Typescript traducciones en un enum, y no más strings weando

unnecesary

Lo uso con expo/reactnative, pero sirve para cualquier proyecto con typescript
Para agregar las traducciones, agregar al:
enum Words {
Después los archivos de traducciones ingles y español llorarán

// I18nService.ts

import * as Localization from 'expo-localization';
import { I18n } from 'i18n-js';
import { ITranslationLanguage } from '../interfaces/ITranslationLanguage';
import EnglishTranslation from '../translations/EnglishTranslation';
import SpanishTranslation from '../translations/SpanishTranslation';


class I18nService extends I18n
{
  static #_instance?: I18nService;
  constructor() {
    const translations: ITranslationLanguage = {
      en: EnglishTranslation,
      es: SpanishTranslation,
    };
    super(translations);
    this.locale = Localization.locale;
    this.enableFallback = true;
    this.locale = 'es';
  }

  public static getInstance(): I18nService {
    if (!I18nService.#_instance) {
      I18nService.#_instance = new I18nService();
    }

    return I18nService.#_instance;
  }
}

enum Words {
  user_name,
  user_lastname,
  get_actions,
  save,
}

const WordsHandler = {
  get: function (target: any, prop: string, receiver: any) {
    return I18nService.getInstance().t(prop);
  },
}
const Tr = new Proxy(Words, WordsHandler);

// gracias https://stackoverflow.com/questions/39701524/does-typescript-allow-an-enum-to-be-assigned-to-an-interfaces-object-key
type EnumKeys = keyof typeof Words;
type EnumKeyFields = {[key in EnumKeys]:string};

interface IWords extends EnumKeyFields{}

export {Tr, Words, IWords};


// archivos de traducciones por ejemplo EnglishTranslation.ts
import { IWords } from "../lib/I18nService";
const EnglishTranslation: IWords = {
    user_name: 'name',
    user_lastname: 'lastname',
    get_actions: 'Get Actions',
    save: 'save'
}

export default EnglishTranslation;

// en español SpanishTranslation.ts
import { IWords } from "../lib/I18nService";


const SpanishTranslation: IWords = {
    user_name: 'nombre',
    user_lastname: 'apellido',
    get_actions: 'Obtener acciones',
    save: 'guardar',
}

export default SpanishTranslation;

// Se usa:
import { Tr } from '../lib/Tr';
<Button
        title={Tr.save}
        color="#f194ff"
        onPress={saveNewAction}
      />
