A leaflet control that indicates tile loading progress for a group of tile layers

Package Exports

  • leaflet-tile-loading-progress-control

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (leaflet-tile-loading-progress-control) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

leaflet-tile-loading-progress-control

A leaflet control that indicates tile loading progress for a group of tile layers. This can be useful when you have a lot of tile layers or tiles that frequently refresh.

NPM

My particualar use case was for a looping precipitation radar that was built using ten tile layers that each needed to be updated every five minutes. Zooming and panning the map causes a lot of tile requests to be sent out. These can take a second to load and in the meantime I didn't want the end user to think the map was breaking.

Usage

import 'leaflet-tile-loading-progress-control';
import 'leaflet-tile-loading-progress-control/dist/Control.TileLoadingProgress.css';

const tileLayer1 = L.tileLayer('https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png')
const tileLayer2 = L.tileLayer('http://tile.stamen.com/toner/{z}/{x}/{y}.png');

const tileLayers = L.layerGroup([tileLayer1, tileLayer2]);

const tileLoadingProgress = new L.Control.TileLoadingProgress({
    leafletElt: tileLayers,
    position: 'bottomleft'
});
tileLoadingProgress.addTo(map);

Options

Option Type Description
leafletElt Leaflet LayerGroup Group of tile layers tracked by the loading progress control.
