How to create a custom auth provider in Laravel

Imagine the following situation: in an API implemented in PHP and Laravel, we need to create an entity for users who are authenticated in another specific API, which provides only user data and not an authentication token.

This is a fairly common situation for most developers these days, and if you haven't experienced it yet, rest assured, that day will come soon.

Well, in this case, it's recommended that, in addition to implementing an internal authentication layer without using the User model, we also implement authentication token generation and user session management.

So, what we'll use is:

PHP 8.x;

Laravel and Bootstrap paginator with filters

Problem:

When creating a record listing page with filters using Laravel and Blade with Bootstrap 4, we encounter the following situation:

The pagination works perfectly, but after applying a filter and changing the page, the previously applied filter is lost. This occurs because Laravel's pagination already includes page links in the query parameters on the front-end, overriding the filters that are currently in the same location.

Implementing pagination in PHP with library Spatie Query Builder + React Tanstack Table

Tested with:

PHP 8.3
Laravel 11 with Spatie Laravel Query Builder
Next.js 15 with TanStack Table

How to Prevent Page Refresh When Swiping Down on Mobile

In many mobile browsers, a "pull down" gesture at the top of the page can trigger the "pull-to-refresh" functionality. While useful in some scenarios, this behavior can be undesirable in web applications that utilize touch elements or where the page should not be reloaded.

We can use touch events (touchstart and touchmove) to detect when the user tries to "pull down" from the top of the page. In this case, we can prevent the default refresh action, ensuring that normal scrolling continues to work.

To do this, I created the component below:

Implementação de rotina de verificação da conta de e-mail

Criar migração do model User adicionando o campo:

$table->timestamp('email_verified_at')->nullable();

Implementar a interface MustVerifyEmail no model User;

Custom password validation laravel 7:

	{
	if (!file_exists($filename) \|\| !is_readable($filename))
	return [];

	$row = 0;
	$fileContent = [];
	if (($handle = fopen($filename, "r")) !== FALSE) {

	<?php

	public function __toArray(): array
	{
	return call_user_func('get_object_vars', $this);
	}
