Source Replacement

import { createI18n } from '@vielzeug/i18nit';

const i18n = createI18n({
  fallback: 'en',
  locale: 'en',
  catalogs: {
    en: {
      dashboard: { heading: 'Dashboard' },
    },
  },
});

i18n.subscribe((snapshot) => {
  renderApp(snapshot);
});

i18n.register('en', {
  dashboard: {
    heading: 'Workspace',
    subtitle: 'Everything in one place',
  },
});

Notes

• register() is the single runtime source mutation API.
• Subscribers receive the current snapshot directly.
