Simple Queue for Node-RED
JSON →A Node-RED custom node that provides a simple queue to limit the number of messages processed concurrently. Version 1.1.0 is the latest stable release; the project has low release cadence. It is a lightweight solution for throttling message flow in Node-RED without external dependencies, unlike full-fledged message brokers. The queue operates per node instance with configurable concurrency count. Proper handling of queue_msg_id on error is essential to avoid message loss.
