📦 Installation

Requires Vue ^3.3.0 and Vue Router ^4.2.0 or ^5.0.0.

npm install vue3-router-tab
# or
pnpm add vue3-router-tab
# or
yarn add vue3-router-tab

🚀 Quick Start

1. Register the Plugin

// main.ts
import { createApp } from 'vue'
import App from './App.vue'
import router from './router'
import RouterTab from 'vue3-router-tab'

const app = createApp(App)
app.use(router)
app.use(RouterTab)
app.mount('#app')

2. Basic Usage

<template>
  <router-tab />
</template>

That's it! You now have a fully functional tabbed router interface.

3. Enhanced Usage with Persistence

<template>
  <router-tab
    cookie-key="my-app-tabs"
    :sortable="true"
    :keep-alive="true"
  />
</template>

📖 Usage Guide

Basic Configuration

<template>
  <router-tab
    cookie-key="app-tabs"
    :keep-alive="true"
    :max-alive="10"
    :keep-last-tab="true"
    :sortable="true"
    page-transition="router-tab-fade"
    tab-transition="router-tab-zoom"
  />
</template>

Route Configuration

Configure your routes with tab metadata:

// router/index.ts
const routes = [
  {
    path: '/',
    component: Home,
    meta: {
      title: 'Home',
      icon: 'mdi-home',
      keepAlive: true,
    },
  },
  {
    path: '/users',
    component: Users,
    meta: {
      title: 'Users',
      icon: 'mdi-account-group',
      closable: true,
      keepAlive: true,
    },
  },
  {
    path: '/settings',
    component: Settings,
    meta: {
      title: 'Settings',
      icon: 'mdi-cog',
      closable: false, // Can't be closed
      keepAlive: false,
    },
  },
]

Reactive Tab Properties

Make your tabs dynamic by exposing reactive properties in your components:

<template>
  <div>
    <h1>{{ pageTitle }}</h1>
    <button @click="updateTitle">Update Title</button>
    <div v-if="loading">Loading...</div>
  </div>
</template>

<script setup lang="ts">
import { ref, computed } from 'vue'

// These reactive properties automatically update the tab
const pageTitle = ref('Dashboard')
const loading = ref(false)
const notificationCount = ref(0)

// Tab title updates automatically
const routeTabTitle = computed(() => {
  if (loading.value) return 'Loading...'
  if (notificationCount.value > 0) return `Dashboard (${notificationCount.value})`
  return pageTitle.value
})

// Tab icon changes based on state
const routeTabIcon = computed(() =>
  loading.value ? 'mdi-loading mdi-spin' : 'mdi-view-dashboard'
)

// Prevent closing while loading
const routeTabClosable = computed(() => !loading.value)

function updateTitle() {
  pageTitle.value = 'Updated Dashboard'
}
</script>

🎨 Transitions

Choose from 7 built-in transition effects:

<!-- Default transition -->
<router-tab />

<!-- Custom transition -->
<router-tab page-transition="router-tab-scale" />

<!-- Advanced configuration -->

})
</script>

🔍 Troubleshooting

Common Issues

Tabs not updating titles

• Ensure you're using ref() or computed() for reactive properties
• Check that properties are properly exposed in <script setup>

Transitions not working

• Don't use custom #default slot without transitions
• Ensure transition names match available transitions

Persistence not working

• Check that cookies are enabled
• Verify cookie-key prop is set
• Check browser console for cookie errors

KeepAlive not preserving state

• Ensure routes have keepAlive: true in meta
• Check that components have unique keys

TypeScript errors

import type { TabRecord, RouterTabsOptions } from 'vue3-router-tab'

Performance Tips

• Use maxAlive to limit cached components
• Avoid deep watchers in tab components
• Use evictCache() to manually clear cache when needed
• Consider using keepAlive: false for memory-intensive components

🌟 Migration Guide

From v1.x to v2.x

// Before
import RouterTab from 'vue3-router-tab'

// After (same)
import RouterTab from 'vue3-router-tab'

The API is backward compatible. New features are additive.

Context Menu Prop Update

The legacy contextmenu prop alias has been removed.

