The paper "Building High-Performance Web Applications with NextJS" by Harrison Oke Ekpoobimi explores the key strategies and techniques for optimizing performance using the NextJS framework. NextJS, built on React, is highlighted for its robust features in static site generation (SSG), server-side rendering (SSR), and incremental static regeneration (ISR). The paper discusses how NextJS simplifies code splitting and lazy loading, enhances image optimization, and supports various data-fetching methods to cater to different performance needs. It also emphasizes the importance of Progressive Web App (PWA) features, such as offline support and caching, to improve user experience and application resilience. Advanced performance techniques, including custom Webpack configurations, integration with Content Delivery Networks (CDNs), and the use of NextJS plugins and middleware, are covered to further enhance application performance. The paper concludes by discussing the importance of continuous monitoring and maintenance through tools like Lighthouse, real user monitoring, and automated CI/CD pipelines to ensure sustained performance and reliability. Case studies from Netflix Jobs, Twitch, and HashiCorp illustrate the practical application of NextJS in high-performance web development.The paper "Building High-Performance Web Applications with NextJS" by Harrison Oke Ekpoobimi explores the key strategies and techniques for optimizing performance using the NextJS framework.
