[Temporal](https://temporal.io)'s [TypeScript SDK](https://docs.temporal.io/typescript/introduction) interceptors for tracing Workflow and Activity executions with [OpenTelemetry](https://opentelemetry.io/) v2.

This package targets OpenTelemetry JS SDK v2. For OpenTelemetry JS SDK v1, use [`@temporalio/interceptors-opentelemetry`](https://www.npmjs.com/package/@temporalio/interceptors-opentelemetry).

**Warning** This package produces incompatible histories from `@temporalio/interceptors-opentelemetry`. Attempting to replay a workflow that was initially run with the original package can trigger a non-determinism error.