Use:

<router-tab :contextMenu="true" />

Instead of:

<router-tab :contextmenu="true" />

Configuration

RouterTab Props

Page Transitions

Vue3 Router Tab includes 7 built-in page transition effects that are displayed when switching between tabs or refreshing pages.

Available Transitions

Using Transitions

Default Transition

<router-tab />
<!-- Uses router-tab-swap by default -->

Custom Transition

<router-tab 
  :page-transition="{ name: 'router-tab-scale', mode: 'out-in' }"
/>

String Shorthand

<router-tab page-transition="router-tab-fade" />

Dynamic Transitions

Change transitions at runtime:

<template>
  <div>
    <select v-model="currentTransition">
      <option value="router-tab-swap">Swap</option>
      <option value="router-tab-slide">Slide</option>
      <option value="router-tab-fade">Fade</option>
      <option value="router-tab-scale">Scale</option>
      <option value="router-tab-flip">Flip</option>
      <option value="router-tab-rotate">Rotate</option>
      <option value="router-tab-bounce">Bounce</option>
    </select>
    
    <router-tab 
      :page-transition="{ name: currentTransition, mode: 'out-in' }"
    />
  </div>
</template>

<script setup>
import { ref } from 'vue'
const currentTransition = ref('router-tab-swap')
</script>

Custom Transitions

Create your own transitions by defining CSS classes:

/* Your custom transition */
.my-custom-enter-active,
.my-custom-leave-active {
  transition: all 0.5s ease;
}

.my-custom-enter-from {
  opacity: 0;
  transform: translateX(100px);
}

.my-custom-leave-to {
  opacity: 0;
  transform: translateX(-100px);
}

<router-tab page-transition="my-custom" />

Transition Tips

• Performance: Use mode: 'out-in' for smooth transitions without layout shifts
• Duration: Built-in transitions are optimized at 0.5-0.8 seconds
• Accessibility: Consider users with motion sensitivity - provide options to disable
• Context: Match transition style to your app's design language

Changing Tab Titles Dynamically

Vue3 Router Tab automatically watches for reactive properties in your page components and updates the corresponding tab information in real-time.

Quick Start

Simply expose reactive properties from your component:

<template>
  <div>
    <h1>{{ routeTabTitle }}</h1>
    <button @click="updateTitle">Change Tab Title</button>
  </div>
</template>

<script setup>
import { ref } from 'vue'

// This ref is automatically watched - tab title updates when it changes!
const routeTabTitle = ref('My Page')

function updateTitle() {
  routeTabTitle.value = 'Updated Title'
}
</script>

Watched Properties

The following reactive properties are automatically monitored:

Dynamic Titles with Computed

Create titles that update based on your component state:

<script setup>
import { ref, computed } from 'vue'

const isLoading = ref(false)
const notifications = ref(0)

// Tab title automatically updates when dependencies change
const routeTabTitle = computed(() => {
  if (isLoading.value) return 'Loading...'
  if (notifications.value > 0) return `Messages (${notifications.value})`
  return 'Dashboard'
})

// Tab icon changes based on state
const routeTabIcon = computed(() => 
  isLoading.value ? 'mdi-loading mdi-spin' : 'mdi-view-dashboard'
)

// Prevent closing during operations
const routeTabClosable = computed(() => !isLoading.value)
</script>

Real-World Examples

Example 1: User Profile with Name

<script setup>
import { ref, computed, onMounted } from 'vue'

const user = ref(null)
const isLoading = ref(true)

const routeTabTitle = computed(() => 
  isLoading.value ? 'Loading...' : `Profile - ${user.value?.name || 'Unknown'}`
)

const routeTabIcon = computed(() => 
  isLoading.value ? 'mdi-loading mdi-spin' : 'mdi-account'
)

onMounted(async () => {
  user.value = await fetchUser()
  isLoading.value = false
})
</script>

