It is a ridiculous behavior.\n\n`await rl.question()` throws `AbortError` and messes up your terminal:\n\n```\n$ node ./test.mjs\nnode:internal/readline/interface:1331\n            this[kQuestionReject]?.(new AbortError('Aborted with Ctrl+C'));\n                                    ^\n\nAbortError: Aborted with Ctrl+C\n    at [_ttyWrite] (node:internal/readline/interface:1331:37)\n    at ReadStream.onkeypress (node:internal/readline/interface:284:20)\n    at ReadStream.emit (node:events:508:28)\n    at emitKeys (node:internal/readline/utils:371:14)\n    at emitKeys.next (\u003canonymous\u003e)\n    at ReadStream.onData (node:internal/readline/emitKeypressEvents:64:36)\n    at ReadStream.emit (node:events:508:28)\n    at addChunk (node:internal/streams/readable:559:12)\n    at readableAddChunkPushByteMode (node:internal/streams/readable:510:3)\n    at Readable.push (node:internal/streams/readable:390:5) {\n  code: 'ABORT_ERR'\n}\n```\n\nIt is not sophisticated.\n\n### What is the feature you are proposing to solve the problem?\n\nAdd an option to `creatInterface` to prevent it from trapping `SIGINT` by default.\n\n```js\nconst rl = createInterface({ input: stdin, output: stderr, noTrapSigInt: true });\n```\n\nWith this, you will be able to press Ctrl + C to terminate the program immediately with the proper exit code.\n\n### What alternatives have you considered?\n\n```js\nimport { platform } from \"node:process\";\n\nrl.on(\"SIGINT\", () =\u003e {\n  process.exit(platform === \"win32\" ? -1073741510 : 130);\n});\n```\n\nWhy do I have to add such a code? Who the hell can remember such numbers for both platforms?","author":{"url":"https://github.com/tats-u","@type":"Person","name":"tats-u"},"datePublished":"2026-01-23T06:53:01.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":9},"url":"https://github.com/61487/node/issues/61487"}
