Scala type keyword: how best to use it across multiple classes

Question

Coming back to Scala after a spell writing Haskell, I\'ve started using the type keyword to make my class definitions a bit more readable, eg:

type RestfulParams

Youn can use a package object and put the type declaration in there. When you import that package the type definition will be available.

An example :

//package myType
package object myType {type mine = List[String]}

Notice that the package object has the same name as the package in order to be usable without a object prefix i.e myType.mine If you name it with a different name for example :

//package myType
package object mainType {type mine = List[String]}

it can be accessed with mainType.mine when you import "package"
