From MERN to Next.js: My Journey as a Full Stack Developer

Hi everyone 👋 I'm a Full Stack Developer with experience in JavaScript, React.js, Next.js, Node.js, Express.js, MongoDB, and WordPress development. Over the last few years, I have worked on multiple projects ranging from company websites to full-stack web applications. In this article, I want to share my experience transitioning from the traditional MERN stack to Next.js and why it has become my preferred framework for modern web development. Why I Started with MERN Stack The MERN stack was my first choice because it allowed me to build complete applications using JavaScript. Technologies MongoDB Express.js React.js Node.js Benefits ✅ Single language across frontend and backend ✅ Huge ecosystem ✅ Fast development ✅ Easy API integration Challenges I Faced As projects became larger, I started facing issues like: SEO limitations Performance optimization Routing complexity Code organization Server-side rendering requirements This is where Next.js entered the picture.
