I realize that this technique has issues when trying to return json response via a websocket channel i.e.
For example, I have a channel with the following response
def handle_in("customers", %{}, socket) do
query = "SELECT json_agg(customers)::text FROM customers"
result = Repo.query!(query, [])
{:reply, {:ok, %{customers: result.rows}}, socket}
end
I think the reply gets encoded again. Hence, have to JSON.parse(payload.response.customers) on the client end.
Not sure if there is a way to control how the channel encodes the reply?
