About this course
A complete, step-by-step introduction to Next.js fullstack engineering designed for absolute beginners. Master the App Router mental model, React Server Components (RSC), Client Components, nested layouts, dynamic routes ([slug]), metadata for SEO, streaming with React Suspense, error handling with error.tsx, data mutations using Server Actions, Zod validation, optimistic UI, REST APIs with route.ts, Edge Middleware guards, and fullstack authentication with Firebase and Supabase — building 5 progressive fullstack projects culminating in a production SaaS platform.
What you'll learn
- Understand why fullstack engineering shifted to Next.js: Server-Side Rendering (SSR), Static Site Generation (SSG), and Hydration
- Build and compose applications using the App Router, special files (layout, page, loading, error, not-found), and dynamic segments ([slug])
- Master React Server Components (RSC) to ship zero-bundle-size server code while isolating client interactivity with "use client"
- Stream slow data progressively using loading.tsx and React Suspense boundaries to eliminate blank screens
Prerequisites
- Basic knowledge of React components and modern JavaScript (ES6+). Every Next.js concept is explained step by step for beginners!
