based on how the devices connect into and out of Node-RED. There are no inputs or outputs for this node. The flows creates all listed things on deployment
Output connects to multiple inputs Multiple node output Messages Shallow copy on send Synchronous send ID assigned to each message Asynchronous send Deep copy on send Instantiation Node-RED JSON transformed to JavaScript during build 1:1 map from JSON type to class (maybe not always optimal) ...
A block can have avalue inputat the right side. Or avalue outputat the left side. Or both: Astatementis created by connecting value inputs and value outputs together horizontally, to pass data from the outputs to the inputs: In this example the Node-Red input message is cloned, and th...
It is also possible to send multiple messages from a function node in sequence. To do this, you return an array of messages in the output message array. Listing 5.15 shows how to write a function that returns 10 new messages containing number payloads from 0 to 9. Line 1 creates a new...

A node red flow consists of a series of interconnected nodes.(wired nodes). All nodes must have an input and can have 0 or multiple outputs. Nodes exchange data between each other using themsgobject. Each node receives themessage objectfrom the previous node, and can then pass this message...
Processing Nodes (e.g. function) Figure 2.2 The main types of nodes: input, output and processing Input nodes allow you to input data into a Node-RED application or “flow”. They have at least one output endpoint represented by the small grey square only on their right side. You use ...
