How is the yaml beautifier implemented? It is perfect and can't find the tool/source code

[buckleyGI]

I tried a few yaml beatifiers and am impressed with the result of the goteleport conversion
https://goteleport.com/resources/tools/yaml-beautifier/

Is there an open source tool used that I don't know or is it a custom made implementation?
If it is the 2nd can you open source it? 😃 🙏 It is the perfect implementation for me

Glad you like it!

The source is private, but it's just using the https://www.npmjs.com/package/yaml node package with the following config.

{
  indent: 2,
  lineWidth: 0,
  doubleQuotedAsJSON: true,
  sortMapEntries: false,
}

I'm new to node and have been banging my head for half a day now why I don't get the literal block scalars (|) that the online tool at teleport gives.
I'm using the config of above but had to put doubleQuotedAsJSON in comments (false) otherwise the yaml node package is making a flow scalar out of it. Can I ask you if you are sure this is the config the online tool uses? Thank you! Learning node along the way here.

@zmb3 Can you give me any quick insights?
