Code
Execute arbitrary JavaScript inside an automation step. Use it when built-in connectors and Transform nodes are not expressive enough for a transformation or calculation.
Authentication
Auth type: None
How it works
The Code node runs in an isolated sandbox via the Collabase code-runner microservice. Write a function that receives the step’s inputs and returns an object — the returned keys become the node’s output variables.
// Example: calculate a due date 7 days from now
const dueDate = new Date(inputs.startDate);
dueDate.setDate(dueDate.getDate() + 7);
return {
dueDate: dueDate.toISOString(),
dueDateFormatted: dueDate.toLocaleDateString("de-CH")
};
Fields
| Field | Description |
|---|
| Code | JavaScript function body. inputs is available as a pre-bound object containing all mapped input variables. Return a plain object. |
| Input mappings | Variables from previous nodes mapped to inputs keys |
| Timeout | Maximum execution time in milliseconds (default: 5000) |
The Code node does not have access to Node.js built-ins like fs, http, or require. Network access is blocked inside the sandbox. For external HTTP calls, use the HTTP connector instead.
For complex multi-step transformations that need external libraries, use the Python node (AI Microservices) or the HTTP connector to call a dedicated function endpoint.
