Release Notes

jsdom/jsdom (jsdom)

v28.0.0

Compare Source

  • Overhauled resource loading customization. See the new README for details on the new API.
  • Added MIME type sniffing to <iframe> and <frame> loads.
  • Regression: WebSockets are no longer correctly throttled to one connection per origin. This is a result of the bug at nodejs/undici#4743.
  • Fixed decoding of the query components of <a> and <area> elements in non-UTF-8 documents.
  • Fixed XMLHttpRequest fetches and WebSocket upgrade requests to be interceptable by the new customizable resource loading. (Except synchronous XMLHttpRequests.)
  • Fixed the referrer of a document to be set correctly when redirects are involved; it is now the initiating page, not the last hop in the redirect chain.
  • Fixed correctness bugs when passing ArrayBuffers or typed arrays to various APIs, where they would not correctly snapshot the data.
  • Fixed require("url").parse() deprecation warning when using WebSockets.
  • Fixed <iframe>, <frame>, and <img> (when canvas is installed) to fire load events, not error events, on non-OK HTTP responses.
  • Fixed many small issues in XMLHttpRequest.
