Parsing YAML to JSON

This feature allows you to parse a string of YAML content and convert it into a JavaScript object.

const yaml = require('yaml');
const yamlText = 'key: value\nnumber: 123';
const jsonObject = yaml.parse(yamlText);
console.log(jsonObject);

Stringifying JSON to YAML

This feature enables you to take a JavaScript object and serialize it into a YAML formatted string.

const yaml = require('yaml');
const jsonObject = { key: 'value', number: 123 };
const yamlText = yaml.stringify(jsonObject);
console.log(yamlText);

Custom Tags

This feature allows you to define custom tags for specialized YAML types, enabling the parsing of YAML content with custom data structures.

const yaml = require('yaml');
const customType = { identify: value => value instanceof Set, tag: 'tag:yaml.org,2002:set', resolve: (doc, cst) => new Set(cst.strValue.split(', ')) };
yaml.defaultOptions.customTags = [customType];
const yamlText = '!!set a, b, c';
const data = yaml.parse(yamlText);
console.log(data);
