Add front matter to markdown in Node

Question

I am trying to generate .md files by Nodejs, and the file should contain the front matter.

This is what I am doing:

let {title,date,markdown_content}=document;
let fileContent = `
---
title: '${title}'
date: ${date}
---
${markdown_content}
`;

Now the title may contain special characters like " ' and etc(find more in this post).

Any nodejs library can be used out of box to do this job? Or I will have to replace the characters manually.
