Switch Node

Routes by comparing one evaluated value against ordered cases.

Config shape (code-grounded)​

  • config.value_expression: expression used to compute value
  • config.cases: array of { value, output }
  • config.default_output: optional fallback (defaults to default)

Example usage snippet​

{
  "id": "n_switch",
  "type": "switch_node",
  "config": {
    "value_expression": "{{ $json['http_trigger'].request.method }}",
    "cases": [
      { "value": "GET", "output": "read" },
      { "value": "POST", "output": "write" }
    ],
    "default_output": "unsupported"
  }
}

Output behavior​

  • Returns matched_output equal to the first matching case output.
  • Uses string comparison (fmt.Sprint) internally.
  • Falls back to default_output when no case matches.

Common pitfalls​

  • Case mismatch due to whitespace or letter casing.
  • Missing default_output edge and dropping unexpected values.
  • Using switch for complex predicates better handled by condition_node.
