feat: add Claude Code skill for Nuxt 4 best practices #33498
Conversation
Add comprehensive Nuxt 4 skill plugin with best practices and patterns: - New Nuxt 4 directory structure (app/ srcDir) - Singleton data fetching layer with shallow reactivity - Updated hydration patterns with NuxtTime component - Modern composables, server routes, and performance optimization - Reference files: composables, data-fetching, hydration, performance, plugins, server - Follows Claude Code skill best practices with gerund naming and detailed descriptions The skill provides guidance on useState, useFetch, useAsyncData, SSR optimization, and Nuxt 4-specific features for building modern web applications.

WalkthroughThis pull request adds a Nuxt-focused plugin marketplace configuration and a Nuxt plugin manifest, extensive Nuxt best-practices documentation (including a SKILL.md and reference files for composables, data fetching, hydration, performance, plugins, and server patterns), and new server-side utility exports for JWT authentication, session management, and a Prisma singleton. The marketplace file declares two plugins (local "nuxt" and remote "nuxt-ui"). All changes are additive; no existing files are modified.

321-321: ESLint parsing error in code example (line 321).Similar to the line 69 issue, this incomplete Vue template snippet is being parsed as code. The
<script setup>block is incomplete (missing closing tag in context), which triggers the parser error. See line 69 comment for recommended fix.
370-370: ESLint parsing error in code example (line 370).Similar to previous ESLint issues. This is part of an incomplete code example within documentation. See line 69 comment for the root cause and recommended fix.

1-510: Content quality: comprehensive Nuxt 4 best practices guide.The documentation provides thorough, well-structured coverage of Nuxt 4 fundamentals including the new
app/directory structure, composables, data fetching patterns (with Nuxt 4–specific changes like shallow reactivity and singleton patterns), server routes, SSR considerations, and advanced topics. Code examples follow established best practices and include both correct patterns (✅) and anti-patterns (❌) for comparison.The section on data fetching (lines 125–194) appropriately highlights Nuxt 4 improvements such as shallow reactivity defaults and reactive key support. The composables section correctly emphasises
useStatefor shared state and includes proper patterns withreadonly()wrappers to prevent accidental mutations.References to detailed guides (lines 498–504) provide clear pathways for developers needing deeper knowledge.
Consider adding explicit notes or callouts for potential gotchas with the shallow reactivity default (line 129) and when developers should use
deep: true(line 155) to aid quick comprehension. Additionally, cross-reference the hydration and performance guides earlier in the document, as these are critical for SSR success in Nuxt 4.

1-22: LGTM – complete plugin manifest.The plugin metadata is properly structured with all essential fields for marketplace integration.
plugins/nuxt/skills/nuxt-best-practices/reference/hydration.md (1)
1-386: Fix markdown linting issues: two violations require correction (MD022 claim is incorrect).The file has two genuine markdown linting violations, not three:
- Line 335 (MD040): Fenced code block missing language identifier. Change
```to```bash- Line 385 (MD047): File must end with a newline character
Add language to the code fence at line 335:
Nuxt shows warnings in development: -``` +```bash [Vue warn]: Hydration node mismatchAppend a newline character at the end of line 385 after "instead of localStorage for SSR-compatible storage".
Note: The file already has a blank line before the "## Table of Contents" heading (line 4), so there is no MD022 violation.
Likely an incorrect or invalid review comment.
plugins/nuxt/skills/nuxt-best-practices/reference/server.md (1)
1-567: Incorrect review comment. Rewrite with actual issues found.The review comment misidentifies the primary problems. Analysis confirms:
Issues NOT found (contrary to review):
- MD022 violations: No headings lack proper blank line spacing. Spot-checked lines 5, 17, 36, 52, 62, 88, 114, 148, 228, 236, 250 all have correct spacing.
Issues CORRECTLY identified but understated:
- MD040 (code fence language): 26 code blocks lack language identifiers (lines 18, 34, 48, 60, 84, 112, 146, 175, 193, 214, 226, 234, 248, 257, 276, 290, 308, 322, 359, 377, and others)—not limited to line 18.
- MD047 (trailing newline): File ends without newline character.
Root cause: Multiple bare
```blocks throughout the file, not a single directory structure block issue.Recommended fix:
Add language identifiers to all 26 code blocks (e.g.,```typescript,```bash,```shell) and add trailing newline to end of file. The markdown structure itself is sound; headings have appropriate spacing.Likely an incorrect or invalid review comment.

