Auto-batching data fetches for Skuld: Haxl-style query do-notation with dependency analysis and concurrent dispatch.

• Skuld.QueryContract — deffetch for batchable fetch contracts
• Skuld.Query.Contract — query contract protocol and wiring
• Skuld.Query.QueryBlock — dependency graph analysis and concurrent execution
• Skuld.Query.Cache — computation memoization

Installation

def deps do
  [
    {:skuld_query, "~> 0.32"}
  ]
end

Quick start

defmodule MyApp.Queries do
  use Skuld.QueryContract

  deffetch get_user(id :: String.t()) :: User.t() | nil
  deffetch get_orders(user_id :: String.t()) :: [Order.t()]
end

use Skuld.Query

defquery user_with_orders(id) do
  user <- MyApp.Queries.get_user(id)
  orders <- MyApp.Queries.get_orders(id)
  {user, orders}
end

See the architecture guide for how this fits into the Skuld ecosystem.
