Quick answer
Which preset do I use to static-render Nuxt?
Use nitro preset:static or nuxt generate. SSR / CSR behavior differs across Nuxt majors — validate hydration before upgrading.

In-depth analysis
Nuxt is Vue's meta-framework, hybrid by default with first-class static generation. nuxt generate or nitro preset:static produces pure static HTML, ideal for edge distribution. Troubleshoot by three layers — build, deploy, runtime — diagnose by symptom, never blind-trial.
// nuxt.config.ts — full-site static generation
export default defineNuxtConfig({
ssr: true,
nitro: { preset: 'static' },
});

- Build, deploy, or runtime layer identified
- Relevant logs and status codes captured
- Fix verified and reproducible
- Fix notes recorded for reuse
FAQ & pitfalls
Why does my Nuxt client hydration fail?
Usually mismatched SSR vs CSR environment variables. Unify the runtime variable source to keep server and client rendering aligned.
How do I cache Nuxt static pages at the edge?
generate output is atomically replaced; hash-named assets get long cache. Dynamic data is fetched on the client and does not depend on server cache.

- 01
Why is my Astro component's interactivity not working?
Components ship as zero-JS HTML by default, so an interactive one needs a client:* directive (client:load, client:visible, …). Without it the script is never bundled into the page.

Why is my custom Tailwind v4 brand colour not applied?
Colours must be declared in @theme (for example --color-brand). A missing @tailwindcss/vite plugin, or a leftover v3 config, makes bg-brand silently render nothing.

Why are _headers / _redirects not taking effect?
Both files must sit at the root of the output directory (dist/); anything under src/ is never uploaded. A purely static project should not add _worker.js either — that gives up the zero-cold-start advantage.
