Orchestration & Integration

Connects and orchestrates with domain skills:

• Frontend & Design System: senior-frontend, design-system-architect, ui-ux-pro-max, modern-web-guidance, and anti-slop for rendering structured CMS blocks (Portable Text, Lexical, Blocks), typography hierarchies, and component layouts.
• Visual Auditing & Previews: visual-ui-auditor for validating real-time visual draft mode, iframe preview boundaries, and responsive layout fidelity.
• Frameworks: nextjs-app-router-expert (SSR/ISR on-demand tag revalidation) and astro-framework-expert (Content Collections and static site generation).
• Editor & SEO: rich-text-editor-expert (custom authoring tools), wordpress-headless-expert (WPGraphQL & ACF Pro migrations), documentation-site-expert (MDX/Mintlify knowledge bases), and seo (schema markup, dynamic sitemaps, Open Graph images).
• Orchestration: brainstorming and zero-to-prod-orchestrator for structured content architecture.

Description

Expert guide for selecting, integrating, and optimizing Headless CMS platforms in modern web applications. Covers Sanity v3 (GROQ, Portable Text, Content Lake), Payload CMS 3.x (TypeScript-first, code-defined schemas), Strapi 5 (open-source, self-hosted), Contentful (enterprise, GraphQL), and Storyblok (visual editing). Includes content modeling, preview mode, webhook-based revalidation, and migration strategies.

Trigger Conditions

• Choosing or integrating a headless CMS.
• Building content-driven websites (blogs, docs, marketing sites).
• Implementing CMS preview/draft mode in Next.js or Astro.
• Designing content models and structured content schemas.
• Migrating from WordPress or monolithic CMS to headless.

CMS Selection Guide

Recommendation: Use Sanity v3 for developer-heavy teams. Use Payload CMS when you need full TypeScript control and self-hosting. Use Strapi for open-source requirements.

Core Patterns

1. Sanity v3 Integration

typescriptCopy code
// sanity.config.ts — Schema-as-code
import { defineConfig, defineField, defineType } from 'sanity';

export const postSchema = defineType({
  name: 'post',
  title: 'Blog Post',
  type: 'document',
  fields: [
    defineField({ name: 'title', type: 'string', validation: (r) => r.required() }),
    defineField({ name: 'slug', type: 'slug', options: { source: 'title' } }),
    defineField({ name: 'body', type: 'array', of: [{ type: 'block' }] }),
    defineField({ name: 'publishedAt', type: 'datetime' }),
  ],
});

typescriptCopy code
// Fetching with GROQ in Next.js App Router
import { createClient } from 'next-sanity';

const client = createClient({
  projectId: process.env.SANITY_PROJECT_ID!,
  dataset: 'production',
  apiVersion: '2026-08-01',
  useCdn: true,
});

// Server Component
async function BlogPage() {
  const posts = await client.fetch(
    `*[_type == "post"] | order(publishedAt desc) {
      title, slug, publishedAt,
      "excerpt": array::join(string::split(pt::text(body), "")[0..200], "")
    }`
  );
  return <PostList posts={posts} />;
}

2. Payload CMS 3.x Integration

typescriptCopy code
// payload.config.ts
import { buildConfig } from 'payload';
import { postgresAdapter } from '@payloadcms/db-postgres';
import { lexicalEditor } from '@payloadcms/richtext-lexical';

export default buildConfig({
  db: postgresAdapter({ pool: { connectionString: process.env.DATABASE_URL! } }),
  editor: lexicalEditor(),
  collections: [
    {
      slug: 'posts',
      fields: [
        { name: 'title', type: 'text', required: true },
        { name: 'content', type: 'richText' },
        { name: 'status', type: 'select', options: ['draft', 'published'] },
      ],
    },
  ],
});

3. Webhook Revalidation (Next.js)

typescriptCopy code
// app/api/revalidate/route.ts
import { revalidateTag } from 'next/cache';
import { NextRequest, NextResponse } from 'next/server';

export async function POST(req: NextRequest) {
  const secret = req.headers.get('x-webhook-secret');
  if (secret !== process.env.REVALIDATION_SECRET) {
    return NextResponse.json({ error: 'Unauthorized' }, { status: 401 });
  }
  const body = await req.json();
  revalidateTag(body._type); // Revalidate by content type
  return NextResponse.json({ revalidated: true });
}

