Bielu.AspNetCore.AsyncApi.CloudEvents

Describes your AsyncAPI messages as CloudEvents 1.0 events, so the document says what actually goes over the wire: the id, source, specversion and type attributes every consumer relies on, named the way each protocol binding names them.

Installation

dotnet add package Bielu.AspNetCore.AsyncApi.CloudEvents

Usage

builder.Services.AddAsyncApi(options => options
    .AddServer("kafka", "broker:9092", "kafka")
    .AddCloudEvents(cloudEvents => cloudEvents
        .WithSource("/orders")                 // pinned with const
        .WithTypePrefix("com.example.orders.") // type = prefix + message name
        .ConfigureMessage("orderCancelled", message => message.Type = "com.example.orders.cancelled.v2")));
  • Binary mode (default): each message's headers gain the context attributes. With a Kafka server they are ce_id, ce_source, ce_specversion, ce_type, …; HTTP/WebSockets use ce-, AMQP cloudEvents:, and MQTT 5 user properties have no prefix. The prefix is chosen from the protocol of the servers each message's channels use. Existing headers are kept and combined with allOf.
  • Structured mode (UseMode(CloudEventsMode.Structured)): the payload becomes the application/cloudevents+json envelope, with the original payload as data.

Message examples gain the attributes too, and the output validates against the official AsyncAPI 2.6.0 and 3.1.0 schemas.

Bielu.AspNetCore.AsyncApi.Wolverine

Wolverine integration for Bielu.AspNetCore.AsyncApi. Builds AsyncAPI channels, operations and messages from Wolverine's own message routing (SignalR, Kafka and any other transport), so the document follows the routing configuration instead of repeating it in attributes.
