ServerSentEventsModule

The ServerSentEventsModule is used to set up Server-Sent Events. This module sets up a middleware.

Definition

/// <summary>
/// Use Server Sent Events Module
/// It setups a Middleware
/// </summary>
public static SimpleWServer UseServerSentEventsModule(this SimpleWServer server, Action<ServerSentEventsOptions>? configure = null)

Example

See examples of use.

Authorization

Use ServerSentEventsOptions.Authorize to reject an SSE connection before the handshake:

server.UseServerSentEventsModule(options => {
    options.Prefix = "/events";
    options.Authorize = session => session.Principal.IsAuthenticated;
});

When the callback returns false, the module responds with 403 Forbidden and does not switch the HTTP session to SSE streaming.
