Next.js: The Best React-Based Framework
Next.js has quickly taken the tech world by storm thanks to its capabilities and advanced features.
Next.js has quickly taken the tech world by storm thanks to its capabilities and advanced features. In this article, we'll explore its main characteristics and why it represents an important choice for modern projects.
What Is It?
It is a React-based framework that uses TypeScript — a language that adds static typing to JavaScript, increasing code safety — to simplify the creation of web applications. It allows you to build performant and scalable software while reducing the complexity of the development process.
What Is It Used For?
It is ideal for complex scenarios, especially cases that require high performance and optimized SEO. Some of its main use cases include:
- Server-Side Rendering (SSR): the application's content is generated by the server before being sent to the client. This positively impacts search engine indexing.
- Static Site Generation (SSG): allows you to generate static pages, reducing processing times and improving content accessibility. These are ideal for sites that don't require immediate updates.
- Serverless APIs: it enables you to build APIs directly within the project, using serverless functions that easily adapt to scalability and performance requirements.
Why Is It Important?
Next.js simplifies development by solving many of the common challenges developers face every day. Here's why it's essential:
- SEO and Performance: optimizes SEO and search rankings.
- Flexibility: adapts to projects of any size, from the smallest site to a large e-commerce platform.
- Rapid Implementation: enabled by native TypeScript integration.
- Excellent User Experience: smooth and responsive, thanks to features like pre-rendering and code splitting.
At Brainy Labs we use Next.js on projects where indexing and performance genuinely matter — portals, platforms and high-traffic public areas. If you are weighing up the technology for your project, see how we approach web app and platform development.
Next.js is therefore an excellent React-based framework that leverages TypeScript, providing a set of innovative features designed to simplify and enhance the development of complex projects. If you have experience with these technologies, send us your resume! We're always looking for new talent to add to our team.
Frequently asked questions
What is the difference between React and Next.js?+
React is a library for building interfaces: it handles how components are rendered, not how the application is served. Next.js is a framework built on top of React that adds what React leaves out — routing, server-side rendering, static generation, serverless APIs and asset optimisation. With React you assemble that infrastructure yourself; with Next.js it is already decided and integrated.
Is Next.js really better for SEO?+
Yes, and the reason is technical: with server-side rendering (SSR) or static generation (SSG) the content reaches the crawler already inside the HTML, instead of being built by JavaScript after load. A traditional React application serves an almost empty page and fills it client-side, which makes indexing slower and less reliable. Next.js removes that problem.
When is Next.js the right choice, and when is it not?+
It is the right choice when the project needs to be indexed, has to handle traffic, or is meant to grow: portals, platforms, e-commerce, applications with both public and restricted areas. It makes less sense for an application entirely behind a login, where SEO is irrelevant and server-side rendering adds complexity without benefit — a classic single page application is often enough there.
Do you need TypeScript to work with Next.js?+
It is not mandatory, but the integration is native and on a project meant to last, static typing pays off quickly: it catches at compile time a class of errors that would otherwise surface in production. We use it on every project.
