Transliterate Cyrillic → Latin in every possible way

This is the TypeScript port of the Python iuliia package

NPM Version Build Status Code Coverage Code Quality

Transliteration means representing Cyrillic data (mainly names and geographic locations) with Latin letters. It is used for international passports, visas, green cards, driving licenses, mail and goods delivery etc.

Iuliia makes transliteration as easy as:

// Typescript, ES6
import * as iuliia from "iuliia";
iuliia.translate("Юлия Щеглова", iuliia.WIKIPEDIA);
'Yuliya Shcheglova'
// CommonJS
const iuliia = require("iuliia");
iuliia.translate("Юлия Щеглова", iuliia.WIKIPEDIA);
'Yuliya Shcheglova'

Why use Iuliia

  • 20 transliteration schemas (rule sets), including all main international and Russian standards.
  • Correctly implements not only the base mapping, but all the special rules for letter combinations and word endings.
  • Simple API and zero third-party dependencies.

For schema details and other information, see (in Russian).

Issues and limitations


npm install iuliia


ES2015 JavaScript:

import iuliia from "iuliia";

// list all supported schemas
for (let schemaName of iuliia.Schemas.names()) {

// transliterate using specified schema
let source = "Юлия Щеглова";
iuliia.translate(source, iuliia.ICAO_DOC_9303);
// "Iuliia Shcheglova"

// or pick schema by name
let schema = iuliia.Schemas.get("wikipedia");
iuliia.translate(source, schema);
// "Yuliya Shcheglova"

ES5 browser JavaScript:

<script src=""></script>
    var source = "Юлия Щеглова";
    var result = iuliia.translate(source, iuliia.WIKIPEDIA);
