Usage

Since release 2.0.0, Leaflet.AutoGraticule is published as an ES module only. Install it using npm install -S leaflet-auto-graticule and use it in your code like so:

import AutoGraticule from "leaflet-auto-graticule";

new AutoGraticule().addTo(map);

TypeScript is supported.

If you want to use Leaflet.AutoGraticule directly inside a website without using a module bundler (not recommended for production), you need to make sure to import it and Leaflet as a module, for example from esm.sh:

<script type="importmap">
	{
		"imports": {
			"leaflet": "https://esm.sh/leaflet",
			"leaflet-auto-graticule": "https://esm.sh/leaflet-auto-graticule"
		}
	}
</script>
<script type="module">
	import L from "leaflet";
	import AutoGraticule from "leaflet-auto-graticule";

	const map = L.map('map', { center: [0, 0], zoom: 5 });
	L.tileLayer("https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png", {
		attribution: '© <a href="http://www.openstreetmap.org/copyright" target="_blank">OSM Contributors</a>',
		noWrap: true
	}).addTo(map);
	new AutoGraticule().addTo(map);
</script>

Options

const options = {
    /** Leaflet map event on which to redraw the graticule. */
    redraw: 'moveend',

    /** Minimum distance in pixels between two graticule lines. */
    minDistance: 100
};

new L.AutoGraticule(options).addTo(map);
