Absinthe.Middleware.Async (absinthe v1.6.4) View Source

This plugin enables asynchronous execution of a field.

See also Absinthe.Resolution.Helpers.async/1

Example Usage:

Using the Absinthe.Resolution.Helpers.async/1 helper function:

field :time_consuming, :thing do
  resolve fn _, _, _ ->
    async(fn ->
      {:ok, long_time_consuming_function()}
    end)
  end
end

Using the bare plugin API

field :time_consuming, :thing do
  resolve fn _, _, _ ->
    task = Task.async(fn ->
      {:ok, long_time_consuming_function()}
    end)
    {:middleware, Elixir.Absinthe.Middleware.Async, task}
  end
end

This module also serves as an example for how to build middleware that uses the resolution callbacks.

See the source code and associated comments for further details.
