How to check if a string is included in a certain type
Say you have
type Category = "twitter" | "youtube" | "spotify"
then you need to check if a string is of type Category
what would the condition look like?

Hi @j0hannes . Since TS basically gets removed from your code when you compile, AFAIK there's no way to check just by using the type you defined. You will probably have to check manually (something like
["twitter", "youtube", "spotify"].includes(value)) or use a lib such as Zod.
