Is Next.js App Router suitable for NHS HealthTech applications?

Yes — Next.js App Router with Server Components is excellent for NHS HealthTech. Server Components handle NHS FHIR R4 data server-side (health data never sent to client unless explicitly required — GDPR Article 25 data protection by design). Server Actions replace API routes for form submissions (clinical form data processed server-side). NHS Design System components can be used in Next.js without modification. ClickMasters uses Next.js App Router for all NHS web applications.

Should UK government digital services use Next.js or a bespoke GDS framework?

GDS does not mandate a specific frontend framework. GDS Service Standard requires: accessible (WCAG 2.1 AA), performant (< 3 seconds on 3G), and progressively enhanced (works without JavaScript). Next.js with GOV.UK Design System components satisfies all three. Many UK government services use Next.js. ClickMasters uses Next.js with GOV.UK/NHS Design System components for all GDS-assessed services.

Direct Answer

Next.js is the right default for most UK commercial applications: largest ecosystem, best Vercel/AWS deployment support, App Router (Server Components) for UK GDPR data minimisation (no client-side personal data), and the most UK developer familiarity. Remix is right for data-heavy applications with complex form workflows. Astro is right for content-heavy marketing sites where minimal JavaScript is the priority. React framework choice affects UK GDPR compliance (where data is processed), Core Web Vitals (affects Google Search ranking for UK eCommerce), and developer productivity.
