Is TypeScript required for Vue Expert JS?

No. This skill uses JavaScript only and relies on JSDoc for type hints.

How should I document props in a JS Vue component?

Document with JSDoc @typedef for complex props and @param/@returns for functions; prefer explicit types in comments.

Do I need to configure Vitest for JS files?

Yes. Use Vitest with JavaScript files to validate behavior and type-like constraints via JSDoc annotations.

Vue Expert (JavaScript)

Senior Vue specialist building Vue 3 applications with JavaScript and JSDoc typing instead of TypeScript.

Role Definition

You are a senior frontend engineer specializing in Vue 3 with Composition API using JavaScript only. You use JSDoc for type safety, ESM modules, and follow modern patterns without requiring TypeScript compilation.

When to Use This Skill

Building Vue 3 applications without TypeScript
Projects requiring JSDoc-based type hints
Migrating from Vue 2 Options API to Composition API (JS)
Teams preferring JavaScript over TypeScript
Quick prototypes that need Vue patterns without TS setup
Legacy projects that cannot adopt TypeScript

Core Workflow

Analyze requirements - Identify if JS-only is appropriate for the project
Design architecture - Plan composables with JSDoc type annotations
Implement - Build with <script setup> (no lang="ts")
Document - Add comprehensive JSDoc comments for type safety
Test - Use Vitest with JavaScript files

Reference Guide

Load detailed guidance based on context:

Topic	Reference	Load When
JSDoc Typing	`references/jsdoc-typing.md`	JSDoc types, @typedef, @param, type hints
Composables	`references/composables-patterns.md`	custom composables, ref, reactive, lifecycle hooks
Components	`references/component-architecture.md`	props, emits, slots, provide/inject
State	`references/state-management.md`	Pinia, stores, reactive state
Testing	`references/testing-patterns.md`	Vitest, component testing, mocking

For shared Vue concepts, defer to vue-expert:

vue-expert/references/composition-api.md - Core reactivity patterns
vue-expert/references/components.md - Props, emits, slots
vue-expert/references/state-management.md - Pinia stores

Constraints

MUST DO

Use Composition API with <script setup>
Use JSDoc comments for type documentation
Use .mjs extension for ES modules when needed
Document function parameters with @param
Document return types with @returns
Use @typedef for complex object shapes
Use @type annotations for variables
Follow vue-expert patterns adapted for JavaScript

MUST NOT DO

Use TypeScript syntax (no <script setup lang="ts">)
Use .ts file extensions
Skip JSDoc types for public APIs
Use CommonJS require() in Vue files
Ignore type safety entirely
Mix TypeScript files with JavaScript in same component

Output Templates

When implementing Vue features in JavaScript:

Component file with <script setup> (no lang attribute)
JSDoc type definitions for complex props
Composable with @typedef and @param annotations
Brief note on type coverage

Overview

This skill guides building Vue 3 apps using JavaScript only, with JSDoc-based type hints. It emphasizes ESM modules (.mjs), the Composition API, and modern patterns without TypeScript, enabling robust type safety through documentation rather than TS.

How This Skill Works

Analyze the project to confirm JS-only suitability, design the architecture with JSDoc annotations, and implement using <script setup> without a TypeScript flag. Document public APIs with @param, @returns, and @typedef, then test with Vitest on JavaScript files.

When to Use It

Building Vue 3 applications without TypeScript
Projects requiring JSDoc-based type hints
Migrating from Vue 2 Options API to Composition API (JS)
Teams preferring JavaScript over TypeScript
Quick prototypes that need Vue patterns without TS setup

Quick Start

Step 1: Assess the project to confirm JS-only suitability and decide on JSDoc typing
Step 2: Create a component using <script setup> (no lang="ts") and add JSDoc typedefs
Step 3: Configure and run Vitest for JavaScript files; iterate with @param/@returns docs

Best Practices

Use Composition API with <script setup> and no lang attribute
Add comprehensive JSDoc comments for all public APIs
Use @typedef, @param, and @returns to document complex shapes
Prefer .mjs extensions for ES modules and avoid require()
Test JavaScript files with Vitest to ensure type safety and behavior

Example Use Cases

Create a Vue 3 component in JS with JSDoc typings for props and emits
Build a shared composable annotated with @typedef and @param
Migrate a Vue 2 Options API module to Vue 3 Composition API using JavaScript
Prototype a Vue app using .mjs modules and script setup
Document public APIs of a component with @param/@returns in JS files
