- Nitro middleware resolves page requests once and hands the answer to the render (event.context.seo); the route middleware reuses it - useCmsSeo: html lang, hreflang links, og:locale and exactly one JSON-LD script with one @graph (CMS nodes plus useSchemaNode nodes, merged by @id) - local module (configKey seo): cms (alias of public.seo.enabled), breadcrumbs, links.newTabHint, rootFiles, resolveFiles - GET /api/__seo__/resolve for client navigation through the Nuxt server - smoke harness: count=, exact header=, noheader=, reqheader=, repeated options, resolves/apicalls/noreport lines, --no-site; v0.1.1 suite runs unchanged against a backend without /site

// The server side of the resolve call: GET <apiBase>/resolve?url=<path and
|
|
// query>, forwarding the visitor's address so the backend's per-IP throttle
|
|
// (seo-resolve) keeps one bucket per visitor, also on route-cached renders
|
|
// (server/plugins/seo-client-address.ts records it). Any failure (timeout,
|
|
// 4xx, 5xx, an unexpected body) answers null and the page renders without
|
|
// CMS head tags (fail open); with the layer switched off nothing is called.
|
|
//
|
|
// Nitro auto-imports (useRuntimeConfig, $fetch) are used inside the
|
|
// functions only, so `node --test` can import this file.
