Batched Catalog Updates ​

Problem ​

Implement batched catalog updates 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.

ts
i18n.batch(() => {
  i18n.add('en', { nav: { about: 'About' } });
  i18n.add('en', { nav: { contact: 'Contact' } });
  i18n.add('en', { nav: { help: 'Help' } });
});

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.
