Modern Next.js & React.js Full Stack Development

THE POWER OF MODERN JAMSTACK WEB DEVELOPMENT

When considering a new website, businesses often face the difficult decision of choosing the right technology, approach and partner. Template solutions offer speed and low initial cost but quickly become restrictive, forcing business processes to fit the software. CMS platforms like WordPress are great for content management but can become bloated, slow and difficult to maintain.

A modern approach using flexible Jamstack frameworks like React.js and Next.js development means the software is engineered to fit your exact business needs and future growth plans. This custom approach avoids the limitations of off-the-shelf themes, providing a unique front-end design, superior performance, the ability to integrate with any third-party systems, and take advantage of state-of-the-art tools like AI. We build Jamstack solutions that are owned by you, without vendor lock-in or unnecessary bloat.

REACT.JS & NEXT.JS Frequently Asked Questions

Why do you offer Next.js and React.js services together rather than one or the other?

For many projects, Next.js and React are two halves of the same story – React powers the user interfaces, while Next.js web applications provide SSR, SSG, routing and API features. Combining them reflects how we work in practice, meaning we tailor the framework to your needs rather than forcing you down a single‑framework path.

Can you migrate an existing website or application to Next.js or React.js?

Absolutely. We specialise in migration projects where legacy systems or CMS sites like WordPress can be replaced with modern Next.js or React development services. Our process starts with an audit to identify content, user interfaces, functionality and SEO considerations, then we build a migration roadmap that preserves your data and redirects old URLs. You end up with a faster, more scalable platform without losing existing search rankings or user data.

Do you provide headless and eCommerce integrations?

Yes. Our full‑stack team builds headless content management and bespoke eCommerce solutions using Next.js, React and open‑source platforms like Magento or WooCommerce. We connect the frontend development to your preferred CMS or payment gateway via custom APIs, giving you the freedom to manage content and transactions securely while offering a blazing‑fast interface.

How does your React expertise enhance user experience?

React’s component‑based architecture allows us to create interactive user interfaces with reusable components and efficient state management. This modularity means we can rapidly build complex interfaces and web apps while maintaining consistent design patterns. For example, a single React SPA can deliver seamless transitions and app‑like responsiveness, keeping visitors on your site longer and boosting engagement.

What’s the difference between static websites, single‑page applications (SPAs) and hybrid solutions?

In the old days, a static site meant one built with HTML, CSS and client-side JavaScript. With modern Jamstack web development, static site pre‑builds where all pages are created at compile time for maximum speed and security. A single page application fetches data dynamically without reloading the page, providing a smooth app‑like feel. Hybrid solutions, like those enabled by Next.js web applications, combine both, i.e., you can serve static pages for evergreen content and dynamic pages where real‑time data is needed. We help you choose the right model based on your audience, content update frequency and growth plans.

How do server‑side rendering (SSR) and static site generation (SSG) improve performance?

Sites built with Next.js can pre‑render pages ahead of time or on the server, meaning visitors get an immediate response without waiting for heavy scripts. Research shows that 53% of people leave a page if it takes longer than three seconds to load on their mobile device. By combining SSR and SSG with automatic code splitting (loading only the code needed for each page), we create lightning‑fast user interfaces that keep users engaged and improve conversion rates.

Do you follow accessibility and inclusive design principles?

Yes. As a responsible development agency, we build to WCAG guidelines and test across devices to ensure our interfaces can be used by as many people as possible. From semantic HTML to keyboard navigation, colour contrast and screen‑reader support, accessibility is baked into our process rather than an afterthought.

Which industries benefit most from your Next.js & React solutions?

Our clients span charities, retailers, manufacturers and B2B service providers. Businesses that rely on dynamic content, app-like experiences or complex data visualisation gain the most from our approach. With React and Next.js, we can build robust dashboards, web apps, membership portals or booking systems that scale as your business grows.

How does AI‑augmented development improve your service?

We leverage AI tools during planning and development to automate repetitive tasks, generate boilerplate code and catch potential bugs early. This frees our engineers to focus on complex problem‑solving and creative design. By blending AI with human insight, we deliver high‑quality results faster and reduce technical debt — all without compromising on security or quality standards.

How do Core Web Vitals relate to business results?

Google’s Core Web Vitals are metrics that measure real‑world user experience. A one‑second delay in mobile load times can reduce conversion rates by up to 20%. Our focus on performance optimisation and SSR helps you achieve green Lighthouse scores, which not only pleases search engines but also keeps your visitors engaged. Faster sites are more likely to convert, and we quantify these improvements through analytics and user feedback.

What is state management and why is this important in React projects?

As applications grow, managing data flow between components becomes tricky. Effective state management allows your interface to stay predictable, maintainable and easy to debug. We use state libraries and context patterns tailored to each project, ensuring your custom React development remains scalable and free of confusing spaghetti code.

Do you build APIs or integrate third‑party services?

Yes. Our engineers design custom APIs and integrate external services (such as payment processors, CRM systems or marketing tools) to create seamless data flows. Because React and Next.js are unopinionated, we can connect your web apps to virtually any service, ensuring your application remains flexible and future‑proof.

How do you handle security in React and Next.js projects?

Security is more than a checkbox. It’s an ongoing mindset. Next.js benefits from server‑side execution and built‑in protections that reduce exposure of sensitive data. We follow secure coding practices, enforce HTTPS, sanitise inputs and implement proper authentication and authorisation. When working with headless CMS or eCommerce systems, we ensure data travels through encrypted APIs and only authorised users can access admin interfaces.

Can you build progressive web applications (PWAs) or mobile apps using your tech stack?

Certainly. We use React to craft responsive interfaces and add PWA features such as offline caching, push notifications and home‑screen installation. For mobile, our team can spin up companion apps using React Native, sharing a common component library for consistency and cost‑effectiveness. This gives you a unified brand experience across web and mobile without duplicating effort.

How do you optimise sites for search engines when using modern JavaScript frameworks?

Next.js provides features like dynamic routing, meta tags and server‑side rendering that make your content discoverable by search engines. We also ensure proper schema markup, generate sitemaps and optimise page titles and descriptions. Combined with our in‑house SEO expertise, these technical factors help your site achieve the rankings it deserves while delivering a smooth user experience.
