Laravel 10 Auto Load More Data on Page Scroll using AJAX Example

Hello Folks,

This example is focused on laravel 10 load more on scroll. Here you will learn auto load more data on page scroll laravel 10. In this article, we will implement a laravel 10 auto load more on scroll with ajax. This article will give you a simple example of auto load more data on page scroll in laravel 10 and ajax.

Auto Load More Data on Page Scroll with AJAX is a technique used in web development to enhance the user experience by dynamically loading additional content as the user scrolls down a web page. This technique is particularly useful when dealing with pages that contain large amounts of data or content that is loaded from a remote server. The technique involves the use of Asynchronous JavaScript and XML (AJAX) to retrieve additional data from the server without requiring a page refresh. When the user scrolls to the bottom of the page, JavaScript code detects this and sends an AJAX request to the server for additional data. The response is then appended to the existing content on the page, allowing the user to seamlessly continue browsing without having to click a "next page" button or wait for a page refresh.

Implementing this technique can improve the performance of a web page by reducing the amount of data that needs to be loaded initially, which can improve page load times and reduce server load. It can also provide a more engaging and seamless user experience by eliminating the need for the user to navigate between multiple pages or wait for content to load.

In this example, we will create a posts table using migration. Then, we will create a data model for the posts and a factory class to create dummy post data. Finally, we will create a route to load posts and write the code for auto-loading more data on page scroll using AJAX. Let's take a look at a simple step-by-step example.

Step 1: Install Laravel

This step is not required; however, if you have not created the laravel app, then you may go ahead and execute the below command:

composer create-project laravel/laravel example-app

Step 2 : Database Configuration

In this step, we require to make database configuration, you have to add following details on your .env file.

1.Database Username

2.Database Password

3.Database Name

In .env file also available host and port details, you can configure all details as in your system, So you can put like as bellow:

.env

DB_HOST=localhost
DB_DATABASE=homestead
DB_USERNAME=homestead
DB_PASSWORD=secret

Step 3: Create Migration

here, we will create new migration for adding new table posts in users table. so let's run bellow command:

php artisan make:migration create_posts_table

After this command you will find one file in following path "database/migrations" and you have to put bellow code in your migration file for create products table.

<?php
  
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
  
return new class extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('posts', function (Blueprint $table) {
            $table->id();
            $table->string('title');
            $table->string('slug');
            $table->text('body');
            $table->timestamps();
        });
    }
    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('posts');
    }
};

Now you have to run this migration by following command:

php artisan migrate

Step 4: Create Model

After create "posts" table you should create Post model for posts, so first create file in this path app/Models/Post.php and put bellow content in Post.php file:

app/Models/Post.php

<?php
    
namespace App\Models;
    
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
    
class Post extends Model
{
    use HasFactory;
   
    /**
     * Write code on Method
     *
     * @return response()
     */
    protected $fillable = [
        'title', 'body', 'slug'
    ];
}

Step 5: Create Factory Class

This step explains how to generate dummy data using factory; this data loads dynamically on page scroll:

php artisan make:factory PostFactory --model=Post

Further, put the below code in database\factories\PostFactory.php:

database\factories\PostFactory.php

<?php
    
namespace Database\Factories;
    
use Illuminate\Database\Eloquent\Factories\Factory;
use App\Models\Post;
use Illuminate\Support\Str;
    
/**
 * @extends \Illuminate\Database\Eloquent\Factories\Factory<\App\Models\Post>
 */
class PostFactory extends Factory
{
    /**
     * The name of the factory's corresponding model.
     *
     * @var string
     */
    protected $model = Post::class;
      
    /**
     * Define the model's default state.
     *
     * @return array
     */
    public function definition(): array
    {
        return [
            'title' => $this->faker->text(),
            'slug' => Str::slug($this->faker->text()),
            'body' => $this->faker->paragraph()
        ];
    }
}

Open terminal, execute the below commands to generate the test data:

php artisan tinker

Post::factory()->count(20)->create()

Step 6: Create Route

In this is step we need to create routes for display posts and getting posts. so open your "routes/web.php" file and add following route.

routes/web.php

<?php
  
use Illuminate\Support\Facades\Route;
  
use App\Http\Controllers\PostController;
   
/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/
    
Route::get('posts',[PostController::class,'index'])->name('posts.index');

Step 7: Create Controller

Here,we require to create new controller PostController with index method to display posts view and return data. So let's put bellow code.

app/Http/Controllers/PostController.php

<?php
     
namespace App\Http\Controllers;
     
use Illuminate\Http\Request;
use App\Models\Post;
     
class PostController extends Controller
{
  
    /**
     * Write code on Method
     *
     * @return response()
     */
    public function index(Request $request)
    {
        $posts = Post::paginate(10);
  
        if ($request->ajax()) {
            $view = view('data', compact('posts'))->render();
  
            return response()->json(['html' => $view]);
        }
  
        return view('posts', compact('posts'));
    }
}

Step 8: Create View File

In Last step, let's create posts.blade.php and data.blade.php for display posts list and put following code:

resources/views/posts.blade.php

<!DOCTYPE html>
<html lang="{{ str_replace('_', '-', app()->getLocale()) }}">
<head>
    <meta name="csrf-token" content="{{ csrf_token() }}">
    <title>Laravel Load More on Scroll Example - ItSolutionStuff.com</title>
    <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap@5.0.0-beta1/dist/css/bootstrap.min.css">
</head>
<body>
      
<div class="container mt-5" style="max-width: 750px">
  
    <h1>Laravel Load More on Scroll Example - ItSolutionStuff.com</h1>
  
    <div id="data-wrapper">
        @include('data')

                    from="0 50 50" to="360 50 50" repeatCount="indefinite" />
            </path>
        </svg>
    </div>
</div>
  
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script>
    var ENDPOINT = "{{ route('posts.index') }}";
    var page = 1;
  
    /*------------------------------------------
    --------------------------------------------
    Call on Scroll
    --------------------------------------------
    --------------------------------------------*/
    $(window).scroll(function () {
        if ($(window).scrollTop() + $(window).height() >= ($(document).height() - 20)) {
            page++;
            infinteLoadMore(page);
        }
    });
  
    /*------------------------------------------
    --------------------------------------------
    call infinteLoadMore()
    --------------------------------------------
    --------------------------------------------*/
    function infinteLoadMore(page) {
        $.ajax({
                url: ENDPOINT + "?page=" + page,
                datatype: "html",
                type: "get",
                beforeSend: function () {
                    $('.auto-load').show();
                }
            })
            .done(function (response) {
                if (response.html == '') {
                    $('.auto-load').html("We don't have more data to display :(");
                    return;
                }
  
                $('.auto-load').hide();
                $("#data-wrapper").append(response.html);
            })
            .fail(function (jqXHR, ajaxOptions, thrownError) {
                console.log('Server error occured');
            });
    }
</script>
</body>
</html>

resources/views/data.blade.php

@foreach ($posts as $post)
<div class="card mb-2"> 
    <div class="card-body">{{ $post->id }} 
        <h5 class="card-title">{{ $post->title }}</h5>
