# vue-claude-stack

This rule guides code generation for Vue 3 and Nuxt 3, covering Composition API, TypeScript, and Pinia. Use it to give an agent consistent project conventions.

## What it does

The rule targets files matching `**/*` and sets conventions for Vue and Nuxt. It directs the agent to use Composition API with `<script setup lang="ts">`, typed props and events, and composables for reactive logic. Options API, `any`, and `v-html` with user input are disallowed. These rules shape both new components and code changes.

For Pinia, it calls for setup stores and `storeToRefs()` when unpacking state. Nuxt guidance covers `useFetch` or `useAsyncData`, file-based routes, and server handlers under `server/api/`. Tests use Vitest and `@vue/test-utils`, with test files beside their source. Check your Vue version: the `defineModel()` guidance is for Vue 3.4+.

The metadata sets `globs: **/*` and `alwaysApply: false`. In Cursor, place the rule at `.cursor/rules/vue-claude-stack.mdc`.

## Install

### Cursor (native platform)

**Manually: put the files in place**
- File: `.cursor/rules/vue-claude-stack.mdc` — Frontmatter: description, globs, alwaysApply

### Claude Code

**Manually: put the files in place**
- File: `.claude/rules/vue-claude-stack.md` — The paths frontmatter field limits the files: move globs from the source into paths

### Codex

**AGENTS.md**
- Codex reads AGENTS.md: paste the rule text there

### GitHub Copilot

**Manually: put the files in place**
- File: `.github/instructions/vue-claude-stack.instructions.md` — The applyTo field sets which files it applies to: move globs from the source into applyTo

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/rules/vue-claude-stack.md`

### Cline

**Manually: put the files in place**
- File: `.clinerules/vue-claude-stack.md`

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/PatrickJS/awesome-cursorrules/tree/HEAD/rules/vue-claude-stack.mdc

## When to use it
- guide component generation toward Composition API
- add types to props, events, and Pinia state
- structure Nuxt data fetching for SSR
- set conventions for Vue component tests
- avoid `v-html` with user-provided content

## Example prompts
- Create a Vue component with `<script setup lang="ts">` and typed props.
- Add a Pinia setup store and use `storeToRefs()` for its state.
- Write a colocated test with Vitest and `@vue/test-utils`.

You are an expert Vue 3 and Nuxt 3 developer with deep knowledge of TypeScript, Pinia, VueUse, Tailwind CSS, and the Vue ecosystem.

## Core Principles
- Always use Vue 3 Composition API with `<script setup lang="ts">`
- Never use Options API, mixins, or `this` keyword in setup
- Write TypeScript with strict mode — no `any`
- Follow Vue style guide priority A and B rules
- Prefer composables over utility functions for reactive logic

## Component Rules
- Use `defineProps<T>()` with TypeScript generics for props
- Use `defineEmits<T>()` with typed events
- Use `defineModel()` for v-model bindings (Vue 3.4+)
- Keep templates clean — extract complex logic to computed or composables
- One component per file, filename matches component name in PascalCase

## State Management (Pinia)
- Use setup stores with `defineStore('name', () => { ... })`
- Use `storeToRefs()` when destructuring store state
- Keep stores small and focused — one domain per store
- Never access store state directly in templates, use computed

## Composables
- Prefix with `use` (useAuth, useCart, useSearch)
- Accept `MaybeRef<T>` for flexible inputs
- Return `{ data, error, loading }` pattern for async composables
- Place in `composables/` directory for Nuxt auto-import

## Nuxt Specifics
- Use `useFetch` / `useAsyncData` for data fetching (SSR-compatible)
- Use file-based routing in `pages/`
- Use `definePageMeta()` for route metadata
- Server routes go in `server/api/`
- Use `createError()` for error handling

## TypeScript
- Define interfaces in `types/` directory
- Use `type` over `interface` unless extending
- Use `satisfies` operator for type checking
- No type assertions (`as`) unless absolutely necessary

## Testing
- Vitest + @vue/test-utils
- Test files next to source: `*.test.ts`
- Test behavior, not implementation
- Use `mount()` over `shallowMount()`

## Tailwind CSS
- Use utility classes directly in templates
- Extract repeated patterns to components, not CSS classes
- Use `@apply` sparingly — only in base styles
- Dark mode: use `dark:` variant

## Do NOT
- Generate Options API code
- Use `any` type — use `unknown` and narrow
- Put business logic in components
- Skip TypeScript on any file
- Use `v-html` with user input
- Mutate props
- Use `var` — always `const` or `let`
```
