# Typings

Current implementation relies of `static propTypes` declaration. The breakdown of this decision is as follows:

* **Only checked in development mode**, in production they are removed.<br>
* Do not provide type-hints to the developer. The **prop checking only occurs during the runtime**.

Typing implementation is subject to change. To circumvent the lack of type-hints we are in the progress of migration to TypeScript namespace declarations.