Example 2: Form with Unsaved Changes

<script setup>
import { ref, computed } from 'vue'

const formData = ref({})
const hasUnsavedChanges = ref(false)

const routeTabTitle = computed(() => 
  hasUnsavedChanges.value ? '• Edit Form' : 'Edit Form'
)

const routeTabClosable = computed(() => !hasUnsavedChanges.value)

function onChange() {
  hasUnsavedChanges.value = true
}
</script>

Example 3: Real-time Notifications

<script setup>
import { ref, computed, onMounted } from 'vue'

const unreadCount = ref(0)

const routeTabTitle = computed(() => {
  if (unreadCount.value === 0) return 'Messages'
  return `Messages (${unreadCount.value})`
})

const routeTabIcon = computed(() => 
  unreadCount.value > 0 ? 'mdi-bell-badge' : 'mdi-bell-outline'
)

// Simulate real-time updates
onMounted(() => {
  setInterval(() => {
    unreadCount.value = Math.floor(Math.random() * 10)
  }, 5000)
})
</script>

Using the Composable API

For advanced use cases, use the useReactiveTab composable:

<script setup>
import { useReactiveTab } from 'vue3-router-tab'
import { ref } from 'vue'

const user = ref({ name: 'John Doe', status: 'online' })

const { 
  routeTabTitle, 
  routeTabIcon, 
  routeTabClosable 
} = useReactiveTab({
  title: () => `${user.value.name} - ${user.value.status}`,
  icon: () => user.value.status === 'online' ? 'mdi-account' : 'mdi-account-off',
 closable: () => user.value.status !== 'editing'
})
</script>

Important Notes

1. Automatic Exposure in <script setup>: Properties defined in <script setup> are automatically exposed - no need for defineExpose()
2. Reactive types: Use ref() or computed() - plain values won't trigger updates
3. Automatic watching: No manual watchers needed - the plugin handles everything
4. Performance: Only active tab components are watched to minimize overhead

Works inside KeepAlive and wrappers

<router-tab> forwards the tab bindings even when your pages are wrapped for caching. Just expose reactive values (refs/computed) and they will still be watched:

<script setup>
import { computed, ref } from 'vue'

const count = ref(3)
const isLoading = ref(false)

const routeTabTitle = computed(() => isLoading.value ? 'Loading orders…' : `Orders (${count.value})`)
const routeTabIcon = computed(() => isLoading.value ? 'mdi-loading mdi-spin' : 'mdi-cart')
const routeTabClosable = computed(() => !isLoading.value)
</script>

💡 Try it yourself: Check out the live demo at /title-test in the example app to see all these features in action!

Options API Support

If you're using the Options API, you need to expose the properties:

<script>
import { ref, computed } from 'vue'

export default {
  setup() {
    const routeTabTitle = ref('My Page')
    const routeTabIcon = computed(() => 'mdi-page')
    
    return {
      routeTabTitle,
      routeTabIcon
    }
  }
}
</script>

Or with defineExpose:

<script setup>
import { ref } from 'vue'

const routeTabTitle = ref('My Page')

// Only needed if you're NOT using top-level refs in <script setup>
defineExpose({ routeTabTitle })
</script>

Note: With <script setup>, top-level bindings are automatically exposed, so defineExpose is typically not needed.

Tab Closing Behavior

When a tab is closed, the plugin automatically navigates to the next available tab with the following priority:

1. Next tab - The tab immediately to the right
2. Previous tab - The tab immediately to the left
3. First tab - If no adjacent tabs exist
4. Default route - If no other tabs exist

Cookie persistence

<router-tab cookie-key="…" /> is usually all you need. If you prefer fine grained control (custom expiry, same-site, etc.) you can still use the headless helper:

<router-tab>
  <template #start>
    <router-tabs
      cookie-key="app-tabs"
      :expires-in-days="14"
      fallback-route="/dashboard"
    />
  </template>
</router-tab>

Want to wire it up yourself?

<script setup lang="ts">
import { useRouterTabsPersistence } from 'vue3-router-tab'

useRouterTabsPersistence({
  cookieKey: 'app-tabs',
  expiresInDays: 30,
  fallbackRoute: '/dashboard'
})
</script>

The composable also exposes serialize / deserialize options so you can encrypt or customise the cookie payload. Use storage: 'localStorage' or provide a custom storage adapter when cookies are not a good fit. debounceMs can reduce repeated writes during rapid tab changes.

