Quick Start

Setup Providers

import { TwilightProvider } from '@salla.sa/twilight-theme-engine';
import { I18nProvider } from '@salla.sa/twilight-theme-engine/i18n';

function App() {
  return (
    <TwilightProvider storeIdentifier="my-store" defaultLocale="ar">
      <I18nProvider locale="ar" translations={translations}>
        {children}
      </I18nProvider>
    </TwilightProvider>
  );
}

Component Registry

import { registry, Component, defineComponent } from '@salla.sa/twilight-theme-engine';

// Register components
registry.register('header', Header);
registry.register('product.card', ProductCard);

// Override in custom theme
registry.override('header', CustomHeader);

// Use dynamically
<Component name="product.card" product={product} />;

Hook System

import { defineHooks } from '@salla.sa/twilight-theme-engine/hooks/HookRegistry';
import { HookSlot } from '@salla.sa/twilight-theme-engine/hooks/HookSlot';

// Define hooks
defineHooks({
  'body:start': () => <AnnouncementBar />,
  'product:form.end': ({ product }) => <TrustBadges />,
});

// Use in pages
<HookSlot name="product:form.end" context={{ product }} />;

Use Contexts

import { useStore } from '@salla.sa/twilight-theme-engine/hooks/useStore';
import { useTheme } from '@salla.sa/twilight-theme-engine/hooks/useTheme';
import { useTwilight } from '@salla.sa/twilight-theme-engine';

function MyComponent() {
  const store = useStore();
  const theme = useTheme();
  const { user, isRTL } = useTwilight();

  const setting = theme.settings.get('header_is_sticky', true);
}

Translations

import { useI18n } from '@salla.sa/twilight-theme-engine/i18n';

function MyComponent() {
  const { t } = useI18n();

  return (
    <div>
      <h1>{t('pages.cart.title')}</h1>
      <p>{t('pages.products.sold_times', { count: 5 })}</p>
    </div>
  );
}

Utilities

import { useMoney } from '@salla.sa/twilight-theme-engine/hooks/useMoney';
import { useAsset } from '@salla.sa/twilight-theme-engine/hooks/useAsset';

function ProductCard({ product, featured }) {
  const { formatMoney } = useMoney();
  const { asset, cdn } = useAsset();

  return (
    <div className={cn('card', featured && 'card--featured')}>
      <img src={cdn(product.image.url, 400)} />
      <p>{formatMoney(product.price)}</p>
    </div>
  );
}
