Next.js Tutorials
App Router, server components, caching, and production patterns for modern full-stack React apps.
Basic
App Router Basics
The file-system routing model where folders define routes and special files define UI for each segment.
Layouts And Pages
Compose shared UI with layouts while keeping route-specific content in focused page components.
Linking And Navigation
Build fast client-side navigation with Link, prefetching, and programmatic routing APIs.
Intermediate
Server Components
Default server rendering for smaller bundles, direct data access, and improved security boundaries.
Client Components
Interactive UI with hooks, browser APIs, and event handlers — scoped behind the client boundary.
Fetching Data
Server-first data access patterns with fetch caching, ORM queries, and loading UI integration.
Dynamic Routes
Build routes with dynamic segments, catch-all paths, and static generation at scale.
Forms And Server Actions
Handle mutations and form submissions with Server Actions, validation, and progressive enhancement.
Route Handlers
Build HTTP endpoints in the App Router for APIs, webhooks, and integrations.
Metadata And Open Graph Images
SEO metadata, social previews, and dynamic Open Graph image generation per route.
Images And Fonts Optimization
Deliver optimized images and stable typography with next/image and next/font.
Advanced
Streaming & Suspense
Stream HTML progressively with Suspense boundaries for faster perceived load and responsive UX.
Caching Strategies For Fast Next Apps
Control route and data caching for performance under real traffic and changing content.
Revalidating Data And Paths
Keep cached content fresh with time-based and on-demand revalidation strategies.
Error Handling And Recovery
Route-level error boundaries, not-found handling, and stable UX when things go wrong.
Authentication Patterns
Secure sessions, middleware guards, and auth integration patterns in Next.js App Router.
Middleware And Proxy Patterns
Shape requests early with middleware for auth, redirects, rewrites, and geolocation routing.
Deploying And Upgrading Next Apps
Ship safely to production and upgrade Next.js with confidence using disciplined release practices.
