Zipkin HTTP Transport

This package, `zipkin-transport-http`, provides the official HTTP transport mechanism for sending Zipkin trace data to a Zipkin collector server. It is a core component within the larger `zipkin-js` ecosystem, designed to integrate seamlessly with other `zipkin-js` packages like `zipkin` (for `BatchRecorder`) and various instrumentation libraries. The current stable version is `0.22.0`, released recently with improvements like a fallback for `fetch` and fixes. The project maintains a fairly active release cadence, frequently addressing bugs, adding new features such as configurable `fetch` API and SQS support in related packages, and improving TypeScript interfaces. Its primary differentiator is its deep integration and official support within the OpenZipkin JavaScript tracing suite, ensuring compatibility and alignment with Zipkin's tracing specifications.
