Release Notes

jsdom/jsdom (jsdom)

v29.0.0

Compare Source

Breaking changes:

  • Node.js v22.13.0+ is now the minimum supported v22 version (was v22.12.0+).

Other changes:

  • Overhauled the CSSOM implementation, replacing the @acemir/cssom and cssstyle dependencies with fresh internal implementations built on webidl2js wrappers and the css-tree parser. Serialization, parsing, and API behavior is improved in various ways, especially around edge cases.
  • Added CSSCounterStyleRule and CSSNamespaceRule to jsdom Windows.
  • Added cssMediaRule.matches and cssSupportsRule.matches getters.
  • Added proper media query parsing in MediaList, using css-tree instead of naive comma-splitting. Invalid queries become "not all" per spec.
  • Added cssKeyframeRule.keyText getter/setter validation.
  • Added cssStyleRule.selectorText setter validation: invalid selectors are now rejected.
  • Added styleSheet.ownerNode, styleSheet.href, and styleSheet.title.
  • Added bad port blocking per the fetch specification, preventing fetches to commonly-abused ports.
  • Improved Document initialization performance by lazily initializing the CSS selector engine, avoiding ~0.5 ms of overhead per Document. (thypon)
  • Fixed a memory leak when stylesheets were removed from the document.
  • Fixed CSSStyleDeclaration modifications to properly trigger custom element reactions.
  • Fixed nested @media rule parsing.
  • Fixed CSSStyleSheet's "disallow modification" flag not being checked in all mutation methods.
  • Fixed XMLHttpRequest's response getter returning parsed JSON during the LOADING state instead of null.
  • Fixed getComputedStyle() crashing in XHTML documents when stylesheets contained at-rules such as @page or @font-face.
  • Fixed a potential hang in synchronous XMLHttpRequest caused by a race condition with the worker thread's idle timeout.
