Question

I\'m still at the beginning in learning scala in addition to java and i didn\'t get it how is one supposed to do DI there? can or should i use an existing DI library, should it

Answer 1

Previous posts covered the techniques. I wanted to add a link to Martin Odersky's May 2014 talk on the Scala language objectives. He identifies languages that "require" a DI container to inject dependencies as poorly implemented. I agree with this personally, but it is only an opinion. It does seem to indicate that including a DI dependency in your Scala project is non-idiomatic, but again this is opinion. Practically speaking, even with a language designed to inject dependencies natively, there is a certain amount of consistency gained by using a container. It is worth considering both points of view for your purposes.
