Parsing BCP 47 Language Tags

This feature allows you to parse a BCP 47 language tag into its components. For example, 'en-US' would be parsed into an object representing the language 'English' and the region 'United States'.

const bcp47 = require('bcp47');
const parsedTag = bcp47.parse('en-US');
console.log(parsedTag);

Validating BCP 47 Language Tags

This feature allows you to validate whether a given string is a valid BCP 47 language tag. For example, 'en-US' would return true, indicating it is a valid tag.

const bcp47 = require('bcp47');
const isValid = bcp47.validate('en-US');
console.log(isValid);

Stringifying BCP 47 Language Tags

This feature allows you to convert an object representing a BCP 47 language tag back into its string form. For example, an object with language 'en' and region 'US' would be converted back to 'en-US'.

const bcp47 = require('bcp47');
const tagObject = { language: 'en', region: 'US' };
const tagString = bcp47.stringify(tagObject);
console.log(tagString);
