Nuxt Module Development

Guide for creating Nuxt modules that extend framework functionality.

Related skills: nuxt (basics), vue (runtime patterns)

Quick Start

npx nuxi init -t module my-module
cd my-module && npm install
npm run dev        # Start playground
npm run dev:build  # Build in watch mode
npm run test       # Run tests

Available Guidance

• references/development.md - Module anatomy, defineNuxtModule, Kit utilities, hooks
• references/testing-and-publishing.md - E2E testing, best practices, releasing, publishing
• references/ci-workflows.md - Copy-paste CI/CD workflow templates

Loading Files

Consider loading these reference files based on your task:

• references/development.md - if building module features, using defineNuxtModule, or working with Kit utilities
• references/testing-and-publishing.md - if writing E2E tests, publishing to npm, or following best practices
• references/ci-workflows.md - if setting up CI/CD workflows for your module

DO NOT load all files at once. Load only what's relevant to your current task.

Module Types

Type	Location	Use Case
Published	npm package	@nuxtjs/, nuxt- distribution
Local	modules/ dir	Project-specific extensions
Inline	nuxt.config.ts	Simple one-off hooks
