The latest news releases from the Qwik team

July 16th, 2026

@qwik.dev/router@2.0.0-beta.38

Major Changes

  • BREAKING: 404.tsx and error.tsx now render inside their layouts (with @layout/! modifiers), a route miss resolves the nearest 404.tsx, and the 404 page is prerendered for static hosts. Rename 404.tsx to 404!.tsx if you do not want to add the layout. (by @briancarbone in #8762)

  • BREAKING: SPA view transitions are now opt-in; set viewTransition={true} on QwikRouterProvider to re-enable them. (by @maiieul in #8778)

  • ✨ relocate built assets with output.assetFileNames; remove build.assetsDir handling (by @maiieul in #8817)

  • ✨ rename the Link prefetchBundle prop to prefetchBundles (by @maiieul in #8828)

Minor Changes

  • feat(router): automatically omit fully-prerendered, server-free routes from the production SSR route plan so their chunks tree-shake out of size-capped server bundles. (by @briancarbone in #8742)

  • ✨ route loaders gain a blockSSR option (default true); set blockSSR: false to run a loader in the background without blocking SSR (experimental, requires the blockSSR feature flag) (by @wmertens in #8793)

  • ✨ returning ev.redirect(), ev.error() or ev.rewrite() from a loader, action, request handler or server function now behaves the same as throwing them (by @wmertens in #8775)

  • feat(router): add an exclude option to rewriteRoutes to skip generating localized routes for matching path patterns. (by @briancarbone in #8751)

  • ✨ render SSG in a dedicated Vite build environment, so prerendered route code stays out of the deployed server bundle (by @briancarbone in #8760)

    SSG now runs from the buildApp step of the Vite builder. The Qwik CLI and adapters already build via createBuilder().buildApp(), so they need no change. Code that prerenders by calling Vite's programmatic build() directly must switch to builder.buildApp(), otherwise the SSG step is silently skipped.

  • ✨ add configurable server request body limits (by @Varixo in #8839)

Patch Changes

  • 🐞🩹 render navigation state before loading the next route (by @Varixo in #8821)

  • 🐞🩹 prerendered routes are now correctly excluded from the server route plan (by @briancarbone in #8759)

  • fix(router): honor the routeLoader$ id option so loaders created through a shared wrapper (which share one optimizer-assigned QRL hash) get distinct ids instead of all but the first being silently deduped in getModuleRouteLoaders. A dev-mode warning is now logged when two distinct loaders share an id. (by @maiieul in #8749)

  • 🐞🩹 prevent cold dev route loader requests from failing during SPA navigation (by @Varixo in #8787)

  • 🐞🩹 keep expiring loader responses private by default (by @Varixo in #8839)

  • 🐞🩹 action redirects work again (by @wmertens in #8780)

  • 🐞🩹 resolve image jsx imports with extra query parameters. (by @Varixo in #8753)

  • 🐞🩹 avoid prefetching loader data already fetched by route loaders (by @wmertens in #8836)

  • 🐞🩹 keep Azure response collection work proportional to output size (by @Varixo in #8839)

  • 🐞🩹 keep deeply nested form parsing work proportional (by @Varixo in #8839)

  • 🐞🩹 ensure SPA navigation correctly refreshes route loader data for catch-all routes, including when loader data is shared through context (by @Varixo in #8748)

  • 🐞🩹 routeLoader$ fail() now sets the loader value to { failed } instead of throwing an error, as it was before. (by @wmertens in #8756)

  • 🐞🩹 prerendered route loaders no longer 404 when the client and server are built as separate processes (by @briancarbone in #8760)

  • 🐞🩹 route loader no longer resolves to undefined on the first dev SPA navigation (by @briancarbone in #8770)

  • 🐞🩹 routeLoader$ not re-running during SPA navigation between URLs that match the same catchall route (by @Varixo in #8730)

  • 🐞🩹 prefix dev CSS and HMR URLs with Vite base (by @Varixo in #8837)

  • 🐞🩹 refetch re-exported route loaders after navigation (by @wmertens in #8792)

  • 🐞🩹 route action type allows invalidate without validators (by @wmertens in #8807)

  • 🐞🩹 preserve scroll after spa action submits (by @Varixo in #8797)

  • 🐞🩹 hot-reload route-imported CSS in dev without a server restart (by @briancarbone in #8725)

  • 🐞🩹 streaming server$ no longer crashes the Bun server on client disconnect (by @aggyomfg in #8798)

