# Inertia Vue Development
|
||||
|
||||
## When to Apply
|
||||
|
||||
Activate this skill when:
|
||||
|
||||
- Creating or modifying Vue page components for Inertia
|
||||
- Working with forms in Vue (using `<Form>`, `useForm`, or `useHttp`)
|
||||
- Implementing client-side navigation with `<Link>` or `router`
|
||||
- Using v3 features: deferred props, prefetching, optimistic updates, instant visits, layout props, HTTP requests, WhenVisible, InfiniteScroll, once props, flash data, or polling
|
||||
- Building Vue-specific features with the Inertia protocol
|
||||
|
||||
## Documentation
|
||||
|
||||
Use `search-docs` for detailed Inertia v3 Vue patterns and documentation.
|
||||
|
||||
## Basic Usage
|
||||
|
||||
### Page Components Location
|
||||
|
||||
Vue page components should be placed in the `resources/js/pages` directory.
|
||||
|
||||
### Page Component Structure
|
||||
|
||||
<!-- Basic Vue Page Component -->
|
||||
```vue
|
||||
<script setup>
|
||||
defineProps({
|
||||
users: Array
|
||||
})
|
||||
</script>
|
||||
|
||||
<template>
|
||||
<div>
|
||||
<h1>Users</h1>
|
||||
<ul>
|
||||
<li v-for="user in users" :key="user.id">
|
||||
{{ user.name }}
|
||||
</li>
|
||||
</ul>
|
||||
</div>
|
||||
</template>
|
||||
```
|
||||
|
||||
## Client-Side Navigation
|
||||
|
||||
### Basic Link Component
|
||||
|
||||
Use `<Link>` for client-side navigation instead of traditional `<a>` tags:
|
||||
|
||||
<!-- Inertia Vue Navigation -->
|
||||
```vue
|
||||
<script setup>
|
||||
import { Link } from '@inertiajs/vue3'
|
||||
</script>
|
||||
|
||||
<template>
|
||||
<div>
|
||||
<Link href="/">Home</Link>
|
||||
<Link href="/users">Users</Link>
|
||||
<Link :href="`/users/${user.id}`">View User</Link>
|
||||
</div>
|
||||
</template>
|
||||
```
|
||||
|
||||
### Link with Method
|
||||
|
||||
<!-- Link with POST Method -->
|
||||
```vue
|
||||
<script setup>
|
||||
import { Link } from '@inertiajs/vue3'
|
||||
</script>
|
||||
|
||||
<template>
|
||||
<Link href="/logout" method="post" as="button">
|
||||
Logout
|
||||
</Link>
|
||||
</template>
|
||||
```
|
||||
|
||||
### Prefetching
|
||||
|
||||
Prefetch pages to improve perceived performance:
|
||||
|
||||
<!-- Prefetch on Hover -->
|
||||
```vue
|
||||
<script setup>
|
||||
import { Link } from '@inertiajs/vue3'
|
||||
</script>
|
||||
|
||||
<template>
|
||||
<Link href="/users" prefetch>
|
||||
Users
|
||||
</Link>
|
||||
</template>
|
||||
```
|
||||
|
||||
### Programmatic Navigation
|
||||
|
||||
<!-- Router Visit -->
|
||||
```vue
|
||||
<script setup>
|
||||
import { router } from '@inertiajs/vue3'
|
||||
|
||||
function handleClick() {
|
||||
router.visit('/users')
|
||||
}
|
||||
|
||||
// Or with options
|
||||
function createUser() {
|
||||
router.visit('/users', {
|
||||
method: 'post',
|
||||
data: { name: 'John' },
|
||||
onSuccess: () => console.log('Done'),
|
||||
})
|
||||
}
|
||||
</script>
|
||||
|
||||
<template>
|
||||
<Link href="/users">Users</Link>
|
||||
<Link href="/logout" method="post" as="button">Logout</Link>
|
||||
</template>
|
||||
