Where do the types/* dependencies belong?

See original GitHub issue

I noticed that the dependencies for @types/pug are in dependencies but the @types/node are in the devDependencies - shouldn’t these both be in the same place? Which one is correct?

By the way, @types/* is not only useful for Typescript users. It powers the VS Code’s and Jetbrains autocompletion/quick doc/refactoring, so it’s another reason why the dependency types should match. I wrote a small post about it.

@types/* packages should have the same type as the corresponding implementation package. If foo is a peerDependency then @types/foo should be a peer dependency. If bar is a dependency then @types/bar should be a regular dependency. It helps ensuring that the declaration and implementation live at the same level in the dependency tree and are picked up properly.

@types/node is a special case because there’s no corresponding package.
