How to exclude `node_modules/@types/**/node_modules`?

Use peerDependencies to ensure you only have one version of a dependency.

i.e. If I am using typings for angular and angular-mocks, angular-mocks will have its own @types/angular

@types/angular  // => 1.5.8
@types/angular-mocks // => 1.5.8
@types/angular-mocks/node_modules/@types/angular // => *

To prevent two version of @types/angular from being installed, declare @types/angular as a peerDependency in your package.json file.
