Assert Node

An assert node can be used to define a condition and then whether that condition is true or false, one can define two different paths in the flow. An assert node takes two variables and an operator.

Variables

Each variable can be of the following type -

• Select - Selects a part of the output from the previous node. For instance previous node is request node that outputs { "id": 10, "category" : [ {"id" : 10, "status" : "available"} ], .....} , then you can use id or category.0.id to assign value to the variable. The actual values will be calculated on the fly when the graph is run.

• String - Assigns a value of type string to the variable.

• Number - Assigns a value of type number to the variable.

• Boolean - Assigns a value of type boolean to the variable.

• Now - Assigns a value of type now() epoch timestamp to the variable. The value of now() is calculated on the fly during graph run.

• Variable - You can reference any other variable from the set of global variables defined in the workflow.

Operator

Currently we support isEqualTo, isNotEqualTo, isGreaterThan, isLessThan but feel free to contribute other types of operators.
