Have You Ever Encountered CORS Error?

Hello Guys!
Most likely in some part of your programming adventure you have encountered Cross-Origin Resource Sharing Error. It wouldn't allow you to use resources from your backend inside UI and gave you a massive headache.
Today I will explain, what CORS is and how to fix this issue in Spring Boot application. For frontend I will be using Svelte Kit.
And as allways, go check my code on Github:

Hey, thanks for asking! Which approach are you using? Global one or per endpoint?
