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<PaymentRequestEvent>(...) or constructor new PaymentRequestEvent(...)

let paymentRequestEvent;
let resolver;
let client;

// `self` is the global object in service worker
self.addEventListener("paymentrequest", async (e) => {
  if (paymentRequestEvent) {
    // If there's an ongoing payment transaction, reject it.
    resolver.reject();
  }
  // Preserve the event for future use
  paymentRequestEvent = e;

  // …
});
