Plug v0.12.1 → Overview → Plug → MIME

Plug.MIME

Maps MIME types to file extensions and vice versa.

MIME types can be extended in your application configuration as follows:

config :plug, :mimes, %{
  "application/vnd.api+json" => ["json-api"]
}

After adding the configuration, Plug needs to be recompiled. If you are using mix, it can be done with:

$ touch deps/plug/mix.exs
$ mix deps.compile plug
Source
