TypeScript Telemetry v3.0.0-alpha.0

on GitHub

Breaking Changes

• Constructor now requires projectSlug as second argument
• capture() no longer takes path/projectId — takes tags/metadata/sessionId/userId instead
• Removed opinionated span methods (span.completion(), span.tool(), etc.) — use telemetry.tracer directly
• Removed rosetta-ai dependency
• Env var renamed from GATEWAY_BASE_URL to LATITUDE_TELEMETRY_URL

Added

• telemetry.tracer exposes raw OTel Tracer for custom span creation
• capture() creates a root span when no active span exists, grouping child spans under one trace
• serviceName option in constructor
• RedactSpanProcessor for masking sensitive HTTP headers
• Auto-instrumentation for 10 AI providers via Traceloop

Changed

• capture() sets trace-wide baggage (latitude.tags, latitude.metadata, session.id, user.id) propagated via BaggageSpanProcessor
• Span processors passed via NodeTracerProvider constructor (not deprecated addSpanProcessor)
