keys with special characters are always surrounded by double quotes

Hey there!

I just found out about your package and it is just what I needed. Just bumped into a minor styling issue that I wanted to share here: keys that have special characters in them are always displayed surrounded by quotes. For example, in the playground, if you change the key message into my-message, then it will be formatted with double quotes even though quote keys is inactive. This was unexpected behaviour to me (although it may be intentional?).

Keep up the good work!

That behavior is intentional to ensure the output conforms to JavaScript syntax. The object literal key name must be quoted if the name is not a valid identifier. The key name my-message contains a dash, but dashes are not allowed in identifiers.

If the property name would not be a valid JavaScript identifier or number, it must be enclosed in quotes.

OK @dpilafian thank you for the explanation. That is a clear argument. However, can you help me understand why it is desirable for the pretty printed JSON to conform to the JavaScript syntax? Is that for copy-pasting the printed JSON directly into code?

Would you consider an option where all output is just printed nicely without double quotes (my users do not care about JavaScript, they just want to read the configuration)?
