Marker

React component that wraps Marker.

import * as React from 'react';
import Map, {Marker} from 'react-map-gl';

function App() {
  return <Map
    initialViewState={{
      longitude: -100,
      latitude: 40,
      zoom: 3.5
    }}
    mapStyle="mapbox://styles/mapbox/streets-v9"
  >
    <Marker longitude={-100} latitude={40} anchor="bottom" >
      <img src="./pin.png" />
    </Marker>
  </Map>;
}

If Marker is mounted with child components, then its content will be rendered to the specified location. If it is mounted with no content, then a default marker will be used.

Properties

Render options

anchor: 'center' | 'left' | 'right' | 'top' | 'bottom' | 'top-left' | 'top-right' | 'bottom-left' | 'bottom-right'

Default: 'center'

A string indicating the part of the Marker that should be positioned closest to the coordinate set via longitude and latitude.

color: string

Default: '#3FB1CE'

The color to use for the default marker if the component contains no content.

clickTolerance: number

Default: null (inherits Map's clickTolerance)

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

draggable: boolean

Default: false

If true, the marker is able to be dragged to a new position on the map.

latitude: number

Required. The latitude of the anchor location.

longitude: number

Required. The longitude of the anchor location.

offset: PointLike

Default: null

The offset in pixels as a PointLike object to apply relative to the element's center. Negatives indicate left and up.

pitchAlignment: 'map' | 'viewport' | 'auto'

Default: 'auto'

• map aligns the Marker to the plane of the map.
• viewport aligns the Marker to the plane of the viewport.
• auto automatically matches the value of rotationAlignment.

rotation: number

Default: 0

The rotation angle of the marker in degrees, relative to its rotationAlignment setting. A positive value will rotate the marker clockwise.

rotationAlignment: 'map' | 'viewport' | 'auto'

Default: 'auto'

• map aligns the Marker's rotation relative to the map, maintaining a bearing as the map rotates.
• viewport aligns the Marker's rotation relative to the viewport, agnostic to map rotations.
• auto is equivalent to viewport.

scale: number

Default: 1

The scale to use for the default marker if the component contains no content. The default scale (1) corresponds to a height of 41px and a width of 27px.

This prop is not reactive (only used when the marker is mounted).

style: CSSProperties

CSS style override that applies to the marker's container.
