What Decoupling TYPO3 Actually Means — And What Stays The Same

Your TYPO3 deployment ships with EXT:headless installed. That extension exposes your content types, navigation trees, forms, and plugins as JSON API endpoints. A Next.js application consumes those APIs and renders server-side or static pages at the edge. Your editorial team sees the same backend workspace they've always used. Your visitors hit a frontend that loads in under a second. The decoupling means TYPO3 updates no longer take down your public site, because the frontend and backend deploy independently. Your multilanguage setup stays intact — site trees, language fallbacks, workspace previews all flow through the headless layer. What changes is performance, hiring, and the fact that a frontend deploy no longer touches your database server.

Waar projecten falen

Monolithic TYPO3 renders every page server-side on every single request That means slow TTFB, poor Core Web Vitals, and search rankings that quietly slip.

The frontend's locked to Fluid templates and jQuery-era patterns Good developers won't touch it, and hiring gets harder every year.

Multilanguage and multidomain setups turn into TypoScript spaghetti over time One content update can silently break other locales—and you won't find out until someone complains.

Extensions like EXT:form and EXT:news don't just work headless out of the box—they need custom JSON mapping Skip that step and you end up with a half-migrated site where forms don't submit and news feeds return nothing.

When backend and frontend share the same deployment, a TYPO3 core update can take down your entire public-facing site That's a bad day.

Without static generation or edge caching, your server costs climb in lockstep with traffic instead of staying flat. Server costs scale linearly with traffic instead of staying flat

Compliance

EXT:headless Configuration

We install and configure the FriendsOfTYPO3 headless extension with site YAML flags, redirect middleware, and custom JSON output. Every content element ends up with a clean, typed API contract before we write a single line of frontend code.

Content Element Mapping

Every content element—standard and custom—gets mapped to a TypeScript interface and a matching React component. Nothing gets left out.

Multilanguage & Multidomain

We replicate your TYPO3 language fallback chains and domain routing in Next.js using i18n routing and middleware. All your locale URLs stay intact, so there's no SEO disruption at cutover.

Form & Extension Support

EXT:form, EXT:news, EXT:powermail, EXT:felogin, and EXT:solr each get dedicated Next.js integrations—proper POST handling, finisher support, the works.

SEO & Redirect Preservation

Every URL, meta tag, and 301 redirect gets exported from TYPO3 and rebuilt in Next.js. Structured data and canonical tags come with it.

Performance Benchmarking

We run Lighthouse audits before and after migration on every template. The target is 90+ across Performance, Accessibility, Best Practices, and SEO.

Wat we bouwen

Renders every page server-side on every request — TTFB climbs, Core Web Vitals tank, Google filters you down

Static generation at build + ISR on demand — your high-traffic pages serve from the edge, editorial changes go live in seconds

Locks your frontend to Fluid templates and jQuery patterns that drive modern developers away

TypeScript component library built from your JSON schema — developers actually want to work on your stack

Turns multilanguage and multidomain into TypoScript debt that silently breaks other locales when you publish

Workspace previews and language fallbacks flow through the headless layer without TypoScript rewrites

Ships EXT:form and EXT:news without headless JSON mapping — half your site stops working post-migration

EXT:form, EXT:news, and custom CEs map to dedicated Next.js components with full API coverage audited upfront

Couples backend and frontend deployment so a TYPO3 core update can take your entire public site offline

Frontend deploys to Vercel independently — TYPO3 updates never touch your public-facing site

Scales server costs linearly with traffic because there's no static generation or edge caching layer

Edge caching + static pages flatten your infrastructure costs regardless of traffic spikes

Ons proces

TYPO3 Audit & API Mapping

We start by inventorying every page type, content element, extension, language, and domain in your TYPO3 instance. You get a complete JSON API contract and a migration scope document before anything gets built.

Week 1-2

EXT:headless Setup & Customization

Next, we install and configure the headless extension, write TypoScript overrides for custom CEs, set up site YAML flags, and verify JSON output for every content type.

Week 2-3

Next.js Frontend Build

Then we build the component library, routing, i18n setup, forms, and authentication layer in Next.js—each component tested against the live TYPO3 API as we go.

Week 3-6

SEO Migration & QA

Before launch, we import all redirects, validate every URL, run Lighthouse audits, do cross-browser testing, and run a side-by-side content comparison against the original site.

Week 6-7

Cutover & Post-Launch Support

Cutover is a DNS switch with zero-downtime deployment. After that, you get 30 days of monitoring, bug fixes, and editor training on the new preview workflow.

Veelgestelde vragen

Can I keep using TYPO3 as my backend after migrating to Next.js?

Yes—and that's really the whole point. Your editors keep working in TYPO3 exactly as they do now: creating pages, managing content, handling translations. The EXT:headless extension exposes all of that as JSON APIs. Next.js consumes those APIs and handles everything on the frontend. Two systems, cleanly separated, neither dependent on the other.

Which TYPO3 extensions are supported in headless mode?

EXT:headless supports EXT:news, EXT:form, EXT:powermail, EXT:felogin, EXT:gridelements, and TYPO3 Solr out of the box. Custom extensions need TypoScript overrides to expose their data as JSON—we audit every installed extension during discovery and build those custom mappings where needed.

How long does a TYPO3 to Next.js migration take?

A typical mid-size migration—200 to 500 pages, multiple languages, standard extensions—takes 6 to 8 weeks. Larger sites with custom content elements, complex form workflows, or Solr integrations can run 10 to 12 weeks. We give you a fixed timeline during scoping, not a vague range.

Will my SEO rankings be affected during the migration?

We preserve every URL, redirect, canonical tag, hreflang attribute, and structured data block from your current site. Next.js static generation usually improves Core Web Vitals noticeably, which tends to help rankings. We run audits before and after to catch any discrepancies before cutover.

What TYPO3 version do I need for headless mode?

EXT:headless requires TYPO3 v9.5 or higher—though we'd strongly recommend v11 or v12 for the best API support and long-term security coverage. Running something older? We can fold a TYPO3 core upgrade into the migration project with an adjusted scope.

Where does the Next.js frontend get deployed?

We typically deploy to Vercel for edge caching, instant rollbacks, and built-in preview deployments. Your TYPO3 backend stays where it is; the two systems communicate over HTTPS APIs. If your compliance requirements call for AWS, Netlify, or self-hosted Node.js infrastructure, we can work with that too.
