cheerfulstoic / lib-my_app_web-graphql-middleware-relay_connection_lazy_evaluate.ex
Created November 16, 2020 09:40
Middleware for Elixir's `absinthe` to deal with efficient querying of `edges` and `totalCount`
defmodule MyAppWeb.Graphql.Middleware.RelayConnectionLazyEvaluate do
@moduledoc """
Absinthe requires all of the data for a connection to be loaded in the `resolve`
for the field. This means that regardless of if a client requests `edges` or
`totalCount`, the server needs to do one query for both every time.
This middleware evaluates the query that was done by the client to figure out
what fields were requested. It will only load the data which is required for
a typical connection based on what the client has requested
