Map
The Map
object represents the map on your page. It exposes methods
and properties that enable you to programmatically change the map,
and fires events as users interact with it.
You create a Map
by specifying a container
and other options.
Then Mapbox GL JS initializes the map on the page and returns your Map
object.
Parameters
(Object)
Name | Description |
---|---|
options.accessToken string default: null | If specified, map will use this
token
instead of the one defined in
mapboxgl.accessToken
.
|
options.antialias boolean default: false | If
true
, the gl context will be created with
MSAA antialiasing
, which can be useful for antialiasing custom layers. This is
false
by default as a performance optimization.
|
options.attributionControl boolean default: true | If
true
, an
AttributionControl
will be added to the map.
|
options.bearing number default: 0 | The initial
bearing
(rotation) of the map, measured in degrees counter-clockwise from north. If
bearing
is not specified in the constructor options, Mapbox 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
.
|
options.bearingSnap number default: 7 | 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.
|
options.bounds LngLatBoundsLike default: null | The initial bounds of the map. If
bounds
is specified, it overrides
center
and
zoom
constructor options.
|
options.boxZoom boolean default: true | If
true
, the "box zoom" interaction is enabled (see
BoxZoomHandler
).
|
options.center LngLatLike default: [0,0] | The initial geographical
centerpoint
of the map. If
center
is not specified in the constructor options, Mapbox 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: Mapbox GL uses longitude, latitude coordinate order (as opposed to latitude, longitude) to match GeoJSON.
|
options.clickTolerance number default: 3 | 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). |
options.collectResourceTiming boolean default: false | 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.
|
options.config Object default: null | The initial configuration options for the style fragments. Each key in the object is a fragment ID (e.g.,
basemap
) and each value is a configuration object.
|
options.container (HTMLElement | string) | The HTML element in which Mapbox GL JS will render the map, or the element's string
id
. The specified element must have no children.
|
options.cooperativeGestures boolean? | If
true
, scroll zoom will require pressing the ctrl or ⌘ key while scrolling to zoom map, and touch pan will require using two fingers while panning to move the map. Touch pitch will require three fingers to activate if enabled.
|
options.crossSourceCollisions boolean default: true | 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.
|
options.customAttribution (string | Array<string>) default: null | String or strings to show in an
AttributionControl
. Only applicable if
options.attributionControl
is
true
.
|
options.doubleClickZoom boolean default: true | If
true
, the "double click to zoom" interaction is enabled (see
DoubleClickZoomHandler
).
|
options.dragPan (boolean | Object) default: true | If
true
, the "drag to pan" interaction is enabled. An
Object
value is passed as options to
DragPanHandler#enable
.
|
options.dragRotate boolean default: true | If
true
, the "drag to rotate" interaction is enabled (see
DragRotateHandler
).
|
options.fadeDuration number default: 300 | Controls the duration of the fade-in/fade-out animation for label collisions, in milliseconds. This setting affects all symbol layers. This setting does not affect the duration of runtime styling transitions or raster tile cross-fading. |
options.failIfMajorPerformanceCaveat boolean default: false | If
true
, map creation will fail if the performance of Mapbox GL JS would be dramatically worse than expected (a software renderer would be used).
|
options.fitBoundsOptions Object default: null | A
Map#fitBounds
options object to use
only
when fitting the initial
bounds
provided above.
|
options.hash (boolean | string) default: false | 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,
http://path/to/my/page.html#2.59/39.26/53.07/-24.1/60
.
An additional string may optionally be provided to indicate a parameter-styled hash,
for example
http://path/to/my/page.html#map=2.59/39.26/53.07/-24.1/60&foo=bar
, where
foo
is a custom parameter and
bar
is an arbitrary hash distinct from the map hash.
|
options.interactive boolean default: true | If
false
, no mouse, touch, or keyboard listeners will be attached to the map, so it will not respond to interaction.
|
options.keyboard boolean default: true | If
true
, keyboard shortcuts are enabled (see
KeyboardHandler
).
|
options.language ( default: null | A string with a BCP 47 language tag, or an array of such strings representing the desired languages used for the map's labels and UI components. Languages can only be set on Mapbox vector tile sources.
By default, GL JS will not set a language so that the language of Mapbox tiles will be determined by the vector tile source's TileJSON.
Valid language strings must be a
BCP-47 language code
. Unsupported BCP-47 codes will not include any translations. Invalid codes will result in an recoverable error.
If a label has no translation for the selected language, it will display in the label's local language.
If option is set to
auto
, GL JS will select a user's preferred language as determined by the browser's
window.navigator.language
property.
If the
locale
property is not set separately, this language will also be used to localize the UI for supported languages.
|
options.locale Object default: null | A patch to apply to the default localization table for UI strings such as 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).
|
options.localFontFamily string default: null | Defines a CSS font-family for locally overriding generation of all glyphs. Font settings from the map's style will be ignored, except for font-weight keywords (light/regular/medium/bold). If set, this option overrides the setting in localIdeographFontFamily. |
options.localIdeographFontFamily string default: 'sans-serif' | Defines a CSS font-family for locally overriding generation of glyphs in the 'CJK Unified Ideographs', 'Hiragana', 'Katakana', 'Hangul Syllables' and 'CJK Symbols and Punctuation' ranges.
