title: convert snake_case keyed map to camelCase keyed map in elixir, phoenix before sending stuff as JSON
body: <p>I want to change keys of maps in elixir from snake case to camel case before sending stuff as JSON. How can I do that? Should it be just a function in which I will wrap every response or should it be done on some lower level, i.e. in Poison?</p>
  
  <p>Thanks</p>
