Domain model classes with automatic hydration, relations, and type casting. Use when creating models for API entities, defining relationships between models, casting properties to enums/dates, or creating value objects.
Nuxt Models
Type-safe domain models with automatic hydration, relations, and property casting.
Core Concepts
models.md - Complete model patterns, lifecycle, relations, casts
values.md - Value objects for typed wrappers (DateValue, etc.)
Basic Model
// app/models/Post.ts
import Model from '#layers/base/app/models/Model'
import type { Castable } from '#layers/base/app/types'
import PostStatus from '~/enums/PostStatus'
import DateValue from '~/values/DateValue'
import Author from '~/models/Author'
export default class Post extends Model {
ulid: string
title: string
content: string
status: PostStatus
isDraft: boolean
author: Author
createdAt: DateValue
public override primaryKey(): string {
return 'ulid'
}
public override casts(): Record<string, Castable> {
return {
status: PostStatus,
createdAt: DateValue,
}
}
public override relations(): Record<string, typeof Model> {
return {
author: Author,
}
}
public isPublished(): boolean {
return !this.isDraft
}
}
Model Lifecycle
API Response → booting() → transform() → Property Assignment
→ Relations Hydrated → Casts Applied → booted() → Ready
Usage
// Hydrate from API response
const post = Post.hydrate(apiResponse.data)
// Hydrate collection
const posts = Post.collect(apiResponse.data)
// Access typed properties
post.status.color() // Enum method
post.createdAt.format() // Value object method
post.author.name // Relation property
// Compare models
post.is(otherPost) // Same primary key?

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.

web-artifacts-builder
Suite of tools for creating elaborate, multi-component claude.ai HTML artifacts using modern frontend web technologies (React, Tailwind CSS, shadcn/ui). Use for complex artifacts requiring state management, routing, or shadcn/ui components - not for simple single-file HTML/JSX artifacts.
anthropicsfrontend-design
Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, artifacts, posters, or applications (examples include websites, landing pages, dashboards, React components, HTML/CSS layouts, or when styling/beautifying any web UI). Generates creative, polished code and UI design that avoids generic AI aesthetics.
