Vue 3 Development
Reference for Vue 3 Composition API patterns, component architecture, and testing practices.
Current stable: Vue 3.5+ with enhanced reactivity performance (-56% memory, 10x faster array tracking), new SSR features, and improved developer experience.
Overview
Progressive reference system for Vue 3 projects. Load only files relevant to current task to minimize context usage (~250 tokens base, 500-1500 per sub-file).
When to Use
Use this skill when:
- Writing
.vuecomponents - Creating composables (
use*functions) - Building client-side utilities
- Testing Vue components/composables
Use nuxt skill instead for:
- Server routes, API endpoints
- File-based routing, middleware
- Nuxt-specific patterns
For styled UI components: use nuxt-ui skill For headless accessible components: use reka-ui skill For VueUse composables: use vueuse skill
Quick Reference
| Working on... | Load file |
|---|---|
.vue in components/ | references/components.md |
File in composables/ | references/composables.md |
File in utils/ | references/utils-client.md |
.spec.ts or .test.ts | references/testing.md |
| TypeScript patterns | references/typescript.md |
| Vue Router typing | references/router.md |
Loading Files
Load one file at a time based on file context:
- Component work → references/components.md
- Composable work → references/composables.md
- Utils work → references/utils-client.md
- Testing → references/testing.md
- TypeScript → references/typescript.md
- Vue Router → references/router.md
DO NOT load all files at once - wastes context on irrelevant patterns.
Available Guidance
references/components.md - Props with reactive destructuring, emits patterns, defineModel for v-model, slots shorthand
references/composables.md - Composition API structure, VueUse integration, lifecycle hooks, async patterns, reactivity gotchas
references/utils-client.md - Pure functions, formatters, validators, transformers, when NOT to use utils
references/testing.md - Vitest + @vue/test-utils, component testing, composable testing, router mocking
references/typescript.md - InjectionKey for provide/inject, vue-tsc strict templates, tsconfig settings, generic components
references/router.md - Route meta types, typed params with unplugin-vue-router, scroll behavior, navigation guards
