The latest news releases from the Qwik team

Patch Changes

• INFRA: migration from tsm to tsx (by @JerryWu1234 in #6877)

Minor Changes

• Async functions in useComputed are deprecated. (by @wmertens in #7013)

  Why?

  • Qwik can't track used signals after the first await, which leads to subtle bugs.
  • When calculating the first time, it will see it's a promise and it will restart the render function.
  • Both useTask and useResource are available, without these problems.

  In v2, async functions won't work.

  Again, to get the same functionality use useTask or useResource instead, or this function:

  export const useAsyncComputed$ = (qrlFn: QRL<() => Promise<any>>) => {
    const sig = useSignal();
    useTask(({ track }) => {
      const result = track(qrlFn);
      if (result && 'then' in result) {
        result.then(
          (val) => (sig.value = val),
          (err) => {
            console.error('async computed function threw!', err);
            throw error;
          }
        );
      } else {
        sig.value = result;
      }
    });
    return sig;
  };
  

• ✨ Expose unwrapStore as a low level AP (by @GrandSchtroumpf in #6960)

  This enables developers to clone the content of a useStore() using structureClone or IndexedDB

Patch Changes

• 📃 fix useResource docs example & remove unused demo (by @ianlet in #6893)

• 🐞🩹 QRL segment filenames are no longer lowercased. This was giving trouble with parent lookups in dev mode and there was no good reason for it. (by @wmertens in #7003)

• 🐞🩹 the type for <textarea> now accepts text children, as per spec. (by @wmertens in #7016)

• 🐞🩹 dev-mode QRL paths are now handled by Vite so they are the same as the parent paths. You can see this in the Sources section of the browser devtools, where the segments are now always next to their parents (when the parent is loaded). (by @wmertens in #7037)

• 🐞🩹 vite is now a peer dependency of qwik, qwik-city, qwik-react and qwik-labs, so that there can be no duplicate imports. This should not have consequences, since all apps also directly depend on vite. (by @wmertens in #6945)

• ✨ sync$ QRLs will now be serialized into the HTML in a shorter form (by @wmertens in #6944)

• 🐞🩹 cli build command appearing to "hang" on errors (by @shairez in #6943)

• ✨ Allow setting linkFetchPriority for modulepreload links in the prefetch strategy. Also fix the links in dev mode (by @GrandSchtroumpf in #6947)

Patch Changes

• 🐞🩹 MDX content no longer ignores Layout components. See the MDX docs for more information. (by @danielvaijk in #6845)

• 🐞🩹 SSG errors now show the path that failed (by @wmertens in #6998)

• 🐞🩹 Fixed action redirect regression where searchParams were appended (by @brandonpittman in #6927)

• 🐞🩹 Redirect, error, and fail request events no longer forcefully delete user-defined Cache-Control HTTP header value. (by @nelsonprsousa in #6991)

• 🐞🩹 vite is now a peer dependency of qwik, qwik-city, qwik-react and qwik-labs, so that there can be no duplicate imports. This should not have consequences, since all apps also directly depend on vite. (by @wmertens in #6945)

• 🐞🩹 Fixed MDX layout default export being ignored by transformer. (by @danielvaijk in #6845)

• 🐞🩹 Prevent unexpected caching for q-data.json (by @genki in #6808)

• 🐞🩹 Multiple rewrite routes pointing to the same route is no longer an error. (by @JerryWu1234 in #6970)

Patch Changes

• ✨ showing qrl parent names. (by @wmertens in #6881) in dev mode, qrl segments now start with their parent filename so it's easy to see where they came from. Furthermore, in production builds these filenames are also used so that origins in q-manifest.json are easy to understand.

• 🐞🩹 Optimizer now ignores unknown deps in graph that caused crashes during build (by @wmertens in #6888)

• 🐞🩹 Do not allow object methods to be serialized with style prop (by @jakovljevic-mladen in #6932)

• 🐞🩹 In dev mode, changes to QRLs now explicitly invalidate the segment so that the browser will reload it (by @wmertens in #6938)
