Anatomy of a Node
Every node shares a common structure:
- Inputs -- data flowing in from upstream nodes.
- Configuration -- parameters specific to the node (e.g. URL for HTTP Request, query for Database SQL).
- Outputs -- one or more output handles that connect to downstream nodes.
- Expressions -- dynamic values using
{{ $json.field }}syntax to reference upstream data.
