## AI overview

Sentry describes an effort to replace monkey-patching in server-side JavaScript APM tools with Node's TracingChannel API. The approach lets libraries publish structured events that observability tools can consume without patching, loader hooks, or strict initialization ordering, with stated support across Node, Bun, and Deno.

## Source excerpt

Sentry is adding TracingChannel support to 44 JavaScript libraries upstream, replacing fragile monkey-patching with native observability that works across all runtimes.
