Worklets 0.9.1

Key changes

Support for cross-runtime Promises

Now functions that return a promise like runOnRuntimeAsync can be used on all runtimes in Bundle Mode, not only the RN Runtime. The code responsible for memory-management of JavaScript callbacks in C++ was overhauled to support this, which should reduce the memory imprint and stability of long-held callbacks in brownfield app.

• feat(Worklets): cross-runtime promise handling in Bundle Mode by @tjzel in https://github.com/software-mansion/react-native-reanimated/pull/9451
• refactor(Worklets): remoteFunction memory model by @tjzel in https://github.com/software-mansion/react-native-reanimated/pull/9272

Uniform Shareable hosting

Shareables can now be hosted on any runtime, not only the UI Runtime.

• Added shareable support outside UI runtime by @tshmieldev in https://github.com/software-mansion/react-native-reanimated/pull/9391

DX improvements

• Passing a local function to scheduleOnRN no longer crashes the app in C++ but throws an actionable error in JavaScript.
• feat(Worklets): actionable error when passing local function to scheduleOnRN by @tjzel in https://github.com/software-mansion/react-native-reanimated/pull/9386

• We append an asynchronous stacktrace to error thrown in Worklets for easier debugging.

This is an opt-out feature that can be disabled with ENABLE_CROSS_RUNTIME_STACK_TRACES static feature flag.

• Add RN runtime error traces to errors from UI runtime by @tshmieldev in https://github.com/software-mansion/react-native-reanimated/pull/9280

• Console implementation in Bundle Mode now prints objects exactly the same way on Worklet Runtimes as on the RN Runtime.
• Added native logging behavior to worklets runtime by @tshmieldev in https://github.com/software-mansion/react-native-reanimated/pull/9201
