Codeship Status for elixir-waffle/waffle Version waffle documentation

Waffle is a flexible file upload library for Elixir with straightforward integrations for Amazon S3 and ImageMagick.



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

defp deps do
    waffle: "~> 0.0.4",

    # If using Amazon S3:
    ex_aws: "~> 2.0",
    ex_aws_s3: "~> 2.0",
    hackney: "~> 1.6",
    poison: "~> 3.1",
    sweet_xml: "~> 0.6"

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


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 Amazon s3
  asset_host: "" # or {:system, "ASSET_HOST"}

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)
