clerk-vue-patterns
Vue 3 patterns with Clerk — composables (useAuth, useUser, useClerk, useOrganization), Vue Router guards, Pinia auth store integration. Triggers on: vue clerk, useAuth vue, clerk composables, vue router clerk guard, pinia auth clerk. For Nuxt, use clerk-nuxt-patterns instead.
What this skill does
# Vue Patterns
SDK: `@clerk/vue` v2+ (Vue 3). For Nuxt, use `clerk-nuxt-patterns`.
## What Do You Need?
| Task | Reference |
|------|-----------|
| Composables: useAuth, useUser, useOrganization | references/composables.md |
| Vue Router navigation guards | references/vue-router-guards.md |
| Pinia store with auth state | references/pinia-integration.md |
## Mental Model
Vue uses composables from `@clerk/vue`:
- **`useAuth()`** — reactive `isSignedIn`, `userId`, `signOut`
- **`useUser()`** — reactive `user` object
- **`useClerk()`** — full Clerk instance for advanced operations
- **`useOrganization()`** — reactive `organization`, `membership`
## Setup
### Vue (Plain)
```ts
// main.ts
import { clerkPlugin } from '@clerk/vue'
import { createApp } from 'vue'
import App from './App.vue'
const app = createApp(App)
app.use(clerkPlugin, {
publishableKey: import.meta.env.VITE_CLERK_PUBLISHABLE_KEY,
})
app.mount('#app')
```
## Composables Usage
```vue
<script setup lang="ts">
import { useAuth, useUser } from '@clerk/vue'
const { isSignedIn, userId, signOut } = useAuth()
const { user } = useUser()
</script>
<template>
<div v-if="isSignedIn">
<p>Hello {{ user?.firstName }}</p>
<button @click="signOut()">Sign Out</button>
</div>
<SignInButton v-else />
</template>
```
## Org Switching
```vue
<script setup lang="ts">
import { useOrganizationList } from '@clerk/vue'
const { userMemberships, setActive } = useOrganizationList()
</script>
<template>
<button
v-for="mem in userMemberships.data ?? []"
:key="mem.organization.id"
@click="setActive({ organization: mem.organization.id })"
>
{{ mem.organization.name }}
</button>
</template>
```
## Common Pitfalls
| Symptom | Cause | Fix |
|---------|-------|-----|
| Composables return `undefined` | Not inside `ClerkProvider` tree | Ensure `app.use(clerkPlugin, { publishableKey })` is called |
| `userId` reactive but not updating | Destructuring loses reactivity | Use `const { userId } = useAuth()` (toRefs-style composable, reactive) |
## Import Map
| What | Import |
|------|--------|
| Composables | `@clerk/vue` |
| Plugin setup | `@clerk/vue` |
| Components | `@clerk/vue` |

IncludedLightning Web Components with PICKLES methodology and 165-point scoring. Use this skill when the user creates or edits LWC components, builds wire service patterns, or writes Jest tests for LWC. TRIGGER when: user creates/edits LWC components, touches lwc/**/*.js, .html, .css, .js-meta.xml files, or asks about wire service, SLDS, or Jest LWC tests. DO NOT TRIGGER when: Apex classes (use generating-apex), Aura components, or Visualforce.
tanstack-query
IncludedManage server state in React with TanStack Query v5. Set up queries with useQuery, mutations with useMutation, configure QueryClient caching strategies, implement optimistic updates, and handle infinite scroll with useInfiniteQuery. Use when: setting up data fetching in React projects, migrating from v4 to v5, or fixing object syntax required errors, query callbacks removed issues, cacheTime renamed to gcTime, isPending vs isLoading confusion, keepPreviousData removed problems.

IncludedProcess documents with Nutrient DWS. Use when the user wants to generate PDFs from HTML or URLs, convert Office/images/PDFs, assemble or split packets, OCR scans, extract text/tables/key-value pairs, redact PII, watermark, sign, fill forms, optimize PDFs, or produce compliance outputs like PDF/A or PDF/UA. Triggers include convert to PDF, merge these PDFs, OCR this scan, extract tables, redact PII, sign this PDF, make this PDF/A, or linearize for web delivery.
