react-relay v9.0.0 Release Notes

Release Date: 2020-02-13 // about 4 years ago

  • 9.0.0

    💥 Breaking

    • 📇 Rename getModernOperationVariables to getOperationVariables

    ➕ Added

    • ➕ Added queuePendingOperation to RelaModernMockEnvironment in testing tools. This allows the caller to manually register an operation that should be pending.
    • Optionally output eager es modules (#2781).
    • 🔦 Expose a way to override isGeneratedFile function via language plugin (#2810).
    • 👍 Allow language plugin to specify how generated files should be named (#2866).
    • 👍 Allow language plugin to specify how to check for presence of graphql strings (#2811).
    • Setup external config for Relay Compiler.

    🛠 Fixed

    • Ensure root record is always created upon store initialization, even before initial query has been processed.
    • 🛠 Fix disposable of optimistic updates: 87ef4ed
    • 🛠 Fix various issues in docs.
    • 🛠 Fix loading external config for Relay Compiler (#2999).

    Misc

    • DataChecker::check now returns the operation fetch time.
    • ✂ Removed getRelayDefaultMissingFieldHandlers.js

    Experimental

    • 🛠 Fix leaking environments when using Relay Hooks (#3014).
    • 🛠 Fix support of Fast Refresh when used with Relay Hooks.
    • 🛠 Fix recycling data for plural fragments; i.e. return an array with the sam object identity if the data hasn’t changed.
    • ➕ Add support for batched @stream’ed responses.
    • Internally renamed useLegacyPaginationFragment to usePaginationFragment.
    • Potentially Breaking
      • preloadQuery will error if called during render.
      • Remove new connection model experimental code.
      • We know check for “active” instead of queries in “flight” when determining when to suspend. An operation may be indefinitely in flight (e.g. a live query, or a GraphQL Subscription), but it’s only “active” if it’s actively receiving payloads, e.g. during @streaming or @defer.
