React & Next.js development
React and Next.js development for web apps, portals and content-led websites.
Orvenant builds React interfaces and Next.js applications for small and mid-sized businesses and agencies. Each part of a page gets the rendering it needs: prerendered HTML for content that search engines must read, server rendering for signed-in data and browser interactivity only where people work with the interface.
Illustration: a React component tree beside the page it composes. Each component snaps into its slot, the page settles as delivered HTML, and then only the interactive filters switch on.
Choose React and Next.js for interfaces people use, not only read.
React is a library for building interfaces from reusable components. It earns its place when visitors do real work in the browser: filter a catalog, configure an order, compare options, sign in or track a request. Next.js adds routing, server rendering and static generation on top of React, so one codebase can deliver complete, readable HTML to search engines and a responsive interface to signed-in users. We start from what each page must let a person do, what search engines must be able to read and how quickly the page has to respond, and choose the architecture from there.

Rendering, decided page by page.
Every page is a tree of components: a layout holds the header, navigation, content sections, a footer and perhaps a form or search filters. Not every part of that tree needs the same treatment. Sending JavaScript for content that never changes slows a page down, and signed-in data cannot be prerendered at all. We give each part of the site the rendering it needs and write the choice down, so later changes follow the same logic.
Service and content pages: prerendered HTML
Built ahead of time and served from a cache. Headings, text, links and metadata are in the HTML before any JavaScript runs, so search engines and AI crawlers can read them without running scripts.
Catalogs and articles that change: revalidated pages
Prerendered, then refreshed when an editor publishes or after a set interval, so content stays current without rendering every request.
Accounts and dashboards: server rendering per request
Rendered on the server with the signed-in user’s data, after permissions are checked there and before anything reaches the browser.
Filters, forms and configurators: client components
Only the parts that need browser state send JavaScript. The rest of the page stays plain HTML, which keeps it light.
What a React and Next.js build includes.
The proposal names the components, data sources and rendering choices before the team commits to a stack pattern. Each layer is built and reviewed together with the next.
Component library
Shared buttons, forms, cards and layouts, with their loading, empty, error and keyboard states designed and built, not only the finished screen.
Pages and routing
Clean URLs, page titles, canonical links and structured data generated from the same source as the content.
Data and APIs
Typed connections to your CMS, application backend or third-party services, with a defined result when a request fails or is slow.
View Node.js developmentAuthentication
Sign-in, sessions and role checks placed on the server, so a hidden button is never the only thing protecting a record.
Build and deployment
Repeatable builds, preview deployments for review and a tested way back to the previous release.
Performance budget
Image sizes, font loading and script weight checked on real pages, with bottlenecks fixed where measurement shows them.
A modern frontend for a WordPress or Joomla site.
If your content lives in WordPress or Joomla, React and Next.js can give it a new public interface while editors keep working in the CMS they know. This is often called a headless setup. When the underlying workflows also need to change, a complete rebuild can be the better route. Either way, we define the content source, editing preview, public rendering and publication behavior together, so a faster interface does not make daily editing harder.
Next.js for connected journeys
Published content and search metadata stay in the delivered HTML, while client components handle the parts that need browser state. Authenticated data gets clear boundaries.
View Web application developmentAstro for content-led sites
Astro suits service pages, editorial sites and other public content that needs only a few interactive components. We decide how a CMS update triggers a release, which pages need server behavior and how previews stay private.

When a custom backend is needed, we define API contracts, permissions and record ownership first. A frontend framework does not replace the business rules or the operating plan.

Do not let a framework decide the product.
Next.js offers strong conventions, but caching and hosting behavior depend on the version and the platform it runs on. We confirm the runtime, the hosting model and your team’s skills before relying on a feature. A marketing page does not need the architecture of an account dashboard, and part of the work may fit a CMS, an existing application or a simpler frontend better. When that is the case, we say so before you commit.
Tested in the browser, including when things go wrong.
We review key pages at mobile and desktop widths with keyboard and reduced-motion settings, then check what happens when loading is slow, content is stale, a form fails or scripts are delayed. Performance work follows measured bottlenecks, not the promise of a perfect score.
What we check before launch
- Content, headings and links present in the HTML before JavaScript runs
- Keyboard and screen reader paths through each key journey
- Loading, empty and error states for every data request
- Behavior on slow connections and with reduced motion
- Canonical URLs, metadata and structured data on each template
- Real content lengths at phone, tablet and desktop widths
Move to the new frontend without losing what already works.
Replacing a live site’s frontend is a migration, so it is rehearsed before traffic moves. We compare the old and new pages in their delivered HTML, test interactive journeys, review cache behavior with an editor publishing a real change and map every old address to its final page before the switch.
Inventory
Every URL, template and content type on the current site, with the pages that bring search traffic marked.
Gates: Inventory approved
Build in parallel
The new frontend runs on a private address with real content while the current site stays live.
Gates: Content matches
Compare
Text, headings, links, metadata and error responses checked page by page against the old site.
Gates: Redirects reviewed
Map redirects
Each moved address gets a permanent redirect to its closest new page.

Switch and watch
Traffic moves to the new frontend, then crawl errors, forms and key journeys are checked again on the live site.

Questions about React and Next.js.
Is Next.js good for SEO?
It can be. Next.js can deliver complete HTML from the server or at build time, so headings, text, links and metadata are readable without running JavaScript, which gives search engines a reliable page to index. Rankings still depend on useful content, a sound information structure and links. We get the technical delivery right and are clear that no framework guarantees visibility.
Should we use React on its own or with Next.js?
Use React on its own for a focused interface inside an existing site or application, such as a configurator or a dashboard. Choose Next.js when the same product also needs routing, server rendering and pages that search engines should find. For a mostly editorial site with a few interactive parts, Astro can be the simpler choice. We explain the tradeoff against your actual requirements before recommending one.
Can you build a headless WordPress or Joomla site with Next.js?
Yes. Editors keep publishing in WordPress or Joomla, and a Next.js or Astro frontend renders the public site from that content. We plan previews, publishing triggers, redirects and what happens when the CMS is unavailable, so the new frontend does not create a second editorial process.
Can you take over an existing React or Next.js codebase?
Yes, after a review. We look at the framework and dependency versions, the rendering choices, the tests, the deployment and who holds each account, then propose a bounded first piece of work before larger changes.
How much does a React or Next.js project cost?
Each project is priced in a written proposal after a free first conversation. Cost moves most with the number of page types and user roles, the integrations involved, any content or URL migration and the support you need after launch. Hosting and other third-party costs are listed separately.
Why work with Orvenant on a React or Next.js project?
Because the rendering, the integrations and the operating plan are designed together. Your first conversation is with Gary C., our client partner; the proposal sets out scope, price and review points in writing; and the handover documents components, content sources and deployment so your team can carry the work on. Orvenant also builds the APIs and automations a frontend depends on, so they are planned as one system.