- No ESLint configuration found (.eslintrc not present anywhere)
- Code blocks properly formatted with

[analysis]
- Review claims "ESLint Parsing Errors (GitHub Check failures)" - FALSE: NO ESLint config in repository
- Review claims lines 20, 35, 103, 183, 201 have parsing errors - FALSE: these lines are within properly fenced code blocks
- Review claims MD022, MD040, MD047 violations - UNSUBSTANTIATED: files appear correctly formatted
- Review references "GitHub Check failures" without evidence
- All major claims are contradicted by actual codebase state
[conclusion]
This is an incorrect_review_comment. The reviewer either:
- Misread the file or copied from wrong context
- Referenced non-existent ESLint configuration
- Made false claims about GitHub check failures
- Misidentified markdown violations
The composables.md file contains no critical issues requiring the urgent fixes described.
The review comment contains incorrect and unsubstantiated claims and should be disregarded.
Key findings:
ESLint errors claimed but no configuration exists: The review references "ESLint Parsing Errors (GitHub Check failures)" at specific lines, but repository contains no ESLint configuration (no
.eslintrcfile, noeslintConfiginpackage.json). These claimed errors cannot exist without configuration.Code blocks are properly formatted: Inspected lines 19–40 confirm all TypeScript examples are within properly fenced code blocks with language identifiers (
```typescript), contradicting claims of parsing failures.Markdown violations unsubstantiated:
- Lines 1–10 show proper blank lines before headings (no MD022 violation)
- Lines 330–340 show code already within formatted blocks (no missing language identifiers)
- File structure appears correct
No evidence of GitHub Check failures: Workflow runs
pnpm lint, but no failing checks are documented; claims reference non-existent ESLint configuration.The file
plugins/nuxt/skills/nuxt-best-practices/reference/composables.md(471 lines) does not exhibit the critical issues described. Code examples are properly formatted and accessible to developers.Likely an incorrect or invalid review comment.

|
|
||
| ## Built-in Optimizations | ||
|
|
||
| ### Smart Prefetching with NuxtLink | ||
|
|
||
| ```vue | ||
| <template> | ||
| <!-- ✅ Auto-prefetch when visible (default) --> | ||
| <NuxtLink to="/about">About</NuxtLink> | ||
|
|
||
| <!-- ✅ Prefetch on hover/focus --> | ||
| <NuxtLink to="/contact" prefetch-on="interaction">Contact</NuxtLink> | ||
|
|
||
| <!-- ✅ Disable prefetch --> | ||
| <NuxtLink to="/heavy-page" :prefetch="false">Heavy Page</NuxtLink> | ||
| </template> | ||
| ``` | ||
|
|
||
| ### Data Fetching Optimization | ||
|
|
||
| ```typescript | ||
| // ✅ Prevents duplicate requests | ||
| const { data } = await useFetch('/api/users') | ||
| // Server: fetches data | ||
| // Client: reuses server data (no second request) | ||
|
|
||
| // ✅ Parallel data fetching | ||
| const [users, posts] = await Promise.all([ | ||
| useFetch('/api/users'), | ||
| useFetch('/api/posts') | ||
| ]) | ||
| ``` | ||
|
|
||
| ## Component Optimization | ||
|
|
||
| ### Lazy Loading Components | ||
|
|
||
| ```vue | ||
| <template> | ||
| <!-- ✅ Lazy load with Lazy prefix --> | ||
| <LazyHeavyChart v-if="showChart" /> | ||
| <LazyVideoPlayer :src="videoUrl" /> | ||
|
|
||
| <!-- ✅ Explicit lazy import --> | ||
| <component :is="HeavyComponent" v-if="loaded" /> | ||
| </template> | ||
|
|
||
| <script setup> | ||
| const HeavyComponent = defineAsyncComponent(() => | ||
| import('~/components/HeavyComponent.vue') | ||
| ) | ||
| </script> | ||
| ``` | ||
|
|
||
| ### Lazy Hydration | ||
|
|
||
| ```vue | ||
| <template> | ||
| <!-- ✅ Hydrate when visible --> | ||
| <LazyChart lazy-hydrate="visible" /> | ||
|
|
||
| <!-- ✅ Hydrate when idle --> | ||
| <LazyWidget lazy-hydrate="idle" /> | ||
|
|
||
| <!-- ✅ Hydrate on interaction --> | ||
| <LazyModal lazy-hydrate="interaction" /> | ||
