When not to use Next.js
If your previous app was a simple, single HTML file, then you probably don’t need to use Next.js for that. That would be like using a tank to kill a mosquito when a clap of your hands could do the job.
If your app doesn’t require the advanced features that Next.js provides, such as server-side rendering, static site generation, or file-based routing, then you don’t need to use Next.js. It’s important to match the tool to the needs of your project. Using a feature-rich framework like Next.js on a basic, static website would be overkill.
