Why this lesson matters

Understand create a next.js project and use it correctly in an App Router project. Next.js adds routing, server rendering, data boundaries and production build behavior around React; understanding the project tree prevents framework conventions from feeling magical.

How to reason about it

  • For Create a Next.js Project, the outcome to verify is: Choose TypeScript and App Router for a new project so the course examples match.
  • In Create a Next.js Project, keep this failure controlled: Treating Next.js as client-only React leads to unnecessary browser JavaScript and server/client boundary mistakes.
  • Create a Next.js Project practice target: Create a fresh App Router project and identify which files own a page, layout, configuration and public asset.

Practical walkthrough

In the Create a Next.js Project walkthrough: Choose TypeScript and App Router for a new project so the course examples match.

  • Record the expected result before execution
  • Test one valid path and one lesson-specific failure path
  • Explain in two lines which boundary owns the decision
