# vue3

A Cursor rule that pins down how the agent writes Vue 3: Composition API, TypeScript, ESLint and Prettier. Useful when more than one person touches the codebase.

## What it does

The rule spells out a baseline set of conventions for Vue 3 apps. The agent follows them while generating or editing code, so component naming, file layout and tooling stay the same across the project.

Two sections sit inside. The first covers linting and formatting: ESLint paired with Prettier, wired into the IDE for feedback as you type and format-on-save. The second covers code organisation. Every component gets its own `.vue` file, and filenames use PascalCase, which matches how components are referenced in templates and helps editor autocompletion.

You drop the rule in as `.cursor/rules/vue3.mdc`, and it applies to files matching `**/*.{js,jsx,ts,tsx,vue}`. Without ESLint and Prettier already configured in the project, some of the guidance stays theoretical — the agent will point at tools your build does not run.

## Install

### Cursor (native platform)

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

### Claude Code

**Manually: put the files in place**
- File: `.claude/rules/vue3.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.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.md`

### Cline

**Manually: put the files in place**
- File: `.clinerules/vue3.md`

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/sanjeed5/awesome-cursor-rules-mdc/tree/HEAD/rules-mdc/vue3.mdc

## When to use it
- keep code style consistent across a team
- split Vue components into separate files
- rename `.vue` files to PascalCase
- hook ESLint and Prettier into the editor
- write typed components with the Composition API

## Example prompts
- Create a `TodoList.vue` component using the Composition API with types
- Split this component into separate `.vue` files following the project rules
- Rename the component files to PascalCase and fix the imports

# Vue 3 Best Practices

This guide outlines the essential rules for developing high-quality Vue 3 applications. Adhere to these standards to ensure consistency, readability, and long-term maintainability across our codebase.

## 1. Foundational Setup: Linting & Formatting

**Always use ESLint and Prettier.** This combination enforces consistent code style and catches common errors automatically, streamlining development and code reviews. Integrate them into your IDE for real-time feedback and format-on-save.

## 2. Code Organization & Naming

### 2.1. Single-File Components (SFCs)
Each component **must** reside in its own `.vue` file.

❌ BAD
```js
// app.component('TodoList', { /* ... */ })
// app.component('TodoItem', { /* ... */ })
```

✅ GOOD
```
components/
├── TodoList.vue
└── TodoItem.vue
```

### 2.2. SFC Filename Casing
Use **PascalCase** for all SFC filenames. This aligns with component referencing in templates and JS(X) and improves editor autocompletion.

❌ BAD
```
components/
├── my-component.vue
└── myComponent.vue
```
