Uncaught EvalError: Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of script in the following Content Security Policy directive: "script-src 'self' blob: filesystem:".

I got the above error & solved it via https://stackoverflow.com/a/49100966/6141587

In short, added this to webpack.config.js:

devtool: 'cheap-module-source-map'

I think it'd be a great add to the boilerplate :)