In these ranges, 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. Note that
Mapbox Studio
sets this value to
false
by default.
The purpose of this option is to avoid bandwidth-intensive glyph server requests. For an example of this option in use, see
Use locally generated ideographs
.
|
options.logoPosition string default: 'bottom-left' | A string representing the position of the Mapbox wordmark on the map. Valid options are
top-left
,
top-right
,
bottom-left
,
bottom-right
.
|
options.maxBounds LngLatBoundsLike default: null | If set, the map will be constrained to the given bounds. |
options.maxPitch number default: 85 | The maximum pitch of the map (0-85). |
options.maxTileCacheSize number default: null | The maximum number of tiles stored in the tile cache for a given source. If omitted, the cache will be dynamically sized based on the current viewport. |
options.maxZoom number default: 22 | The maximum zoom level of the map (0-24). |
options.minPitch number default: 0 | The minimum pitch of the map (0-85). |
options.minTileCacheSize number default: null | The minimum number of tiles stored in the tile cache for a given source. Larger viewports use more tiles and need larger caches. Larger viewports are more likely to be found on devices with more memory and on pages where the map is more important. If omitted, the cache will be dynamically sized based on the current viewport. |
options.minZoom number default: 0 | The minimum zoom level of the map (0-24). |
options.performanceMetricsCollection boolean default: true | If
true
, mapbox-gl will collect and send performance metrics.
|
options.pitch number default: 0 | The initial
pitch
(tilt) of the map, measured in degrees away from the plane of the screen (0-85). If
pitch
is not specified in the constructor options, Mapbox 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
.
|
options.pitchWithRotate boolean default: true | If
false
, the map's pitch (tilt) control with "drag to rotate" interaction will be disabled.
|
options.preserveDrawingBuffer boolean default: false | If
true
, the map's canvas can be exported to a PNG using
map.getCanvas().toDataURL()
. This is
false
by default as a performance optimization.
|
options.projection ProjectionSpecification default: 'mercator' | The
projection
the map should be rendered in.
Supported projections are:
|
options.refreshExpiredTiles boolean default: true | If
false
, the map won't attempt to re-request tiles once they expire per their HTTP
cacheControl
/
expires
headers.
|
options.renderWorldCopies boolean default: true | If
true
, multiple copies of the world will be rendered side by side beyond -180 and 180 degrees longitude. If set to
false
:
|
options.respectPrefersReducedMotion boolean default: true | If set to
true
, the map will respect the user's
prefers-reduced-motion
browser setting and apply a reduced motion mode, minimizing animations and transitions. When set to
false
, the map will always ignore the
prefers-reduced-motion
settings, regardless of the user's preference, making all animations essential.
|
options.scrollZoom (boolean | Object) default: true | If
true
, the "scroll to zoom" interaction is enabled. An
Object
value is passed as options to
ScrollZoomHandler#enable
.
|
options.spriteFormat ( default: 'auto' | The format of the image sprite to use. If set to
'auto'
, vector iconset will be used for all mapbox-hosted sprites and raster sprite for all custom URLs.
|
options.style (Object | string) default: 'mapbox://styles/mapbox/standard' | The map's Mapbox style. This must be an a JSON object conforming to
the schema described in the
Mapbox Style Specification
, or a URL
to such JSON. Can accept a null value to allow adding a style manually.
To load a style from the Mapbox API, you can use a URL of the form
Tilesets hosted with Mapbox can be style-optimized if you append |
options.testMode boolean default: false | Silences errors and warnings generated due to an invalid accessToken, useful when using the library to write unit tests. |
options.touchPitch (boolean | Object) default: true | If
true
, the "drag to pitch" interaction is enabled. An
Object
value is passed as options to
TouchPitchHandler
.
|
options.touchZoomRotate (boolean | Object) default: true | If
true
, the "pinch to rotate and zoom" interaction is enabled. An
Object
value is passed as options to
TouchZoomRotateHandler#enable
.
|
options.trackResize boolean default: true | If
true
, the map will automatically resize when the browser window resizes.
|
options.transformRequest RequestTransformFunction default: 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 a
RequestParameters
object with a
url
property and optionally
headers
and
credentials
properties.
|
options.worldview string default: null | Sets the map's worldview. A worldview determines the way that certain disputed boundaries are rendered. By default, GL JS will not set a worldview so that the worldview of Mapbox tiles will be determined by the vector tile source's TileJSON. Valid worldview strings must be an ISO alpha-2 country code . Unsupported ISO alpha-2 codes will fall back to the TileJSON's default worldview. Invalid codes will result in a recoverable error. |
options.zoom number default: 0 | The initial
zoom
level of the map. If
zoom
is not specified in the constructor options, Mapbox 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
.
