Installation and use

npm i sun-position

import { SunPosition } from 'sun-postion';

const coords = {
    lat: -4.56454,
    lng: -38.9172
}
// June 22, 2023, at 5 pm, 52 minutes and 3 seconds
const date = new Date(2023, 5, 22, 17, 52, 3);

// Initialize object
const sunPosition = new SunPosition(
    // Latitude
    coords.lat,
    // Longitude
    coords.lng,
    // Date-time
    date
    );

// Update coordinates
// sunPosition.setLatitude(coords.lat);
// sunPosition.setLongitude(coords.lng);

// Update Date-time
// sunPosition.setDateTime(date);

// Capturing feedback from the Sun's elevation angle and azimuth
let elevation = await sunPosition.getElevation();
let azimuth = await sunPosition.getAzimuth();
