockwise (like spinning a physical globe).
-   When false: Uses "Linear" logic where horizontal mouse movement translates directly to bearing change regardless of cursor position.

### `Optional`attributionControl[](#attributioncontrol)

attributionControl?: false | [AttributionControlOptions](https://docs.maptiler.com/sdk-js/api-reference/types/Externals.AttributionControlOptions/)

If set, an [AttributionControl](https://docs.maptiler.com/sdk-js/api-reference/classes/Externals.AttributionControl/) will be added to the map with the provided options. To disable the attribution control, pass `false`. !!! note Showing the logo of MapLibre is not required for using MapLibre.

#### Default Value[](#default-value-1)

```typescript
compact: true, customAttribution: "MapLibre ...".
```

### `Optional`bearing[](#bearing)

bearing?: number

The initial bearing (rotation) of the map, measured in degrees counter-clockwise from north. If `bearing` is not specified in the constructor options, MapLibre GL JS will look for it in the map's style object. If it is not specified in the style, either, it will default to `0`.

#### Default Value[](#default-value-2)

```typescript
0
```

### `Optional`bearingSnap[](#bearingsnap)

bearingSnap?: number

The threshold, measured in degrees, that determines when the map's bearing will snap to north. For example, with a `bearingSnap` of 7, if the user rotates the map within 7 degrees of north, the map will automatically snap to exact north.

#### Default Value[](#default-value-3)

```typescript
7
```

### `Optional`bounds[](#bounds)

bounds?: [LngLatBoundsLike](https://docs.maptiler.com/sdk-js/api-reference/types/LngLatBoundsLike/)

The initial bounds of the map. If `bounds` is specified, it overrides `center` and `zoom` constructor options.

### `Optional`boxZoom[](#boxzoom)

boxZoom?: boolean | [BoxZoomHandlerOptions](https://docs.maptiler.com/sdk-js/api-reference/types/BoxZoomHandlerOptions/)

If `true`, the "box zoom" interaction is enabled (see [BoxZoomHandler](https://docs.maptiler.com/sdk-js/api-reference/classes/Externals.BoxZoomHandler/)). An `Object` value configures [BoxZoomHandler](https://docs.maptiler.com/sdk-js/api-reference/classes/Externals.BoxZoomHandler/) options. If `boxZoomEnd` is provided, the callback runs instead of the default fit-to-box zoom.

#### Default Value[](#default-value-4)

```typescript
true
```

### `Optional`cancelPendingTileRequestsWhileZooming[](#cancelpendingtilerequestswhilezooming)

cancelPendingTileRequestsWhileZooming?: boolean

Determines whether to cancel, or retain, tiles from the current viewport which are still loading but which belong to a farther (smaller) zoom level than the current one.

-   If `true`, when zooming in, tiles which didn't manage to load for previous zoom levels will become canceled. This might save some computing resources for slower devices, but the map details might appear more abruptly at the end of the zoom.
-   If `false`, when zooming in, the previous zoom level(s) tiles will progressively appear, giving a smoother map details experience. However, more tiles will be rendered in a short period of time.

#### Default Value[](#default-value-5)

```typescript
true
```

### `Optional`canvasContextAttributes[](#canvascontextattributes)

canvasContextAttributes?: [WebGLContextAttributesWithType](https://docs.maptiler.com/sdk-js/api-reference/types/WebGLContextAttributesWithType/)

Set of WebGLContextAttributes that are applied to the WebGL context of the map. See [https://developer.mozilla.org/en-US/docs/Web/API/HTMLCanvasElement/getContext](https://developer.mozilla.org/en-US/docs/Web/API/HTMLCanvasElement/getContext) for more details. `contextType` can be set to `webgl2` or `webgl` to force a WebGL version. Not setting it, Maplibre will do it's best to get a suitable context.

#### Default Value[](#default-value-6)

```typescript
antialias: false, powerPreference: 'high-performance', preserveDrawingBuffer: false, failIfMajorPerformanceCaveat: false, desynchronized: false, contextType: 'webgl2withfallback'
```

### `Optional`center[](#center)

center?: [LngLatLike](https://docs.maptiler.com/sdk-js/api-reference/types/LngLatLike/)

The initial geographical centerpoint of the map. If `center` is not specified in the constructor options, MapLibre GL JS will look for it in the map's style object. If it is not specified in the style, either, it will default to `[0, 0]` !!! note MapLibre GL JS uses longitude, latitude coordinate order (as opposed to latitude, longitude) to match GeoJSON.

#### Default Value[](#default-value-7)

```json
[0, 0]
```

### `Optional`centerClampedToGround[](#centerclampedtoground)

centerClampedToGround?: boolean

If true, the elevation of the center point will automatically be set to the terrain elevation (or zero if terrain is not enabled). If false, the elevation of the center point will default to sea level and will not automatically update. Defaults to true. Needs to be set to false to keep the camera above ground when pitch > 90 degrees.

