Console Logger (loggerNode)

Category: Outputs

Intended behavior

Logs the input value when the trigger signal is fired.

Inputs

ID	Label	Type	Unwired default
inTrigger	Log	trigger	undefined
value	Value	any	"log me"

Outputs

ID	Label	Type	Default
outTrigger	Out	trigger	undefined

Configuration defaults

{
  "logs": []
}

Observed frontend behavior

This calls the production passive computation with the declared input/config defaults. Cached state, trigger execution and project wiring are separate.

{
  "kind": "passive-default-probe",
  "outputs": {}
}

Observed backend behavior

Offline production passive computation with the same declared defaults; no device or model service is invoked.

{
  "kind": "passive-default-probe",
  "outputs": {}
}

Current frontend implementation

Extracted production branches; helper calls and project execution context are defined in the referenced modules.

src/lib/execution-helpers.ts:368

if (type === "loggerNode") {
    const valToLog = inputs.value;
    const logStr = `[${new Date().toLocaleTimeString()}] ${
      typeof valToLog === "object" ? JSON.stringify(valToLog) : valToLog
    }`;
    const logs = [...(config.logs ?? []), logStr];
    updatedConfig = { ...config, logs };
    // Mirror the node's own log line into the app terminal so Log nodes are
    // readable without opening each node's panel.
    logEvent("info", "exec", `Log node: ${logStr}`);
    nextTriggerPort = "outTrigger";
  }

Verification limits

• Default passive probe is an observation, not proof of all configurations, trigger behavior, or correctness. See ../NODE_RUNTIME_AUDIT.md and ../AUDIT_VALIDATION.md for test evidence.
• Trigger inputs schedule actions; passive evaluation alone does not execute those actions. Wire a trigger source and test the full chain.
