@uservane/langfuse-push: LangfuseScoreClient
Type Alias: LangfuseScoreClient
Section titled “Type Alias: LangfuseScoreClient”LangfuseScoreClient =
object
Defined in: index.ts:35
Minimal Langfuse surface we use (matches installed SDK; injectable for tests).
Methods
Section titled “Methods”flush()
Section titled “flush()”flush(
callback):void
Defined in: index.ts:56
Drain the ingestion queue and report the result via the callback. We use
flush(cb), NOT flushAsync(): verified against langfuse-core@3.38.20
(lib/index.mjs), flushAsync() SWALLOWS an ingestion HTTP failure
(logIngestionError + resolve, never rejects), so it cannot distinguish a
delivered score from a lost one. flush(cb) surfaces the final error (after
the SDK’s own fetch retries) as the callback’s err argument, which is the
only reliable delivery confirmation the SDK exposes.
