Let’s get started.


Laravel Installation

We will create laravel project using composer. So, please make sure your system should have composer installed. If not, may be this article will help you to Install composer in system.

Here is the command to create a laravel project-

$ composer create-project --prefer-dist laravel/laravel blog

To start the development server of Laravel –

$ php artisan serve

URL: http://127.0.0.1:8000

Assuming laravel already installed inside your system.


Create a Component File

Create a file with name message.blade.php inside /resources/views/components. You need to create a components folder as well inside it.

Open message.blade.php and write this complete code into it.

<div class="panel {{ $class }}">
    <div class="panel-heading">{{ $title }}</div>
    <div class="panel-body">{{ $slot }}</div>
</div>
  

Here, we have 3 placeholders as $class, $title and $slot.

When we will use this component then according to message type we will replace these values.


Create a Layout File

Create a my-template.blade.php blade layout file inside /resources/views folder.

Open my-template.blade.php and write this complete code into it.
