Modern frontend development combining React as UI library with Next.js as full-stack framework. Architecture based on Server Components, App Router, Server Actions, and hybrid rendering (SSR, SSG, ISR) for production-ready applications.
Modern React with Server Components, Suspense and advanced hooks (useActionState, use)
Next.js App Router with layouts, streaming SSR and partial prerendering
Server Actions for server-side mutations without API routes
Strict TypeScript with type inference and type safety
File-based routing with dynamic routes and route groups
Modern data fetching (fetch with cache, Server Components, parallel data)
State management (Context API, Zustand, TanStack Query for server cache)
Styling with TailwindCSS, CSS Modules, styled-components or Sass
Comprehensive testing (Vitest/Jest, React Testing Library, Playwright/Cypress)
Performance (Image/Font optimization, code splitting, lazy loading, analytics)
The most important concepts to understand this technology and ace your interviews
React: JSX, Virtual DOM, reconciliation, fiber architecture
Modern hooks: useState, useEffect, useContext, useMemo, useCallback, useActionState
Server Components vs Client Components ("use client"), composition patterns
Props, State, lifting state up, prop drilling and solutions
React lifecycle, useEffect cleanup, dependency array, strict mode
Next.js App Router: routing, layouts, templates, loading/error states
Data fetching: async Server Components, fetch caching, revalidation strategies
Server Actions: progressive enhancement, useActionState, form handling
Rendering strategies: SSR, SSG, ISR, client-side, streaming
State management: Context API, Zustand, Redux Toolkit, server state (TanStack Query)
Performance: React.memo, useMemo, useCallback, lazy loading, Suspense boundaries
Routing: dynamic routes, parallel routes, intercepting routes, middleware
Metadata and SEO: generateMetadata, sitemap, robots.txt, Open Graph
Testing: component tests, integration tests, E2E, mocking, test patterns
Build optimization, bundle analysis, deployment (Vercel, Docker), monitoring
