the latest version of
graphql-json 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-jsmight setup jest/ts-jest: simply add the custom exports conditionsdevelopment(while retainingnode) via the jest config testEnvironmentOptions / customExportConditionsCompare with earlier attempts for the previously proposed esm-only #8082 and #8083 which requires babel or swc => retaining the dual build simplifies these changes.
