Elixir plugin: proper way to get form data from post request

I'm playing around with inserting a router and trying to read the body of a simple post request in the router :

sheet

<form action="/create_item" method="post">
  <input type="text" value="whatever" name="name">
  <input type="number" value="99" name="age">
  <input type="submit">
</form>

my router

post("/create_item") do
  {:ok, data, _conn} = read_body(conn)
  send_resp(conn, 200, data)
end

If I submit the form it renders name=input-valueto the page, but then I have to parse the string to get the value. This smells the wrong way.

From my little experience with elixir, it seems like I should be doing something like pattern matching on read_body(conn)to extract each key: valuefrom the form , but I can't find anything about this in the plug docs . I'm trying to dig out some ideas from Phoenix Resources, but it's beyond my knowledge of elixirs. Am I missing an obvious function?parse_form_data/1
