Before being shipped to npm, cosmos-keys is built for the Webpack target web (the default). Since there is no separate WebPack build for node, I would not expect the package to reliably run in Node.js at all. See https://webpack.js.org/concepts/targets/ and https://webpack.js.org/configuration/target/.
