import { RabbitMqTransport, RabbitMqTransportConfiguration } from '@node-ts/bus-rabbitmq'
const rabbitConfiguration: RabbitMqTransportConfiguration = {
queueName: 'accounts-application-queue',
connectionString: 'amqp://guest:guest@localhost',
maxRetries: 5
}
const rabbitMqTransport = new RabbitMqTransport(rabbitConfiguration)
// Configure Bus to use RabbitMQ as a transport
const run = async () => {
await Bus
.configure()
.withTransport(rabbitMqTransport)
.initialize()
}
run.catch(console.error)
