the latest version of
graphql-js
on main is dual esm/cjs build with proper exports map.graphql/graphql-js#4464 adds development mode via custom condition
This PR demonstrates how a consumer of
graphql-js
might setup jest/ts-jest: simply add the custom exports conditionsdevelopment
(while retainingnode
