Exploring Various Coding Languages
Next.js provides powerful tools for defining metadata and Open Graph (OG) images to improve SEO and social sharing. This article explains how to use static and dynamic metadata, special files like favicon and opengraph-image, and generate OG images using JSX and CSS with ImageResponse.
Route Handlers in Next.js allow you to define custom HTTP request handlers directly within the app directory. This article explains how to create route.ts files, use supported HTTP methods like GET and POST, leverage NextRequest and NextResponse, control caching, and type route parameters using RouteContext.
Proxy in Next.js allows you to intercept and modify requests before they complete. This article explains how to use proxy.ts to perform redirects, rewrites, and header modifications based on incoming requests. It also outlines best practices, limitations, and how to configure path matching for route-specific proxy logic.
Next.js can be deployed as a Node.js server, Docker container, static export, or adapted to platform-specific infrastructure. This article explains each deployment method, feature support, development tips, and how to upgrade to the latest or canary versions of Next.js..
Next.js offers built-in tools for measuring performance and reporting analytics. This article explains how to use the useReportWebVitals hook, set up instrumentation-client for global tracking, and send metrics to external services like Google Analytics or custom endpoints.
Authentication in Next.js involves verifying user identity, managing sessions, and controlling access to routes. This article walks through building a secure sign-up form using Server Actions and useActionState, validating fields with Zod, and creating user accounts with hashed passwords. It also highlights best practices and tips for improving user experience.
Session management in Next.js ensures that a user's authenticated state persists across requests. This article explains how to create, store, refresh, and delete sessions using stateless cookies or database-backed sessions. It covers JWT encryption with Jose, secure cookie settings, and best practices for performance and security.
Once a user is authenticated, authorization in Next.js determines what routes and data they can access. This article explains optimistic and secure checks, using Proxy for early redirects, building a centralized Data Access Layer (DAL), applying Data Transfer Objects (DTOs), and rendering components based on user roles in Server Components.
In Next.js, Server Actions and Route Handlers must be treated with the same security considerations as public API endpoints. This article explains how to verify user roles before mutations, enforce access control in Route Handlers, understand the limitations of context providers in Server Components, and explore recommended libraries for secure authentication and session management.
Next.js allows you to receive external events via webhooks and callback URLs. This article explains how to build Route Handlers to process events, perform redirects, proxy requests, and implement robust security practices including header control, rate limiting, payload validation, and access protection.
Next.js supports the Backend for Frontend (BFF) pattern, allowing you to create public endpoints that handle HTTP requests and return any content type. This article explains how to use Route Handlers, Proxy, and API Routes to build a secure and flexible backend layer for your frontend, including examples for data transformation, request validation, and content delivery.
Next.js uses intelligent caching to boost performance and reduce server costs. This article explores the different caching mechanisms in Next.js, how rendering strategies affect them, and how to control caching behavior using built-in APIs like fetch, revalidatePath, and router.prefetch..
