Why this lesson matters

Understand what next.js adds to react 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 What Next.js Adds to React, the outcome to verify is: Keep the example small so the concept is visible without unrelated details.
  • In What Next.js Adds to React, keep this failure controlled: Treating Next.js as client-only React leads to unnecessary browser JavaScript and server/client boundary mistakes.
  • What Next.js Adds to React practice target: Create a fresh App Router project and identify which files own a page, layout, configuration and public asset.

Practical walkthrough

  • 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
