Implementation based off of camunda-external-task-client-js.
| Name | Type | Default | Description |
|---|---|---|---|
| CAMUNDA_REST_URL | string |
URL of Camunda REST API, i.e. http://localhost:8080/engine-rest or http://camunda:8080/engine-rest if inside of the docker-compose network. |
|
| WORKFLOW_SERVICE_BASE_URL | string |
Base URL for workflow-service. This will be moved to the handler configuration. | |
| TASK_FAILURE_RETRY_COUNT | number |
1 | Number of retries to perform if the task fails. Default is 1. |
| TASK_FAILURE_RETRY_TIMEOUT | number |
1000 | Number of milliseconds to wait between retries. Default is 1000. |
To run the examples packaged with the project, run
docker-compose up --buildYou will eventually see output similar to this:

The examples log the task and task.variables.getAll() objects. To match the outputs to the BPMN, see below.
activityId - corresponds to the task ID set in Camunda modeler, or to the id attribute of the following BPMN XML.
<bpmn:serviceTask id="rejectLoanRequest" name="Reject loan request" camunda:type="external" camunda:topic="requestRejecter">
<bpmn:incoming>SequenceFlow_0vpum3q</bpmn:incoming>
<bpmn:outgoing>SequenceFlow_1p8qb0a</bpmn:outgoing>
</bpmn:serviceTask>
