Release Notes

jsdom/jsdom (jsdom)

v30.1.3

Compare Source

• Improved performance of getComputedStyle() and computed CSS property reads, including with stylesheets containing attribute selectors. (@​scttcper, @​asamuzaK)
• Fixed slowdowns when focusing elements and running interaction tests, which regressed in v30.1.2. (@​scttcper)
• Fixed XMLHttpRequest reusing credentials supplied to xhr.open() after cross-origin redirects, including in response to authentication challenges from the destination.
• Fixed XMLHttpRequest incorrectly sending and accepting cookies after cross-origin redirects back to the document's origin when xhr.withCredentials is false.

• Fixed getComputedStyle() ignoring style rules nested inside multiple @media rules.
• Fixed CSS shorthands overwriting longhands with higher priority or specificity during style computation, including declarations containing CSS variables.
• Fixed getComputedStyle() returning unresolved or inconsistent shorthand values, including for 'background', 'border', 'flex', 'font', 'margin', and 'padding', and incorrect shorthand defaults and inheritance.
• Fixed computed background positions to resolve font-relative lengths using the final font size and handle multiple image layers correctly.
• Fixed computed 'color' values depending on property read order, including unresolved color-mix() results, which regressed in v29.0.2.
• Fixed currentcolor border colors incorrectly becoming transparent when 'color' uses light-dark() or relative color syntax.
• Fixed CSS calculations that reduce to a percentage incorrectly producing pixel values, which regressed in v30.0.0.
• Fixed numeric font weights in the 'font' shorthand incorrectly setting 'line-height'.
• Fixed selector matching involving XML namespaces, and selectors such as [data-a|=""] failing to match empty values and values beginning with -. (@​asamuzaK)

Compare Source

• 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 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 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

Compare Source

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.

• 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 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 attr.ownerDocument after setting an attribute node on an element in another document or adopting its element. (@​Kjubikstronk)

• Fixed element.tagName returning stale casing after adoption between HTML and XML documents.
