XLF Translator

XLF Translator takes an XLF file as an input (e.g. terms.xlf), goes through all the translation units, translates them to the target language (locale) and saves them to a target file (e.g.terms.de.xlf).

If the file already exists, XLF Translator compares the ids of the translation units, if something already exists in the target file, it won't be overwritten.

This way, manual editions are possible after the auto-translations. They are not going to be overwritten.

Installation

npm i @jsboost/xlf-translator --save-dev

Import

import import { XlfTranslator } from @jsboost/xlf-translator

Usage

Before you can start XlfTranslator, you need to define 3 things:

1. inputXlfFilePath - The path to the source XLF file, which is going to be the source of the translations
2. localeFiles - Definitions of the target locales, including their file paths.
3. translate - A translate function, so you can customize it and use the service which you wish (e.g. GoogleTranslate, Deepl, etc.)

translate has to implement the following API:

export function translate (
  sourceText: string,
  targetLocale: string,
  sourceLocale?: string
): Promise<string> {

Create a new file four your script and call it something like this:

translate-xlf.ts

import { XlfTranslator, LocaleFile } from './translator';
import { translate } from './translate.func';

// Preparing params
const i18nFolder = `app/src/i18n`;
const inputXlfFilePath = `${i18nFolder}/terms.xlf`;
const localeFiles: LocaleFile[] = [
  { locale: 'en-US', filePath: `${i18nFolder}/terms.en-US.xlf` },
  { locale: 'es-MX', filePath: `${i18nFolder}/terms.es-MX.xlf` },
  ...
];

// Usage
const translator = new XlfTranslator(
  inputXlfFilePath,
  localeFiles,
  translate
);
translator.start();

Execute it like this:

ts-node translate-xlf.ts

And watch the results:
