npm package for transport system

Installation

npm install @ph-itdev/ph-transport

Usage

import { calculateDistance, calculateETA, formatDistance } from '@ph-itdev/ph-transport';

// Calculate distance between two coordinates
const distance = calculateDistance(14.5995, 120.9842, 10.3157, 123.8854);
console.log(formatDistance(distance)); // "570.5 km"
