Inline Task

"type": "INLINE"


Inline Task helps execute necessary logic at Workflow run-time, using an evaluator. There are two supported evaluators as of now:

value-paramUse a parameter directly as the value
javascriptEvaluate Javascript expressions and compute value

Use Cases

Consider a scenario, we have to run simple evaluations in Conductor server while creating Workers. Inline task can be used to run these evaluations using an evaluator engine.


"name": "inline_task_example",
"taskReferenceName": "inline_task_example",
"type": "INLINE",
"inputParameters": {
"value": "${workflow.input.value}",
"evaluatorType": "javascript",
"expression": "function e() { if ($.value == 1){return {\"result\": true}} else { return {\"result\": false}}} e();"

Following are the parameters in the above example :

  1. "evaluatorType" - Type of the evaluator. Supported evaluators: value-param, javascript which evaluates javascript expression.

  2. "expression" - Expression associated with the type of evaluator. For javascript evaluator, Javascript evaluation engine is used to evaluate expression defined as a string. Must return a value.

Besides expression, any of the properties in the input values is accessible as $.value for the expression to evaluate.

The task output can then be referenced in downstream tasks like: "${inline_test.output.result}"
