Google Distance Matrix API Library for Elixir

This library allows you to obtain the distance and travel times between multiple origins and destinations via various travel methods.

Installation

First, add distance_api_matrix to your mix.exs dependencies:

def deps do
  [{:distance_api_matrix, "~> 2.0"}]
end

and run $ mix deps.get.

Usage

# Create a travel_list with coords and/or addresses
iex> travels = DistanceMatrixApi.TravelList.new |>
  DistanceMatrixApi.TravelList.add_entry(%{origin: "Caen", destination: "Paris"}) |>
  DistanceMatrixApi.TravelList.add_entry(%{origin: "21 Rue de la République, 69002 Lyon, France", destination: "60 Rue de Rivoli, 75004 Paris, France"}) |>
  DistanceMatrixApi.TravelList.add_entry(%{origin: %{lat: 45.764043, long: 4.835658999999964}, destination: %{lat: 48.856614, long: 2.3522219000000177}})

# Basic call
iex> travels |> DistanceMatrixApi.distances

#with custom options
iex> options = %{mode: "bicycling", units: "imperial", language: "en-US"}
iex> travels |> DistanceMatrixApi.distances(options)
