Laravel 5: HTML with variables from DB for Mailable class - laravel

Question

So I need to store my blade email templates in database.
And now I am having problem to use db content with view, because dynamic informations are not rendered.
Here is the code to elaborate a bit more problem which I am facing:
Mailable class:
namespace App\Mail;
use Illuminate\Bus\Queueable;
use Illuminate\Mail\Mailable;
use Illuminate\Queue\SerializesModels;
use Illuminate\Contracts\Queue\ShouldQueue;
use App\User;
class activateUser extends Mailable
{
public $html;
public $user;
use Queueable, SerializesModels;
/**
* Create a new message instance.
*
* #return void
*/
public function __construct(User $user)
{
//this actually is much longer text coming from the DB - basicly coopied blade email template into the db
$this->html = 'Hi {{ $user->first_name }},<br /><br /> Your profile on our site has been activated.<br /><br />';
$this->user = $user;
}
/**
* Build the message.
*
* #return $this
*/
public function build()
{
return $this->view('emails.activateUser')->subject('Your account is activated');
}
}
Then the view emails.activateUser.blade.php looks like this:
{{ $html }}
And Inside of my controller I am calling this:
Mail::to($user->email)->send(new activateUser($user));
Problem is that actual username of the user will not be printed in the email and {{ }} will stay as well in email content.
Any ideas how to solve this, since my email template content needs to come from DB

You can use the Blade template compiler to compile a string:
public function compileBladeString(string $template, $data = []): string
{
$bladeCompiler = app('blade.compiler');
ob_start() && extract($data, EXTR_SKIP);
eval('?>' . $bladeCompiler->compileString($template));
$compiled = ob_get_contents();
ob_end_clean();
return $compiled;
}
You can then simply invoke this method with a string containing your template from the database.
