✅ Routing and Page Management
How
Dynamic routing – Supports dynamic paths
(e.g., /post/[id]).
Middleware – Allows you to run logic in the router before the request reaches the page (e.g., auth or redirects)
Nested layouts (App Router) – Enables complex page structures with state preservation between navigations.
File-based routing – Each file in the /app or /pages directory automatically creates a route.
⚡ Rendering and Performance
How
Static site generation (SSG) – Lets you pre-build static pages.
Streaming & Partial rendering (React Server Components) – Enables progressive loading of components.
Incremental static regeneration (ISR) –
Re-renders specific pages at runtime without rebuilding the whole site.
Server-side rendering (SSR) - Fast loading and SEO-friendly.
🌐 SEO and Accessibility
How
Internationalization (i18n) –
Built-in support for multiple languages
and routing by locale.
Head management –
Simple way to manage titles, meta tags, etc.
via <Head>.
🧩 Convenient Integration and Configuration
How
Built-in TypeScript support –
No need for extra setup.
Zero-config –
Works out of the box with minimal setup.
API routes –
Enables server-side code (backend) within your app.
🛠️ Developer Tools
How
Built-in ESLint – Static checks.
Hot Module Replacement (HMR) –
Instant refresh while coding.
SWC compiler – faster compilation.
Preview Mode – Preview ISR pages before publishing.
🧠 Advanced React Development
How
React Server Components –
Allows logic to run on the server without
sending JavaScript to the client.
Full support for React 19 –
Includes Server Actions, useFormState, and more.
🎨 Image and Asset Optimization

📦 Ecosystem Integration
How
MDX support – Combine Markdown with JSX.
Styling libraries and integrations
(CSS Modules, Sass, Styled Components, Tailwind, and others).
Easy integration with external CMS or eCommerce platforms – Using API routes and smart data fetching.
🚀 Deployment & Hosting
How
Optimized for Vercel – Automatic deployments and scalable infrastructure. Best integration.
Other vendors support Next.js as well
(Fly.io, Netlify, Render, aws, gcp, Azure).
Edge functions –
Run code at the network edge, closer to users.
(Vercel has the best support. Others have partial variations.
