React framework for web apps

Next.js is a React framework for building websites and web applications that combines server-side, static and incremental rendering.

What is Next.js?

Next.js is an open-source framework built on React and maintained by Vercel for creating websites and web applications. A single project can mix statically generated pages, pages rendered on the server for each request (SSR) and pages regenerated in the background (ISR), while server logic such as form handling or calls to external APIs sits alongside the interface. With server or static rendering, search engine crawlers receive ready HTML with content rather than an empty page waiting for a script.

How we use it at Koda Plus

We choose Next.js when a website turns into an application – with sign-in, customer accounts, a data dashboard or integrations with ERP, CRM or a payment gateway. It powers the storefront of a tyre and wheel shop built on Medusa, the website and admin panel for the insulation company Wekert, and the website of a training and coaching firm. We match the rendering strategy to each type of page, because rendering everything dynamically is the most expensive option. The client receives the full code and every access credential, so the project can run on Vercel, on their own server or in a container.

When it makes sense

  • The site has customer accounts, a dashboard or live data
  • A headless store, e.g. on Medusa.js, needs its own storefront
  • A large catalogue needs fresh data and solid SEO at the same time
  • ERP, CRM or payment gateway integrations must run server-side

Frequently asked questions
Next.js

  • What is the difference between Next.js and React?

    React is a library for building the interface – components and their state. Next.js is a framework built on React that adds routing, server-side rendering, static generation and server logic. You still write a Next.js app in React, but you don't have to assemble those pieces from separate libraries yourself.

  • Next.js or Astro – which should I choose for my website?

    If the site mainly presents content and needs to be as fast as possible, Astro is usually enough and cheaper to maintain. Next.js makes sense once you need user accounts, live data, a dashboard or substantial integrations.

  • Do I have to host Next.js on Vercel?

    No. Vercel is the simplest option, but Next.js also runs on your own Node.js server or in a container. Hosting cost depends mostly on how many pages render per request and how much traffic is served from cache and a CDN.