```
|
||||
|
||||
## Form Handling
|
||||
|
||||
### Form Component (Recommended)
|
||||
|
||||
The recommended way to build forms is with the `<Form>` component:
|
||||
|
||||
<!-- Form Component Example -->
|
||||
```vue
|
||||
<script setup>
|
||||
import { Form } from '@inertiajs/vue3'
|
||||
</script>
|
||||
|
||||
<template>
|
||||
<Form action="/users" method="post" #default="{ errors, processing, wasSuccessful }">
|
||||
<input type="text" name="name" />
|
||||
<div v-if="errors.name">{{ errors.name }}</div>
|
||||
|
||||
<input type="email" name="email" />
|
||||
<div v-if="errors.email">{{ errors.email }}</div>
|
||||
|
||||
<button type="submit" :disabled="processing">
|
||||
{{ processing ? 'Creating...' : 'Create User' }}
|
||||
</button>
|
||||
|
||||
<div v-if="wasSuccessful">User created!</div>
|
||||
</Form>
|
||||
</template>
|
||||
```
|
||||
|
||||
### Form Component With All Props
|
||||
|
||||
<!-- Form Component Full Example -->
|
||||
```vue
|
||||
<script setup>
|
||||
import { Form } from '@inertiajs/vue3'
|
||||
</script>
|
||||
|
||||
<template>
|
||||
<Form
|
||||
action="/users"
|
||||
method="post"
|
||||
#default="{
|
||||
errors,
|
||||
hasErrors,
|
||||
processing,
|
||||
progress,
|
||||
wasSuccessful,
|
||||
recentlySuccessful,
|
||||
setError,
|
||||
clearErrors,
|
||||
resetAndClearErrors,
|
||||
defaults,
|
||||
isDirty,
|
||||
reset,
|
||||
submit
|
||||
}"
|
||||
>
|
||||
<input type="text" name="name" :value="defaults.name" />
|
||||
<div v-if="errors.name">{{ errors.name }}</div>
|
||||
|
||||
<button type="submit" :disabled="processing">
|
||||
{{ processing ? 'Saving...' : 'Save' }}
|
||||
</button>
|
||||
|
||||
<progress v-if="progress" :value="progress.percentage" max="100">
|
||||
{{ progress.percentage }}%
|
||||
</progress>
|
||||
|
||||
<div v-if="wasSuccessful">Saved!</div>
|
||||
</Form>
|
||||
</template>
|
||||
```
|
||||
|
||||
### Form Component Reset Props
|
||||
|
||||
The `<Form>` component supports automatic resetting:
|
||||
|
||||
- `resetOnError` - Reset form data when the request fails
|
||||
- `resetOnSuccess` - Reset form data when the request succeeds
|
||||
- `setDefaultsOnSuccess` - Update default values on success
|
||||
|
||||
Use the `search-docs` tool with a query of `form component resetting` for detailed guidance.
|
||||
|
||||
<!-- Form with Reset Props -->
|
||||
```vue
|
||||
<script setup>
|
||||
import { Form } from '@inertiajs/vue3'
|
||||
</script>
|
||||
|
||||
<template>
|
||||
<Form
|
||||
action="/users"
|
||||
method="post"
|
||||
reset-on-success
|
||||
set-defaults-on-success
|
||||
#default="{ errors, processing, wasSuccessful }"
|
||||
>
|
||||
<input type="text" name="name" />
|
||||
<div v-if="errors.name">{{ errors.name }}</div>
|
||||
|
||||
<button type="submit" :disabled="processing">
|
||||
Submit
|
||||
</button>
|
||||
</Form>
|
||||
</template>
|
||||
```
|
||||
|
||||
Forms can also be built using the `useForm` composable for more programmatic control. Use the `search-docs` tool with a query of `useForm helper` for guidance.