Theme system

The plugin initialises a lightweight theme layer on install:

• Reads tab-theme-style ('light', 'dark', or 'system'; defaults to 'system').
• Reads tab-theme-primary-color (defaults to #0f172a).
• Applies the choice via data-theme and --theme-primary CSS variables, keeping “system” in sync with OS changes.

Override the theme at runtime:

import { setRouterTabsTheme, setRouterTabsPrimary } from 'vue3-router-tab'

setRouterTabsTheme('dark')
setRouterTabsPrimary('#22c55e')

Customise the defaults with:

import { initRouterTabsTheme } from 'vue3-router-tab'

initRouterTabsTheme({
  defaultStyle: 'dark',
  defaultPrimary: '#0ea5e9'
})

Custom rendering

You can override the default routed view by providing a #default slot. The slot receives the same values you would normally get from <RouterView v-slot>:

<router-tab cookie-key="app-tabs">
  <template #default="{ Component, route }">
    <Suspense>
      <component :is="Component" :key="route.fullPath" />
    </Suspense>
  </template>
</router-tab>

Advanced Features

Tab Sorting

Enable drag-and-drop tab reordering with the sortable prop:

<router-tab 
  :sortable="true"
  @tab-sort="onTabSort"
  @tab-sorted="onTabSorted"
/>

Persistence Options

Fine-grained control over tab persistence:

<router-tab 
  :persistence="{
    cookieKey: 'my-app-tabs',
    storage: 'localStorage',
    debounceMs: 100,
    expiresInDays: 30,
    fallbackRoute: '/dashboard',
    serialize: (snapshot) => btoa(JSON.stringify(snapshot)),
    deserialize: (data) => JSON.parse(atob(data))
  }"
/>

Customising the Context Menu

<router-tab
  :contextMenu="[
    'refresh',
    'close',
    { id: 'closeOthers', label: 'Close All Others' },
    {
      id: 'openWindow',
      label: 'Open in new window',
      handler: ({ target }) => window.open(target.to, '_blank')
    }
  ]"
/>

Pass false to disable the context menu entirely.

Built-in Menu Items

• refresh - Refresh current tab
• refreshAll - Refresh all tabs
• close - Close current tab
• closeLefts - Close tabs to the left
• closeRights - Close tabs to the right
• closeOthers - Close all other tabs

Programmatic API

Access the router tabs controller to programmatically manage tabs.

Using the Composable

<script setup>
import { useRouterTabs } from 'vue3-router-tab'

const tabs = useRouterTabs()

// Available methods
tabs.openTab('/users')              // Open a tab
tabs.closeTab(tabId)                // Close a specific tab
tabs.refreshTab(tabId)              // Refresh a tab
tabs.refreshAll()                   // Refresh all tabs
tabs.closeAll()                     // Close all tabs
tabs.closeOthers(tabId)             // Close all except specified tab
</script>

Using Global Property

<script setup>
import { getCurrentInstance } from 'vue'

const instance = getCurrentInstance()
const tabs = instance?.appContext.config.globalProperties.$tabs

// Same methods available
tabs?.openTab('/dashboard')
tabs?.refreshTab('users-123')
</script>

Controller Methods

Example: Custom Tab Controls

<template>
  <div>
    <button @click="openDashboard">Open Dashboard</button>
    <button @click="refreshCurrent">Refresh Current</button>
    <button @click="closeAllTabs">Close All</button>
  </div>
</template>

<script setup>
import { useRouterTabs } from 'vue3-router-tab'
import { useRoute } from 'vue-router'

const tabs = useRouterTabs()
const route = useRoute()

function openDashboard() {
  tabs.openTab('/dashboard', true)
}

function refreshCurrent() {
  const currentTab = tabs.tabs.find(t => t.to.path === route.path)
  if (currentTab) {
    tabs.refreshTab(currentTab.id, true)
  }
}

function closeAllTabs() {
  tabs.closeAll({ force: true })
}
</script>

Tab State Access

<script setup>
import { useRouterTabs } from 'vue3-router-tab'

const controller = useRouterTabs()

</script>

Events

RouterTab emits events for tab interactions.

