Inertia.js
Modern monolith framework for building SPAs without APIs. Combine server-side framework power with React/Vue/Svelte frontends.
Core Concept
Inertia replaces your view layer - controllers return JavaScript page components instead of server-side templates. The <Link> component intercepts clicks for XHR visits, providing SPA experience without full page reloads.
Quick Reference
Basic Page Structure
<script setup>
import Layout from './Layout'
import { Head } from '@inertiajs/vue3'
defineProps({ user: Object })
</script>
<template>
<Layout>
<Head title="Welcome" />
<h1>Welcome {{ user.name }}</h1>
</Layout>
</template>Navigation
<Link href="/users">Users</Link>
<Link href="/logout" method="post" as="button">Logout</Link>
<Link href="/search" :data="{ query }" preserve-state>Search</Link>Form Submission
<!-- Simple Form Component -->
<Form action="/users" method="post">
<input type="text" name="name" />
<button type="submit">Create</button>
</Form>
<!-- useForm Hook -->
<script setup>
import { useForm } from '@inertiajs/vue3'
const form = useForm({ name: '', email: '' })
function submit() { form.post('/users') }

Common Patterns
Displaying Validation Errors
<div v-if="errors.email">{{ errors.email }}</div>Accessing Shared Data
<script setup>
import { usePage } from '@inertiajs/vue3'
const page = usePage()
const user = computed(() => page.props.auth?.user)
</script>Preserving State/Scroll
<Link href="/form" preserve-state preserve-scroll>Edit</Link>Partial Reloads
<Link :only="['users']">Refresh Users</Link>
router.visit('/users', { only: ['users'] })Framework Support
