Release Notes

jsdom/jsdom (jsdom)

v28.1.0

Compare Source

  • Added blob.text(), blob.arrayBuffer(), and blob.bytes() methods.
  • Improved getComputedStyle() to account for CSS specificity when multiple rules apply. (asamuzaK)
  • Improved synchronous XMLHttpRequest performance by using a persistent worker thread, avoiding ~400ms of setup overhead on every synchronous request after the first one.
  • Improved performance of node.getRootNode(), node.isConnected, and event.dispatchEvent() by caching the root node of document-connected trees.
  • Fixed getComputedStyle() to correctly handle !important priority. (asamuzaK)
  • Fixed document.getElementById() to return the first element in tree order when multiple elements share the same ID.
  • Fixed <svg> elements to no longer incorrectly proxy event handlers to the Window.
  • Fixed FileReader event timing and fileReader.result state to more closely follow the spec.
  • Fixed a potential hang when synchronous XMLHttpRequest encountered dispatch errors.
  • Fixed compatibility with environments where Node.js's built-in fetch() has been used before importing jsdom, by working around undici v6/v7 incompatibilities.

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.
