React vs Next.js: Which Should You Choose?

Choosing between React and Next.js is one of the most common decisions developers face. While React is a library and Next.js is a framework built on React, they serve different use cases.

Understanding the Difference

React

React is a JavaScript library for building user interfaces. It's maintained by Meta and provides the core tools for creating component-based UIs.

Next.js

Next.js is a React framework created by Vercel that adds features like:

• Server-side rendering (SSR)
• Static site generation (SSG)
• File-based routing
• API routes
• Built-in optimization

When to Choose React

Choose React when:

• Building a single-page application (SPA)
• You need maximum flexibility
• Your team is already familiar with React
• You're building a mobile app with React Native

When to Choose Next.js

Choose Next.js when:

• SEO is important
• You need fast initial page loads
• You want built-in routing
• You need API endpoints
• You're building a marketing site or blog
