Foundational architecture for Nuxt 4 + Vue 3 + Nuxt UI applications. Use when starting new projects, understanding project structure, or making architectural decisions about directory organization, technology choices, and pattern selection.
Nuxt Architecture
Domain-driven, type-safe, composable-first architecture prioritizing separation of concerns.
Core Philosophy
philosophy.md - Foundational principles, separation of concerns, when to use each pattern
Project Structure
structure.md - Directory layout, naming conventions, file organization
Technology Stack
| Layer | Technology |
|---|---|
| Framework | Nuxt 4 (SPA mode, SSR disabled) |
| UI | Vue 3 Composition API |
| Components | Nuxt UI v4 + Tailwind CSS 4 |
| State | Composables with ref/useState |
| HTTP | Custom fetch via Sanctum/ofetch |
| Auth | Laravel Sanctum (nuxt-auth-sanctum) |
| Real-time | Laravel Echo (nuxt-laravel-echo) |

Pattern Flow
Component → Action → Mutation → Repository → API

Query (reactive data fetching)
Actions orchestrate business logic. Mutations handle pure API calls. Queries provide reactive data. Repositories abstract API access.

cache-components
Expert guidance for Next.js Cache Components and Partial Prerendering (PPR). **PROACTIVE ACTIVATION**: Use this skill automatically when working in Next.js projects that have `cacheComponents: true` in their next.config.ts/next.config.js. When this config is detected, proactively apply Cache Components patterns and best practices to all React Server Component implementations. **DETECTION**: At the start of a session in a Next.js project, check for `cacheComponents: true` in next.config. If enabled, this skill's patterns should guide all component authoring, data fetching, and caching decisions. **USE CASES**: Implementing 'use cache' directive, configuring cache lifetimes with cacheLife(), tagging cached data with cacheTag(), invalidating caches with updateTag()/revalidateTag(), optimizing static vs dynamic content boundaries, debugging cache issues, and reviewing Cache Component implementations.

component-refactoring
Refactor high-complexity React components in Dify frontend. Use when `pnpm analyze-component --json` shows complexity > 50 or lineCount > 300, when the user asks for code splitting, hook extraction, or complexity reduction, or when `pnpm analyze-component` warns to refactor before testing; avoid for simple/well-structured components, third-party wrappers, or when the user explicitly wants testing without refactoring.
