Seamless Data Loading with Inertia 2.2 Infinite Scroll

Overview

Modern applications often struggle with large datasets. Loading 5,000 log entries at once creates massive latency and a poor user experience. While standard pagination solves the performance issue, it breaks the fluid experience users expect. The Inertia 2.2 InfiniteScroll component bridges this gap, providing a high-performance, bidirectional scrolling interface with minimal boilerplate.

Prerequisites

To follow along, you should be comfortable with Laravel and the Inertia.js ecosystem. You will need a project running Inertia 2.2 or higher and a backend controller returning a standard Laravel paginated collection.

Key Libraries & Tools

• Laravel: The backend framework handling data fetching and pagination logic.
• Inertia.js: The glue between your PHP backend and JavaScript frontend.
• InfiniteScroll: The specific UI component for managing scroll-triggered requests.

Code Walkthrough

Step 1: Server-Side Preparation

Instead of passing a raw collection, use the Inertia::scroll method in your controller. This helper tells the frontend how to handle appending or prepending data.

return inertia('Logs/Index', [
    'entries' => Inertia::scroll(Log::paginate(15))
]);

Step 2: Implementing the Frontend Component

Wrap your loop with the InfiniteScroll component. You must point the data prop to your collection name.

<template>
    <InfiniteScroll :data="entries">
        <template #default="{ item }">
            <div :key="item.id">{{ item.message }}</div>
        </template>
    </InfiniteScroll>
</template>

Step 3: Manual Control and Slots

If you need to show a footer or limit automatic fetching, use the manual-after prop. You can then use the #next or #previous slots to provide custom triggers.

<InfiniteScroll :data="entries" :manual-after="5">
    <template #next="{ hasMore, fetch, loading }">
        <button v-if="hasMore" @click="fetch" :disabled="loading">
            Load More
        </button>
    </template>
</InfiniteScroll>

Syntax Notes

The component utilizes scoped slots to expose internal state, such as loading, fetch, and hasMore. This allows you to build completely custom UI triggers while the component manages the network logic and URL synchronization.

Practical Examples

This technique is ideal for activity feeds, audit logs, or e-commerce product grids where users might want to share a specific location in a list. Because the component updates the URL as you scroll, bookmarks remain valid for specific pages.

Tips & Gotchas

Always ensure your frontend data types reflect the change from a flat array to a paginated object. When switching to pagination, your data will now live under a .data property, which often requires a quick update to your type definitions or loop logic to prevent undefined errors.
