Testing and error handling patterns in Next.js

Next.js, a popular framework built on React, simplifies the process of developing scalable applications and provides robust testing and error handling capabilities. Testing in Next.js can be accomplished using libraries like Cypress, Jest, and React Testing Library, which allow developers to write efficient code and save time on debugging. Error handling is enhanced through Next.js APIs that enable graceful error management, ensuring a better user experience by redirecting users to custom error pages. Next.js supports three types of errors: development runtime errors that appear as overlays in the development server, client errors handled through the React Error Boundary API, and server errors managed within data-fetching methods like getStaticProps and getServerSideProps. The framework allows for the customization of error pages, such as 404 and 500 pages, to improve error handling and user experience. Additionally, tools like LogRocket provide comprehensive monitoring and debugging capabilities for Next.js applications, capturing errors, network requests, and user sessions to facilitate seamless problem-solving.
