Installation

If available in Hex, the package can be installed as:

1. Add google_maps to your list of dependencies in mix.exs:

def deps do
  [{:google_maps, "~> 0.9"}]
end

2. Ensure google_maps is started before your application:

def application do
  [applications: [:google_maps]]
end

3. In your application's config/config.exs, add:

config :google_maps,
  api_key: "YOUR API KEY HERE"

Or you can use GOOGLE_MAPS_API_KEY system environment variable when running in iex.

If separate API keys are needed per request, they can be set through key option, i.e.:

GoogleMaps.directions("Toronto", "Montreal", key: API_KEY_1)

Development

You'll need a Google API key with all relevant APIs (see above) enabled. Add your key to the environment as specified above.

Then run tests:

mix deps.get test

mix test