| </template> | ||
| ``` | ||
|
|
||
| ### Client-Only Components | ||
|
|
||
| ```vue | ||
| <template> | ||
| <!-- ✅ Skip SSR, render on client only --> | ||
| <ClientOnly> | ||
| <MapComponent /> | ||
| <template #fallback> | ||
| <MapSkeleton /> | ||
| </template> | ||
| </ClientOnly> | ||
| </template> | ||
| ``` | ||
|
|
||
| ## Image Optimization | ||
|
|
||
| ### Using NuxtImg | ||
|
|
||
| ```vue | ||
| <template> | ||
| <!-- ✅ Auto-optimization --> | ||
| <NuxtImg | ||
| src="/hero.jpg" | ||
| width="800" | ||
| height="600" | ||
| format="webp" | ||
| quality="80" | ||
| loading="lazy" | ||
| /> | ||
|
|
||
| <!-- ✅ Critical images - eager load --> | ||
| <NuxtImg | ||
| src="/logo.png" | ||
| width="200" | ||
| height="100" | ||
| loading="eager" | ||
| preload | ||
| fetchpriority="high" | ||
| /> | ||
|
|
||
| <!-- ✅ Below-fold images - lazy load --> | ||
| <NuxtImg | ||
| src="/gallery-1.jpg" | ||
| width="400" | ||
| height="300" | ||
| loading="lazy" | ||
| fetchpriority="low" | ||
| /> | ||
| </template> | ||
| ``` | ||
|
|
||
| ### Using NuxtPicture | ||
|
|
||
| ```vue | ||
| <template> | ||
| <!-- ✅ Responsive images with art direction --> | ||
| <NuxtPicture | ||
| src="/hero.jpg" | ||
| :img-attrs="{ | ||
| class: 'hero-image', | ||
| alt: 'Hero banner' | ||
| }" | ||
| sizes="sm:100vw md:50vw lg:400px" | ||
| /> | ||
| </template> | ||
| ``` | ||
|
|
||
| ### Image Module Configuration | ||
|
|
||
| ```typescript | ||
| // nuxt.config.ts | ||
| export default defineNuxtConfig({ | ||
| modules: ['@nuxt/image'], | ||
| image: { | ||
| quality: 80, | ||
| format: ['webp', 'avif'], | ||
| screens: { | ||
| xs: 320, | ||
| sm: 640, | ||
| md: 768, | ||
| lg: 1024, | ||
| xl: 1280, | ||
| xxl: 1536 | ||
| } | ||
| } | ||
| }) | ||
| ``` | ||
|
|
||
| ## Font Optimization | ||
|
|
||
| ### Using Nuxt Fonts | ||
|
|
||
| ```typescript | ||
| // nuxt.config.ts | ||
| export default defineNuxtConfig({ | ||
| modules: ['@nuxt/fonts'], | ||
| fonts: { | ||
| families: [ | ||
| { name: 'Inter', provider: 'google' }, | ||
| { name: 'Roboto Mono', provider: 'google' } | ||
| ] | ||
| } | ||
| }) | ||
| ``` | ||
|
|
||
| Benefits: | ||
| - Auto self-hosting (no external requests) | ||
| - Fallback metrics to prevent layout shift | ||
| - Preload optimization | ||
|
|
||
| ### Manual Font Loading | ||
|
|
||
| ```vue | ||
| <!-- app.vue or layouts/default.vue --> | ||
| <script setup> | ||
| useHead({ | ||
| link: [ | ||
| { | ||
| rel: 'preload', | ||
| as: 'font', | ||
| type: 'font/woff2', | ||
| href: '/fonts/inter.woff2', | ||
| crossorigin: 'anonymous' | ||
| } | ||
| ] | ||
| }) | ||
| </script> | ||
| ``` | ||
|
|
||
| ## Code Splitting | ||
|
|
||
| ### Route-Based Splitting | ||
|
|
||
| ```typescript | ||
| // Automatic per-route splitting | ||
| pages/ | ||
| ├── index.vue # → _nuxt/index-[hash].js | ||
| ├── about.vue # → _nuxt/about-[hash].js | ||
| └── contact.vue # → _nuxt/contact-[hash].js | ||
| ``` | ||
|
|
||
| ### Component-Based Splitting | ||
|
|
||
| ```typescript | ||
| // ✅ Dynamic imports for large components | ||
| const HeavyComponent = defineAsyncComponent(() => | ||
| import('~/components/HeavyComponent.vue') | ||
| ) | ||
|
|
||
| // ✅ With loading state | ||
| const HeavyComponent = defineAsyncComponent({ | ||
| loader: () => import('~/components/HeavyComponent.vue'), | ||
| loadingComponent: LoadingSpinner, | ||
| delay: 200, | ||
| timeout: 3000 | ||
| }) | ||
| ``` | ||
|
|
||
| ### Vendor Splitting | ||
|
|
||
| ```typescript | ||
| // nuxt.config.ts | ||
| export default defineNuxtConfig({ | ||
| vite: { | ||
| build: { | ||
| rollupOptions: { | ||
| output: { | ||
| manualChunks: { | ||
| 'vendor-charts': ['chart.js', 'd3'], | ||
| 'vendor-utils': ['lodash-es', 'date-fns'] | ||
| } | ||
| } | ||
| } | ||
| } | ||
| } | ||
| }) | ||
| ``` | ||
|
|
||
| ## Caching Strategies | ||
|
|
||
| ### Route Rules | ||
|
|
||
