graphql v1.7.0 Release Notes

  • 💥 Breaking changes

    • GraphQL::Result is the returned from GraphQL execution. #898 Schema#execute and Query#result both return a GraphQL::Result. It implements Hash-like methods to preserve compatibility.

    🆕 New features

    • 🖨 puts ctx.backtrace prints out a GraphQL backtrace table #946
    • GraphQL::Backtrace.enable wraps unhandled errors with GraphQL backtraces #946
    • GraphQL::Relay::ConnectionType.bidrectional_pagination = true turns on true bi-directional pagination checks for hasNextPage/hasPreviousPage fields. This will become the default behavior in a future version. #960
    • Field arguments may be accessed as methods on the args object. This is an alternative to #[] syntax which provides did-you-mean behavior instead of returning nil on a typo. #924 For example:
      # using hash syntax:
  args[:limit]    # => 10
  args[:limittt]  # => nil
  # using method syntax:
  args.limit      # => 10
  args.limittt    # => NoMethodError

    The old syntax is not deprecated.

    • 👌 Improvements to schema filters #919

      • If a type is not referenced by anything, it's hidden
      • If a type is an abstract type, but has no visible members, it's hidden

    • 🏗 GraphQL::Argument.define builds re-usable arguments #948

    • GraphQL::Subscriptions provides hooks for subscription platforms #672

    • GraphQL::Subscriptions::ActionCableSubscriptions implements subscriptions over ActionCable #672

    • More runtime values are accessble from a ctx object #923 :

      • ctx.parent returns the ctx from the parent field
      • ctx.object returns the current obj for that field
      • ctx.value returns the resolved GraphQL value for that field

    These can be used together, for example, ctx.parent.object to get the parent object.

    • 🐎 GraphQL::Tracing provides more hooks into gem internals for performance monitoring #917
    • GraphQL::Result provides access to the original query and context after executing a query #898

    🐛 Bug fixes

    • Prevent passing both query string and parsed document to Schema#execute #957
    • Prevent invalid names for types #947
