Language and currency

The page's own words in the shopper's language, and prices in the currency the link asked for.

<script>
  window.nextConfig = {
    locale: 'fr-FR',
    translations: { fr: { 'page.title': 'Écouteurs Olympus', 'page.cta': 'Commander' } },
  };
</script>

<h1 data-next-i18n="page.title">Olympus earbuds</h1>
<p><span data-next-query="package.1.price"></span> <span data-next-query="campaign.currency"></span></p>
<a href="checkout.html" data-next-i18n="page.cta">Order now</a>

<a href="?currency=EUR">Prices in euros</a> · <a href="?lang=en">English</a>

Set window.nextConfig before the loader script. Texts are in ?lang=, else locale, else the campaign's language; a data-next-i18n key that neither the page's translations nor the address service has keeps the words written in the page. ?currency=EUR loads the campaign priced in euros, and prices are written in the page's language (49,00 € in fr-FR). Links to the site's other pages carry both parameters.

Events: campaign.loaded, with the campaign in the currency it was loaded in.
