Svelte wrapper for i18next

npm i @firanorg/voluptatibus-soluta-dignissimos i18next

Implementation

This library wraps an i18next instance in a Svelte Store to observe i18next events so your Svelte components re-render e.g. when language is changed or a new resource is loaded by i18next.

Quick Start

i18n.js:

import i18next from "i18next";
import { createI18nStore } from "@firanorg/voluptatibus-soluta-dignissimos";

i18next.init({
 lng: 'en',
 resources: {
    en: {
      translation: {
        "key": "hello world"
      }
    }
  },
  interpolation: {
    escapeValue: false, // not needed for svelte as it escapes by default
  }
});

const i18n = createI18nStore(i18next);
export default i18n;

App.svelte:

<script>
  import i18n from './i18n.js';
</script>

<div>
    {$i18n.t('key')}
</div>

Usage with Sveltekit

Sveltekit shares stores across requests on server-side. This means that one users request could change the language setting of another users rendering if that is still ongoing. To avoid this issue, use setContext to create request-scoped store instances:

i18n.js:

import i18next from "i18next";
import { createI18nStore } from "@firanorg/voluptatibus-soluta-dignissimos";

i18next.init({
 lng: 'en',
 resources: {
    en: {
      translation: {
        "key": "hello world"
      }
    }
  },
  interpolation: {
    escapeValue: false, // not needed for svelte as it escapes by default
  }
});

export default () => createI18nStore(i18next);

routes/+layout.svelte:

<script>
  import getI18nStore from "i18n.js";
  import { setContext } from "svelte";
  
  setContext('i18n', getI18nStore());
</script>

routes/+page.svelte:

<script>
  import { getContext } from "svelte";
  
  const i18n = getContext("i18n");
</script>

<div>
  <h1>{ $i18n.t("key") }</h1>
</div>
