Rask.Signaling

The WebRTC signaling relay that Rask's ISignaling client connects to — the channel two peers trade an offer, an answer and their ICE candidates over before they can reach each other directly.

It depends on nothing from Rask.Server, only ASP.NET routing and WebSockets, so any ASP.NET host can map it — including a static-file host serving a published WASM bundle.

builder.Services.AddRaskSignaling(o =>
{
    // The framework can't know who belongs in which room. This is where you say.
    o.AuthorizeRoom = ctx => ctx.Services
        .GetRequiredService<IConversations>()
        .IsMemberAsync(ctx.User, ctx.Room);
});

app.MapRaskSignaling();

The host must have WebSocket support in the pipeline: Rask.Server's UseRask() calls app.UseWebSockets() for you, but a static-file host serving a published WASM bundle does not — call it yourself before mapping. The relay says so explicitly rather than refusing clients with a bare 400.

What it guarantees

It is a relay between untrusted peers, so:

  • Peer ids are minted by the server, never taken from the client.
  • A message reaches only a peer in the sender's own room, checked at delivery.
  • Nothing is ever echoed back to its sender.
  • Payload size, message rate, room size and room count are capped.
  • Authentication is required by default — a relay anyone can join is a way to reach other people's browsers, so opening it should be a decision, not an accident.
  • A refused join says the same thing whether the room was full or you weren't allowed in, so a caller can't probe which rooms exist.

The payload is an opaque string. The relay never parses an SDP or an ICE candidate — only the two browsers need to understand it.

Limits

Rooms are held in memory, per process. Signaling is short-lived, so there is nothing worth persisting, but a multi-instance deployment needs sticky routing on the signaling path — two peers assigned to different instances never see each other.
