Minne

Multipart form parser for plug based applications that allows customizing the file handling behaviour. To be used as a replacement for the built in :multipart handler.

Installation

If available in Hex, the package can be installed by adding minne to your list of dependencies in mix.exs:

def deps do
  [
    {:minne, "~> 0.1.0"}
  ]
end

Usage

Tweak your Plug.Parsers config to include Minne

S3

Requires ExAws.S3 and its dependencies.

Will upload the file to S3 directly, never hitting the servers hardrive.

plug(Plug.Parsers,
  parsers: [
    {
      Minne,
      adapter: Minne.Adapter.S3
      adapter_opts: [bucket: "some-bucket", upload_prefix: "upload"],
    },
    :urlencoded,
    :json
  ],
  json_decoder: Jason
)

Temp

This behaves almost identically to the built in Plug.Upload, and writes the files to temp.

plug(Plug.Parsers,
  parsers: [
    {
      Minne,
      adapter: Minne.Adapter.Temp
    },
    :urlencoded,
    :json
  ],
  json_decoder: Jason
)

From the Controller

The built-in Plug.Parsers.MULTIPART represents files parsed from the body as a Plug.Upload struct. Minne does similar, but is instead a Minne.Upload, it is not a drop in replacment for Plug.Upload, but would not be hard to adapt code to use it.
