Overview

This skill provides a compact, opinionated set of best practices for developing, refactoring, and reviewing Vue.js and Nuxt projects. It emphasizes predictable state, explicit data flow, focused components, and the Composition API with TypeScript-ready Single-File Components. Use it to guide architecture decisions, code reviews, and incremental refactors.

How this skill works

The skill inspects code and design choices against core principles: single source of truth for state, props-down/events-up data flow, and component responsibility boundaries. It enforces defaults such as Composition API and <script setup lang="ts"> SFCs, recommends splitting large components, and moves shared logic into composables or a store. It also ensures reactivity and data-flow patterns follow established guides for safe updates and predictable behavior.

When to use it

• Starting a new Vue or Nuxt project to set consistent conventions
• Refactoring large components into smaller, testable parts
• Performing code reviews focused on state, reactivity, and data flow
• Implementing cross-component state or shared logic with composables or a store
• Migrating Options API codebase toward Composition API and TypeScript

Best practices

• Keep one source of truth for state; derive values instead of duplicating them
• Prefer Composition API and <script setup lang="ts"> SFCs by default unless constrained
• Keep components small and single-responsibility; split UI and orchestration
• Move shared logic and side effects into composables (useXxx) and use a store for app-wide state
• Make data flow explicit: props down, emits/events up, use v-model for two-way bindings, provide/inject sparingly
• Use computed properties and watchers appropriately to avoid unnecessary re-renders

Example use cases

• Split a dashboard component into data-fetching composable + presentational child components
• Refactor form logic into a useForm composable and keep inputs as focused child components
• Review a PR to ensure props/emits are used instead of global mutable state
• Migrate a small app from Options API to Composition API with TypeScript SFCs
• Introduce a centralized store for authenticated user state and derive read-only views with getters
