Important Bits

Feb 2020 GraphQL Meetup Notes

February 23, 2020

This meetup

  • NodeJS dataloader library for batching DB queries, how to use dataloaders
  • Can Apollo generate warnings on deprecated fields? Maybe, need to learn more about schema directives.
  • One schema, one folder. No shared schema between different apps, choose isolation over DRY

    • What can be shared? Custom scalar types, an error type, a currency object
  • Separate errors into user errors from public errors (clarify the difference)
  • Testing graphql? Prefer integration tests to unit tests to see if your actual relationships are working. Mocking too many things gets you incorrect results.
  • Soo many libraries!
