facebook/relay v21.0.0 on GitHub

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.
