Features

BREAKING CHANGES

• Removes the extend-expect script. Users should use
  the default import path or one of the new test platform-specific
  paths to automatically extend the appropriate "expect" instance.

extend-expect was not documented in the Readme, so this change should
have minimal impact.

Users can now use the following import paths to automatically extend
"expect" for their chosen test platform:

• @​testing-library/jest-dom - jest (@​types/jest)
• @​testing-library/jest-dom/jest-globals - @​jest/globals
• @​testing-library/jest-dom/vitest - vitest

For example:

import '@​testing-library/jest-dom/jest-globals'

Importing from one of the above paths will augment the appropriate
matcher interface for the given test platform, assuming the import
is done in a .ts file that is included in the user's tsconfig.json.

It's also (still) possible to import the matchers directly without
side effects:

import * as matchers from '@​testing-library/jest-dom/matchers'

• Update kcd-scripts
• Drop node < 14

jsdom is feeling the AGI!

This release is dedicated to @​scttcper, who unleashed @​codex upon jsdom and found tons of performance improvements. Along the way, he found and fixed many correctness issues as well.

We really appreciate his thoughtful PRs, which did a great job following the project's contribution guidelines, and were clearly human-curated, with their PR descriptions edited to be brief and respectful of the maintainers' time.

Thanks to @​scttcper, as well as all the other contributors of this release (most of whom were AI-assisted).

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.

• 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.

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.

v27.4.0

Compare Source

• Added TextEncoder and TextDecoder.
• Improved decoding of HTML bytes by using the new @exodus/bytes package; it is now much more correct. (@​ChALkeR)
• Improved decoding of XML bytes to use UTF-8 more often, instead of sniffing for <meta charset> or using the parent frame's encoding.
• Fixed a memory leak when Ranges were used and then the elements referred to by those ranges were removed.

v27.3.0

Compare Source

• Improved CSS parsing and CSSOM object APIs via updates to @acemir/cssom. (@​acemir)

v27.2.0

Compare Source

• Added CSSGroupingRule, CSSNestedDeclarations, CSSConditionRule, CSSContainerRule, CSSScopeRule, CSSSupportsRule, CSSLayerBlockRule, and CSSLayerStatementRule to jsdom Windows. (@​acemir)
• Improved CSS parsing and CSSOM object APIs via updates to @acemir/cssom. (@​acemir)
• Fixed @import-ed stylesheets to be properly exposed to CSSOM, and not to overwrite the sheet created from the <link> or <style> element. (@​acemir)

v27.1.0

Compare Source

• Improved CSS parsing by switching to @acemir/cssom, including support for nested selectors, nested declarations, layer statements, and improved at-rule validation. (@​acemir)
• Fixed some selector cache invalidation issues where changes to attributes were not being picked up. (@​asamuzaK)
• Fixed package.json "engines" field to reflect the new minimum Node.js versions needed to run jsdom, as noted in the changelog for v27.0.1.

v27.0.1

Compare Source

This release inadvertently raised the minimum Node.js version from v20.0.0 to v20.19.0+, v22.12.0+, v24.0.0+. (This happened via a dependency update.) This probably should have been a breaking (major) change, instead of happening in a patch version, since it prevents using earlier Node.js versions.

After further testing, we found that most of our development dependencies also require these versions, and so it's not feasible for the jsdom project to support earlier Node.js versions. (For example, our testing frameworks will not run on them.) If you need to use such earlier versions, or otherwise are working in an environment which gives related errors such as ERR_REQUIRE_ESM, then please stick with the v26.1.0 release of jsdom. (Noting, of course, that such versions are unsupported, and we will not respond to bug reports opened against them.)

Subsequent jsdom releases will explicitly require these minimum Node.js versions, and will have CI testing to ensure that the minimum version is not accidentally raised again.

Normal changelog:

• Fixed some regressions in CSS selectors. Most such regression fixes were done in a minor update of a dependency, and thus available for all fresh installs of v27.0.0. However, one related to class="" attribute changes is only possible with a new version of jsdom. (@​asamuzaK)