  • 🐞🩹 register aliased server functions used only in client code like visible tasks (by @Varixo in #8818)

  • 🐞🩹 adapter post-build runs with ssg disabled, and the ssg build skips minify/sourcemaps (by @wmertens in #8806)

  • 🐞🩹 the ssg build no longer bundles the unused deploy server entry (by @wmertens in #8806)

  • 🐞🩹 a prerendered route's loader with no static sidecar now falls through to SSR instead of failing as a missing static asset (by @briancarbone in #8760)

  • 🐞🩹 preserve strict loader URL isolation during route resolution (by @wmertens in #8836)

  • 🐞🩹 ensure dev SPA navigation loads route loader data correctly for catch-all and base-prefixed routes (by @Varixo in #8805)

  • Updated dependencies [96fe9e1, b0bdbf3, 77ae28f, dbdf85f, 570aec5, b5a74df, 3672ae5, 2e2a913, 1921d7a, 8e75051, e28ae7c, 3710734, e9d5d98, 12387da, e70b299, 9fd1303, bed0127, 1da9aa6, f9a0e83, 2a47192, 3a0df67, ee013ae, d3b6678, 885367a, 8fc5762, 03fae8a, fd9f197, 4917019, abaae23, 15ea2d8]:

@qwik.dev/core@2.0.0-beta.38

Major Changes

  • ✨ relocate built assets with output.assetFileNames; remove build.assetsDir handling (by @maiieul in #8817)

  • 🐞🩹 sync computed$ errors also go in .error and also rethrow on .value read (by @wmertens in #8807)

Minor Changes

  • ✨ useComputed$ accepts async functions and provides a compute context with track(); useAsync$, createAsync$, and AsyncSignal are deprecated in favor of it (by @wmertens in #8807)

  • ✨ improve client resume responsiveness by splitting startup DOM processing into smaller tasks (by @Varixo in #8575)

  • ✨ improve client resume responsiveness by splitting state processing into smaller tasks (by @Varixo in #8579)

  • ✨ Add experimental Show control-flow component with when$, then$, and optional else$ branches. (by @Varixo in #8624)

Patch Changes

  • 🐞🩹 preserve deferred attribute values during server rendering (by @Varixo in #8839)

  • 🐞🩹 preserve camelcase html attributes after client resume (by @Varixo in #8838)

  • 🐞🩹 validate element names during server rendering (by @Varixo in #8839)

  • 🐞🩹 preserve element keys during server rendering (by @Varixo in #8839)

  • 🐞🩹 clientOnly async signals now resume on pages without other serialized state (by @wmertens in #8807)

  • 🐞🩹 clientOnly option on useComputed$ now skips SSR computation (by @wmertens in #8807)

  • 🐞🩹 dedupe the ssr already-streamed-chore dev warning to once per host (by @maiieul in #8808)

  • 🐞🩹 the built-in dev-time eslint linter now targets es2022 (by @maiieul in #8810)

  • Dev-mode QRL segments now resolve even when their parent module was never loaded in the requesting Vite server (e.g. Vitest browser mode or SSR rendered in a separate server). The dev server transforms the parent on demand instead of erroring with "module does not exist in the build graph". (by @maiieul in #8816)

  • Fix SSR in-order streaming not flushing before awaiting a component-body promise. (by @AmariahAK in #8820)

  • 🐞🩹 release pending store state after failed deserialization (by @Varixo in #8839)

  • 🐞🩹 duplicate projected element children when a component throws a promise on first render (by @maiieul in #8715)

  • 🐞🩹 resume multiple SSR containers on the same page (by @maiieul in #8799)

  • 🐞🩹 validate serialized object data before restoration (by @Varixo in #8839)

  • 🐞🩹 reject invalid serialized Promise dependencies (by @Varixo in #8839)

  • 🐞🩹 reduce component rerender when props are the same (by @Varixo in #8735)

  • 🐞🩹 surface a failed container resume — report it and unblock whenContainerDataReady waiters — instead of swallowing the error into a silent hang. (by @maiieul in #8772)

  • 🐞🩹 surface a failed vnode-data resume — report it and unblock the whenVNodeDataReady waiters — instead of swallowing the error into a silent hang. (by @maiieul in #8773)

  • 🐞🩹 prevent large updates that span multiple frames from restarting incorrectly and missing pending UI changes (by @Varixo in #8743)
