Connectum API Reference / @connectum/events-amqp / toAmqpPattern

Function: toAmqpPattern()

toAmqpPattern(pattern): string

Defined in: packages/events-amqp/src/AmqpAdapter.ts:75

Convert an EventBus wildcard pattern to an AMQP routing key pattern.

EventBus uses complete dot-separated wildcard tokens. RabbitMQ's * matches one topic segment and # matches zero or more; translating terminal > to *.# preserves its one-or-more rule. The translation is meaningful on a topic exchange only. subscribe() also rejects a complete # segment on topic exchanges (RabbitMQ treats it as a wildcard while EventBus treats it as literal text) and a complete * or > on a direct exchange when topologyMode is "assert" (the binding would be a literal key that never matches); fanout and headers exchanges accept any pattern because their queue receives every message.

Parameters

pattern

string

EventBus wildcard pattern

Returns

string

AMQP routing key pattern

Throws

When a complete > segment is not terminal.
