# Shortest-route

Pass a list of cities in a pipe separated format and get the shortest route and the distance corresponding to that route. Shortest route means "shortest possible route that visits each city exactly once and returns to the origin city", so if you are goin to city A and then to city B and then to city C (your input will be A|B|C) then this module will give you the shortest route. For example if you are covering less kilometers between A to C then to B then your shortest route will be A|C|B|A (A to C to B then back to A). I used google distance matrix api to calculate the distance between cities.

## Explanation

Calculating the distance between cities provided using google distance matrix api and then calculating all the permutations and the distance of all the permutations. So if you have cities such as A,B and C then:-

```A-B B-C C-A (Distances by google matrix api)

ABC, ACB, BAC, BCA, CAB, CBA (all the permutations)

Distance for ABC = A-B-C-A (A to B to C to A)

finally calculate the distance of each permutation and whichever is the shortest one will be your shortest route.```

## Installation

`npm install shortest-route;`

## Quick Start

```var shortestRoute = require("shortest-route");
var cityList = "A|B|C"
shortestRoute.getShortPath(cityList, function(json){
console.log("data="+json);
});

Output:-

data = {
"STATUS":"SUCCESS",
"route":"A|C|B|A",
"distance":XXX
}

and in case of an Error (Most probably a bad request)
data={
"STATUS":400,
"route":null,
"distance":null
}```

## Demo

A simple demo http://short-route-demo.herokuapp.com/. Enter city names and get the shortest path and distance related to that path.
