As of Flow 0.3.0, it's now possible to import types from another module. So, for example, if you're only importing a class for purposes of referencing it in a type annotation, you can now use the new import type syntax to do this.

Also I won't speak about missing features in Flow since the purpose is as stated to improve TypeScript. Finally this topi
Flow, a new static type checker for JavaScript
Today we’re excited to release an early version of Flow, a new open-source static type checker for JavaScript. Flow adds static typing to JavaScript to improve developer productivity and code quality. In particular, static typing offers benefits like early error checking, which helps you avoid certain kinds of runtime failures, and code intelligence, which aids code maintenance, navigation, transf
