Bielu.AspNetCore.AsyncApi.Avro

Describes your AsyncAPI message payloads as Apache Avro schemas, declared with schemaFormat: application/vnd.apache.avro;version=1.9.0, the way Kafka teams using a schema registry expect them. The Avro schema is converted from the JSON Schema the generator already produces, so it follows your .NET types without a second definition to keep in sync.

Installation

dotnet add package Bielu.AspNetCore.AsyncApi.Avro

Usage

builder.Services.AddAsyncApi(options => options
    .AddServer("kafka", "broker:9092", "kafka")
    .AddAvroPayloads(avro => avro
        .WithNamespace("com.example.orders")    // namespace of records and enums
        .ForMessages("orderPlaced")));           // optional: only these messages
JSON Schema Avro
object with properties record named after the schema
nullable / not required union with null (defaulting to null when not required)
array, dictionary array, map
string enum enum
integer (int32, otherwise) int, long
number (float, otherwise) float, double
uuid, date-time, date, time formats uuid, timestamp-millis, date, time-millis logical types
byte format (byte[]) bytes

The JSON Schema stays under components/schemas, and headers stay JSON Schema. The output validates against the official AsyncAPI 2.6.0 and 3.1.0 schemas, including their Avro schema.
