@lssm/lib.presentation-runtime-next

Next.js lane for contract-driven marketing SEO / LLMO. It maps the framework-neutral metadata produced by @lssm/lib.presentation-runtime-core/marketing into Next.js primitives and serves AI-discovery artifacts.

This is the only presentation-runtime package allowed to import next. presentation-runtime-core and presentation-runtime-react stay Next-free.

Adapters

| Export | Purpose | | ------ | ------- | | toNextMetadata(meta, opts?) | NormalizedMetadata → Next Metadata (hreflang via negotiateLocale). | | JsonLd, StructuredData, serializeJsonLd | JSON-LD <script> rendering from resolved schema.org shapes. | | buildSitemap(blueprint, opts?) | AppBlueprintSpec.routes → MetadataRoute.Sitemap. | | buildRobots(aiDiscovery, opts?) | AiDiscoveryConfig.crawlerPolicy → MetadataRoute.Robots. | | createLlmoRouteHandlers(emitter, opts?) | /llms.txt, /llms-full.md, /agents.json route handlers with CDN cache headers. |

Usage

Page metadata + JSON-LD

// app/pricing/page.tsx
import type { Metadata } from 'next';
import { transformAppConfigSeo } from '@lssm/lib.presentation-runtime-core/marketing';
import { toNextMetadata, StructuredData } from '@lssm/lib.presentation-runtime-next';
import { resolvedAppConfig } from '@/app-config';

const normalized = transformAppConfigSeo(resolvedAppConfig, { routePath: '/pricing' });

export const metadata: Metadata = toNextMetadata(normalized);

export default function PricingPage() {
  return (
    <>
      <StructuredData metadata={normalized} />
      {/* … */}
    </>
  );
}

sitemap + robots

// app/sitemap.ts
import { buildSitemap } from '@lssm/lib.presentation-runtime-next';
import { blueprint } from '@/app-config';
export default function sitemap() {
  return buildSitemap(blueprint, { supportedLocales: ['en', 'fr'], defaultLocale: 'en' });
}

// app/robots.ts
import { buildRobots } from '@lssm/lib.presentation-runtime-next';
import { blueprint } from '@/app-config';
export default function robots() {
  return buildRobots(blueprint.aiDiscovery, {
    baseUrl: 'https://contractspec.dev',
    sitemapUrl: 'https://contractspec.dev/sitemap.xml',
  });
}

LLMO route handlers (ISR + CDN cache)

// app/llms.txt/route.ts
import { createLlmoRouteHandlers } from '@lssm/lib.presentation-runtime-next';
import { llmoEmitter } from '@/app-config'; // @lssm/lib.content-gen LlmoEmitter

// Next.js segment config must be statically analyzable; keep this literal in the route file.
export const revalidate = 3600;
export const GET = createLlmoRouteHandlers(llmoEmitter).llmsTxt;

The LlmoEmitter contract is declared structurally in ./llmo-routes so the concrete @lssm/lib.content-gen emitter is injected by the app.
