# HrynCo.RabbitMq
|
|
|
|
RabbitMQ publisher and consumer base for HrynCo applications.
|
|
|
|
## Contents
|
|
|
|
- `RabbitMqSettings` — connection settings record (host, port, user, password, virtual host)
|
|
- `IRabbitMqPublisher` / `RabbitMqPublisher` — publishes JSON-serialized messages to a named queue
|
|
- `RabbitMqConsumerBase<TMessage, TMessageData>` — background service base with connection management, manual ACK/NACK, retry, permanent-validation rejection, and backward-compatible context-aware handling
|
|
- `RabbitMqMessageContext` — neutral AMQP delivery metadata (`MessageId`, type, correlation, routing, headers, and redelivery state)
|
|
- `IRabbitMqMessage<TMessageData>` — message contract interface
|
|
- `CorrelationContext` — correlation ID carrier
|
|
|
|
## Packaging
|
|
|
|
This package is intended for reuse through NuGet. The test project is excluded from packing.
|
|
|
|
## Consumer extension points
|
|
|
|
Existing consumers can keep overriding `HandleMessageAsync(message, cancellationToken)`.
|
|
Consumers that need AMQP metadata can instead override
|
|
`HandleMessageAsync(message, context, cancellationToken)`. The base class retains
|
|
ownership of acknowledgements and retries.
|
|
|
|
Override `TryValidateMessage(...)` for application-specific permanent validation.
|
|
Returning `false` nacks the delivery without requeue before retry processing begins.
|
|
Keep validation errors free of credentials and sensitive payload values.