v27.0.0

Compare Source

Changes since 26.1.0

• Node.js v20 is now the minimum supported version.
• Added a variety of event constructors, even though we do not implement their associated specifications or ever fire them: BeforeUnloadEvent, BlobEvent, DeviceMotionEvent (omitting requestPermission()), DeviceOrientationEvent (omitting requestPermission()), PointerEvent, PromiseRejectionEvent, and TransitionEvent.
• Added movementX and movementY to MouseEvent. (These are from the Pointer Lock specification, the rest of which is not implemented.)
• Added customElements.getName(). (@​mash-graz)
• Updated the virtual console:
  • "jsdomError" events are now documented, with specific type properties and other properties that depend on the type.
  • sendTo() was renamed to forwardTo().
  • The jsdomErrors option to forwardTo() can be used to control which errors are sent to the Node.js console. This replaces the previous omitJSDOMErrors boolean option.
  • "jsdomError"s for failed XMLHttpRequest fetches are no longer emitted.
  • The values that are printed when forwarding "jsdomError"s to the Node.js console are streamlined.
• Switched our CSS selector engine from nwsapi to @asamuzakjp/dom-selector, closing over 20 selector-related bugs.
• Upgraded tough-cookie, which now considers URLs like http://localhost/ to be secure contexts (per the spec), and thus will return Secure-flagged cookies for such URLs. (@​colincasey)
• Upgraded cssstyle, which brings along many improvements and fixes to the CSSStyleDeclaration object and its properties.
• Updated the user agent stylesheet to be derived from the HTML Standard, instead of from an old revision of Chromium.
• Changed element.click() to fire a PointerEvent instead of a MouseEvent.
• Changed certain events to be passive by default.
• Changed the <input> element's pattern="" attribute to use the v regular expression flag, instead of u.
• Fixed many specification conformance issues with the Window object, including named properties and changing various data properties to accessor properties.
• Fixed document.createEvent() to accept a more correct set of event names.
• Fixed the ElementInternals accessibility getters and setters. (They were introduced in v23.1.0, but due to inadequate test coverage never actually worked.)
• Fixed using Object.defineProperty() on certain objects, such as HTMLSelectElement instances.
• Fixed jsdom.reconfigure({ url }) not updating document.baseURI or properties derived from it. (This regressed in v26.1.0.)
• Fixed CSS system colors, as well as the initial, inherit, and unset keywords, to resolve correctly. (@​asamuzaK)
• Fixed CSS display style resolution. (@​asamuzaK)

Changes since 27.0.0-beta.3

• Upgraded cssstyle, which brings along various CSS parsing fixes.

• Added SVGAnimatedPreserveAspectRatio and SVGAnimatedRect, including support in the reflection layer.
• Added the SVGSVGElement createSVGRect() method, and the SVGRect type (which is distinct from DOMRect.)
• Added indexed property support to HTMLFormElement.
• Updated the SVGElement viewportElement() method to correctly establish the viewport based on ancestor elements.
• Removed the now-bloated form-data dependency in favor of our own smaller implementation of multipart/form-data serialization. No functional changes are expected.
• Various performance improvements, caches, microoptimizations, and deferred object creation.

• Updated whatwg-url, adding support for URL.parse().
• Updated cssstyle and rrweb-cssom, to improve CSS parsing capabilities.
• Updated nwsapi, improving CSS selector matching.
• Updated parse5, fixing a bug around <noframes> elements and HTML entity decoding.
• Fixed JSDOM.fromURL() to properly reject the returned promise if the server redirects to an invalid URL, instead of causing an uncaught exception.

• Updated dependencies, notably tough-cookie, which no longer prints a deprecation warning.

v25.0.0

Compare Source

This major release changes the prototype of a jsdom's EventTarget.prototype to point to the Object.prototype inside the jsdom, instead of pointing to the Node.js Object.prototype. Thus, the prototype chain of Window stays entirely within the jsdom, never crossing over into the Node.js realm.

This only occurs when runScripts is set to non-default values of "dangerously" or "outside-only", as with the default value, there is no separate Object.prototype inside the jsdom.

This will likely not impact many programs, but could cause some changes in instanceof behavior, and so out of an abundance of caution, we're releasing it as a new major version.

v24.1.3

Compare Source

• Fixed calls to postMessage() that were done as a bare property (i.e., postMessage() instead of window.postMessage()).

v24.1.2

Compare Source

• Fixed an issue with the in operator applied to EventTarget methods, e.g. 'addEventListener' in window, which only appeared in Node.js ≥22.5.0. (@​legendecas)
• Fixed the events fired by blur(): it no longer fires focus and focusin on the Document, and blur and focusout no longer have their relatedTarget property set. (@​asamuzaK)

v24.1.1

Compare Source

• Fixed selection methods to trigger the selectionchange event on the Document object. (@​piotr-oles)

v24.1.0

Compare Source

• Added the getSetCookie() method to the Headers class. (@​ushiboy)
• Fixed the creation and parsing of elements with names from Object.prototype, like "constructor" or "toString".
• Updated rweb-cssom, which can now parse additional CSS constructs.

v24.0.0
