Build Production-Grade Web Apps with Next.js 15
Next.js 15 is the React framework used in production by companies at every scale — it ships the App Router, Server Actions, and Partial Prerendering as first-class primitives, letting a single codebase handle routing, data fetching, authentication, and deployment without reaching for a separate backend. This track covers all of it, from your first file-based route to operating a multi-tenant SaaS at scale.
What You Will Learn
You will build with the App Router from the ground up, distinguish Client and Server Components and know when to use each, write Route Handlers and edge-ready API endpoints, and handle forms with validation and optimistic UX. Data fetching, caching, and revalidation internals are covered in depth alongside Server Actions, database integration, and authentication and authorization. Later courses address streaming UI with Suspense and Partial Prerendering, internationalization and localized routing, real-time apps with WebSockets, observability and error boundaries, and bundle optimization via the build pipeline.
The Learning Path
Twenty-two courses progress from A1 through C2. The track opens with Next.js 15 Foundations and App Router Essentials, builds through B1 and B2 with Testing Next.js Applications, Caching & Revalidation Internals, and Deployment & Real-world Project, then advances at C1 into Advanced Server Actions, Performance & Optimization, and Real-Time Apps with Streaming & WebSockets. The track closes at C2 with Multi-Tenant SaaS Architecture and Build Pipeline & Bundle Optimization.
How It Works
Each course is split into short, hands-on lessons you complete in the built-in editor with real-time feedback and an AI tutor available when you get stuck. All code runs against real Next.js 15 — no sandboxed toy environment.
