How to capitalize first letter in Laravel Blade

Use PHP's native ucfirst function:

{{ ucfirst(trans('messages.welcome')) }}

Use Laravel helper Str::title()

{{ Str::title('messages.welcome') }}

Add a blade directive to the app/Providers/AppServiceProvider's boot() function:

public function boot() {

    Blade::directive('lang_u', function ($s) {
        return "<?php echo ucfirst(trans($s)); ?>";
    });

}

This way you can use the following in your blade files:

@lang_u('messages.welcome')

which outputs: Welcome

You're @lang_u('messages.welcome') :)
