Next.js development for fast, search-friendly React applications
Next.js is a framework built on React that adds file-based routing, server-side rendering, static generation and server-side code. It suits products that need both a rich interface and pages that load quickly and rank well in search.
Next.js lets you choose, page by page, whether content is rendered at build time, on the server or in the browser, which is excellent for mixed sites such as a marketing site with a logged-in application behind it. It also handles images, fonts and code splitting well. The trade-off is added complexity: its server and caching model takes care to get right, and it works best on hosts that support it fully. For a simple content site, Astro is often lighter; for a pure internal tool, plain React may be enough.
What we build with Next.js
- Marketing sites with an integrated app
- eCommerce storefronts, including headless
- SaaS products with public and logged-in areas
- Content platforms and blogs
- Server-rendered dashboards
Next.js questions
Do we need Next.js or is React enough?
If search visibility, first-load speed or public pages matter, Next.js is usually worth it. For an internal tool behind a login, plain React with a simple build setup is often sufficient.
Where can a Next.js site be hosted?
It can run on specialist platforms, on any Node.js server or in containers on AWS, Google Cloud or Azure. We choose hosting based on the rendering features you actually use.
What is the difference between static generation and server rendering in Next.js?
Static generation builds pages ahead of time so they load instantly from a CDN, while server rendering builds each page on request for content that changes per user or minute by minute. Next.js lets you mix both, and we choose per page.
How does Next.js help with SEO?
Pages arrive as complete HTML that search engines can read immediately, and Next.js provides tools for metadata, sitemaps and structured data. Combined with good performance, this gives content pages a strong technical foundation for search.
Can Next.js connect to a headless CMS?
Yes. Next.js works well with most headless CMS platforms, and pages can be regenerated when editors publish so content stays fresh without full rebuilds.
Can we build API endpoints inside a Next.js project?
Yes. Next.js includes server-side route handlers suitable for form submissions, webhooks and light backend logic. For heavy business logic we usually recommend a separate backend service so responsibilities stay clear.
How do you handle images and performance in Next.js?
We use the built-in image optimisation to serve correctly sized, modern formats and lazy-load anything below the fold. We also keep client-side JavaScript to what each page genuinely needs and monitor Core Web Vitals.
Can you migrate an existing React app to Next.js?
Yes. Because Next.js is built on React, most components can be reused; the main work is moving routing, data fetching and rendering decisions into the Next.js structure. We usually migrate in stages to limit risk.
Is Next.js suitable for e-commerce?
Yes. Next.js is a common choice for headless storefronts because product and category pages can be fast and search-friendly, while cart and checkout remain dynamic. It pairs well with commerce platforms that expose an API.
How is authentication handled in a Next.js application?
We use established authentication libraries or your identity provider, with sessions protected on the server and sensitive routes checked before rendering. Secrets stay server-side and never reach the browser bundle.
