Laravel Blade Directives are syntactic sugar functions that hide the underlying complex and ugly code. This make code more readable and clear.

Blade includes lots of built-in directives. But, this tutorial will help you with laravel blade directives that you’ll often reach out during your time in laravel.

1. Check whether the user is a guest or not using blade directive

This helps to check if the user is a guest i.e., not an authenticated user. For this purpose we use:

@if(auth()->guest())
    // The user is not authenticated.
@endif

To make this even easier, the blade provides us with @guest a directive. This helps to write code in a much shorter way.

@guest
    // The user is not authenticated.
@endguest

2. Check if the user is authenticated or not using blade directive

To check this, we can use the code given below:

@if(auth()->user())
    // The user is authenticated.
@endif

The above code works fine but as a programmer, we should always look for easy and shorter ways to write code. For that purpose, laravel provides blade directive which is @auth.

@auth
    // The user is authenticated.
@endauth

To combine the two directives we can use else:

@guest
    // The user is not authenticated.
@else
    // The user is authenticated.
@endguest

3. Include first view if it exists else include second view

Most of the websites nowadays have multiple themes. This might require us to include a file if it exists else include another file. We can easily achieve this by using laravel:

@if(view()->exists('first-view-name'))
    @include('first-view-name')
@else
    @include('second-view-name')
@endif

We can write the above code in much easier and shorter way with blade.

@includeFirst(['first-view-name', 'second-view-name']);
