Locale Switcher

Problem

Implement locale switcher in a production-friendly way with @vielzeug/i18nit while keeping setup and cleanup explicit.

Runnable Example

The snippet below is copy-paste runnable in a TypeScript project with @vielzeug/i18nit installed.

async function switchLocale(locale: string) {
  await i18n.switchLocale(locale);
  render();
}

for (const locale of i18n.locales) {
  console.log(locale);
}

Expected Output

• The example runs without type errors in a standard TypeScript setup.
• The main flow produces the behavior described in the recipe title.

Common Pitfalls

• Forgetting cleanup/dispose calls can leak listeners or stale state.
• Skipping explicit typing can hide integration issues until runtime.
• Not handling error branches makes examples harder to adapt safely.
