The highlighted version marks the latest release.

Guest User Gates:

This feature is add-on feature from the latest version 5.7 which was released in September 2018. This feature is used to initiate the authorization process for specific users. In Laravea l 5.6, there was procedure where it used to return false for unauthenticated users. In Laravel 5.7, we can allow guests to go authorization checks by using the specific nullable type hint within the specified controller within the specified controller is given below:

Explanation:

By using a nullable type hint the $user variable will be null when a guest user is passed to the gate, and you can then make decisions about authorizing the action. If you allow nullable types and return true, then the guest will have authorization. If you don’t use a nullable type hint, guests will automatically get this beautiful 403 response for Laravel 5.7 which is displayed below:

The difference between 403 and 404 error is that 404 is displayed when user tries to access the unknown resource or URL and 403 error as mentioned in the snapshot above is displayed if unauthorized user accesses the website.

Artisan Commands:

Laravel 5.7 comes with new way of treating and testing new commands. It includes a new feature of testing artisan commands and the demonstration is mentioned below:

Explanation:

1. Here a new class named “ArtisanCommandTest” is created under test cases module.
2. It includes a basic function of testBasicTest which includes various functionalities of assertions.
3. The artisan command of expectsQuestion includes two attributes. One with question and other with an apiKeySecret. Here, the artisan validates the apiKeySecret and verifies the input sent my user.
4. The same scenario applies for question “Please select a version” where a user is expected to mention a specific version.

Pagination Customizations:

Laravel includes a feature of pagination which helps a user or a developer to include a pagination feature. Laravel paginator is integrated with the query builder and Eloquent ORM. The paginate method automatically takes care of setting the required limit and the defined offset. It accepts only one parameter to paginate i.e. the number of items to be displayed in one page.

Laravel 5.7 includes a new pagination method to customize the number of pages on each side of the paginator. The new method no longer needs a custom pagination view.

The custom pagination view code demonstration is mentioned below:

The new pagination customization as per Laravel standards is mentioned below:

onEachSide refers to the subdivision of each pagination records with 10 and subdivision of 5.

Dump Server:

Laravel dump server comes with the version of Laravel 5.7. The previous versions do not include any dump server. Dump server will be a development dependency in laravel/laravel composer file.

With release of version 5.7, you’ll get this command which includes a concept out-of-the-box which allows user to dump data to the console or an HTML file instead of to the browser. The command execution is mentioned below:

Explanation:

The command runs a server in the background which helps in collection of data which is sent from the application that sends the output through the console. When the command is not running in the foreground, the dump() function is expected to work by default.

Callable Actions:

Laravel 5.7 introduces a new feature called “callable action URL”. This feature is same like the one in Laravel 5.6 which accepts string in action method. The main purpose of the new syntax introduced Laravel 5.7 is to directly enable you access the controller.

The syntax used in Laravel 5.6 version:

The similar action called in Laravel 5.7 is mentioned below:

One benefit of the new callable array syntax format is the feature of ability to navigate to the controller directly if a developer uses a text editor or IDE that supports code navigation.
