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.

• 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

Criteria	Sanity v3	Payload 3.x	Strapi 5	Contentful	Storyblok
Hosting	Cloud (free tier)	Self-hosted / Cloud	Self-hosted	Cloud	Cloud
Schema Definition	Code (JS/TS)	Code (TS)	Admin UI / Code	Web UI	Web UI
Query Language	GROQ	REST / GraphQL	REST / GraphQL	GraphQL / REST	REST / GraphQL
Rich Text	Portable Text	Lexical / Slate	Blocks	Rich Text API	Rich Text
TypeScript	★★★★★	★★★★★	★★★★	★★★	★★★
Real-time	★★★★★	★★★★	★★★	★★★	★★★★
Visual Editing	Sanity Studio	Admin Panel	Admin Panel	Web App	Visual Editor
Best For	Developers	Code-first teams	Open-source fans	Enterprise	Marketing teams

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

// 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' }),
  ],
});

// 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

// 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)

// 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

// 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.

Implementasi Pola Kunci (TypeScript)

1. Definisi Skema Sanity v3 (Schema-as-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

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

// 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 });
}