| ```typescript | ||
| // nuxt.config.ts | ||
| export default defineNuxtConfig({ | ||
| routeRules: { | ||
| // Static generation at build time | ||
| '/': { prerender: true }, | ||
| '/about': { prerender: true }, | ||
|
|
||
| // Incremental Static Regeneration | ||
| '/blog/**': { isr: 3600 }, // Revalidate every hour | ||
|
|
||
| // Stale-While-Revalidate | ||
| '/api/posts': { swr: 3600 }, | ||
|
|
||
| // Client-side rendering only | ||
| '/dashboard/**': { ssr: false }, | ||
|
|
||
| // Custom cache headers | ||
| '/static/**': { | ||
| headers: { | ||
| 'cache-control': 'public, max-age=31536000, immutable' | ||
| } | ||
| } | ||
| } | ||
| }) | ||
| ``` | ||
|
|
||
| ### API Response Caching | ||
|
|
||
| ```typescript | ||
| // server/api/posts.get.ts | ||
| export default defineCachedEventHandler( | ||
| async (event) => { | ||
| const posts = await fetchPosts() | ||
| return posts | ||
| }, | ||
| { | ||
| maxAge: 60 * 60, // Cache for 1 hour | ||
| getKey: (event) => 'posts-list' | ||
| } | ||
| ) | ||
|
|
||
| // With query parameters | ||
| export default defineCachedEventHandler( | ||
| async (event) => { | ||
| const query = getQuery(event) | ||
| const posts = await fetchPosts(query) | ||
| return posts | ||
| }, | ||
| { | ||
| maxAge: 60 * 60, | ||
| getKey: (event) => { | ||
| const query = getQuery(event) | ||
| return `posts-${query.page}-${query.limit}` | ||
| } | ||
| } | ||
| ) | ||
| ``` | ||
|
|
||
| ### Client-Side Caching | ||
|
|
||
| ```typescript | ||
| // ✅ Cache with useFetch | ||
| const { data } = await useFetch('/api/posts', { | ||
| key: 'posts', | ||
| getCachedData(key) { | ||
| const cached = useNuxtData(key) | ||
| // Cache for 5 minutes | ||
| if (cached.data.value && Date.now() - cached.fetchedAt < 5 * 60 * 1000) { | ||
| return cached.data.value | ||
| } | ||
| } | ||
| }) | ||
| ``` | ||
|
|
||
| ## Third-Party Scripts | ||
|
|
||
| ### Using Nuxt Scripts | ||
|
|
||
| ```typescript | ||
| // nuxt.config.ts | ||
| export default defineNuxtConfig({ | ||
| modules: ['@nuxt/scripts'], | ||
| scripts: { | ||
| registry: { | ||
| googleAnalytics: { | ||
| id: 'G-XXXXXXXXXX' | ||
| } | ||
| } | ||
| } | ||
| }) | ||
|
|
||
| // Usage in component | ||
| <script setup> | ||
| useScript('googleAnalytics') | ||
| </script> | ||
| ``` | ||
|
|
||
| ### Manual Script Loading | ||
|
|
||
| ```typescript | ||
| // ✅ Defer non-critical scripts | ||
| useHead({ | ||
| script: [ | ||
| { | ||
| src: 'https://example.com/widget.js', | ||
| defer: true | ||
| } | ||
| ] | ||
| }) | ||
|
|
||
| // ✅ Load on interaction | ||
| const { load } = useScript('https://example.com/widget.js', { | ||
| trigger: 'manual' | ||
| }) | ||
|
|
||
| const loadWidget = async () => { | ||
| await load() | ||
| initializeWidget() | ||
| } | ||
| ``` | ||
|
|
||
| ## Bundle Size Optimization | ||
|
|
||
| ### Analyze Bundle | ||
|
|
||
| ```bash | ||
| # Build and analyze | ||
| npx nuxi analyze | ||
|
|
||
| # Opens visualization in browser | ||
| # Shows: | ||
| # - Bundle sizes per route | ||
| # - Shared chunks | ||
| # - Module composition | ||
| ``` | ||
|
|
||
| ### Tree Shaking | ||
|
|
||
| ```typescript | ||
| // ✅ Import only what you need | ||
| import { debounce } from 'lodash-es' | ||
|
|
||
| // ❌ Imports entire library | ||
| import _ from 'lodash' | ||
| ``` | ||
|
|
||
| ### Remove Unused Code | ||
|
|
||
| ```typescript | ||
| // nuxt.config.ts | ||
| export default defineNuxtConfig({ | ||
| // Remove console logs in production | ||
| vite: { | ||
| esbuild: { | ||
| drop: process.env.NODE_ENV === 'production' ? ['console', 'debugger'] : [] | ||
| } | ||
| } | ||
| }) | ||
| ``` | ||
|
|
||
| ## Profiling Tools | ||
|
|
||
| ### Nuxt DevTools | ||
|
|
||
| ```bash | ||
| # Enable DevTools | ||
| npx nuxi dev --devtools | ||
| ``` | ||
|
|
||
| Features: | ||
| - Component tree visualization | ||
| - Route rendering metrics | ||
| - Asset size analysis | ||
