Syllabus

25 lessons across chapters
1

Module 1: Modern App Router Architecture & Async Request Context

6 lessons

  1. Lesson 1

    Next.js 16 & React 19 Setup

    Configure Next.js 16 projects with TypeScript, Turbopack, and strict build configurations.

  2. Lesson 2

    App Router Hierarchy & Colocation

    Analyze the modern App Router file-system hierarchy, special files, and colocation patterns.

  3. Lesson 3

    Async Request Parameters & Context

    Implement async request APIs to safely access route `params` and `searchParams`.

  4. Lesson 4

    Dynamic Runtime APIs & Boundaries

    Isolate dynamic runtime APIs like `cookies()` and `headers()` to prevent accidental route-wide degradation.

  5. Lesson 5

    Layouts, Templates, & Error Boundaries

    Configure root and nested layouts with parallel data loading patterns and error boundaries.

  6. Lesson 6

    Parallel & Intercepting Routes

    Implement parallel routes and intercepting routes for advanced modal and dashboard workflows.

2

Module 2: Cache Components & The `use cache` Paradigm

5 lessons

  1. Lesson 7

    The Cache Components Paradigm

    Transition from implicit caching models to the unified Cache Components model in Next.js 16.

  2. Lesson 8

    Implementing the `'use cache'` Directive

    Apply the `'use cache'` directive to asynchronous functions and granular UI components.

  3. Lesson 9

    Cache Lifecycles & Revalidation Tags

    Configure explicit cache expiration profiles using `cacheLife` and granular invalidation tags with `cacheTag`.

  4. Lesson 10

    Isolating Request State from Cached Scopes

    Isolate request-specific state from cached scopes to avoid shared-state corruption.

  5. Lesson 11

    Programmatic Cache Invalidation

    Handle cache purge workflows and programmatic revalidation in server actions.

3

Module 3: Partial Prerendering (PPR) & Streaming Architecture

4 lessons

  1. Lesson 12

    Partial Prerendering Architecture

    Architect high-performance hybrid applications combining static shells with dynamic data streams.

  2. Lesson 13

    Suspense Boundaries & Streaming UI

    Implement React `<Suspense>` boundaries to stream granular dynamic content chunks.

  3. Lesson 14

    Loading States & Fallback UX

    Optimize loading states and fallback UI components for zero layout shifts.

  4. Lesson 15

    Route Segment Config & PPR Tuning

    Configure dynamic segment caching and route segment config options for PPR.

4

Module 4: Server Actions & React 19 State Mutations

6 lessons

  1. Lesson 16

    React 19 Actions & Mutation Fundamentals

    Analyze React 19 action primitives and seamless client-to-server data mutations.

  2. Lesson 17

    Form State Management with `useActionState`

    Construct resilient forms using `useActionState` for pending states and error handling.

  3. Lesson 18

    Form Status Tracking with `useFormStatus`

    Track submission lifecycle events using `useFormStatus` inside nested client components.

  4. Lesson 19

    Optimistic Updates with `useOptimistic`

    Implement optimistic UI updates with `useOptimistic` for instant feedback during mutations.

  5. Lesson 20

    Server-Side Payload Validation & Zod

    Validate server action payloads securely using Zod schemas and type guards.

  6. Lesson 21

    Authentication & Session Cookies in Actions

    Manage secure HTTP-only cookies and session tokens inside server actions.

5

Module 5: Production Optimization, Security, & Edge Deployment

4 lessons

  1. Lesson 22

    React Compiler Integration

    Leverage the React Compiler to eliminate manual memoization (`useMemo`, `useCallback`).

  2. Lesson 23

    Security Headers & Edge Middleware

    Configure Content Security Policy (CSP), headers, and secure middleware routing.

  3. Lesson 24

    Asset Optimization & Core Web Vitals

    Configure bundle analyzer, image optimization, and font loaders for peak web vitals.

  4. Lesson 25

    Production Deployment & Edge Routing

    Deploy production-ready Next.js 16 applications to Vercel and serverless edge environments.
