In a quick post to the Laravel News site they mention another new feature coming in the v5.7 release of the framework: the addition of the dump server for debugging output.
At Laracon US 2018 Taylor Otwell announced that Laravel Dump Server would come packaged with Laravel in version 5.7! It will be a development dependency in laravel/laravel composer file.
Starting in Laravel 5.7 you’ll get this command out-of-the-box that allows you to dump data to the console or an HTML file instead of to the browser.
The post outlines what the "dump server" provides and provides an example of the command used to start it up. You can find out more about the dump server in this previous article.
