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

The key pair and the contact come from the Rask:WebPush configuration section. Generate the pair once with VapidKeys.Generate() and keep it in user secrets or the environment, never in source:

dotnet user-secrets set "Rask:WebPush:VapidKeys:PublicKey"  "<public>"
dotnet user-secrets set "Rask:WebPush:VapidKeys:PrivateKey" "<private>"

// appsettings.json
{
  "Rask": {
    "WebPush": {
      "Subject": "mailto:admin@example.com"    // a contact the push service can reach
    }
  }
}

builder.Services.AddRaskWebPush();   // reads Rask:WebPush; a callback here would run after it and win

// ... inject IWebPush, 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.

Rask

The one reference a Rask application needs, server or browser. On a server target (net10.0 or net11.0) it brings the ASP.NET host plus every battery — database (SQLite, PostgreSQL or SQL Server, picked by Rask:Database:Provider), mediator, background jobs, transactional email, cache, file storage, outbox, operator dashboard, durable logs, Web Push, and SQLite snapshots and continuous backup — with RaskApp.Create(args) as the entry point. On a browser target it brings the WebAssembly host, the source-generated mediator, the query cache and remote dispatch. Everything referenced is wired and on; app.Configure(c => c.Jobs.Off()) is how an app does without one. Reference Rask.Server for a lean host with no database.
