## What it does

The rule covers Vue 3 component logic with `setup()`, reactive state using `ref` and `reactive`, and derived values through `computed()`. It points to `watch` and `watchEffect` for side effects, plus lifecycle hooks such as `onMounted` and `onUpdated`. It also covers `provide`/`inject`, TypeScript, and definitions for props and emits.

A suggested `src/` layout includes `components/`, `composables/`, `views/`, `router/`, `store/`, and `assets/`, alongside `App.vue` and `main.js`. The rule matches `**/*`, while `alwaysApply` is set to `false`, so it is not configured to apply all the time. Other guidance covers error handling, Vue 3 naming and style conventions, and using Vite, `Teleport`, or `Suspense` where appropriate.

## Install

### Cursor (native platform)

**Manually: put the files in place**
- File: `.cursor/rules/vue3-composition-api-cursorrules-prompt-file.mdc` — Frontmatter: description, globs, alwaysApply

### Claude Code

**Manually: put the files in place**
- File: `.claude/rules/vue3-composition-api-cursorrules-prompt-file.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/vue3-composition-api-cursorrules-prompt-file.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/vue3-composition-api-cursorrules-prompt-file.md`

## When to use it
- structure Vue 3 component logic around `setup()`
- choose Vue 3 APIs for reactive state and side effects
- organize a project with a suggested `src/` layout
- define typed props and emits for components

## Example prompts
- Create a Vue 3 component with the Composition API and typed props and emits.
- Add reactive state and a computed value to this component.
- Organize this Vue 3 project using the suggested `src/` layout.
