Using NPM package

We can use https://github.com/eemeli/yaml NPM package.

File convert.js

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());
