Output node feature definitions

This page defines the features and design conventions that each output node should adhere to. The page is currently under development and changes to its contents are possible.

Output nodes MUST:

• Produce a clearly and well defined behaviour that affects some externals outside Node-RED

Output nodes SHOULD:

• Report errors using node.warn() or node.error() if the external systems are in an unexpected state/behaviour
• Clean up their state upon close node.on("close", function() {}

Output nodes COULD:

• TBC
