Import types from DT

[hueniverse]

Until we have full and official types support, and to make migration back to the joi module name (without the @hapi/ namespace), I'm importing the types from https://github.com/DefinitelyTyped/DefinitelyTyped/tree/master/types/hapi__joi here.

They are going to be for v17.1 and will be lacking some features until v18 is released.

I am using TypeScript. How can I define the type of the ValidationResult now?
I used to use

typescriptfunction validateData(data: DataType): ValidationResult<DataType>{
  // ...
}
