app/Http/Livewire/Search.php

<?php

namespace App\Http\Livewire;

use Livewire\Component;
use App\User;

class Search extends Component
{
    public $perPage = 10;
    protected $listeners = [
        'load-more' => 'loadMore'
    ];

    public function loadMore()
    {
        $this->perPage = $this->perPage + 5;
    }

    public function render()
    {
        $users = User::latest()->paginate($this->perPage);
        $this->emit('userStore');
        return view('livewire.users',['users' => $users]);

<?php

namespace App\Http\Livewire;

use Livewire\Component;

use App\User;

class Search extends Component

{

public $perPage = 10;

protected $listeners = [

'load-more' => 'loadMore'

];

public function loadMore()

{

$this->perPage = $this->perPage + 5;

}

public function render()

{

$users = User::latest()->paginate($this->perPage);

$this->emit('userStore');

return view('livewire.users',['users' => $users]);

}

Step 7: Create Route
Add the following route code in the “routes/web.php” file.

<?php
 
/*
|--------------------------------------------------------------------------
| 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::view('search','livewire.home');

<?php

|--------------------------------------------------------------------------

| 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::view('search','livewire.home');

Step 8: Create Blade Files

So finally, first we will open the home.blade.php and search.blade.php files and after then paste the following code.
resources/views/livewire/home.blade.php

<html>
<head>
    <title>Laravel 7 Livewire Load More Data From Scratch - XpertPhp</title>
    <script src="{{ asset('js/app.js') }}" defer></script>

                        @endif
                        @livewire('search')

                </div>
            </div>
        </div>
    </div>
    @livewireScripts
    <script type="text/javascript">
        window.onscroll = function(ev) {
            if ((window.innerHeight + window.scrollY) >= document.body.offsetHeight) {
                window.livewire.emit('load-more');
            }
        };
