Using variables with YAML in Node.js

Question

Is there any way to parse data to a .yaml file in node.js? I've been searching about this for hours and found nothing useful.

Let's say I have a string in a .yaml file:

message: Hello, ${user.fullName}, have a nice day.

As I've been reading, there's something called "placeholders" but it seems only available in spring framework.

This is what I found.

And in other places, they use a different syntax like {{user.fullName}}

So, is there any way to replace ${user.fullName} with an actual value in node.js? I don't know if I should manually handle this thing that they call "placeholder" myself with string.replace(). I checked the main YAML docs and there's nothing called "placeholder" or even "variable" in their entire docs!

But, similarly, I can achieve a similar result with pug.js using #{user.fullName} (with # instead) and then call something like: pug.renderFile('template.pug', {fullName: 'Timothy'}). Check pug.js docs for more details.

Thanks for your help!
