docs: point response.set setHeader link at current Node.js docs#1995FirmaSpring wants to merge 1 commit into
Conversation
The previous target used the legacy anchor form and the /dist/latest/ snapshot path, while the current docs use /api/ with new-style anchors. The old anchor no longer matches the live page's section ids. Co-authored-by: FirmamentalSpring <287222957+FirmaSpring@users.noreply.github.com>

📝 WalkthroughWalkthroughThe response API documentation now uses the current Node.js Merge Risk: 🔵 Low · up to The updated link points readers to the request API section rather than the response API section, so the documentation may lead users to the wrong guidance. This is a localized, low-risk fix that should be corrected or explicitly accepted before merge. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

Node.js current HTTP API response.setHeader anchor
💡 Result:
In the Node.js HTTP API, the method response.setHeader(name, value) is used to set a single header value for implicit headers [1][2]. Regarding your interest in the "anchor," the official Node.js documentation uses the fragment identifier #response.setheadernname-value (often rendered as #response.setHeader in the table of contents or via direct linking) to provide a deep link to the response.setHeader() documentation section [3][2]. Key details about response.setHeader() include: * Functionality: It sets or updates a header in the to-be-sent headers [1][2]. If the header already exists, its value is replaced [1][2]. * Case Insensitivity: Header names are case-insensitive [3][4]. * Call Chaining: The method returns the response object itself, allowing for call chaining [1][2][5]. * Usage Constraints: Headers must be set before the response body is sent [6][7]. If response.writeHead() is called, headers set via response.setHeader() are merged with those passed to writeHead(), with writeHead() taking precedence [1][2]. * Data Types: While value can be a string, number, or array, non-string values are stored without modification but will be converted to strings for network transmission [1][2]. For the most accurate and current documentation, you can always refer to the official Node.js API reference at https://nodejs.org/api/http.html#responsesetheadername-value [3].

Link to the response API, not the request API.
Koa calls response.setHeader. Update the link to #responsesetheadername-value.

The link update change and summation are correct! 👍

Problem
docs/api/response.md(response.set) linkssetHeaderatThe page redirects to the current docs, but the fragment uses the legacy anchor id form. On the live page the section ids are the new style, so the browser cannot scroll to the
setHeadersection after the redirect (the old id only survives on the legacy snapshot pages).Solution
Link directly to the current docs page and its real anchor:
Verification
curl -sL https://nodejs.org/api/http.html | grep -c 'requestsetheadername-value'returns 1.http_request_setheader_name_valueis absent from the current/api/http.htmlpage (checked with grep).Summary by CodeRabbit
