{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"The punycode deprecation trace is not useful","articleBody":"### Version\n\nv24.13.1\n\n### Platform\n\n```text\nDarwin \u003chostname\u003e 24.6.0 Darwin Kernel Version 24.6.0: Wed Nov  5 21:34:00 PST 2025; root:xnu-11417.140.69.705.2~1/RELEASE_ARM64_T8132 arm64\n```\n\n### Subsystem\n\n_No response_\n\n### What steps will reproduce the bug?\n\nIn a project that uses punycode _somewhere_.\n```\nNODE_OPTIONS='--trace-deprecation' npm t\n```\n\nor more concretely (although obviously in this case it's trivial to identify the source):\n```\nnpm init -y\nnpm i psl@1.8.0\nnode --trace-deprecation -e 'require(\"psl\")'\n```\n\n### How often does it reproduce? Is there a required condition?\n\nalways\n\n### What is the expected behavior? Why is that the expected behavior?\n\nI would expect a trace telling me which package/file is requiring punycode\n\n### What do you see instead?\n\nWhat I actually get is\n```\n(node:49440) [DEP0040] DeprecationWarning: The `punycode` module is deprecated. Please use a userland alternative instead.\n    at node:punycode:7:10\n    at BuiltinModule.compileForInternalLoader (node:internal/bootstrap/realm:398:7)\n    at BuiltinModule.compileForPublicLoader (node:internal/bootstrap/realm:337:10)\n    at loadBuiltinModule (node:internal/modules/helpers:125:7)\n    at loadBuiltinWithHooks (node:internal/modules/cjs/loader:1195:15)\n    at Module._load (node:internal/modules/cjs/loader:1285:48)\n    at TracingChannel.traceSync (node:diagnostics_channel:328:14)\n    at wrapModuleLoad (node:internal/modules/cjs/loader:245:24)\n    at Module.require (node:internal/modules/cjs/loader:1548:12)\n    at require (node:internal/modules/helpers:152:16)\n```\n\n### Additional information\n\nI note that https://github.com/nodejs/node/pull/56632 will reduce the number of times this warning appears, so perhaps that's good enough - but in general it seems reasonable to say that using `--trace-deprecation` should actually trace the usage of deprecated code.","author":{"url":"https://github.com/glenjamin","@type":"Person","name":"glenjamin"},"datePublished":"2026-02-20T12:23:55.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":9},"url":"https://github.com/61901/node/issues/61901"}
