Next.js agency: App Router, strict TypeScript and React
We do not just consume the React ecosystem: we contribute to it. Our plugins are published on npm and run in production on the sites we operate.
Most representative plugin
npm install @isomorph-agency/strapi-plugin-linkNext.js App Router, strict TypeScript, Server Components: these are not sales arguments. They are the constraints we impose on every project, because they produce faster, safer and more maintainable sites.
What we build with Next.js
App Router development
Server Components, Server Actions, API routes, native cache management. Our packages declare their supported versions in their package.json, readable on npm.
Strict TypeScript
No compromise on type rigour. A bug caught at compile time costs less than a bug caught in production.
Strapi v5 integration
Content modelling, Dynamic Zones, custom fields via our @isomorph-agency/strapi-plugin-link plugin. Front-end and back-end share the same types.
See our Strapi agency page for projects built on a Strapi v5 back-end.
Performance and Core Web Vitals
LCP, INP, CLS measured in real data (CrUX). Optimisations target the metrics that matter for Google Search.
RGAA 4.1.2 accessibility
Semantic HTML, verified contrasts, keyboard navigation, visible focus. This is not a billable option.
Deployment and hosting
Front-end on Vercel, Strapi back-end on Scaleway (France). Reproducible stack, documented, transferable to another team.
Why we host on French infrastructure (in French): our article on sovereign hosting.
