Need to Compile to ES5 before publishing to NPM

[ghost]

if you use create-react-app tool for your react app and you try to build your app for production by "npm run build" it will fail to minify the code in this file ./node_modules/mem/index.js

please look on this link for further information

This module mainly targets Node.js, not the browser. It's up to you to transpile it with Babel if you want to use it in the browser. You can find a more detailed explanation here: sindresorhus/ama#446

If you use Webpack, check out babel-engine-plugin, which transpiles only the dependencies that needs to be transpiled.