|
||||
|
||||
### `useForm` Composable
|
||||
|
||||
For more programmatic control or to follow existing conventions, use the `useForm` composable:
|
||||
|
||||
<!-- useForm Composable Example -->
|
||||
```vue
|
||||
<script setup>
|
||||
import { useForm } from '@inertiajs/vue3'
|
||||
|
||||
const form = useForm({
|
||||
name: '',
|
||||
email: '',
|
||||
password: '',
|
||||
})
|
||||
|
||||
function submit() {
|
||||
form.post('/users', {
|
||||
onSuccess: () => form.reset('password'),
|
||||
})
|
||||
}
|
||||
</script>
|
||||
|
||||
<template>
|
||||
<form @submit.prevent="submit">
|
||||
<input type="text" v-model="form.name" />
|
||||
<div v-if="form.errors.name">{{ form.errors.name }}</div>
|
||||
|
||||
<input type="email" v-model="form.email" />
|
||||
<div v-if="form.errors.email">{{ form.errors.email }}</div>
|
||||
|
||||
<input type="password" v-model="form.password" />
|
||||
<div v-if="form.errors.password">{{ form.errors.password }}</div>
|
||||
|
||||
<button type="submit" :disabled="form.processing">
|
||||
Create User
|
||||
</button>
|
||||
</form>
|
||||
</template>
|
||||
```
|
||||
|
||||
## Inertia v3 Features
|
||||
|
||||
### HTTP Requests
|
||||
|
||||
Use the `useHttp` hook for standalone HTTP requests that do not trigger Inertia page visits. It provides the same developer experience as `useForm`, but for plain JSON endpoints.
|
||||
|
||||
<!-- useHttp Example -->
|
||||
```vue
|
||||
<script setup>
|
||||
import { useHttp } from '@inertiajs/vue3'
|
||||
|
||||
const http = useHttp({
|
||||
query: '',
|
||||
})
|
||||
|
||||
function search() {
|
||||
http.get('/api/search', {
|
||||
onSuccess: (response) => {
|
||||
console.log(response)
|
||||
},
|
||||
})
|
||||
}
|
||||
</script>
|
||||
|
||||
<template>
|
||||
<input v-model="http.query" @input="search" />
|
||||
<div v-if="http.processing">Searching...</div>
|
||||
</template>
|
||||
```
|
||||
|
||||
### Optimistic Updates
|
||||
|
||||
Apply data changes instantly before the server responds, with automatic rollback on failure:
|
||||
|
||||
<!-- Optimistic Update with Router -->
|
||||
```vue
|
||||
<script setup>
|
||||
import { router } from '@inertiajs/vue3'
|
||||
|
||||
function like(post) {
|
||||
router.optimistic((props) => ({
|
||||
post: {
|
||||
...props.post,
|
||||
likes: props.post.likes + 1,
|
||||
},
|
||||
})).post(`/posts/${post.id}/like`)
|
||||
}
|
||||
</script>
|
||||
```
|
||||
|
||||
Optimistic updates also work with `useForm` and the `<Form>` component:
|
||||
|
||||
<!-- Optimistic Update with Form Component -->
|
||||
```vue
|
||||
<template>
|
||||
<Form
|
||||
action="/todos"
|
||||
method="post"
|
||||
:optimistic="(props, data) => ({
|
||||
todos: [...props.todos, { id: Date.now(), name: data.name, done: false }],
|
||||
})"
|
||||
>
|
||||
<input type="text" name="name" />
|
||||
<button type="submit">Add Todo</button>
|
||||
</Form>
|
||||
</template>
|
||||
```
|
||||
|
||||
### Instant Visits
|
||||
|
||||
Navigate to a new page immediately without waiting for the server response. The target component renders right away with shared props, while page-specific props load in the background.
