Output Nodes

Estimated reading time: 6 minutes

The output nodes receive the output from the input nodes. Their direction of communication, with respect to Flows, is outgoing. Each input node corresponds to an output node.

Debug Node

This is the most helpful code to debug messages on the fly. The messages are displayed in the Debug pane. The node can be configured to see the whole object or just msg.payload.
Debug Node
[
    {
        "id": "3fc09200.a531de",
        "type": "debug",

    }
]

MQTT Node

The user can publish any message to the server using this MQTT out node. It supports the basic authentication as well as quality of service (QoS) levels.

HTTP Node

This node sends the responses to the messages received from the HTTP input node. The body of the response message is defined by the msg.payload and it can have headers and a status code defined.
HTTP Node
[
    {
        "id": "ea431baa.b2d16",
        "type": "tab",

        "x": 580,
        "y": 200,
        "wires": []
    }
]


Web Socket Node

This node sends the message as msg.payload to the web server that is configured. If the connection to the particular client is defined for a session, it sends it to that client or alternatively, broadcasts the message to all clients.
Web Socket Node
[
    {
        "id": "ea431baa.b2d16",
        "type": "tab",
        "label": "Flow 1"
