I18nano NPM | npm.io

i18nano

Internationalization for the react is done simply.

Lightweight translation module with functionality similar to react-i18next.

Features

Async translation loading
Fallback translations
Preloading translations
Mustache-like templates
Deep object property lookup
And other cool stuff

Usage

Let's create typical, unopinionated and simple component with the following structure:

import { TranslationProvider, Translation } from 'i18nano';
import { load } from './load';

const translations = {
  // dynamic import static json
  'en': () => import('translations/en.json'),
  // or with custom load function
  'ru': () => load('ru')
};

export const App = () => {
  return (
    <TranslationProvider translations={translations}>
      <header>
        <Translation path="header">
          Loading...
        </Translation>
      </header>
    </TranslationProvider>
  );
};

And that's all it takes! For other available provider options see definition.

Components

Translation - recommended way to use i18nano
TranslationRender - low level rendering component

Hooks

useTranslation - returns the function to extract the translation
useTranslationChange - returns the object with information and useful functions such as switch and preload languages

HOCs

withTranslation - injects the translation function
withTranslationChange - injects the information and useful functions

Switch

To switch between languages, let's create a component using the hook as follows:

import { useTranslationChange } from 'i18nano';

export const LanguageChange = () => {
  const translation = useTranslationChange();

  return (
    <select value={translation.lang} onChange={(event) => {
      translation.change(event.target.value);
    }}>
      {translation.all.map((lang) => (
        <option key={lang} value={lang}>
          {lang}
        </option>
      ))}
    </select>
  );
};

Concurrent features

If you use react 18 it is recommended to use transition. Then when you switch languages, the last downloaded translation will be displayed instead of the loader.

Split

You can use several TranslationProviders to split up translation files, for example:

import { TranslationProvider, Translation } from 'i18nano';

const translations = {
  header: {
    'en': () => import('translations/header/en.json')
  },
  main: {
    'en': () => import('translations/main/en.json')
  }
};

export const Header = () => {
  return (
    <TranslationProvider translations={translations.header}>
      <header>
        <Translation path="title" />
      </header>
    </TranslationProvider>
  );
};

export const Main = () => {
  return (
    <TranslationProvider translations={translations.main}>
      <h1>
        <Translation path="title" />
      </h1>
    </TranslationProvider>
  );
};
