View Source Tesla.Middleware.JSON (tesla v1.7.0)

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
