The correct namespace alias in the top of your class is:
use Spatie\YamlFrontMatter\YamlFrontMatter;
Or use it as a fully-qualified class name inline in your code:
\Spatie\YamlFrontMatter\YamlFrontMatter::parse($yaml);

Class "YamlFrontMatter" Not Found - Laravel, Docker, Composer
Recently, I've been following the "Laravel 8 From Scratch" Laracast, and chose to install Laravel using the Bash script installer method and running Laravel in a Docker container. I was happily following along until the instructor asked us to install YamlFrontMatter using Composer.
I opened the CLI for [project-name]_laravel.test_1, and ran the command: composer require spatie/yaml-front-matter. It seemed to install fine. So I returned to my code and tried to use the class in web.php as instructed, VSCode didn't complain, I then reloaded the webpage: 'Class "YamlFrontMatter" Not Found'.
So obviously, I think I need to import it with use, except, the instructor doesn't show that block of code, and I've tried every logical import I can think of ("use Vendor\Spatie\YamlFrontMatter" OR "use Spatie\YamlFrontMatter" OR "use YamlFrontMatter"), and I've also tried deleting the vendor folder & composer.lock file and reinstalling all the packages again, but to no avail. All produce the same error.
Can someone please help?

@tykus Thank you for the solution but I tried it both ways and it did not work for me perhaps it is something related to Laravel 9.

Thank you! I just ended up figuring this out myself by installing PHPStorm (the IDE used in the demo) and seeing what it imported when I used the YamlFrontMatter in the file.
Looking at the YamlFrontMatter.php file again, it's blindingly obvious now.
Many thanks either way!

For "independent" classes like yaml, i would suggest you install them via composer with terminal in your VScode or PHPStorm, this will root the install in your current project.

@inocrypt You most likely forgot to put the metadata in the first place.

For those who are using VSCode, and facing this issue. Even though the IDE screams that it can not recognize YamlFrontMatter, it works. Generally restarting the IDE worked for me.