| - Network requests | ||
| - Payload inspection | ||
|
|
||
| ### Chrome DevTools | ||
|
|
||
| ```javascript | ||
| // Measure rendering performance | ||
| performance.mark('start') | ||
| // ... rendering code | ||
| performance.mark('end') | ||
| performance.measure('render-time', 'start', 'end') | ||
| ``` | ||
|
|
||
| ### Lighthouse | ||
|
|
||
| ```bash | ||
| # Run Lighthouse | ||
| npm install -g lighthouse | ||
| lighthouse http://localhost:3000 --view | ||
| ``` | ||
|
|
||
| Focus metrics: | ||
| - **LCP** (Largest Contentful Paint) - < 2.5s | ||
| - **FID** (First Input Delay) - < 100ms | ||
| - **CLS** (Cumulative Layout Shift) - < 0.1 | ||
| - **TTI** (Time to Interactive) - < 3.8s | ||
|
|
||
| ## Performance Checklist | ||
|
|
||
| ### Images | ||
| - [ ] Use NuxtImg/NuxtPicture for all images | ||
| - [ ] Set width/height to prevent layout shift | ||
| - [ ] Use `loading="lazy"` for below-fold images | ||
| - [ ] Use `loading="eager"` and `preload` for critical images | ||
| - [ ] Convert to WebP/Avif format | ||
|
|
||
| ### Fonts | ||
| - [ ] Use @nuxt/fonts module for auto-optimization | ||
| - [ ] Limit font variants (weights, styles) | ||
| - [ ] Preload critical fonts | ||
| - [ ] Use system fonts as fallbacks | ||
|
|
||
| ### Code Splitting | ||
| - [ ] Lazy load heavy components with `Lazy` prefix | ||
| - [ ] Use lazy hydration for non-critical components | ||
| - [ ] Dynamic import large libraries | ||
| - [ ] Split vendor bundles | ||
|
|
||
| ### Caching | ||
| - [ ] Set appropriate route rules (prerender, ISR, SWR) | ||
| - [ ] Cache API responses with `defineCachedEventHandler` | ||
| - [ ] Configure CDN cache headers | ||
| - [ ] Use client-side caching for repeated requests | ||
|
|
||
| ### Third-Party Scripts | ||
| - [ ] Defer non-critical scripts | ||
| - [ ] Use @nuxt/scripts module | ||
| - [ ] Load scripts on interaction when possible | ||
| - [ ] Audit script necessity | ||
|
|
||
| ### Monitoring | ||
| - [ ] Run Lighthouse regularly | ||
| - [ ] Monitor Core Web Vitals | ||
| - [ ] Use Nuxt DevTools for profiling | ||
| - [ ] Track bundle size in CI/CD | ||
|
|

|
||
| Guide to creating efficient and maintainable Nuxt plugins. | ||

| - [Performance Considerations](#performance-considerations) | ||
| - [Client vs Server Plugins](#client-vs-server-plugins) | ||
| - [Async Plugins](#async-plugins) | ||

|
|
||
| ## Plugin Basics | ||
|
|
||
| ### Creating a Plugin | ||
|
|
||
| ```typescript | ||
| // plugins/my-plugin.ts | ||
| export default defineNuxtPlugin(() => { | ||
| // Plugin initialization logic | ||
|
|
||
| return { | ||
| provide: { | ||
| myFunction: () => 'Hello from plugin' | ||
| } | ||
| } | ||
| }) | ||
|
|
||
| // Usage in component | ||
| const { $myFunction } = useNuxtApp() | ||
| console.log($myFunction()) // "Hello from plugin" | ||
| ``` | ||
|
|
||
| ### Plugin Execution Order | ||
|
|
||
| By default, plugins load synchronously in alphabetical order: | ||
|
|
||
| ``` | ||
| plugins/ | ||
| ├── 01.first.ts # Loads first | ||
| ├── 02.second.ts # Loads second | ||
| └── 03.third.ts # Loads third | ||
| ``` | ||
|
|
||
| ## Performance Considerations | ||
|
|
||
| ### Minimize Plugin Overhead | ||
|
|
||
| ```typescript | ||
| // ❌ Bad - Heavy computation in plugin | ||
| export default defineNuxtPlugin(() => { | ||
| // Blocks hydration! | ||
| const heavyData = processLargeDataset() | ||
|
|
||
| return { | ||
| provide: { heavyData } | ||
| } | ||
| }) | ||
|
|
||
| // ✅ Good - Lazy initialization | ||
| export default defineNuxtPlugin(() => { | ||
| let cachedData: Data | null = null | ||
|
|
||
| const getData = async () => { | ||
| if (!cachedData) { | ||
| cachedData = await processLargeDataset() | ||
| } | ||
| return cachedData | ||
| } | ||
|
|
||
| return { | ||
| provide: { getData } | ||
| } | ||
| }) | ||
| ``` | ||
|
|
||
| ### Prefer Composables Over Plugins | ||
|
|
||
| ```typescript | ||
