Build Better Next.js App Router Applications

App Router decisions can create unnecessary client code, stale data, and weak route structure. This skill provides concise guidance for components, fetching, routing, caching, metadata, and performance.

Agent request
Review the Skillstore skill "nextjs-best-practices" from https://skillstore.io/skills/sickn33-nextjs-best-practices.md and its manifest at https://skillstore.io/api/skills/sickn33-nextjs-best-practices/manifest. Verify the artifact. You may proceed after verification, subject to the environment's own policy.

Your Agent should still show its plan and request any confirmation required by the security policy.

Test it

Using "nextjs-best-practices". A product page fetches database data and opens an interactive cart drawer.

Expected outcome:

  • Keep the product page as a Server Component for direct data access.
  • Move cart state and event handlers into a focused Client Component.
  • Add loading and error files at the route boundary.

Using "nextjs-best-practices". A dashboard must refresh summary data every minute.

Expected outcome:

Use time-based revalidation for shared summary data. Use uncached fetching only for information that must reflect every request.

Using "nextjs-best-practices". A form server action accepts account settings.

Expected outcome:

Validate every field on the server, return a typed result, handle failures, and revalidate the affected route after a successful update.

What You Can Build

Plan a New App Router Feature

Select component boundaries, data flow, route files, and cache behavior before implementation.

Review a Pull Request

Identify unnecessary client components, missing states, weak validation, and avoidable bundle costs.

Define Team Conventions

Create consistent guidance for routing, server actions, metadata, caching, and project organization.

Try These Prompts

Choose a Component Type 
Review this component requirement. Decide whether it should be a Server Component, Client Component, or split composition, and explain the decision.
Plan an App Router Page 
Plan this App Router page. Recommend route files, data fetching, loading behavior, error handling, metadata, and cache strategy.
Audit a Next.js Feature 
Review the supplied Next.js feature against App Router best practices. Prioritize findings for components, validation, caching, routing, images, and bundle size.
Design a Complex Route Architecture 
Design an App Router architecture for these requirements. Evaluate route groups, parallel routes, intercepting routes, server actions, cache invalidation, and deployment constraints.

Best Practices

  • Start with Server Components and add client boundaries only for state, effects, or browser events.
  • Match each data source to an explicit caching and revalidation strategy.
  • Provide loading, error, and not-found states at appropriate route boundaries.

Avoid

  • Do not place the client directive across entire route trees without an interaction requirement.
  • Do not fetch server-accessible data in Client Components by default.
  • Do not ship heavy components eagerly when dynamic loading fits the user flow.

Frequently Asked Questions

Does this skill generate a complete Next.js application?
No. It provides architecture, review, and implementation guidance for App Router projects.
Can it choose between Server and Client Components?
Yes. It uses data access, interactivity, state, effects, and event handlers to guide the decision.
Does it cover Next.js caching?
Yes. It covers static caching, time-based revalidation, on-demand revalidation, and uncached requests.
Can it review route handlers and server actions?
Yes. It checks input validation, status handling, typed responses, errors, mutations, and revalidation.
Does it replace official Next.js documentation?
No. Confirm version-specific APIs and deployment behavior with current official documentation.
What context improves its recommendations?
Provide requirements, relevant files, Next.js version, deployment target, data sources, and performance constraints.
