You're right, if you just want to use this code trying to do it in a TypeScript project is a pain. You either need to make some changes so props and its children are properly typed for TypeScript, or change the imports so they're not typed. Working to make the props properly typed seems pointless since the code is already using prop-types to type them.

However, changing the imports isn't actually too hard. Just create Button.tsx with your Button.js code as in my original answer, and then replace the import React from "React" and import PropTypes from "prop-types" statements with the code below. You'll see this makes React and PropTypes of type 'any' if you hover over them, and means TypeScript won't try type-checking everything.
