Message backbone — Queue publish & browse

The built-in flowdrome.mq broker (zero config): publish an order event, check queue depth, browse without consuming — the decoupling backbone between producer and consumer flows (pair with the Thread Pool demo).

What’s inside

5 nodes — every type links to its full reference page.

Step	Node	Type
Order event	Inject	`input.inject`
Publish event	Message Queue	`utility.mq`
Queue depth	Message Queue	`utility.mq`
Browse (no consume)	Message Queue	`utility.mq`
Backbone view	Console	`utility.console`

Import it

Studio → Import — paste the JSON below (or the URL /docs/templates/message-backbone-queue-publish-browse.json).

Or ask the AI Copilot with the JSON pasted after the phrase:

import this workflow json into a new workflow named "Message backbone — Queue publish & browse"

Any credentials the nodes need are ${credential.…} references — add them once in Admin → Credentials and the template picks them up. Nothing secret ships in a template.