|
||||
|
||||
<!-- Instant Visit with Link -->
|
||||
```vue
|
||||
<script setup>
|
||||
import { Link } from '@inertiajs/vue3'
|
||||
</script>
|
||||
|
||||
<template>
|
||||
<Link href="/dashboard" component="Dashboard">Dashboard</Link>
|
||||
|
||||
<Link
|
||||
href="/posts/1"
|
||||
component="Posts/Show"
|
||||
:page-props="{ post: { id: 1, title: 'My Post' } }"
|
||||
>
|
||||
View Post
|
||||
</Link>
|
||||
</template>
|
||||
```
|
||||
|
||||
### Layout Props
|
||||
|
||||
Share dynamic data between pages and persistent layouts:
|
||||
|
||||
<!-- Layout Props in Layout -->
|
||||
```vue
|
||||
<script setup>
|
||||
withDefaults(defineProps({
|
||||
title: String,
|
||||
showSidebar: Boolean,
|
||||
}), {
|
||||
title: 'My App',
|
||||
showSidebar: true,
|
||||
})
|
||||
</script>
|
||||
|
||||
<template>
|
||||
<header>{{ title }}</header>
|
||||
<aside v-if="showSidebar">Sidebar</aside>
|
||||
<main>
|
||||
<slot />
|
||||
</main>
|
||||
</template>
|
||||
```
|
||||
|
||||
<!-- Setting Layout Props from Page -->
|
||||
```vue
|
||||
<script setup>
|
||||
import { setLayoutProps } from '@inertiajs/vue3'
|
||||
|
||||
setLayoutProps({
|
||||
title: 'Dashboard',
|
||||
showSidebar: false,
|
||||
})
|
||||
</script>
|
||||
|
||||
<template>
|
||||
<h1>Dashboard</h1>
|
||||
</template>
|
||||
```
|
||||
|
||||
### Deferred Props
|
||||
|
||||
Use deferred props to load data after initial page render:
|
||||
|
||||
<!-- Deferred Props with Empty State -->
|
||||
```vue
|
||||
<script setup>
|
||||
defineProps({
|
||||
users: Array
|
||||
})
|
||||
</script>
|
||||
|
||||
<template>
|
||||
<div>
|
||||
<h1>Users</h1>
|
||||
<div v-if="!users" class="animate-pulse">
|
||||
<div class="h-4 bg-gray-200 rounded w-3/4 mb-2"></div>
|
||||
<div class="h-4 bg-gray-200 rounded w-1/2"></div>
|
||||
</div>
|
||||
<ul v-else>
|
||||
<li v-for="user in users" :key="user.id">
|
||||
{{ user.name }}
|
||||
</li>
|
||||
</ul>
|
||||
</div>
|
||||
</template>
|
||||
```
|
||||
|
||||
### Polling
|
||||
|
||||
Use the `usePoll` composable to automatically refresh data at intervals. It handles cleanup on unmount and throttles polling when the tab is inactive.
