Requirements

  • I have added test coverage for new or changed functionality
  • I have followed the repository's pull request submission guidelines
  • I have validated my changes against all supported platform versions

Describe the solution you've provided

If present, environmentId is now passed to the HookRunner in the evaluation series.

For streaming connections:

  • Response headers are now attached to the open event (feat: report event source headers on open js-eventsource#33)
  • StreamingProcessor passes these headers to the stream listeners via processJson. The listener for the PUT event extracts the environmentId from the headers and passes this as initialization metadata to the underlying feature store.

For polling connections:

  • PollingProcessor retrieves the response headers via the underlying Requestor and extracts the environmentId from the headers and passes this as initialization metadata to the underlying feature store.

LDClient will then call getInitMetaData() on the underlying feature store (if the feature store supports it) when executing a hook and pass environmentId in the execution series data.

Currently only InMemoryFeatureStore has been modified to support initialization metadata. This functionality can be added to other feature stores by modifying init() to accept the optional initMetadata parameter and implementing the optional getInitMetadata() method.
