Inertia React Development

When to Apply

Activate this skill when:

• Creating or modifying React page components for Inertia
• Working with forms in React (using <Form> or useForm)
• Implementing client-side navigation with <Link> or router
• Using v2 features: deferred props, prefetching, WhenVisible, InfiniteScroll, once props, flash data, or polling
• Building React-specific features with the Inertia protocol

Documentation

Use search-docs for detailed Inertia v2 React patterns and documentation.

Basic Usage

Page Components Location

React page components should be placed in the resources/js/pages directory.

Page Component Structure

export default function UsersIndex({ users }) {
    return (
        <div>
            <h1>Users</h1>
            <ul>
                {users.map(user => <li key={user.id}>{user.name}</li>)}
            </ul>
        </div>
    )
}

Client-Side Navigation

Basic Link Component

Use <Link> for client-side navigation instead of traditional <a> tags:

import { Link, router } from '@inertiajs/react'

<Link href="/">Home</Link>
<Link href="/users">Users</Link>
<Link href={`/users/${user.id}`}>View User</Link>

Link with Method

import { Link } from '@inertiajs/react'

<Link href="/logout" method="post" as="button">
    Logout
</Link>

Prefetching

Prefetch pages to improve perceived performance:

import { Link } from '@inertiajs/react'

<Link href="/users" prefetch>
    Users
</Link>

Programmatic Navigation

import { router } from '@inertiajs/react'

function handleClick() {
    router.visit('/users')
}

// Or with options
router.visit('/users', {
    method: 'post',
    data: { name: 'John' },
    onSuccess: () => console.log('Success!'),
})

Form Handling

Form Component (Recommended)

The recommended way to build forms is with the <Form> component:

import { Form } from '@inertiajs/react'

export default function CreateUser() {
    return (
        <Form action="/users" method="post">
            {({ errors, processing, wasSuccessful }) => (
                <>
                    <input type="text" name="name" />
                    {errors.name && <div>{errors.name}</div>}

                    <input type="email" name="email" />
                    {errors.email && <div>{errors.email}</div>}

                    <button type="submit" disabled={processing}>
                        {processing ? 'Creating...' : 'Create User'}
                    </button>

                    {wasSuccessful && <div>User created!</div>}
                </>
            )}
        </Form>
    )
}

Form Component With All Props

import { Form } from '@inertiajs/react'

<Form action="/users" method="post">
    {({
        errors,
        hasErrors,
        processing,
        progress,
        wasSuccessful,
        recentlySuccessful,
        clearErrors,
        resetAndClearErrors,
        defaults,
        isDirty,
        reset,
        submit
    }) => (
        <>
            <input type="text" name="name" defaultValue={defaults.name} />
            {errors.name && <div>{errors.name}</div>}

            <button type="submit" disabled={processing}>
                {processing ? 'Saving...' : 'Save'}
            </button>

            {progress && (
                <progress value={progress.percentage} max="100">
                    {progress.percentage}%
                </progress>
            )}

            {wasSuccessful && <div>Saved!</div>}
        </>
    )}
</Form>

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.

import { Form } from '@inertiajs/react'

<Form
    action="/users"
    method="post"
    resetOnSuccess
    setDefaultsOnSuccess
>
    {({ errors, processing, wasSuccessful }) => (
        <>
            <input type="text" name="name" />
            {errors.name && <div>{errors.name}</div>}

            <button type="submit" disabled={processing}>
                Submit
            </button>
        </>
    )}
</Form>

Forms can also be built using the useForm helper for more programmatic control. Use the search-docs tool with a query of useForm helper for guidance.

useForm Hook

For more programmatic control or to follow existing conventions, use the useForm hook:

import { useForm } from '@inertiajs/react'

export default function CreateUser() {
    const { data, setData, post, processing, errors, reset } = useForm({
        name: '',
        email: '',
        password: '',
    })

    function submit(e) {
        e.preventDefault()
        post('/users', {
            onSuccess: () => reset('password'),
        })
    }

    return (
        <form onSubmit={submit}>
            <input
                type="text"
                value={data.name}
                onChange={e => setData('name', e.target.value)}
            />
            {errors.name && <div>{errors.name}</div>}

            <input
                type="email"
                value={data.email}
                onChange={e => setData('email', e.target.value)}
            />
            {errors.email && <div>{errors.email}</div>}

            <input
                type="password"
                value={data.password}
                onChange={e => setData('password', e.target.value)}
            />
            {errors.password && <div>{errors.password}</div>}

            <button type="submit" disabled={processing}>
                Create User
            </button>
        </form>
    )
}

Inertia v2 Features

Deferred Props

Use deferred props to load data after initial page render:

export default function UsersIndex({ users }) {
    // users will be undefined initially, then populated
    return (
        <div>
            <h1>Users</h1>
            {!users ? (
                <div className="animate-pulse">
                    <div className="h-4 bg-gray-200 rounded w-3/4 mb-2"></div>
                    <div className="h-4 bg-gray-200 rounded w-1/2"></div>
                </div>
            ) : (
                <ul>
                    {users.map(user => (
                        <li key={user.id}>{user.name}</li>
                    ))}
                </ul>
            )}
        </div>
    )
}

Polling

Use the usePoll hook to automatically refresh data at intervals. It handles cleanup on unmount and throttles polling when the tab is inactive.

import { usePoll } from '@inertiajs/react'

export default function Dashboard({ stats }) {
    usePoll(5000)

    return (
        <div>
            <h1>Dashboard</h1>
            <div>Active Users: {stats.activeUsers}</div>
        </div>
    )
}

import { usePoll } from '@inertiajs/react'

export default function Dashboard({ stats }) {
    const { start, stop } = usePoll(5000, {
        only: ['stats'],
        onStart() {
            console.log('Polling request started')
        },
        onFinish() {
            console.log('Polling request finished')
        },
    }, {
        autoStart: false,
        keepAlive: true,
    })

    return (
        <div>
            <h1>Dashboard</h1>
            <div>Active Users: {stats.activeUsers}</div>
            <button onClick={start}>Start Polling</button>
            <button onClick={stop}>Stop Polling</button>
        </div>
    )
}

• 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:

import { WhenVisible } from '@inertiajs/react'

export default function Dashboard({ stats }) {
    return (
        <div>
            <h1>Dashboard</h1>

            <WhenVisible data="stats" buffer={200} fallback={<div className="animate-pulse">Loading stats...</div>}>
                {({ fetching }) => (
                    <div>
                        <p>Total Users: {stats.total_users}</p>
                        <p>Revenue: {stats.revenue}</p>
                        {fetching && <span>Refreshing...</span>}
                    </div>
                )}
            </WhenVisible>
        </div>
    )
}

InfiniteScroll

Automatically load additional pages of paginated data as users scroll:

import { InfiniteScroll } from '@inertiajs/react'

export default function Users({ users }) {
    return (
        <InfiniteScroll data="users">
            {users.data.map(user => (
                <div key={user.id}>{user.name}</div>
            ))}
        </InfiniteScroll>
    )
}

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.

Common Pitfalls

• Using traditional <a> links instead of Inertia's <Link> component (breaks SPA behavior)
• 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 e.preventDefault())
• Forgetting to check if <Form> component is available in your Inertia version
