When i try to use library i end up with following error message :

./node_modules/rn-persian-date-picker/PDP.js 9:5
Module parse failed: Unexpected token (9:5)
You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders
| import { primaryFontFamily, smallFont } from "./modules";
| 
> type Props = {
|   type: "Jalali" | "Gregorian",
|   pickerConfirmBtnText: string,

apparently you are using typescript inside your module but the extension is .js could you please explain what is the issue?