4. Preview Mode Pattern

typescriptCopy code
// app/api/draft/route.ts — Sanity preview
import { draftMode } from 'next/headers';
import { redirect } from 'next/navigation';

export async function GET(req: NextRequest) {
  const { searchParams } = new URL(req.url);
  const secret = searchParams.get('secret');
  const slug = searchParams.get('slug');
  if (secret !== process.env.SANITY_PREVIEW_SECRET) {
    return new Response('Invalid token', { status: 401 });
  }
  (await draftMode()).enable();
  redirect(`/posts/${slug}`);
}

Production Checklist

• Webhook-based ISR revalidation configured.
• Preview/draft mode working with CMS studio.
• Image optimization pipeline (next/image or Sanity image URL builder).
• Content backup/export strategy defined.
• CORS and API permissions locked down.
• CDN caching for API responses configured.

Integrasi Orkestrasi

Terhubung dan mengorkestrasi bersama skill domain:

• Frontend & Design System: senior-frontend, design-system-architect, ui-ux-pro-max, modern-web-guidance, dan anti-slop untuk perenderan blok konten terstruktur CMS (Portable Text, Lexical, Blocks), hierarki tipografi, dan tata letak komponen.
• Audit Visual & Preview: visual-ui-auditor untuk validasi mode pratinjau langsung (draft mode), batas iframe preview, dan fidelitas tata letak responsif.
• Framework Modern: nextjs-app-router-expert (revalidasi tag on-demand SSR/ISR) dan astro-framework-expert (Content Collections dan static site generation).
• Editor & SEO: rich-text-editor-expert (komponen editor konten) dan seo (data terstruktur schema, sitemap dinamis, Open Graph).
• Orkestrasi: brainstorming dan zero-to-prod-orchestrator untuk arsitektur konten yang terstruktur.

Deskripsi

Panduan ahli untuk memilih, mengintegrasikan, dan mengoptimalkan platform Headless CMS dalam aplikasi web modern. Mencakup Sanity v3 (GROQ, Portable Text), Payload CMS 3.x (TypeScript-first, schema-as-code), Strapi 5 (open-source self-hosted), Contentful, dan Storyblok (visual editor). Termasuk modeling konten, preview mode, dan revalidasi instan berbasis webhook.

Kondisi Pemicu

• Memilih dan mengintegrasikan headless CMS untuk aplikasi konten.
• Membangun situs web kaya konten (blog, portal media, dokumentasi, landing page).
• Menerapkan fitur live preview / draft mode di Next.js atau Astro.
• Mengonfigurasi revalidasi cache instan saat konten diterbitkan di CMS.

Implementasi Pola Kunci (TypeScript)

1. Definisi Skema Sanity v3 (Schema-as-Code)

typescriptCopy code
// sanity.config.ts
import { defineConfig, defineField, defineType } from 'sanity';

export const skemaArtikel = defineType({
  name: 'artikel',
  title: 'Artikel Blog',
  type: 'document',
  fields: [
    defineField({ name: 'judul', type: 'string', validation: (r) => r.required() }),
    defineField({ name: 'slug', type: 'slug', options: { source: 'judul' } }),
    defineField({ name: 'isi', type: 'array', of: [{ type: 'block' }] }),
    defineField({ name: 'diterbitkanPada', type: 'datetime' }),
  ],
});

2. Query GROQ di Next.js 15 Server Component

typescriptCopy code
import { createClient } from 'next-sanity';

const sanity = createClient({
  projectId: process.env.SANITY_PROJECT_ID!,
  dataset: 'production',
  apiVersion: '2026-08-01',
  useCdn: true,
});

export async function ambilDaftarArtikel() {
  return await sanity.fetch(
    `*[_type == "artikel"] | order(diterbitkanPada desc) {
      judul, slug, diterbitkanPada,
      "ringkasan": pt::text(isi)[0..200]
    }`
  );
}

3. Revalidasi Cache Otomatis via Webhook Next.js

typescriptCopy code
// app/api/revalidasi/route.ts
import { revalidateTag } from 'next/cache';
import { NextRequest, NextResponse } from 'next/server';

export async function POST(req: NextRequest) {
  const secret = req.headers.get('x-webhook-secret');
  if (secret !== process.env.REVALIDATION_SECRET) {
    return NextResponse.json({ error: 'Tidak sah' }, { status: 401 });
  }
  const body = await req.json();
  revalidateTag(body._type); // Revalidasi cache berdasarkan tipe konten
  return NextResponse.json({ sukses: true });
}
