You worked through Next.js App Router fundamentals: file conventions, server/client boundaries, data and cache patterns, forms, deployment, and production habits. The goal was a mental model for real full-stack React apps—not every config flag.
What you should be able to do now
- Map folders under
app/to URLs and special files - Choose Server vs Client Components and place
'use client'deliberately - Fetch on the server, cache/revalidate thoughtfully, and add loading/error UI
- Explain Server Actions, Route Handlers, middleware, and deployment basics in interviews
Suggested next steps
- Run
npx create-next-app@latestlocally and recreate one lesson route. - Revisit React hooks for complex client islands.
- Deploy a demo to Vercel or Docker with env vars configured.
- Re-run MCQs until you score comfortably on caching and RSC questions.
Keep practicing
Framework details evolve—anchor on boundaries (server/client), caching semantics, and file conventions; official Next.js docs fill in version-specific API changes.
Self-check
- Which lesson was hardest—and what will you rebuild locally?
- What app will you ship next with Next.js?
Challenge
Mini capstone plan
- Sketch routes: home, blog/[slug], dashboard (protected).
- Label server vs client for each segment.
- Start a local create-next-app project matching your sketch.
Done when: you have a route diagram and a started local project.
