Sticky attributes
Sticky attributes are similar to regular attributes except they will be copied to any message immediately or subsequently sent as a result of the original message being processed.
These can be sent by specifying a value for stickyAttributes
await bus.send(
new ChargeCreditCard(),
{
stickyAttributes: {
ip: '229.40.202.156',
attempt: 0,
automatic: true
}
}
)
Sticky attributes can be accessed using the stickyAttribtues of the second parameter of a handler.
import { MessageAttributes } from '@node-ts/bus-messages'
​
await Bus.configure()
.withHandler(
ChargeCreditCard,
async (_: ChargeCreditCard, { stickyAttributes }: MessageAttributes) => console.log(attributes)
)
.initialize()
