Why do you need to stringify a Boolean ?

But this results in a string instead of boolean 🤔 Weird...

Drive-by comment: I misinterpreted https://webpack.js.org/plugins/define-plugin/#usage as suggesting that JSON.stringify was the way to include that string's value as code, but (reading the rest of the rules) it turns out JSON.stringify is only necessary when the value is already a string (to preserve the quotation marks). Other values will be stringified automatically, and true and false have no trouble with that. Simplified in apollographql/react-apollo-error-template#57.