| // ❌ Unnecessary plugin | ||
| // plugins/utils.ts | ||
| export default defineNuxtPlugin(() => { | ||
| const formatDate = (date: Date) => { | ||
| return date.toLocaleDateString() | ||
| } | ||
|
|
||
| return { | ||
| provide: { formatDate } | ||
| } | ||
| }) | ||
|
|
||
| // ✅ Better - Use composable | ||
| // composables/useFormatters.ts | ||
| export const useFormatters = () => { | ||
| const formatDate = (date: Date) => { | ||
| return date.toLocaleDateString() | ||
| } | ||
|
|
||
| return { formatDate } | ||
| } | ||
| ``` | ||
|
|
||
| **When to use plugins:** | ||
| - Global Vue directives | ||
| - Global mixins | ||
| - Third-party library integration | ||
| - App-level initialization | ||
|
|
||
| **When to use composables:** | ||
| - Utility functions | ||
| - State management | ||
| - Reusable logic | ||
| - Data fetching helpers | ||
|
|
||
| ## Client vs Server Plugins | ||
|
|
||
| ### Client-Only Plugin | ||
|
|
||
| ```typescript | ||
| // plugins/analytics.client.ts | ||
| export default defineNuxtPlugin(() => { | ||
| // Only runs on client | ||
| window.gtag('config', 'GA_MEASUREMENT_ID') | ||
|
|
||
| return { | ||
| provide: { | ||
| trackEvent: (event: string) => { | ||
| window.gtag('event', event) | ||
| } | ||
| } | ||
| } | ||
| }) | ||
| ``` | ||
|
|
||
| ### Server-Only Plugin | ||
|
|
||
| ```typescript | ||
| // plugins/database.server.ts | ||
| export default defineNuxtPlugin(() => { | ||
| // Only runs on server | ||
| const db = new DatabaseClient() | ||
|
|
||
| return { | ||
| provide: { | ||
| db | ||
| } | ||
| } | ||
| }) | ||
| ``` | ||
|
|
||
| ### Universal Plugin with Guards | ||
|
|
||
| ```typescript | ||
| // plugins/logger.ts | ||
| export default defineNuxtPlugin(() => { | ||
| const log = (message: string) => { | ||
| if (process.client) { | ||
| console.log('[Client]', message) | ||
| } else { | ||
| console.log('[Server]', message) | ||
| } | ||
| } | ||
|
|
||
| return { | ||
| provide: { log } | ||
| } | ||
| }) | ||
| ``` | ||
|
|
||
| ## Async Plugins | ||
|
|
||
| ### Parallel Loading | ||
|
|
||
| ```typescript | ||
| // plugins/firebase.client.ts | ||
| export default defineNuxtPlugin({ | ||
| name: 'firebase', | ||
| parallel: true, // Don't block other plugins | ||
| async setup() { | ||
| const { initializeApp } = await import('firebase/app') | ||
| const { getAuth } = await import('firebase/auth') | ||
|
|
||
| const app = initializeApp({ | ||
| apiKey: 'xxx', | ||
| authDomain: 'xxx' | ||
| }) | ||
|
|
||
| const auth = getAuth(app) | ||
|
|
||
| return { | ||
| provide: { | ||
| firebase: { app, auth } | ||
| } | ||
| } | ||
| } | ||
| }) | ||
| ``` | ||
|
|
||
| ### Sequential Loading | ||
|
|
||
| ```typescript | ||
| // plugins/01.config.ts | ||
| export default defineNuxtPlugin(async () => { | ||
| // Must load before other plugins | ||
| const config = await $fetch('/api/config') | ||
|
|
||
| return { | ||
| provide: { config } | ||
| } | ||
| }) | ||
|
|
||
| // plugins/02.feature.ts | ||
| export default defineNuxtPlugin(() => { | ||
| const { $config } = useNuxtApp() | ||
|
|
||
| // Uses config from previous plugin | ||
| initFeature($config) | ||
| }) | ||
| ``` | ||
|
|
||
| ### Dependency Handling | ||
|
|
||
| ```typescript | ||
| // plugins/api.client.ts | ||
| export default defineNuxtPlugin({ | ||
| name: 'api', | ||
| dependsOn: ['auth'], // Wait for auth plugin | ||
| setup() { | ||
| const { $auth } = useNuxtApp() | ||
|
|
||
| const api = { | ||
| fetch: async (url: string) => { | ||
| return await $fetch(url, { | ||
| headers: { | ||
| Authorization: `Bearer ${$auth.token}` | ||
| } | ||
| }) | ||
| } | ||
| } | ||
|
|
||
| return { | ||
| provide: { api } | ||
| } | ||
| } | ||
| }) | ||
| ``` | ||
|
|
||
| ## Plugin Patterns | ||
|
|
||
| ### Vue Plugin Integration | ||
|
|
||
| ```typescript | ||
| // plugins/vue-plugin.ts | ||
| import VuePlugin from 'vue-plugin' | ||
|
|
||
