Geocoder ![Build Status]( [![Inline docs](]( [![Coverage Status](](

A simple, efficient geocoder/reverse geocoder with a built-in cache.

Is it extensible? Yes.
**Is it any good?** Absolutely.


Keep calm and add Geocoder to your `mix.exs` dependencies:

def deps do
  [{:geocoder, "~> 1.1"}]

Update your mix dependencies:

mix deps.get

If you are Elixir < 1.9, you'll need to use a version before `1.0`.


All configuration below is optional. Sane defaults are set so you don't need to think too hard.

Set pool configuration:

config :geocoder, :worker_pool_config, size: 4, max_overflow: 2

Set provider configuration:

config :geocoder, :worker,
  # OpenStreetMaps or OpenCageData are other supported providers
  provider: Geocoder.Providers.GoogleMaps,
  key: System.get_env("GEOCODER_GOOGLE_API_KEY")

Note that `OpenStreetMaps` (the default provider) is the only provider that does not require an API key to operate.
All other providers require an API key that you'll need to provide.

If you need to set a proxy (or any other option supported by HTTPoison.get/3):

config :geocoder, Geocoder.Worker, [
  httpoison_options: [proxy: "my.proxy.server:3128", proxy_auth: {"username", "password"}]

Let's rumble!


{:ok, coordinates } ="Toronto, ON")
{:ok, coordinates } ={43.653226, -79.383184})


You can pass options to the function that will be passed to the geocoder provider, for example:

```elixir "Toronto, ON", language: "es", key: "...", ...)

You can also change the provider on a per-call basis:

{:ok, coordinates } =
    # use the default provider
    {:error, nil} <-,
    # use an alternative provider. If `key` is not specified here the globally defined key will be used.
    {:error, nil} <-, provider: Geocoder.Providers.OpenCageData, key: "123"),
    do: {:error}

See [here]( and [here]( for a list of supported parameters for the google maps geocoder provider (`Geocoder.Provider.GoogleMaps`).

And you're done! How simple was that?


Right now, `geocoder` supports three providers (i.e. sources):

* `Geocoder.Providers.GoogleMaps`
* `Geocoder.Providers.OpenCageData`
* `Geocoder.Providers.OpenStreetMaps`

To run the tests for these, and any future providers, you'll want to pass a `PROVIDER` environment variable:

PROVIDER=google mix test

By default, the tests run on OpenStreetMaps.
