Advanced tools
Package description
The 'yaml' npm package is a JavaScript library for parsing and serializing YAML, a human-friendly data serialization standard. It can be used to convert YAML to JSON and vice versa, and to work with YAML content programmatically in JavaScript.
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);
js-yaml is another popular YAML parser and serializer for JavaScript. It offers similar functionality to the 'yaml' package, including parsing and stringifying, and it also provides a safe loading option to prevent executing arbitrary code during parsing.
yamljs is a YAML parser and dumper written in JavaScript. It provides functionality similar to 'yaml' and 'js-yaml' but has a different API design and may have different performance characteristics.
