Examples

SpawnDev.SpawnJS Mapping Note: The JavaScript examples below show the standard Web API usage. In SpawnDev.SpawnJS, the same API is available with C# conventions:

• Properties and methods use PascalCase (e.g., readyState becomes ReadyState)
• Events use ActionEvent with +=/-= (e.g., addEventListener("click", fn) becomes OnClick += handler)
• Async methods return Task<T> instead of Promise<T>
• Objects should be disposed with using statements
• Access via JS.Get<ContentIndexEvent>(...) or constructor new ContentIndexEvent(...)

self.addEventListener("contentdelete", (event) => {
  const deletion = caches
    .open("cache-name")
    .then((cache) =>
      Promise.all([
        cache.delete(`/icon/${event.id}`),
        cache.delete(`/content/${event.id}`),
      ]),
    );
  event.waitUntil(deletion);
});

self.oncontentdelete = (event) => {
  // …
};
