Overlay day and night regions on a Leaflet Earth map.

Leaflet.Terminator extends the Polygon class. Adding the terminator to a leaflet map is as easy as

<script src="https://unpkg.com/leaflet"></script>
<script src="https://unpkg.com/@joergdietrich/leaflet.terminator"></script>

var map = L.map('map').addLayer(L.tileLayer('http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png'));
L.terminator().addTo(map)

Or with npm:

import L from 'leaflet';
import terminator from '@joergdietrich/leaflet.terminator';

var map = L.map('map').addLayer(L.tileLayer('http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png'))
terminator().addTo(map);

In addition to all Polygon options, Leaflet.Terminator has a new option "resolution", which gives the step size at which the terminator points are computed. The step size is 1°/resolution, i.e. higher resolution values have smaller step sizes and more points in the polygon. The default value is 2.
