Haversinejs

Javascript Haversine Distance Calculator

Installation

Use the package manager npm to install haversinecalc.

npm i haversinecalc

Usage

const {Point, haversine} = require("haversinecalc")

const src_p = new Point(-7,7) // source (lat,lon)
const dst_p = new Point(-8,8) // destinantion (lat,lon)

haversine(src_p, dst_p, is_miles) // is_miles bool

// Multiple count
// ==============
const {haversines} = require("haversinecalc")

let src1 = {
   lat: 7,
   lon: 7
}

let src2 = {
   lat:6,
   lon:6
}

let dst = {
   lat: 5,
   lon: 5
}

let points = [
   {
      src: src1,
      dst,
      is_miles: false
   },
   {
      src: src2,
      dst,
      is_miles: false
   }
]
console.log(haversines(points))