Available Events

Usage Example

<template>
  <router-tab 
    @tab-sort="onTabSort"
    @tab-sorted="onTabSorted"
  />
</template>

<script setup>
function onTabSort({ tab, index }) {
  console.log('Dragging tab:', tab.title, 'from index:', index)
}

function onTabSorted({ tab, fromIndex, toIndex }) {
  console.log('Tab moved:', tab.title)
  console.log('From:', fromIndex, 'To:', toIndex)
  
  // Save new order to backend
  saveTabOrder(tab, toIndex)
}
</script>

Slots

• start / end – positioned on either side of the tab list (ideal for toolbars or the <router-tabs> helper).
• default – routed content (rendered automatically by <router-tab>).

Styling

The package ships with its own CSS bundle (imported automatically). Override CSS custom properties or the router-tab__* classes to customize the appearance.

CSS Custom Properties

:root {
  /* Layout */
  --router-tab-header-height: 48px;
  --router-tab-sticky-top: 0px;
  --router-tab-header-z-index: 10;
  --router-tab-padding: 16px;

}

When router-tab is rendered below a fixed app header, set --router-tab-sticky-top so the sticky bar locks beneath that header instead of sliding under it:

<router-tab class="app-router-tab" />

.app-router-tab {
  --router-tab-sticky-top: var(--v-layout-top, 0px);
}

Custom Styles Example

/* Change tab height */
.router-tab__header {
  height: 56px;
}

/* Custom tab hover effect */
.router-tab__item:hover {
  background: linear-gradient(135deg, #667eea 0%, #764ba2 100%);
  color: white;
}

/* Custom active tab */
.router-tab__item.is-active {
  background: #4f46e5;
  border-radius: 8px 8px 0 0;
}

/* Custom close button */
.router-tab__item-close {
  border-radius: 4px;
}

/* Dark theme adjustments */
[data-theme="dark"] .router-tab {
  --router-tab-background: #1e293b;
  --router-tab-text: #f1f5f9;
  --router-tab-border: #334155;
}

Troubleshooting

Tab titles not updating

Problem: Tab title doesn't change when component state updates.

Solution: Ensure you're using reactive refs or computed properties:

<!-- ✅ Correct -->
<script setup>
const routeTabTitle = ref('My Page')  // Reactive
</script>

<!-- ❌ Wrong -->
<script setup>
const routeTabTitle = 'My Page'  // Plain string - won't update
</script>

Transitions not working

Problem: Page transitions don't show when refreshing tabs.

Solution: Make sure you're not using a custom default slot that overrides transitions. Remove the custom slot or include transition components:

<!-- ✅ Default behavior with transitions -->
<router-tab page-transition="router-tab-fade" />

<!-- ❌ Custom slot without transitions -->
<router-tab>
  <template #default="{ Component }">
    <component :is="Component" />  <!-- No transition! -->
  </template>
</router-tab>

<!-- ✅ Custom slot with transitions -->
<router-tab>
  <template #default="{ Component }">
    <transition name="router-tab-fade" mode="out-in">
      <component :is="Component" />
    </transition>
  </template>
</router-tab>

Tabs not persisting on refresh

Problem: Tabs are lost when refreshing the browser.

Solution: Add the cookie-key prop:

<router-tab cookie-key="my-app-tabs" />

Check that cookies are enabled in the browser and not being blocked.

KeepAlive not working

Problem: Component state is lost when switching tabs.

Solution: Ensure :keep-alive="true" (default) and components are properly keyed:

// In router config
meta: {
  keepAlive: true,  // Enable for this route
  key: 'fullPath'   // Unique key per instance
}

TypeScript errors

Problem: TypeScript shows errors for router tab properties.

Solution: Import types and use them:

import type { TabRecord, RouterTabsOptions } from 'vue3-router-tab'

const options: RouterTabsOptions = {
  keepAlive: true,
  maxAlive: 10
}
