Closing this and working on updating the build to use TSC with a new issue.

@azdanov Can you do a PR and add a contributors property to the package.json for yourself since you co-wrote this library.

Add this to webpack.config.js:

externals: {
  react: "commonjs react",
  "prop-types": "commonjs prop-types"
}
