Qwik to WordPress: Migrating Resumable Apps to a CMS

Qwik is the framework that took the hydration problem seriously enough to invent a whole new model — resumability instead of hydration. The result is zero-JavaScript startup even for complex applications. What Qwik does not solve is the CMS problem: content is still files, editors are still developers, and every publish is still a Git commit. Migrating to WordPress plugs Qwik's compiled output into WordPress's editorial workflow. Editors get wp-admin, marketing gets plugins, and Qwik's resumability keeps working because the serialized state ships in the WordPress theme's HTML. The perceived speed of the site does not change — WordPress simply becomes the CMS layer that Qwik was never trying to be.

Qwik's build produces a directory of HTML files with serialized state and a set of lazily-loaded JavaScript symbols. Both ship in the WordPress theme. Every route becomes a WordPress page or template. Layouts wrap child routes. Qwik City's routeLoader$ output is baked into the HTML because it ran at build time. Client interactivity resumes on first user event, just as it did on the Qwik host. Styles compile into the theme's stylesheet. Assets from public/ copy to the theme root. Server-only constructs (server$, routeAction$) do not carry over and need WordPress-side replacements.

Run the static adapter build. In QwikCity that is `npm run build.static` after installing @builder.io/qwik-city/adapters/static. If your project uses a Node adapter, switch to static for the migration. Inspect the dist output and confirm every route is present. Qwik's build is fast enough that iterating locally is painless. Audit routeAction$ handlers. Each one needs a WordPress-side plan.

Upload your ZIP or connect GitHub. The pipeline detects Qwik, runs the static build, and consumes dist/. HTML files become templates. Assets rewrite. Total build time is typically about five minutes.

Standard trio of plugins: caching, SEO, SMTP. Replace routeAction$ handlers with REST endpoints or form plugins. Confirm the WordPress cache respects Qwik's asset cache headers so the lazy chunks are served with far-future expirations.

Do not attempt to migrate without switching to the static adapter. Node-adapter output cannot be served from WordPress directly. Do not forget to move routeAction$ handlers — those forms will silently stop submitting until replaced. Do run the free preview. Qwik's resumability is a novel model and worth verifying visually before you buy.

Upload on the homepage or connect GitHub. Preview before paying. Conversion typically takes about five minutes.
