Laravel Survivor

This library solves the problem if you have a site open and the you're gone from your device for some time. In this case the CSRF token used on your forms expires, and you get an Exception., _(*1)

The purpose of this library is to keep the session from expiring, but also to keep the tokens up to date throughout your application., _(*2)

Installation (Laravel 5.2 is required)

Install via composer, _(*3)

composer require influendo/laravel-survivor, _(*4)
Add the script to your view. You can also add it to your footer.blade.php partial or your main layout file (by your own preference):, _(*5)

{!! survivor() !!}, _(*6)

Laravel 5.4 or older

If you're running Laravel 5.4 or older, you need to manually register the service provider. So just add the service provider to your config\app.php file:, _(*7)

Influendo\LaravelSurvivor\SurvivorServiceProvider::class,

Configuration

To configure the library you just need to publish the default vendor configuration:, _(*8)

php artisan vendor:publish --tag=survivor

You can change the interval in miliseconds, the path for ping route and the query selector for input elements which will be updated when a token expires., _(*9)

Funcionality

First of all the library pings a custom created endpoint in a predefined interval to keep your session up to date. When the CSRF token expires, the endpoint returns a new token, and the script then updates all the input fields named "_token" and a meta tag named "csrf-token"., _(*10)

If your using any 3rd party scripts, you can fetch the valid token at any time from the window.LaravelSurvivor.token object., _(*11)
