After working with various frameworks — plain React, Vue, and even server-rendered PHP — I've settled on Next.js as my primary tool for building web applications. Here's why, and what I've learned from shipping multiple projects with it.
Performance Out of the Box
Next.js gives you automatic code splitting, image optimization, and font optimization without any configuration. For my portfolio alone, switching to Next.js Image components and enabling WebP/AVIF conversion reduced image payload by over 7MB. That's a massive win for users on mobile networks in Kenya where data costs matter.
SEO That Actually Works
Unlike traditional React SPAs, Next.js renders HTML on the server (or at build time), meaning search engines can crawl your content immediately. For my Icon Tech e-commerce project, this meant product pages were indexed within days of deployment. The built-in metadata API makes managing Open Graph tags, structured data, and sitemaps straightforward.
The Developer Experience
File-based routing, API routes, middleware, and the App Router — Next.js keeps getting better with each release. The new React Server Components let me fetch data directly in components without useEffect or client-side loading states. It feels like the future of React development.
- File-based routing eliminates the need for react-router configuration
- API routes let you build full-stack apps in one project
- Built-in image and font optimization saves hours of manual work
- Server Components reduce client-side JavaScript significantly
When NOT to Use Next.js
Next.js isn't the answer for everything. For simple static sites with no dynamic content, a plain HTML/CSS approach might be faster to ship. For complex real-time applications like chat apps, you might want a dedicated backend framework. But for 90% of web projects I encounter — portfolios, e-commerce, dashboards, blogs — Next.js is the right choice.
