可以使用yaml NPM包.

const YAML = require('yaml');

const jsonObject = {
    version: "1.0.0",
    dependencies: {
        yaml: "^1.10.0"
    },
    package: {
        exclude: [ ".idea/**", ".gitignore" ]
    }
}

const doc = new YAML.Document();
doc.contents = jsonObject;

console.log(doc.toString());

输出

version: 1.0.0
dependencies:
  yaml: ^1.10.0
package:
  exclude:
    - .idea/**
    - .gitignore
