Rendering response from Laravel exception

In your Laravel controller or somewhere in your code you probably have a try/catch like this:

use App\Exceptions\FailedRequestException;

class ApiController
{
    public static sendRequest()
    {
        $api = new SomeApi();
        
        try {
            $api->sendRequest();

            return response()->json([
                'data' => $api->getData(),
            ]);
        } catch(FailedRequestException $e) {
            return response()->json([
                'error' => 'Failed to send API request',
            ]);
        }
    }
}

Using traits to boot and initialize Eloquent models

If you ever used Eloquent events, you are probably aware of special boot() static method in Eloquent models. This method allows you to hook into special events by running given functions.

Logging executed database queries in Laravel

Testing Laravel validation errors with PHPUnit's data providers

Accessing parent and child components in Vue.js

In Vue.js creating nested components and passing data between them is pretty straight forward thanks to property binding and event emitting. Take this as an example.

How to register your global functions in PHP using Composer

Composer simplifies class autoloading with different techniques and standards. Nowadays most common class autoloading standard is PSR-4:

"autoload": {
    "psr-4": {
        "App\\": "src/"
    }
}

What is Laravel Livewire? Here's the same app created with Laravel Livewire and pure Vue.js

If you ever created a full-stack application with reactive frontend and AJAX-based data exchange, you know the drill, you:

• create an endpoint which returns JSON on resources
• create specific event handler on the frontend which sends AJAX request to the backend to fetch resources
• create frontend component which renders resources or handles user input

Validating ZIP file content in Laravel

Vue.js v-model binding on custom components

When working with form elements, Vue’s v-model directive comes useful for 2-way data binding. But when you create your own custom form components and wrap input elements inside, it becomes hard to maintain the same 2-way binding with custom form component and parent component.
