# 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
todo
## Usage
# Basic call
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"]}
response = DistanceMatrixApi.get_distances(addresses_params)
# Call with coordinates
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}]}
response = DistanceMatrixApi.get_distances_by_coords(coords_params)
# With custom options
options_params = %{mode: "bicycling", units: "imperial", language: "en-US"}
response = DistanceMatrixApi.get_distances(addresses_params, options_params)
## Options
All options defined in the [Google distance matrix documentation](https://developers.google.com/maps/documentation/distance-matrix/intro) are available, such as: `mode` `key` `language` `units` etc.
## Todo
- Set default options
- Handle rate limiting
- Handle max encoded url length
- Add some more guards on options
- Add custom functions to fetch results and map them
