    Animation Plugin for Leaflet.js

    npm version

    General information

    A leaflet plugin which allows users to apply animation.



    npm install --save leaflet.motion


    yarn add leaflet.motion


    Include script:

    <script src="dist/leaflet.motion.min.js"></script>

    Main options:

    L.motion.polyline([], options, motionOptions, markerOptions).addTo(map); //  as L.polyline
    L.motion.polygon([], options, motionOptions, markerOptions).addTo(map); //  as L.polygon[], options).addTo(map); //  as L.featureGroup - to run all animation at same time
    L.motion.seq([], options).addTo(map); //  as L.featureGroup - to setup seq for animations.


    You can pass a number of options to the plugin to control various settings.

    Default control options

    Option Type Default Description
    pane Pane 'polymotionPane' Default pane

    Motion options

    Option Type Default Description
    auto Boolean false Indicates auto start animation when motion object added to the map
    easing L.Motion.Ease L.Motion.Ease.linear Animation strategy
    speed Number 0 Motion speed in KM/H
    duration Number 0 Motion duration in ms, 0 means no animation, instant rendering on motionStart()

    Marker options

    All MarkerOptions that you can add to any marker + one more:

    Option Type Default Description
    removeOnEnd Boolean false Removes marker from map on motion end
    showMarker Boolean false Add marker to the map on first line point when motion just added(start can be delayed) to the map

    Here's an example of passing through some options:

    L.motion.polyline([[50,0], [60,10]], {
    	color: "transparent"
    }, {
    	auto: true,
    	duration: 3000,
    	easing: L.Motion.Ease.easeInOutQuart
    }, {
    	removeOnEnd: true,
    	showMarker: true,
    	icon: L.divIcon({html: "<i class='fa fa-car fa-2x' aria-hidden='true'></i>", iconSize: L.point(27.5, 24)})

    To rotate the marker you need to properly setup motion-base angle on 90* north, so that it can be rotated to the movement direction.

    L.motion.polyline([{"lat":50,"lng":0},{"lat":51.15611417450841,"lng":-2.1906730905175213}], {
    }, null, {
    	removeOnEnd: true,
    	icon: L.divIcon({html: "<i class='fa fa-plane fa-2x' aria-hidden='true' motion-base='-48'></i>", iconSize: L.point(19, 24)})

    Public methods


    Public methods in all motion objects:

    motionStart() // to start motion.
    motionStop() // to stop motion.
    motionPause() // to pause motion.
    motionResume() // to resume paused motion.
    motionToggle() // to pause motion, if it's running. To start motion if it's not. Or just resume.
    getMarkers() // to get multi-dimensional array of markers from all motion sub components.

    L.motion.polyline and L.motion.polygon

    Additional methods in polyline and polygon

    // - expected duration for motion in milliseconds, can be used after motion is created to start animation
    // and can be used during animation to change object animation duration.
    // - expected motion speed in KM/H, can be used after motion is created to start animation
    // and can be used during animation to change object speed.
    addLatLng(latLng) // - allows to add additional point in the end for the motion animation.
     // Returns marker (if markerOptions is passed on creation) to attach needed behavior.
     // Marker will be added to the map only during animation


    addLayer(layer, autostart) // to append layer to the end of sequence and autostart it if needed

    Now we can add new layers to Seq object.

    • If it's not started yet, new layers will be added and prepared to start.
    • If it's running right now new layer will be added and wait it turn.
    • If it's completed, and you want to run new layer right now, additional parameter should be passed.
    var planePolyline = L.motion.polyline(planeRoute).motionDuration(2000);
    // Build the Sequence Group:
    var seqGroup = L.motion.seq([
    	trackPolyline, shipPolyline
    seqGroup.addLayer(planePolyline, true);

    Motion Events

    Event Value Description
    L.Motion.Event.Started { layer } Fires on motion stated on root element only
    L.Motion.Event.Paused { layer } Fires on motion paused on root element only
    L.Motion.Event.Resumed { layer } Fires on motion resumed on root element only
    L.Motion.Event.Ended { layer } Fires on motion ended on root element only
    L.Motion.Event.Section { layer } Fires on each motion section change in L.Motion.Seq starting with first one


    Please include next leaflet modules to make it work properly, or just whole Leaflet.js :)



    npm i leaflet.motion