| export default defineNuxtPlugin((nuxtApp) => { | ||
| nuxtApp.vueApp.use(VuePlugin, { | ||
| // Plugin options | ||
| }) | ||
| }) | ||
| ``` | ||
|
|
||
| ### Global Directive | ||
|
|
||
| ```typescript | ||
| // plugins/directives.ts | ||
| export default defineNuxtPlugin((nuxtApp) => { | ||
| nuxtApp.vueApp.directive('focus', { | ||
| mounted(el) { | ||
| el.focus() | ||
| } | ||
| }) | ||
| }) | ||
|
|
||
| // Usage | ||
| <template> | ||
| <input v-focus /> | ||
| </template> | ||
| ``` | ||
|
|
||
| ### Error Handler | ||
|
|
||
| ```typescript | ||
| // plugins/error-handler.ts | ||
| export default defineNuxtPlugin((nuxtApp) => { | ||
| nuxtApp.vueApp.config.errorHandler = (error, instance, info) => { | ||
| console.error('Global error:', error) | ||
| console.error('Component:', instance) | ||
| console.error('Error info:', info) | ||
| } | ||
| }) | ||
| ``` | ||
|
|
||
| ### Router Integration | ||
|
|
||
| ```typescript | ||
| // plugins/router-guards.ts | ||
| export default defineNuxtPlugin(() => { | ||
| const router = useRouter() | ||
|
|
||
| router.beforeEach((to, from) => { | ||
| console.log('Navigating to:', to.path) | ||
|
|
||
| // Add analytics, auth checks, etc. | ||
| }) | ||
|
|
||
| router.afterEach((to, from) => { | ||
| console.log('Navigated from:', from.path, 'to:', to.path) | ||
| }) | ||
| }) | ||
| ``` | ||
|
|
||
| ### API Client Pattern | ||
|
|
||
| ```typescript | ||
| // plugins/api.ts | ||
| export default defineNuxtPlugin(() => { | ||
| const config = useRuntimeConfig() | ||
|
|
||
| const api = $fetch.create({ | ||
| baseURL: config.public.apiBase, | ||
| onRequest({ options }) { | ||
| // Add auth headers | ||
| const token = useCookie('auth-token') | ||
| if (token.value) { | ||
| options.headers = { | ||
| ...options.headers, | ||
| Authorization: `Bearer ${token.value}` | ||
| } | ||
| } | ||
| }, | ||
| onResponseError({ response }) { | ||
| // Handle errors globally | ||
| if (response.status === 401) { | ||
| navigateTo('/login') | ||
| } | ||
| } | ||
| }) | ||
|
|
||
| return { | ||
| provide: { api } | ||
| } | ||
| }) | ||
| ``` | ||
|
|
||
| ## Type Safety | ||
|
|
||
| ### TypeScript Plugin Definition | ||
|
|
||
| ```typescript | ||
| // plugins/typed-plugin.ts | ||
| interface MyPlugin { | ||
| greet: (name: string) => string | ||
| farewell: (name: string) => string | ||
| } | ||
|
|
||
| export default defineNuxtPlugin(() => { | ||
| const plugin: MyPlugin = { | ||
| greet: (name) => `Hello, ${name}!`, | ||
| farewell: (name) => `Goodbye, ${name}!` | ||
| } | ||
|
|
||
| return { | ||
| provide: { | ||
| myPlugin: plugin | ||
| } | ||
| } | ||
| }) | ||
| ``` | ||
|
|
||
| ### Type Augmentation | ||
|
|
||
| ```typescript | ||
| // types/plugins.d.ts | ||
| declare module '#app' { | ||
| interface NuxtApp { | ||
| $myPlugin: { | ||
| greet: (name: string) => string | ||
| farewell: (name: string) => string | ||
| } | ||
| } | ||
| } | ||
|
|
||
| // Usage with full type safety | ||
| const { $myPlugin } = useNuxtApp() | ||
| $myPlugin.greet('World') // Type-safe! | ||
| ``` | ||
|
|
||
| ### Generic Plugin | ||
|
|
||
| ```typescript | ||
| // plugins/storage.ts | ||
| export default defineNuxtPlugin(() => { | ||
| const storage = { | ||
| get: <T>(key: string): T | null => { | ||
| const value = localStorage.getItem(key) | ||
| return value ? JSON.parse(value) : null | ||
| }, | ||
| set: <T>(key: string, value: T): void => { | ||
| localStorage.setItem(key, JSON.stringify(value)) | ||
| } | ||
| } | ||
|
|
||
| return { | ||
| provide: { storage } | ||
| } | ||
| }) | ||
|
|
||
| // Usage | ||
| const user = $storage.get<User>('user') // Type: User | null | ||
| ``` | ||
|
|
||
| ## Hooks Integration | ||
|
|
||
| ### Using Nuxt Hooks | ||
|
|
||
| ```typescript | ||
| // plugins/lifecycle.ts | ||
| export default defineNuxtPlugin((nuxtApp) => { | ||
| nuxtApp.hook('app:created', () => { | ||
| console.log('App created') | ||
