Our headless frontend currently runs on Nuxt 3 and talks to a Strapi 3 backend. I now need the codebase lifted to Nuxt 4 while keeping every existing feature exactly as it is—no regressions, no added plugins, no extra modules. You’ll be working with a fairly clean repository and I can supply some documentation that outlines the folder structure, build commands and Strapi endpoints; it covers the essentials but is not exhaustive. The upgrade must leave our routing, API calls, SEO meta setup, and page-level logic working identically. I’ll handle QA on staging, but I expect all unit tests and the production build to pass before hand-off. Deliverables • Updated project running on Nuxt 4, ready for production • All existing functionality verified as unchanged • Short migration note explaining any breaking-change fixes applied Please share one or two Nuxt upgrade projects you’ve completed, a brief outline of your proposed approach, and a realistic timeline for completion.
