Base Usage

const map = L.map('map', {preferCanvas: true}).setView([51.505, -0.09], 13);
L.tileLayer('https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png').addTo(map);

L.canvasMarker(L.latLng(51.495, -0.06), {
    radius: 20,
    img: {
        url: 'icon.png',    //image link
        size: [40, 40],     //image size ( default [40, 40] )
        rotate: 10,         //image base rotate ( default 0 )
        offset: { x: 0, y: 0 }, //image offset ( default { x: 0, y: 0 } )
    },
}).addTo(map);

Direction Arrow

You can specify the previous point (prevLatlng: latlng). The picture will automatically show the direction of movement.

const map = L.map('map', {preferCanvas: true}).setView([51.505, -0.09], 13);
L.tileLayer('https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png').addTo(map);

L.canvasMarker(L.latLng(51.495, -0.06), {
    radius: 20,
    prevLatlng: L.latLng(51.503, -0.09),    //previous point
    img: {
        url: 'arrow.png',
        size: [40, 40],
        rotate: 0,
    },
}).addTo(map);
