qibla v1.1.0

The 'qibla' Library

A helper class (Qibla) to provide you the qibla direction relative to True North based on provided coordinates

Installation

Install using the Node Package Manager (NPM).

$ npm install qibla

OR

$ npm install qibla --save

Usage

Import the Qibla class. Call the static function degreesFromTrueNorth() with the coordinates of the current location (lat, long). It returns the direction of Kaaba from the current location i.e. the Qibla as degrees from True North.

TypeScript

import {Qibla} from 'qibla';

// Returns 280 for Mumbai
let qiblaFromTrueNorth = Qibla.degreesFromTrueNorth(19.0826881, 72.6009796);

JavaScript

let Qibla = require('qibla').Qibla;

// Returns 280 for Mumbai
let qiblaFromTrueNorth = Qibla.degreesFromTrueNorth(19.0826881, 72.6009796);

What angle is the Qibla from True North?

The qibla angle returned represents the angle shown in a typical smartphone compass app. i.e. *North = 0 deg*, *East = 90 deg*, *South = 180 deg*, and *West = 270 deg*

It should be noted that the actual angle shown in a physical (non digital, non smartphone) magnetic compass would be different because it references the Magnetic North. Smartphone compasses do not have such a problem as they automatically compensate and show the angles with respect to the True North.
