Usage

<!-- LanguageSelector.svelte -->
<script>
  import { locale, locales } from 'svelte-intl'

  const setLocale = e => locale.set(e.target.value)

<select value={$locale} on:change={setLocale}>
  {#each $locales as l}
    <option value={l}> {l} </option>
  {/each}
</select>

options

See format-message options \ Just call options.set({ }) :)

• Type: svelte.Readable<formatMessage.SetupOptions> (but update merges with current config)

Tries to match the window.navigator.language to the available dictionaries

• Params:
  • defaultLocale {string}: If no match is found, returns this
