how to stringify a string to javascript backquote

Is there a way to safely stringify a string to a javascript backquote string?

example:

function stringToDoubleQuote(str: string) {
  return JSON.stringify(str)
}

function stringToBackQuote(str: string) {
  // ...
}

test:

const quotelist = `- 'singlequote'
- "doublequote"
- `backquote`
- template: ...${0}...${1}...`
console.log('(A)', stringToDoubleQuote(quotelist))
console.log('(B)', stringToBackQuote(quotelist))

expected output:

(A) "- 'singlequote'n- "doublequote"n- `backquote`n- template: ...${0}...${1}..."
(B) `- 'singlequote'
- "doublequote"
- `backquote`
- template: ...${0}...${1}...`

Use case

My goal is to create a module that transforms css files into js files, I want to keep the output file readable and not be a long line full of n, hence the use of backquotes.

for example, this css code:

body {
  color: fuchsia;
  background: khaki;
}
main{
  margin: 2em;
  padding: 1em;
}

must not be transformed into this:

const styleElement = document.createElement('style')
document.head.append(style)
styleElement.append( /* css */ "body {n  color: fuchsia;n  background: khaki;n}nmain{n  margin: 2em;n  padding: 1em;n}")

but this:

const styleElement = document.createElement('style')
document.head.append(style)
styleElement.append( /* css */ `body {
  color: fuchsia;
  background: khaki;
}
main{
  margin: 2em;
  padding: 1em;
}`)
