v0.14.3

Patch Changes

• 🐞🩹 large non-blocking DOM operation batches now yield the main thread every ~40ms, keeping tasks under the 50ms long-task threshold and reducing reported TBT (by @gioboa in #756)

• ✨ automatically execute partytown scripts added to the page after initialization, e.g. on client-side route transitions, without needing to dispatch a ptupdate event (by @gioboa in #746)

• ✨ GTM's Tag Assistant preview now connects to pages running GTM inside Partytown: scripts the worker can't read (no CORS headers, like the debug bootstrap) fall back to the main thread, the container's debug queue is bridged during gtm_debug sessions, and window.opener / message event.source work from the worker (by @gioboa in #753)

• ✨ CSP Trusted Types support: Partytown now works on pages enforcing require-trusted-types-for 'script' — add partytown to the trusted-types directive to allow its policy (by @gioboa in #754)

• 🐞🩹 load cross-origin iframes natively when their content can't be fetched, so widgets like the reCAPTCHA badge work instead of crashing with a NetworkError (by @gioboa in #749)

• 🐞🩹 partytown scripts added after the main thread fallback ran, e.g. gtm.js injected by the GTM snippet, now fall back too — previously they were silently dropped in webviews without service worker support (by @gioboa in #751)

• 🐞🩹 ship partytown-sandbox-sw.html as a real library file, so requests that bypass the service worker (crawlers, private browsing, encoded urls) get a 200 instead of a 404 (by @gioboa in #750)

• 🐞🩹 methods called unbound by scripts (e.g. var f = win.fn; f()) no longer crash the worker proxy, fixing Google Publisher Tag ad serving (by @gioboa in #755)

v0.14.2

Patch Changes

• 🧹 remove the unused dotenv dependency, the package has zero runtime dependencies again (by @gioboa in #742)

• ✨ fallbackTimeout: 0 disables the main thread fallback entirely (by @gioboa in #741)

• 🐞🩹 don't throw when the snippet runs in an iframe with a cross-origin top, run Partytown in the iframe itself instead (by @gioboa in #735)

• 🐞🩹 support document.createRange().createContextualFragment() and document.fonts (load/check/ready) in the worker (by @gioboa in #731)

• 🐞🩹 the main thread fallback now loads external scripts through their src, previously only inline content was copied (by @gioboa in #739)

• 🐞🩹 keep forwarded globals (e.g. dataLayer) local to the worker instead of sync-proxying them to the main thread, forward items already pushed before Partytown loads, and stop dropping forwarded events when the worker global doesn't exist yet (by @gioboa in #721)

• 🐞🩹 don't crash initialization when a Proxy global (e.g. vinxi's MANIFEST) returns unclonable objects during the window snapshot (by @gioboa in #737)

• 🐞🩹 run navigator.sendBeacon and iframe contentWindow.fetch urls through resolveUrl, so analytics requests like GA4's /g/collect can be proxied (by @gioboa in #740)

• 🐞🩹 allocate the atomics SharedArrayBuffer small and grow it on demand instead of eagerly reserving 1GB, which newer Chrome versions can refuse (by @gioboa in #729)

• 🐞🩹 add a noindex robots meta to the sandbox html so crawlers stop reporting 404s for it in Search Console (by @gioboa in #738)

• 🐞🩹 stop rewriting this inside string literals, template literal text and comments when preparing scripts for the worker (by @gioboa in #730)

• 🐞🩹 serialize underscore-prefixed object members for the worker (e.g. wp.i18n.__), excluding only partytown internals (by @gioboa in #736)

• 🐞🩹 only treat digit property names as window frame indexes, so globals like Infinity resolve correctly in the worker (by @gioboa in #732)

v0.14.1

Patch Changes

• 🐞🩹 don't throw when a script assigns an invalid value to a.href, e.g. http:// (by @gioboa in #725)

• 🐞🩹 allow resolveUrl to return a Readonly<URL> (by @gioboa in #726)

• 🐞🩹 match <script> tags case-insensitively when rewriting iframe srcdoc HTML, so <SCRIPT> variants can't bypass the rewrite (by @gioboa in #724)

• 🐞🩹 wrap the snippet in an IIFE so top-level helpers no longer leak t, e, n into the page's global scope and break other classic scripts (by @gioboa in #727)

v0.14.0

Minor Changes

• ✨ add logForwardedEvents config flag to enable debug logging for forwarded events and triggers (by @mws19901118 in #704)

Patch Changes

• 🐞🩹 initialise ErrorObject to Error instead of null to prevent instanceof crash (by @gioboa in #714)

v0.13.2

Patch Changes

• 🐞🩹 update repository metadata to QwikDev/partytown and bump Node to 24.x for OIDC trusted publishing (by @thejackshelton in 1b34fe1)

v0.11.2

Patch Changes

• ✨ Implement full attribute methods for HTMLImageElement (by @mws19901118 in #681)
