Next.js Fullstack

Ship Next.js features with correct boundaries between server, client, data, and UI.

Grok Build Mode

• Use Plan Mode for routing, auth, persistence, caching, or data-fetching changes.
• Use subagents for broad changes:
  • routes: app router structure, layouts, metadata.
  • data: DB queries, server actions, validation.
  • client: components, state, forms, accessibility.
  • tests: unit/e2e/build verification.
• Arena-style comparison: compare server action vs API route vs client-only approaches and choose by security, simplicity, and cache behavior.

Workflow

1. Detect Next version, package manager, styling, auth, DB, and test setup.
2. Keep server-only code out of client components.
3. Validate inputs on the server.
4. Respect existing caching/revalidation patterns.
5. Add loading/error/empty states.
6. Run the narrowest relevant checks:
   • npm run lint
   • npm run typecheck
   • npm run build
   • project tests.

Rules

• Do not leak secrets into NEXT_PUBLIC_*.
• Avoid unnecessary client components.
• Do not mutate data without auth and ownership checks.
• Keep forms progressive and resilient.
• Use existing UI primitives and route conventions.

Example Prompts

Use nextjs-fullstack. Plan a server-action implementation for this feature, including validation, auth, tests, and loading/error UI.
