Next.js Migration in Lincoln
Migrating Lincoln applications to Next.js, which is a change of rendering model rather than a change of library. A single-page application assumes the browser holds the session, fetches everything itself and owns all state — and moving that to a framework which renders on the server touches authentication, data access and state together.
Why this comes up
The problem
The migration was scoped as swapping the build tool, and authentication assumes a token in browser storage the server cannot read.
What you get
What we deliver
- Authentication reworked for a model where the server renders on the user's behalf
- Data fetching moved server-side where it belongs, rather than lifted wholesale
- State reviewed, since much of what was client state no longer needs to be
- Routes migrated incrementally where the application allows it
- Environment variables audited, as the server and client boundary changes exposure
- Behaviour captured as tests before the code producing it is replaced

Next.js Migration in Lincoln — common questions
- Why does authentication need rework?
- Because the server now needs to know who the user is before it renders anything. A token held only in browser storage is invisible to it, so sessions typically move to cookies the server can read — which is a real change rather than a configuration adjustment.
- Can we migrate gradually?
- Usually yes, route by route, with both applications served behind one domain. That keeps each step small and reversible, which matters because rendering-model changes surface problems that only appear with real traffic and real sessions.
- What is easy to get wrong?
- Environment variables. Values that were safely server-side in the previous architecture can end up in the browser bundle if the boundary is misunderstood, and an API key shipped to the client is the kind of mistake that is trivial to make here.
- Will it be faster afterwards?
- If the rendering choices are made deliberately, generally yes — less JavaScript and data fetched closer to the source. A migration that keeps everything client-rendered inside the new framework gains very little and adds a build system.
- Do you work with businesses across Lincolnshire?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout East Midlands, including Lincoln and the surrounding Lincolnshire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Lincoln businesses do you usually work with?
- Agri-food traceability and processing systems, and engineering supply chain integration on long procurement timelines. Beyond that we work across Agriculture, Food Production, Engineering, Higher Education and Defence.
- Do you cover the areas around Lincoln?
- Yes — we work throughout East Midlands, including Nottingham, Peterborough, Sheffield. Lincoln is an urban area of roughly 130,000+, and we take on work across the wider Lincolnshire region rather than the city boundary alone.