| }) | ||
|
|
||
| nuxtApp.hook('app:mounted', () => { | ||
| console.log('App mounted') | ||
| }) | ||
|
|
||
| nuxtApp.hook('page:start', () => { | ||
| console.log('Page navigation started') | ||
| }) | ||
|
|
||
| nuxtApp.hook('page:finish', () => { | ||
| console.log('Page navigation finished') | ||
| }) | ||
| }) | ||
| ``` | ||
|
|
||
| ## Best Practices Summary | ||
|
|
||
| 1. **Minimize plugin overhead** - plugins run during hydration | ||
| 2. **Use composables when possible** - lighter than plugins | ||
| 3. **Enable `parallel: true`** for async plugins | ||
| 4. **Use `.client` suffix** for browser-only code | ||
| 5. **Use `.server` suffix** for server-only code | ||
| 6. **Lazy initialize** expensive operations | ||
| 7. **Provide type definitions** for better DX | ||
| 8. **Use plugin dependencies** for ordered loading | ||
| 9. **Handle errors gracefully** in plugins | ||
| 10. **Document plugin purpose** and usage | ||
|
|
||
| ## Common Patterns | ||
|
|
||

ESLint parsing error in code example.
ESLint is attempting to parse the incomplete code example at this line as TypeScript. Since this is a markdown documentation file with intentionally incomplete examples (using { ... } as a placeholder), the ESLint configuration should exclude this file or markdown files should not be linted for code syntax. Alternatively, ensure all code examples in markdown are complete snippets or clearly marked as pseudo-code.

ESLint markdown processing confirmed; code blocks are parsed and incomplete syntax will cause parser errors.
The repository's ESLint configuration (eslint.config.mjs) uses @eslint/markdown and explicitly processes all markdown files (**/*.md pattern) with code blocks extracted and parsed as virtual files (**/*.md/**/*). Whilst certain linting rules are disabled for markdown code blocks, parser-level errors occur before those rules are applied.
The incomplete example on line 69—export const useAuth = () => { ... }—contains invalid TypeScript syntax that the parser cannot resolve, causing ESLint processing to fail. The configuration should either:
- Exclude markdown files from linting entirely, or
- Exclude the
plugins/nuxt/skills/nuxt-best-practices/SKILL.mdfile specifically, or - Replace incomplete placeholders with valid, compilable code snippets (even if stubbed).

In plugins/nuxt/skills/nuxt-best-practices/SKILL.md around line 69, the inline
snippet "export const useAuth = () => { ... }" is invalid TypeScript and breaks
ESLint's markdown code extraction; fix by either replacing the placeholder with
a minimal valid stub (for example a compilable arrow function or named export
that returns a typed value) so the code block parses, or update
eslint.config.mjs to exclude markdown files (or this specific file) from
extraction by removing or narrowing the "**/*.md" pattern (or adding the file to
an exclude list) — pick one approach and apply the change consistently, then run
the linter to confirm the parser error is resolved.

Fix improperly fenced "Usage in page" code block.

486-501: Verify JWT implementation completeness.The JWT pattern shown is correct, but the
verifyPasswordfunction used on line 511 is referenced without being defined or imported in the shown code. Whilst this is acceptable in a reference document (as it's a conceptual example), consider adding a note that this function should be implemented or imported from a utility library.Consider adding a clarifying comment:
// server/api/auth/login.post.ts export default defineEventHandler(async (event) => { const { email, password } = await readBody(event) const user = await prisma.user.findUnique({ where: { email } }) - if (!user || !(await verifyPassword(password, user.password))) { + // Note: verifyPassword should be implemented using bcrypt or similar + if (!user || !(await verifyPassword(password, user.password))) { throw createError({ statusCode: 401, message: 'Invalid credentials' }) }
