React-Leaflet (legacy v2.x )

Components

⚠️ Before starting to use the following components, make sure to understand the difference between the static and dynamic properties documented in this page.

The properties documented as dynamic properties are updated using the relevant Leaflet setter, other properties will not update the component when they are changed after the component is mounted.
All other properties are passed as the options argument to their corresponding Leaflet element and should work fine for static maps, it is however unlikely that they would get updated if you change them afterwards.

ℹ️ You can directly access the Leaflet element created by a component using this.leafletElement in the component. This leaflet element is usually created in componentWillMount() and therefore accessible in componentDidMount(), except for the Map component where it can only be created after the <div> container is rendered.
You can check out the event handling example to see how to interact with methods exposed by the Leaflet element.

Base components

These components are base classes used by other components. They can be extended to create custom components but should not be used directly.

DivOverlay

Base class extending MapComponent, handling shared logic for the Popup and Tooltip components.

🔍 Source

MapComponent

Base class extending MapEvented to add support for panes.

🔍 Source

MapControl

Base class extending React.Component for controls.
It exposes a leafletElement property to access the Leaflet object created for the control.

🍃 Leaflet Control reference • 🔍 Source

MapEvented

Base class extending React.Component and handling events bindings.
It exposes a leafletElement property to access the Leaflet object created for the component.

🔍 Source

MapLayer

Base class extending MapComponent, handling adding the layer to the map and removing it when relevant. It exposes the layerContainer property, to be used by extending classes to access their containing layer.

🍃 Leaflet Layer reference • 🔍 Source

Path

Base class extending MapLayer with the following methods:

  • getPathOptions(object props): object: filters the input props and return a new object of Path options properties.
  • setStyle(object options = {}): void: alias to the Leaflet element setStyle().
  • setStyleIfChanged(object fromProps, object toProps): void: extracts the Path options of the two arguments, and calls setStyle() with the new options if different from the previous ones.

Dynamic properties

  • animate: boolean (optional): If true, panning will always be animated if possible. Defaults to false.
  • duration: number (optional): Duration of animated panning, in seconds. Defaults to 0.25.
  • easeLinearity: number (optional): The curvature factor of panning animation easing (third parameter of the Cubic Bezier curve). 1.0 means linear animation, and the smaller this number, the more bowed the curve. Defaults to 0.25.
  • noMoveStart: boolean (optional): If true, panning won't fire movestart event on start (used internally for panning inertia). Defaults to false.
  • bounds: bounds (optional): A rectangle for the map to contain. It will be centered, and the map will zoom in as close as it can while still showing the full bounds. Changes are compared using the 🍃 equals() method of LatLngBounds.
  • boundsOptions: Object (optional): Options passed to the fitBounds() method.
  • boxZoom: boolean (optional): If true, the map can be zoomed to a rectangular area specified by dragging the mouse while pressing the shift key. Defaults to true.
  • center: latLng (optional if viewport is provided with a center value): Center of the map. Changes are compared by value, so [51.0, 0.0] is considered the same as {lat: 51, lng: 0}.
  • className: string (optional): className property of the <div> container for the map.
  • doubleClickZoom: boolean | string (optional): If true, 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. Defaults to true.
  • dragging: boolean (optional): If true, allows the map to be draggable with mouse/touch. Defaults to true.
  • keyboard: boolean (optional): If true, allows users to navigate the map with keyboard arrows and control zoom with +/- keys. Defaults to true.
  • maxBounds: bounds (optional)
  • onViewportChange: (viewport: {center: ?[number, number], zoom: ?number}) => void (optional): fired continuously as the viewport changes.
  • onViewportChanged: (viewport: {center: ?[number, number], zoom: ?number}) => void (optional): fired after the viewport changed.
  • style: Object (optional): style property of the <div> container for the map.
  • scrollWheelZoom: boolean | string (optional): If true or center, allows the map to 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. Defaults to true.
  • useFlyTo: boolean (optional): boolean to control whether to use flyTo functions for bounds and center. If false map.fitBounds and map.setView will be used. If true map.flyToBounds and map.flyTo will be used. Defaults to false.
  • tap: boolean (optional): If true, enables mobile hacks for supporting instant taps (fixing 200ms click delay on iOS/Android) and touch holds (fired as contextmenu events). Defaults to true.
  • touchZoom: boolean | string (optional): If true or center, allows the map to be zoomed by touch-dragging with two fingers. If passed 'center', it will zoom to the center of the view regardless of where the touch events (fingers) were. Enabled for touch-capable web browsers except for old Androids.
  • viewport: viewport (optional): sets the viewport based on the provided value or the center and zoom properties.
  • zoom: number (optional if viewport is provided with a zoom value)

Other properties

  • id: string (optional): The ID of the <div> container for the map.
  • whenReady: () => void (optional): A function called as soon as the map is ready, see 🍃 Leaflet's documentation for more information.

Manipulating the viewport

React-Leaflet provides two different ways of manipulating the viewport (the map's center and zoom), either setting the center and zoom properties, or the viewport one. These properties are not exclusive, for example providing both the center and a viewport containing the zoom value would work as expected.

The center and zoom properties are compared by values. This means for React-Leaflet setting the center to [51, 0] is the same as {lat: 51, lng: 0}, if you change the center property from one to the other, it would have no effect, because the values are the same. This is a technical choice made to support common use cases when layers are added to the map, but the map's viewport shouldn't be reset to its original position, the viewport will only change when the provided center or zoom values are different from the ones previously provided, whatever the current map viewport is.
These changes can be tracked using the move and moveend events, so your component can store the current center and zoom values as the user interacts with the map, and render these updated values so that the state of your component matches the viewport of the map. This means you can reset the map to any position by updating the state of your component.
The viewport, on the other hand, is compared by reference, meaning providing a different object, whatever its values, will trigger the viewport change logic. It is for example possible the do <Map center={[51,0]} zoom={10} viewport={{}}> to reset the viewport to the provided center and zoom, because the viewport is a newly created object, and being empty will default it to the center and zoom properties. Providing <Map center={[51,0]} zoom={10} viewport={null}> is equivalent to not providing the viewport property and will perform no change.

React-Leaflet provides the onViewportChange and onViewportChanged callbacks to help apply this behavior, you can see an example usage below:

type Viewport = {
  center: [number, number],
  zoom: number,
}

type Props = {
  viewport: Viewport,
}

type State = {
  viewport: Viewport,
}

class MyMap extends Component<Props, State> {
  constructor(props: Props) {
    // Initialize the viewport to the one provided in props
    this.state = {
      viewport: props.viewport,
    }
  }

  componentWillReceiveProps({ viewport }: Props) {
    // When the provided viewport changes, apply it
    if (viewport !== this.props.viewport) {
      this.setState({ viewport })
    }
  }

  onClickReset = () => {
    // Reset to position provided in props
    this.setState({ viewport: this.props.viewport })
  }

  onViewportChanged = (viewport: Viewport) => {
    // The viewport got changed by the user, keep track in state
    this.setState({ viewport })
  }

  render() {
    return (
      <Map
        onClick={this.onClickReset}
        onViewportChanged={this.onViewportChanged}
        viewport={this.state.viewport}>
        ...
      </Map>
    )
  }
}
