API

Access to supported languages

The raw sets of supported languages, as returned by DeepL API, are made accessible:

const { source } = require("deepl-languages");

console.log(source);
// [{language: 'BG', name: 'Bulgarian'}, {…}, {…}, …]

// OR
const deepL = require("deepl-languages");

console.log(deepL.dataSource);
// [{language: 'BG', name: 'Bulgarian'}, {…}, {…}, …]

Supported types are: source & target.

Check if a language is supported

isLanguageSupported(code, type) returns whether a language is supported or not:

code must be a BCP 47 language tag, as per ISO 3166-1
type must be either source or target (defaults to source)

const { isLanguageSupported } = require("deepl-languages");

console.log(isLanguageSupported("en"));
// true

console.log(isLanguageSupported("en", "source"));
// true

console.log(isLanguageSupported("en-gb", "target"));
// true
