Cloud function
A serverless compute unit that runs a single piece of code in response to an event. PURIST uses cloud functions (AWS Lambda, Google Cloud Functions) for custom logic that runs alongside n8n lightweight, scalable, and cost-effective.
Expert insight
A cloud function (AWS Lambda, Google Cloud Function) is the right tool when a workflow needs custom logic too heavy for a visual automation platform's code node, but it introduces its own deployment, versioning, and cold-start latency considerations that a no-code node doesn't have, worth the complexity only when the logic genuinely needs it.
In a real workflow
A small cloud function resizes uploaded images and returns the URL to the workflow.
Common mistakes
- Putting long-running jobs in functions with short timeouts.
- No logging or alerting on function errors.
