Switch

The switch block is used to conditionally run workflows based on evaluation of input value.

Default config

{
  "type": "switch",
  "valueGetter": "data",
  "cases": []
}

Supported properties

• valueGetter - JMESPath to evaluate against incoming data to get value for comparison

• cases (default = []) - an array of cases, each case contains:

  • value - the value that must match for this case to run

  • blocks - the workflow items that are run when this case matches

  • valueGetter (optional) - a JMESPath expression to evaluate which is used to compare and select the appropriate case. Only the specified case that matches the evaluated expression will be run. If a valueGetter expression is not provided then the input data is used as the value to match against.

  • default - object contains one key:

    • blocks - the array of workflow items to run if no cases match

Notes

The comparison made to select the branch is that it’s the first branch where value === matchValue - where value is the value defined in the branch, and matchValue is the result of valueGetter , and === is the JavaScript “strict equality”.

If you are looking to perform a test against a more variable value, you will need to use a more complex expression in the initial valueGetter.

(test && value) || (otherTest && someOtherValue)
