usage

npm install maplibre-gl-temporal-control

const map = new maplibregl.Map(mapOptions)

// anyLayer is maplibre layer-object
map.addLayer(anyLayer1_1)
map.addLayer(anyLayer1_2)
map.addLayer(anyLayer2_1)
map.addLayer(anyLayer2_2)
map.addLayer(anyLayer3_1)
map.addLayer(anyLayer3_2)
// some layers...

import TemporalControl from 'maplibre-gl-temporal-control';

const temporalFrames = [
    {
        title:'frame1', // shown on control panel
        layers:[anyLayer1_1, anyLayer1_2] // set layers you want to show at one frame...
    },
        title:'frame2',
        layers:[anyLayer2_1, anyLayer2_2]
    },
    {
        title:'frame3',
        layers:[anyLayer3_1, anyLayer3_2]
    },
    // add frames...
]

const temporalControl = new TemporalControl(temporalFrames, {
    interval: 100, // duration a frame is shown, in miliseconds
    position: 'top-left',
    performance: true // set when rendering is too slow, but frames which are not current are shown mostly transparent
});
map.addControl(temporalControl);

Tips

• In frames, You must set layer-objects corresponding to in map.
• Layers set in frames must be added in map
• when performance: true, not-current frames are shown as opacity=0.000000000000000000001
  • this option may not be neccesary for ordinary usecases
