Typescript type alias for enum

You should use import keyword instead of type:

import PropType = Somatic.PropType;

More info on import alias declarations here.

** This syntax won't work if you're using babel-plugin-transform-typescript because this is typescript only form of import. Generally using namespaces is not recommended.

In typescript, an enum is both a type and a map. You should alias the type and the map separately:

type PropTypeEnum = Somatic.PropType;
const PropType = Somatic.PropType;
