Installation

Add the latest stable release to your mix.exs file, along with the required dependencies for ExAws if appropriate:

defp deps do
  [
    {:waffle, "~> 1.0.1"},

    # If using S3:
    {:ex_aws, "~> 2.1"},
    {:ex_aws_s3, "~> 2.0"},
    {:hackney, "~> 1.9"},
    {:sweet_xml, "~> 0.6"}
  ]
end

Then run mix deps.get in your shell to fetch the dependencies.

Configuration

Waffle expects certain properties to be configured at the application level:

config :waffle,
  storage: Waffle.Storage.S3, # or Waffle.Storage.Local
  bucket: {:system, "AWS_S3_BUCKET"}, # if using S3
  asset_host: "http://static.example.com" # or {:system, "ASSET_HOST"}

# If using S3:
config :ex_aws,
  json_codec: Jason

Along with any configuration necessary for ExAws.

Usage with Ecto

Waffle comes with a companion package for use with Ecto. If you intend to use Waffle with Ecto, it is highly recommended you also add the waffle_ecto dependency. Benefits include:

• Changeset integration
• Versioned urls for cache busting (.../thumb.png?v=63601457477)
