Release Notes

jsdom/jsdom (jsdom)

v30.1.2

Compare Source

• Updated URLs to support Unicode v18.0.0 in internationalized domain names.
• Reduced package size and memory use for CSS property definitions. (@​scttcper)
• Fixed severe slowdowns when building large DOM trees, including SVG charts with D3, which regressed in v30.1.0. (@​cmdcolin)
• Fixed exponentially slow reads of empty inherited CSS custom properties in deeply nested documents, and custom properties incorrectly inheriting past an initial reset. (@​scttcper)
• Fixed getComputedStyle() returning stale results after editing stylesheet declarations, selectors, or media queries, including in imported stylesheets.
• Fixed selector matching and computed styles after changes to form control checkedness, indeterminacy, selection, values, and validity, including during form resets and canceled clicks.
• Fixed computed styles for :focus, :focus-visible, :focus-within, and selectors containing them after focus changes, including inside focus and blur listeners. (@​asamuzaK)
• Fixed element.focus() incorrectly focusing elements hidden by 'display', including through shadow hosts and slots, and elements excluded by shadow DOM slot assignment. (@​asamuzaK)
• Fixed getComputedStyle() throwing for elements without inline-style support, including XML and MathML elements.
• Fixed a memory leak where stylesheet parsing retained the last parsed stylesheet's window after window.close().
• Fixed memory growth from long-lived MutationObserver instances retaining bookkeeping for garbage-collected nodes. (@​scttcper)
• Fixed retained select.selectedOptions collections becoming stale after selection changes and form resets.
• Fixed rejection of negative CSS sizing values, including for 'min-width', 'min-height', 'max-width', and 'max-height', which regressed in v30.1.0.

v30.1.1

Compare Source

• Fixed spurious window blur and focusout events and incorrect event.relatedTarget values when focusing an element after removing the previously focused element, which regressed in v30.1.0. (@​asamuzaK)
• Fixed focus and blur behavior across frames, and focusing the document's viewport through document.documentElement.focus(). (@​asamuzaK)
• Fixed focus targets removed or disabled by blur listeners becoming active, and text selections made by focus and blur listeners being overwritten. (@​asamuzaK)
• Fixed element.focus() incorrectly focusing disabled form controls and <input type="hidden"> elements with tabindex="". (@​scttcper)
• Fixed invalid style.setProperty() calls changing existing !important priorities, serialized styles, or mutation records. (@​FedgeNo)
• Fixed !important handling when updating CSS longhands after shorthands, using variables or CSS-wide keywords, and assigning style properties directly. (@​FedgeNo)
• Fixed <noscript> parsing with includeNodeLocations: true or inside frames to honor the runScripts option.
• Fixed the storageQuota option being ignored by frames.
• Fixed encoding detection of HTML and XML byte input to honor XML encoding declarations and detect UTF-16 without a byte order mark.
• Fixed exceptions caused by truncated charset parameters in <meta> elements, and encoding detection incorrectly using incomplete <meta> tags. (@​FedgeNo)
• Fixed XML serialization errors for namespaces named constructor, toString, __proto__, or "null", and incorrect reuse of namespace prefixes declared on sibling elements.
• Fixed element.innerHTML and element.outerHTML in XML documents to reject invalid characters in attribute values and avoid stack overflows on large strings.
• Fixed selector matching for :lang(), :nth-child(... of ...) after mutations, and :has() with duplicate IDs or nested logical pseudo-classes. (@​asamuzaK)

v30.1.0

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).

