@i18nlite/svelte

A lightweight and simple i18n library for SvelteJS

Install

npm install --save @i18nlite/core @i18nlite/svelte

Usage

Configuration:

src/i18n.ts:

import { I18nStore } from '@i18nlite/core'
import { makeI18n } from '@i18nlite/svelte'

export type AvailableLanguages = 'en-us' | 'pt-br'

export const languages: AvailableLanguages[] = ['en-us', 'pt-br']

const store = new I18nStore(languages[0] /* <- Default language */)

export const { useLanguage, useTranslate } = makeI18n(store)

Using translations:

src/App.i18n.json:

{
  "en-us": {
    "hello": "Hello {0}!",
    "world": "world"
  },
  "pt-br": {
    "hello": "Olá {0}!",
    "world": "mundo"
  }
}

src/App.svelte:

<script lang="ts">
  import { useTranslate } from './i18n'
  import i18n from './App.i18n.json'

  const t = useTranslate(i18n)

</script>

<div>{$t('hello', $t('world'))}</div>

Reading and changing current language

src/ChangeLanguage.i18n.json

{
  "en-us": {

  },
  "pt-br": {
    "pt-br": "Português Brasileiro",
    "en-us": "Inglês EUA"
  }
}

    languages,
    useLanguage,
    useTranslate,
  } from './config'

  const t = useTranslate(i18n)
  const [lang, changeLanguage] = useLanguage()

  function handleSelect(e: Event) {
    const target = e.target as HTMLSelectElement
    changeLanguage(target.value as AvailableLanguages)
  }
</script>

<select value={$lang} on:input={handleSelect}>
  {#each languages as lang (lang)}
    <option value={lang}>
