Parcel: Prevent parcel from strippings comments on specific lines in source file?

❔ Question

How to prevent parcel from strippings comments from specific lines in source file?

🔦 Context

I am creating a website which contains a code editor. The code editor will have some code in it by default. I would rather not encode the code into a string (in order to pass it into the editor.session.setValue() function) using an online encoder. Instead, I would like to just write the code and use the .toString() in order to get a string representation of the code. However, parcel build will strip out the comments, which is problematic, because I need the comments.

💻 Code Sample

Ideal Code:

let afunc = () => {
   //Print hello world - this comment will not be removed 
    console.log("hello world")
}
editor.session.setValue(afunc.toString())

What actually happens in the above example is that the comment is removed.

Parcel supports customizing terser options, see possible options here https://github.com/fabiosantoscode/terser#output-options

An example to not remove comments:

.terserrc

{
  "output": {
    "comments": "put some regex here"
  }
}
