Encode requests and decode responses as JSON.

This middleware requires Jason (or other engine) as dependency.

Remember to add {:jason, ">= 1.0"} to dependencies. Also, you need to recompile Tesla after adding :jason dependency:

mix deps.clean tesla
mix deps.compile tesla

Examples

defmodule MyClient do
  use Tesla

  plug Tesla.Middleware.JSON # use jason engine
  # or
  plug Tesla.Middleware.JSON, engine: JSX, engine_opts: [strict: [:comments]]
  # or
  plug Tesla.Middleware.JSON, engine: Poison, engine_opts: [keys: :atoms]
  # or
  plug Tesla.Middleware.JSON, decode: &JSX.decode/1, encode: &JSX.encode/1
end
