Relay v21.0

· 37 min read
The Relay Team

Relay v21.0.0 brings first-party TypeScript support, modernized Flow type generation, new error handling capabilities, and experimental React Server Components support. This release contains several breaking changes -- please read the migration notes below carefully.

Upgrading​

TypeScript users: First-party .d.ts type definitions are now shipped directly in relay-runtime and react-relay. You no longer need @types/relay-runtime from DefinitelyTyped. Node.js ESM named imports (e.g. import { fetchQuery } from 'relay-runtime') now work correctly in .mjs files. Thank you to everyone who contributed to the DefinitelyTyped type definitions over the years — your work kept the Relay TypeScript community going, and it served as a valuable reference for these first-party types.

Flow users -- action required: Generated types now use modern Flow syntax. (expr: Type) casts are replaced with (expr as Type) (requires Flow >= 0.250.0), $ReadOnlyArray becomes ReadonlyArray, mixed becomes unknown, and $NonMaybeType becomes NonNullable. After upgrading, you must re-run the Relay compiler to regenerate all artifacts.

@live_query removed: The @live_query directive has been removed. Migrate to @client_polling(interval: ...) for polling behavior, or @live for server-pushed updates.

Relay Resolvers -- new syntax required: The enable_legacy_verbose_resolver_syntax flag has been removed. The legacy verbose docblock syntax (@onType, @onInterface, @fieldName, @edgeTo) no longer works. In addition, we've replaced the generic @RelayResolver tag with more specific @relayField and @relayType tags. The Relay compiler can automatically migrate you to this new syntax via the relay-compiler codemod fix-all command. If you're not ready to migrate, you can enable the allow_legacy_relay_resolver_tag feature flag in your compiler config file.

@oneOf inputs: @oneOf input types now generate a stricter discriminated union type that only permits one property at a time, instead of an object with all optional fields. This catches bugs at compile time where multiple fields were incorrectly set simultaneously. You can opt out via oneOfType: "relaxed" in compiler config if needed.

New Features​

@catch expansion: @catch now works on @connection fields and client edge fields, letting you gracefully handle field errors in pagination and client-edge scenarios instead of throwing.

@alias on fragment definitions: The @alias directive now works on fragment definitions (not just inline fragments).

New compiler CLI tools: Two experimental subcommands are available: experimental-regenerate-sub-schema replaces the currently configured schema file with the portion of the provided "full schema" and experimental-compare-document-ir compares intermediate representations (IR) of documents passed and outputs selections that exists in left but not in right.

React Server Components (Experimental): A new react-relay/rsc_EXPERIMENTAL entry point provides an experimental API for fetching GraphQL in server components: serverFetchQuery for server-side data fetching, serverReadFragment for reading fragment data on the server, and serverPreloadQuery + useQueryFromServer for preloading data on the server and hydrating the client store. These APIs are experimental and are likely to change in upcoming versions.

Notable Bug Fixes​

  • Large schema crash fixed: A stack overflow when printing schemas with very large types (1000+ fields) has been fixed with iterative drop logic.
  • @raw_response_type accuracy: Selections on abstract types in @raw_response_type are now correctly typed as optional when the concrete type may not implement the abstract type (PR #4775).
  • Conflicting @match fields: The compiler now properly validates and reports errors for conflicting @match fields across fragments, preventing silent runtime issues.
  • Watch mode stability: Numerous incremental compilation fixes improve reliability of --watch mode, including cross-project fragment crash resolution and proper detection of schema field changes.
