facebook/relay v1.5.0

on GitHub

This release introduces several changes, some of the most relevant ones are highlighted here.

New:

• Relay Containers are now Flow typed, however Flow types are not yet exported (#2284).
• Relay Compiler now generates Flow types for GraphQL enum values.
• Add undocumented support for client-only schema extensions using .graphql files. Extensions only work on existing types, and does not currently support adding client-only types to the schema.
• Add experimental and undocumented support for QueryRenderer to render directly from store if data is available using new dataFrom prop.
• Add hooks to enable and disable Relay GC in the store.
• New ConcreteNode format supporting Batch requests.

Potentially Breaking:

• Support for client-only schema extensions requires that your GraphQL schema not be inside your the directory you specify as src to the relay-compiler (#2346).
• Changes the type of RelayNetwork.execute to return a RelayObservable with variables and node, in addition to the QueryPayload. However, RelayNetwork.create maintains the same API (c058ffc).

Fixed:

• Fix passing a single item to a "list" input argument (42c1119).
• Fix end cursor when fetch returned zero edges in Pagination Container (a17b462).
• No longer throw false alarm error in RelayConcreteVariables (0398585).
• Properly handle complex GraphQL argument literals in the compiler (bb02769).
• Calling viewer handler multiple times should not accidentally cause viewer to be null (f442fcd).
• Fix issue when using multiple connectionInfo for RANGE_ADD mutation (7f2013d).
• Fix issue in Relay Compiler when parsing non-null input (4baa970).
• Fix pagination on empty connections (62c8b43).

Improved:

• Ensure the Relay build has run and is not using outdated GraphQL fragments. Optionally this can be turned off in the babel plugin settings (a628637).
• Update all callers of react-relay to use CommonJS requires.
• Speed up getIdentifierForSelection.
• Compiler doesn't warn on missing fields with abstract types anymore.
• Relay Compiler now de-duplicates identical objects when generating JSON artifacts which decreases size of artifacts and improves compressability.
• Disable NoFragmentCyclesRule; can now use Fragments recursively.
• Remove RecordSourceInspector which is of marginal value, especially now that we have a useful devtools app.
• Print timing information in compiler —verbose mode.
• Add option to Compiler to be —quiet.
• Upgrade to graphql-js v0.13.0.
• Upgrade to latest version of fast-glob.
• Upgrade to babylon7 in Relay Compiler to support new JSX Fragment syntax.
• Remove graphql.experimental.
• Several Flow typing improvements.
• Several documentation fixes.
• Move test utils to their own package: relay-test-utils.
• Add support for accessing Components wrapped in a Container in tests.
• Use jest snapshots for relay-compiler tests.