### `Optional`clickTolerance[](#clicktolerance)

clickTolerance?: number

The max number of pixels a user can shift the mouse pointer during a click for it to be considered a valid click (as opposed to a mouse drag).

#### Default Value[](#default-value-8)

```typescript
3
```

### `Optional`collectResourceTiming[](#collectresourcetiming)

collectResourceTiming?: boolean

If `true`, Resource Timing API information will be collected for requests made by GeoJSON and Vector Tile web workers (this information is normally inaccessible from the main Javascript thread). Information will be returned in a `resourceTiming` property of relevant `data` events.

#### Default Value[](#default-value-9)

```typescript
false
```

### container[](#container)

container: [HTMLElement](https://docs.maptiler.com/sdk-js/api-reference/interfaces/Externals.HTMLElement/) | string

### `Optional`cooperativeGestures[](#cooperativegestures)

cooperativeGestures?: [GestureOptions](https://docs.maptiler.com/sdk-js/api-reference/types/GestureOptions/)

If `true` or set to an options object, the map is only accessible on desktop while holding Command/Ctrl and only accessible on mobile with two fingers. Interacting with the map using normal gestures will trigger an informational screen. With this option enabled, "drag to pitch" requires a three-finger gesture. Cooperative gestures are disabled when a map enters fullscreen using [FullscreenControl](https://docs.maptiler.com/sdk-js/api-reference/classes/Externals.FullscreenControl/).

#### Default Value[](#default-value-10)

```typescript
false
```

### `Optional`crossSourceCollisions[](#crosssourcecollisions)

crossSourceCollisions?: boolean

If `true`, symbols from multiple sources can collide with each other during collision detection. If `false`, collision detection is run separately for the symbols in each source.

#### Default Value[](#default-value-11)

```typescript
true
```

### `Optional`doubleClickZoom[](#doubleclickzoom)

doubleClickZoom?: boolean

If `true`, the "double click to zoom" interaction is enabled (see [DoubleClickZoomHandler](https://docs.maptiler.com/sdk-js/api-reference/classes/Externals.DoubleClickZoomHandler/)).

#### Default Value[](#default-value-12)

```typescript
true
```

### `Optional`dragPan[](#dragpan)

dragPan?: boolean | [DragPanOptions](https://docs.maptiler.com/sdk-js/api-reference/types/DragPanOptions/)

If `true`, the "drag to pan" interaction is enabled. An `Object` value is passed as options to [DragPanHandler.enable](https://docs.maptiler.com/sdk-js/api-reference/classes/Externals.DragPanHandler/#enable).

#### Default Value[](#default-value-13)

```typescript
true
```

### `Optional`dragRotate[](#dragrotate)

dragRotate?: boolean

If `true`, the "drag to rotate" interaction is enabled (see [DragRotateHandler](https://docs.maptiler.com/sdk-js/api-reference/classes/Externals.DragRotateHandler/)).

#### Default Value[](#default-value-14)

```typescript
true
```

### `Optional`elevation[](#elevation)

elevation?: number

The elevation of the initial geographical centerpoint of the map, in meters above sea level. If `elevation` is not specified in the constructor options, it will default to `0`.

#### Default Value[](#default-value-15)

```typescript
0
```

### `Optional`experimentalZoomLevelsToOverscale[](#experimentalzoomlevelstooverscale)

experimentalZoomLevelsToOverscale?: number

Allows overzooming by splitting vector tiles after max zoom. Defines the number of zoom level that will overscale from map's max zoom and below. For example if the map's max zoom is 20 and this is set to 3, the zoom levels of 20, 19 and 18 will be overscaled and the rest will be split. When undefined, all zoom levels after source's max zoom will be overscaled. This can help in reducing the size of the overscaling and improve performance in high zoom levels. The drawback is that it changes rendering for polygon centered labels and changes the results of query rendered features.

#### Default Value[](#default-value-16)

```typescript
undefined
```

#### Experimental[](#experimental)

### `Optional`fadeDuration[](#fadeduration)

fadeDuration?: number

Controls the duration of the fade-in/fade-out animation for label collisions after initial map load, in milliseconds. This setting affects all symbol layers. This setting does not affect the duration of runtime styling transitions or raster tile cross-fading.

#### Default Value[](#default-value-17)

```typescript
300
```

### `Optional`fitBoundsOptions[](#fitboundsoptions)

fitBoundsOptions?: [FitBoundsOptions](https://docs.maptiler.com/sdk-js/api-reference/types/FitBoundsOptions/)

A [FitBoundsOptions](https://docs.maptiler.com/sdk-js/api-reference/types/FitBoundsOptions/) options object to use _only_ when fitting the initial `bounds` provided above.

