• Teams adopting React Server Components in production

Learning Outcomes

After completing this training, participants will be able to:

• Architect applications using the App Router's full feature set
• Implement advanced routing patterns including parallel and intercepting routes
• Design optimal server/client component boundaries
• Build streaming UIs with Suspense and progressive rendering
• Implement caching, revalidation, and Incremental Static Regeneration
• Handle complex data fetching scenarios with composition patterns

Detailed Agenda

Day 1: Advanced Routing

Module 1: App Router Deep Dive

• Route segments and conventions
• Dynamic segments, catch-all, and optional catch-all routes
• Route groups for organizational flexibility
• Hands-on: Build a multi-section application with route groups

Module 2: Parallel and Intercepting Routes

• Parallel routes with slots
• Conditional rendering with parallel routes
• Intercepting routes for modals
• Hands-on: Build a photo gallery with modal intercepts

Module 3: Navigation and Linking

• Link component and programmatic navigation
• Active link detection
• Scroll restoration and shallow routing
• Hands-on: Implement complex navigation with breadcrumbs

Day 2: Server Components Mastery

Module 4: Server Component Architecture

• React Server Components model
• Server vs client component rendering
• Serialization boundaries and constraints
• Hands-on: Architect a component tree with optimal boundaries

Module 5: Data Fetching Patterns

• Async Server Components for data fetching
• Request memoization and deduplication
• Parallel vs sequential data fetching
• Hands-on: Implement a dashboard with parallel data loading

Module 6: Streaming and Suspense

• Streaming Server Rendering
• Suspense boundaries for progressive loading
• Loading UI with loading.js conventions
• Hands-on: Build a streaming dashboard with skeleton loaders

Day 3: Caching and Advanced Patterns

Module 7: Caching Strategies

• Full Route Cache and Data Cache
• Cache invalidation with revalidatePath and revalidateTag
• Time-based and on-demand revalidation
• Hands-on: Implement multi-layer caching for a content site

Module 8: Incremental Static Regeneration

• Static and dynamic rendering modes
• ISR configuration and patterns
• generateStaticParams for static generation
• Hands-on: Build an ISR-powered blog with on-demand revalidation

Module 9: Error Handling and Edge Cases

• Error boundaries with error.js
• Not-found handling with not-found.js
• Global error handling patterns
• Hands-on: Implement comprehensive error handling across routes

Prerequisites

• Next.js Fundamentals or equivalent experience
• Strong React knowledge (hooks, context, component patterns)
• Understanding of server-side rendering concepts
• Familiarity with async/await and Promises
