How does Next.js routing work?

Next.js uses file-based routing. Files in pages directory become routes. Dynamic routes use [param] syntax.

Routing is automatic and intuitive.

Frequently asked questions

What is Next.js and why should I use it?

Next.js is a React framework that provides server-side rendering, static site generation, API routes, and various optimizations to help you build fast and scalable web applications.

How do I handle API routes in Next.js?

You create API routes by placing JavaScript files within the `pages/api` directory. These files are automatically mapped to URL paths, allowing you to build backend functionality for your Next.js application.

Are API routes serverless functions in pages/api directory?

Yes, API routes within the `pages/api` directory function as serverless functions, offering scalability and cost-effectiveness for handling backend logic without managing servers directly.

How do API routes simplify full-stack development alongside frontend?

API routes streamline full-stack development by allowing you to build the backend components – such as data fetching, authentication, and business logic – directly within your Next.js project, simplifying the overall architecture.