### `Optional`hash[](#hash)

hash?: boolean | string

If `true`, the map's position (zoom, center latitude, center longitude, bearing, and pitch) will be synced with the hash fragment of the page's URL. For example, `https://example.com#2.59/39.26/53.07/-24.1/60`.

An additional string may optionally be provided as an alternative to indicate a parameter-styled hash. For example, passing `hash: "foo"` will produce a hash like `https://example.com#foo=2.59/39.26/53.07/-24.1/60`. This is usefull for allowing multiple maps or other state.

#### Default Value[](#default-value-18)

```typescript
false
```

### `Optional`interactive[](#interactive)

interactive?: boolean

If `false`, no mouse, touch, or keyboard listeners will be attached to the map, so it will not respond to interaction.

#### Default Value[](#default-value-19)

```typescript
true
```

### `Optional`keyboard[](#keyboard)

keyboard?: boolean

If `true`, keyboard shortcuts are enabled (see [KeyboardHandler](https://docs.maptiler.com/sdk-js/api-reference/classes/Externals.KeyboardHandler/)).

#### Default Value[](#default-value-20)

```typescript
true
```

### `Optional`locale[](#locale)

locale?: [Record](https://docs.maptiler.com/sdk-js/api-reference/types/Externals.Record/)<string, string\>

A patch to apply to the default localization table for UI strings, e.g. control tooltips. The `locale` object maps namespaced UI string IDs to translated strings in the target language; see `src/ui/default_locale.js` for an example with all supported string IDs. The object may specify all UI strings (thereby adding support for a new translation) or only a subset of strings (thereby patching the default translation table). For an example, see [https://maplibre.org/maplibre-gl-js/docs/examples/locale-switching/](https://maplibre.org/maplibre-gl-js/docs/examples/locale-switching/) Alternatively, search the official plugins page for plugins related to localization.

#### Default Value[](#default-value-21)

```typescript
null
```

### `Optional`localIdeographFontFamily[](#localideographfontfamily)

localIdeographFontFamily?: string | false

Defines a CSS font-family for locally overriding generation of Chinese, Japanese, and Korean characters. For these characters, font settings from the map's style will be ignored, except for font-weight keywords (light/regular/medium/bold). Set to `false`, to enable font settings from the map's style for these glyph ranges. The purpose of this option is to avoid bandwidth-intensive glyph server requests.

#### See[](#see)

#### Default Value[](#default-value-35)

```typescript
true
```

### `Optional`roll[](#roll)

roll?: number

The initial roll angle of the map, measured in degrees counter-clockwise about the camera boresight. If `roll` is not specified in the constructor options, MapLibre GL JS will look for it in the map's style object. If it is not specified in the style, either, it will default to `0`.

### `Optional`transformConstrain[](#transformconstrain)

transformConstrain?: [TransformConstrainFunction](https://docs.maptiler.com/sdk-js/api-reference/types/TransformConstrainFunction/) | null

A callback that overrides how the map constrains the viewport's lnglat and zoom to respect the longitude and latitude bounds.

#### See[](#see-1)

[Customize the map transform constrain](https://maplibre.org/maplibre-gl-js/docs/examples/customize-the-map-transform-constrain/) Expected to return an object containing center and zoom.

#### Default Value[](#default-value-43)

```typescript
null
```

### `Optional`transformRequest[](#transformrequest)

transformRequest?: [RequestTransformFunction](https://docs.maptiler.com/sdk-js/api-reference/types/RequestTransformFunction/) | null

A callback run before the Map makes a request for an external URL. The callback can be used to modify the url, set headers, or set the credentials property for cross-origin requests. Expected to return an object with a `url` property and optionally `headers` and `credentials` properties.

#### Default Value[](#default-value-44)

```typescript
null
```

### `Optional`validateStyle[](#validatestyle)

validateStyle?: boolean

If false, style validation will be skipped. Useful in production environments due to enabling tree-shaking of the validation code in some environments and minor performance improvements. Disabling this option comes at the cost of less clear error messages

#### Default Value[](#default-value-45)

```typescript
true
```

### `Optional`zoom[](#zoom)

zoom?: number

The initial zoom level of the map. If `zoom` is not specified in the constructor options, MapLibre GL JS will look for it in the map's style object. If it is not specified in the style, either, it will default to `0`.

#### Default Value[](#default-value-46)

```typescript
0
```

### `Optional`zoomSnap[](#zoomsnap)

zoomSnap?: number

The step increment the zoom level will snap to. For example, if `zoomSnap` is 1, the map will snap to whole integers during discrete zoom operations. If set to 0, zooming is continuous.

#### Default Value[](#default-value-47)

```typescript
0
```
