Title

Fix CblReactNativeEngine to Correctly Implement ICoreEngine Interface

Summary

The current expo-example app fails to build due to CblReactNativeEngine not fully implementing the ICoreEngine interface. This mismatch causes compilation errors when attempting to run the example.

Changes

  • Updated CblReactNativeEngine implementation to align with the ICoreEngine interface contract.
  • Ensured all required methods are implemented with correct signatures.
  • Verified build completes successfully for the expo-example app.

Impact

  • Restores build functionality for the expo-example app.
  • Improves developer experience by ensuring example runs out-of-the-box.

Testing

  • Built and ran the expo-example app locally with no compilation errors.
  • Confirmed all interface methods compile and execute as expected.

Summary of Changes

Hello @idulo, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

I've addressed a critical build issue in the expo-example app by updating the CblReactNativeEngine to correctly implement the ICoreEngine interface. This involved adding placeholder methods for URLEndpointListener functionalities to satisfy the interface contract, ensuring the example application can now build successfully.

Highlights

  • Interface Implementation: I've updated the CblReactNativeEngine.tsx file to ensure it fully implements the ICoreEngine interface. This change is crucial for resolving build failures encountered in the expo-example application.
  • New Method Stubs: To satisfy the ICoreEngine interface, I've added several new methods related to URLEndpointListener functionality, such as _createListener, _startListener, _stopListener, _getStatus, and _deleteIdentity. These methods currently serve as placeholders, throwing 'Method not implemented' errors.
  • Dependency Updates: I've imported necessary types like URLEndpointListenerArgs, URLEndpointListenerCreateArgs, URLEndpointListenerStatus, and URLEndpointListenerTLSIdentityArgs from core-types to support the newly added interface methods.

Code Review

This pull request successfully addresses the build failure in the expo-example app by implementing the missing methods from the ICoreEngine interface in CblReactNativeEngine. The approach of adding stub implementations is appropriate for this goal. My feedback includes a suggestion to make the error messages in these new stub methods more specific, which will improve debuggability if they are ever called before being fully implemented.

While adding these stub methods correctly implements the ICoreEngine interface and fixes the build, the generic error message 'Method not implemented.' can be difficult to debug. It's better to provide a more specific error message for each method to clearly indicate which function was called but is not implemented. This will help developers who might try to use this functionality in the future.
