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.

It is for now an early version of the library and many features are to come :)

Installation

First, add distance_api_matrix to your mix.exs dependencies:

def deps do
  [{:distance_api_matrix, "~> 1.0"}]
end

and run $ mix deps.get.

Usage

# Basic call
iex> addresses_params = %{origins: ["842-844 Rossville Ave, Staten Island, NY, State of New York 10309, United states", "Paris"],
                     destinations: ["847-899 Coolidge Ave, Woodbridge, NJ 07095, United states", "Lyon"]}

iex> DistanceMatrixApi.get_distances(addresses_params)

# Call with coordinates
iex> coords_params = %{destinations: [%{lat: 45.764043, long: 4.835658999999964}, %{lat: 48.856614, long: 2.3522219000000177}],
                  origins: [%{lat: 48.856614, long: 2.3522219000000177}, %{lat: 45.764043, long: 4.835658999999964}]}

iex>  DistanceMatrixApi.get_distances_by_coords(coords_params)

# With custom options
iex> options_params = %{mode: "bicycling", units: "imperial", language: "en-US"}

iex>  DistanceMatrixApi.get_distances(addresses_params, options_params)
