Deno 2.8 wires
fetch(),node:http/node:httpsclient requests, andWebSocketinto the Chrome DevTools Network tab via the Network CDPdomain, but the debugging guide didn't mention any of this. This adds a
new "Inspecting network traffic" section to
runtime/fundamentals/debugging.mdthat explains how to attach DevTools with
--inspect-waitand what theNetwork tab now shows, with a small
fetch()example and a note thatthe instrumentation has no overhead when no debugger is attached.
Image references are included as placeholders to be filled in before
