on-the-edge

Deno edge functions for anitrend-v2 to offload data aggregation out of the main application.

Testing utilities

See docs/testing-utilities.md for Deno-native helpers (stubFetch, onGet/onPost, setEnvScoped) to write deterministic, offline tests.

Series: episodes docs

See docs/series/episodes-pipeline.md for a high-level overview of the episodes endpoint pipeline and modules.

Observability (OTEL)

OpenTelemetry initialization is now lazy and opt-in to avoid side effects during unit tests.

• Runtime: OTEL is initialized in createState() via init() from src/common/core/otel.ts. This happens when the server boots (see src/common/core/setup.ts).
• Tests: Importing modules will not auto-start OTEL; tests run without initializing the SDK. Shutdown remains available via shutdown() for runtime signals.
• Configuration: Set the following env variables to enable exporters. If a given endpoint is omitted, that exporter is skipped.
  • OTEL_DENO_SERVICE_NAME (service name)
  • DENO_VERSION (service version)
  • DENO_ENV (deployment environment)
  • OTEL_EXPORTER_OTLP_TRACES_ENDPOINT
  • OTEL_EXPORTER_OTLP_METRICS_ENDPOINT
  • OTEL_EXPORTER_OTLP_LOGS_ENDPOINT

To disable observability entirely, omit the OTLP endpoint variables.
