node-red-contrib-camunda v2.0.0
node-red-contrib-camunda
This module leverages the camunda-external-task-client-js client library to bring Camunda awesomeness to Node-RED! It also interact with the Camunda REST API and supports Basic Auth.
Nodes
worker / complete
Creates an external task worker and subscribes to specific topic. The worker node outputs a Node-RED message for each newly received external task task.
When a Node-RED message is received at the complete nodes's input, that external task gets completed in Camunda (with either success, failure or error).
Please note: These nodes only work in combination. Make sure, the complete object from the worker node output payload gets injected into the input of the complete node.
create process instance
A new process instance gets started in Camunda, when a Node-RED message is received at the input.
Once the process instance has been created, the output sends a Node-RED message containing some meta-info, i.e. the processInstanceId.
correlate message
This node correlate a message to Camunda, when a Node-RED message is received at the input.
deploy
Inject a bpmn definition definition string to the input of this node to deploy it to Camunda.
You can use the 'file in' node from Node-RED to read a bpmn file from disk, or get the process definition from anywhere you want.
variables helper
To help you build payloads to create process instances or correlate messages, a variable helper is provided.