|
||||
|
||||
<!-- Basic Polling -->
|
||||
```vue
|
||||
<script setup>
|
||||
import { usePoll } from '@inertiajs/vue3'
|
||||
|
||||
defineProps({
|
||||
stats: Object
|
||||
})
|
||||
|
||||
usePoll(5000)
|
||||
</script>
|
||||
|
||||
<template>
|
||||
<div>
|
||||
<h1>Dashboard</h1>
|
||||
<div>Active Users: {{ stats.activeUsers }}</div>
|
||||
</div>
|
||||
</template>
|
||||
```
|
||||
|
||||
<!-- Polling With Request Options and Manual Control -->
|
||||
```vue
|
||||
<script setup>
|
||||
import { usePoll } from '@inertiajs/vue3'
|
||||
|
||||
defineProps({
|
||||
stats: Object
|
||||
})
|
||||
|
||||
const { start, stop } = usePoll(5000, {
|
||||
only: ['stats'],
|
||||
onStart() {
|
||||
console.log('Polling request started')
|
||||
},
|
||||
onFinish() {
|
||||
console.log('Polling request finished')
|
||||
},
|
||||
}, {
|
||||
autoStart: false,
|
||||
keepAlive: true,
|
||||
})
|
||||
</script>
|
||||
|
||||
<template>
|
||||
<div>
|
||||
<h1>Dashboard</h1>
|
||||
<div>Active Users: {{ stats.activeUsers }}</div>
|
||||
<button @click="start">Start Polling</button>
|
||||
<button @click="stop">Stop Polling</button>
|
||||
</div>
|
||||
</template>
|
||||
```
|
||||
|
||||
- `autoStart` (default `true`) - set to `false` to start polling manually via the returned `start()` function
|
||||
- `keepAlive` (default `false`) - set to `true` to prevent throttling when the browser tab is inactive
|
||||
|
||||
### WhenVisible
|
||||
|
||||
Lazy-load a prop when an element scrolls into view. Useful for deferring expensive data that sits below the fold:
|
||||
|
||||
<!-- WhenVisible Example -->
|
||||
```vue
|
||||
<script setup>
|
||||
import { WhenVisible } from '@inertiajs/vue3'
|
||||
|
||||
defineProps({
|
||||
stats: Object
|
||||
})
|
||||
</script>
|
||||
|
||||
<template>
|
||||
<div>
|
||||
<h1>Dashboard</h1>
|
||||
|
||||
<WhenVisible data="stats" :buffer="200">
|
||||
<template #fallback>
|
||||
<div class="animate-pulse">Loading stats...</div>
|
||||
</template>
|
||||
|
||||
<template #default="{ fetching }">
|
||||
<div>
|
||||
<p>Total Users: {{ stats.total_users }}</p>
|
||||
<p>Revenue: {{ stats.revenue }}</p>
|
||||
<span v-if="fetching">Refreshing...</span>
|
||||
</div>
|
||||
</template>
|
||||
</WhenVisible>
|
||||
</div>
|
||||
</template>
|
||||
```
|
||||
|
||||
### InfiniteScroll
|
||||
|
||||
Automatically load additional pages of paginated data as users scroll:
|
||||
|
||||
<!-- InfiniteScroll Example -->
|
||||
```vue
|
||||
<script setup>
|
||||
import { InfiniteScroll } from '@inertiajs/vue3'
|
||||
|
||||
defineProps({
|
||||
users: Object
|
||||
})
|
||||
</script>
|
||||
|
||||
<template>
|
||||
<InfiniteScroll data="users">
|
||||
<div v-for="user in users.data" :key="user.id">
|
||||
{{ user.name }}
|
||||
</div>
|
||||
</InfiniteScroll>
|
||||
</template>
|
||||
```
|
||||
|
||||
The server must use `Inertia::scroll()` to configure the paginated data. Use the `search-docs` tool with a query of `infinite scroll` for detailed guidance on buffers, manual loading, reverse mode, and custom trigger elements.
|
||||
|
||||
## Server-Side Patterns
|
||||
|
||||
Server-side patterns (Inertia::render, props, middleware) are covered in inertia-laravel guidelines.
|
||||
|
||||
## Common Pitfalls
|
||||
|
||||
- Using traditional `<a>` links instead of Inertia's `<Link>` component (breaks SPA behavior)
|
||||
- Forgetting that Vue components must have a single root element
|
||||
- Forgetting to add loading states (skeleton screens) when using deferred props
|
||||
- Not handling the `undefined` state of deferred props before data loads
|
||||
- Using `<form>` without preventing default submission (use `<Form>` component or `@submit.prevent`)
|
||||
- Forgetting to check if `<Form>` component is available in your Inertia version
|
||||
- Using `router.cancel()` instead of `router.cancelAll()` (v3 breaking change)
|
||||
- Using `router.on('invalid', ...)` or `router.on('exception', ...)` instead of the renamed `httpException` and `networkError` events