• Added named access to elements on document, such as document.myForm for <form name="myForm">. (@​vojtisprime11)
• Added QuotaExceededError, including its use for storage quota errors and oversized crypto.getRandomValues() requests.
• Added support for the relaxed DOM naming rules when creating elements, attributes, and document types.
• Improved performance of DOM construction, tree mutations, range operations, and live collection access, especially on large documents. (@​scttcper, @​erezrokah)
• Improved performance of getComputedStyle(), style changes, and CSS serialization. (@​scttcper, @​jhult)
• Improved performance of event dispatch, form control and label lookups, and updates to <select> elements and radio button groups. (@​scttcper)
• Reduced memory use when creating and working with DOM nodes, attributes, event listeners, and mutation observers. (@​scttcper)
• Changed window.close() to preserve access to the document and its DOM through retained references.
• Fixed element.querySelectorAll() returning no matches when the first part of the selector matches the element itself, which regressed in v30.0.0. (@​asamuzaK)
• Fixed case sensitivity in CSS attribute selectors, including selectors matching data-state="", title="", and other case-sensitive values. (@​asamuzaK)
• Fixed document.querySelector() failing to find a matching element when an earlier element has the same ID but does not match the rest of the selector. (@​vojtisprime11)
• Fixed :focus matching in shadow trees. (@​asamuzaK)
• Fixed DOM insertion and replacement, including valid document.replaceChildren() calls, invalid document element and doctype placements, and mutations during element.replaceWith().
• Fixed the ordering of script execution, custom element callbacks, iframe loading, and mutation observer notifications during DOM insertion, including in shadow trees.
• Fixed queued events and navigation continuing after window.close() or iframe removal, and prevented new scripts, resource loads, timers, and animation frames from starting in destroyed documents. (@​scttcper)
• Fixed parent documents waiting indefinitely for loading to finish when a child iframe removes itself during loading.
• Fixed request cancellation across redirects, during pending requestInterceptor() callbacks, and when reusing an XMLHttpRequest after aborting it.
• Fixed resource loading and JSDOM.fromURL() potentially hanging when response handling throws and response stream cleanup does not finish.
• Fixed successful cached resource loads being treated as aborted.
• Fixed getComputedStyle() and document.styleSheets using the wrong stylesheet order after inserting or updating <style> elements.
• Fixed getComputedStyle() ignoring nested @import and @media rules in imported stylesheets, and returning stale results after imports finish loading.
• Fixed style invalidation, stylesheet removal, and frame source updates in shadow trees.
• Fixed repeated getComputedStyle() calls changing case-sensitive background URLs, and inconsistent resolution of border shorthands containing system colors. (@​scttcper)
• Fixed computed border widths, including borderless elements incorrectly reporting 16px, which regressed in v30.0.0. (@​Alberto-BaseNet)
• Fixed getComputedStyle() to resolve 'font-weight' keywords to numeric values. (@​tianrking)
• Fixed getComputedStyle() to convert lengths to pixels inside CSS math functions containing percentages, and to resolve percentages in 'font-size' math functions. (@​soroushm)
• Fixed serialization of min() and max() containing nested calc(), which regressed in v30.0.0. (@​asamuzaK)
• Fixed CSS values mixing lengths or percentages with math functions, such as 'grid-template-columns' values containing both 100px and calc(). (@​rome-xi)
• Fixed parsing of 'background' and 'border' shorthands with adjacent components, such as url(a.png)no-repeat, including a crash when parsing inline styles. Also fixed handling of invalid shorthand assignments and escaped or unusual characters in CSS declarations. (@​asamuzaK)
• Fixed parsing of unitless zero values in 'flex' shorthands, such as 35 1 0, and rejection of negative 'flex-basis' lengths and percentages. (@​asamuzaK)
• Fixed shorthand style assignments producing extra mutation records and custom element callbacks for intermediate values. (@​scttcper)
• Fixed Range and Selection handling of CDATA sections, including boundary offsets and range cloning, extraction, deletion, insertion, and stringification. (@​scttcper)
• Fixed text.normalize() incorrectly removing the text node or merging its siblings. (@​scttcper)
• Fixed cloning and importing CDATA sections and processing instructions whose contents have been modified, and serialization of CDATA sections adopted into HTML documents.
• Fixed stale named-property collections on window, and incorrect named access from empty or namespaced id="" and name="" values. (@​scttcper)
• Fixed elements in documents created with DOMParser or document.implementation.createHTMLDocument() appearing as named properties on window and being retained in memory. (@​Iaotle)
• Fixed memory leaks from mutation observers retaining observed nodes, abort signals retaining removed event listeners, and storage event tracking retaining closed windows. (@​scttcper)
• Fixed storage events being sent to windows created after the storage change, and ensured surviving recipients still receive events when the source document is destroyed.
• Fixed attribute lookups after namespace prefix changes, and namespaced attributes incorrectly affecting ID lookups and element behavior. (@​scttcper)
• Fixed input.list in detached element trees. (@​scttcper)
• Fixed attr.ownerDocument after setting an attribute node on an element in another document or adopting its element. (@​Kjubikstronk)
• Fixed fresh element.getElementsByTagName() calls using the previous document's case-sensitivity rules after adoption between HTML and XML documents. (@​Kjubikstronk)
• Fixed element.tagName returning stale casing after adoption between HTML and XML documents.
• Fixed radio button grouping and checkedness updates for controls with different form owners, controls outside their form, unnamed controls, and canceled clicks.
• Fixed <select> selection updates when moving options, and unintended selection resets when moving a whole <select> or changing unrelated descendants.
• Fixed cloning <input> elements to preserve input.indeterminate.
• Fixed focus state after removing a focused element or its ancestor, including inside shadow trees.
• Fixed script execution when inserting children into a connected, empty <script>. (@​Kjubikstronk)
• Fixed incorrect script execution after changes to src="", and handling of type="", for="", and event="".
• Fixed document.currentScript during nested script execution and scripts in shadow trees.
• Fixed event dispatch, window.event, and default passive listener handling for non-node event targets, and event dispatch when user code modifies window.constructor.
• Fixed volumechange and ratechange events to fire asynchronously. (@​christianaurichzm)
• Fixed DOM APIs accepting user-created proxies around DOM objects where genuine DOM objects are required.
• Fixed XPath iterator invalidation after DOM mutations and errors for invalid result types.

Library Tests fails at tsc -b on lib/vitest.argos.config.ts (BrowserProviderOption<PlaywrightProviderOptions> not assignable to BrowserProviderOption<object>). The lockfile now resolves vitest 5.0.5 twice: lib, website and vscode-ext keep the variant whose auto-installed jsdom peer is 29.1.1, while @vitest/browser and @vitest/browser-playwright were moved to the jsdom 30.1.3 variant. lib's config therefore mixes types from two vitest copies. Library Tests is green on main at f585b915e, so this split is what turns it red.

No package declares jsdom@^29 anymore, so the fix is to collapse onto jsdom 30.1.3 (what pnpm dedupe would do): point the three importers' vitest at the jsdom 30 variant, and drop the jsdom 29 vitest snapshot, jsdom@29.1.1, and the packages only it reached. That moves lib/website/vscode-ext's jsdom-environment tests to jsdom 30, which CI will exercise. I'll push that lockfile change to this branch.
