Kindly have a look on official changes in Laravel 5.4

Request Sanitization Middleware

There are two new middleware added in the default middleware stack in Laravel 5.4 :

TrimStrings Middleware will automatically trim/remove all white spaces comes with request data that means when you add extra spaces in your form field then it remove those white spaces automatically.

Here is example where you will see if you remove TrimStrings Middleware then it will return you response with extra white spaces and if you add TrimStrings Middleware then it remove extra white spaces from request data.

Without TrimStrings Middleware :

dd(request('title'));
// 'Expertphp.in '

With TrimStrings Middleware :

dd(request('title'));
// 'Expertphp.in'

ConvertEmptyStringsToNull Middleware will automatically convert all empty string to null value that means any field of form is empty or embeded with empty string then it convert back to null value.

Here is simple example for ConvertEmptyStringsToNull Middleware.

Let's assume i have a text input field that take title of project :

If i do not use ConvertEmptyStringsToNull Middleware and i left text field blank then response will be :


dd(request('title'));
// ''

If i use ConvertEmptyStringsToNull Middleware then this will now return null :


dd(request('title'));
// null

Blade Components and Slots

In Laravel 5.4, there is new features added with Blade template called @component directive.

Blade Components and Slots features are similar to sections and layouts.The features are desgined to provide you more flexibility in your blade templates.

You can use this features for those components that will be reusable throughout your application.

Example :

Let's have a example for showing an alert message :

<!-- /resources/views/message.blade.php -->
<div class="alert">
    {{ $slot }}
</div>

<!-- /resources/views/message.blade.php -->

<div class="alert">
    {{ $slot }}
</div>

Now you can inject it into your template like this :

@component('message')
    Your message 
@endcomponent

@component('message')
    Your message 
@endcomponent
