Presenting the svelte wrapper for i18next.
This library, based on i18next, wraps an i18next instance inside a svelte store and observes the i18next events like languageChanged, resource added, etc. to be able to render our svelte components.

Package:

svelte-i18next - npm

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 "svelte-i18next";

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

export const i18n = createI18nStore(i18next);

App.svelte:

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

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

The implementation looks like this:
The package creates a Svelte writable of i18next and listens to the events triggered by any updates on the i18next instance.
For example, if an application loads a new namespace for their translations, the svelte_i18next package will trigger the
i18next.on(‘loaded’, function(loaded) {}) event.
Check the i18next events here.

Usage:
i18n.js

import i18next from "i18next";
import { createI18nStore } from "svelte-i18next";

i18next.init({
   lng: 'en',
   resources: {
     en: {
       translation: {
         "key": "hello world"
       }
     }
   }
});

export const i18n = createI18nStore(i18next);

App.svelte

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

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

See a example usage here: Svelte example
You could also use namespaces as you would using i18next and the svelte wrapper will re-render the translations based on the namespace provided.

import { createI18nStore } from 'svelte-i18next'
const i18n = createI18nStore(i18n_instance) 
i18n.loadNamespaces(['example']) // this triggers the re-render and loads translations from the provided namespace.
<div>
    {$i18n.t(key)}
</div>

Into svelte? Dealing with localisation?
