v13.1.0

Misc

• [0ad48b3] removes old aliases in generated files by default. This can be restored temporarily with the compiler config "flowTypegen": "Compat" but projects should migrate to using the updated names (e.g. MyFragment$fragmentType instead of MyFragment$ref.

Full Changelog: v13.0.0...v13.0.1

v13.0.0

Breaking Changes

• relay-compiler is now implemented in Rust and it replaced the JS version from v12.
  • The motivation and details for this change are captured here: https://relay.dev/blog/2021/12/08/introducing-the-new-relay-compiler/
  • A few new features that are supported in the new compiler:
    • TypeScript code generation added to the compiler.
    • New directives:
      • @required: Improve the ergonomics of handling null values by declaratively telling Relay to either LOG, THROW, or bubble (NONE) null fields.
      • @no_inline: Disable inlining the fragment when it is used in normalization(query) artifacts. Reduce generated artifacts size if the fragment is used in many places.
    • Support for generic query persisting in the configuration.
  • Breaking changes in the new Relay compiler
    • No field aliases can start with two underscores; these are reserved for internal Relay use.
    • Export query hashes to JSON is removed.
  • The quick instructions on how to use the new compiler are here:
    • https://github.com/facebook/relay/blob/main/packages/relay-compiler/README.md
• Updates in runtime, React APIs, and generated flow types for better integration with Flow: and a first class support for types in flow for graphql tags. It may break some of the components that rely on the structure of the generated Relay flow-types.
• Statically flow-type the second parameter passed to updaters, optimistic updaters and commitLocalUpdate; it is now derived from the shape of the mutation and is optional. This type had previously been typed as $FlowFixMe (i.e. any); as a result, adding static types here is a breaking change.
• Removed relay-config.

v12.0.0

Relay Release Notes - 12.0.0

Commits: v11.0.2...main

About the Release

This is release contains a long list of new fixes and additions to Relay that was added in the last few months: runtime optimizations, react integration updates, logger updates, internal type-safety, documentation updates, and more.

It also contains a few small, but possibly, breaking changes. One of which is related to the Abstract Type Refinement, others to the live query behavior.

The Relay team is continuing work on the new rust-version of the compiler, and VS Code extension. As well as experimenting with the new features: multi-environment runtime support, advanced client-state management APIs. We hope to include these in the upcoming releases.

Thanks to all contributors for your work and support!

Breaking

• Relay Runtime: Promote type refinement to default feature (no flag). In OSS this flag was false by default, but true in internal configuration [2732db5].
• useQueryLoader will not cancel network requests, except for live queries [211d6fe].
• useLazyLoadQuery will not cancel network requests, except for live queries [a75da57].

Added

• Add Suspense logging to Relay Network Logger.
• Add log event for when QueryResource suspends.
• Add suspense logging when suspending from containers.
• Add log event for when FragmentResource suspends.
• Website: First draft of Relay Compiler Playground.
• React: Support double invoking effects in QueryRenderer.
• Runtime: Enabled unique subscription root: every response received is now processed in a unique Relay store root.
• Runtime: Enable batched store updates by default.
• Runtime: FragmentResource store revision optimization.
• Add Suspense logging to Relay Network Logger.
• Add execute.* events to the Relay Logger.
• Expose various hooks utils from relay-runtime: getPaginationMetadata, getPaginationVariables, getRefetchMetadata, getValueAtPath, type Direction [3b6f70d].

• Fix memory leak in containers [5a0c4c6].
• Fix Relay Dev Tools network events.
• Fix throwing promise from RelayModernFragmentSpecResolver.
• Add improved type safety to useSubscription API.
