Rask.WebPush

Server-side Web Push sender. Signs VAPID and encrypts (RFC 8291, aes128gcm) push messages, then POSTs them to a browser PushSubscription endpoint. It is the send half that pairs with Rask.Wasm's IWebPush client — but it is transport-neutral: usable from a Rask Server app or any ASP.NET backend behind a WASM PWA.

No external dependencies beyond Microsoft.Extensions.* — all crypto is in-box System.Security.Cryptography.

Install

dotnet add package Rask.WebPush

Use

builder.Services.AddRaskWebPush(o =>
{
    o.VapidKeys = VapidKeys.Generate();          // generate once, then load from config/secrets
    o.Subject   = "mailto:admin@example.com";    // a contact the push service can reach
});

// ... inject IWebPushSender, then given a PushSubscription the browser sent you:
var result = await sender.SendAsync(
    subscription,
    new WebPushMessage { Title = "Hello", Body = "from the server" },
    ct);

// Inspect the result to prune dead subscriptions:
if (result.ShouldDelete) await store.RemoveAsync(subscription);

Notes

  • Standards-based — VAPID (RFC 8292) auth + RFC 8291 aes128gcm payload encryption; interops with any standard browser Push service (FCM, Mozilla, WNS).
  • Zero external deps — ECDH, HKDF and AES-GCM come from System.Security.Cryptography.
  • Generate a VAPID key pair once with VapidKeys.Generate() and keep the private key server-side; hand the public key to the browser subscription.
  • SendAsync returns a WebPushResult whose ShouldDelete / ShouldRetry flags map the push service's response to the action to take on the subscription.
