A flow is a collection of nodes wired together and appears as a tab in the workspace. Flows are the main way of organising nodes. A flow has a context variable associated with it which is available to all nodes in the flow. See Understanding node-red context variables Click to rate this post! [Total: 3 Average: 5]

Deploying Node-Red Flows
When you come to deploying a flow you have four (node-red v0.2)options as shown below: Although the choices appear obvious the effect of the options isn’t and can cause some confusion. Click to rate this post! [Total: 2 Average: 4.5]

To create flows you will need to open the editor by going to editor url. The editor url is the machine name or IP address followed by the port number. e.g 127.0.0.1:1880/ if you are running the browser on the same machines as node-red. localhost:1880/ – steve-laptop:1880/ when running node-red on a remote machine 192.168.1.154:1880/ I currently run node-red on a Raspberry Pi and use a second machine (windows 10) to create flows. Using The Node Red Editor (UI) When you open the node-red editor for the first time you should start with an empty workspace as shown in the earlier screen shot above. The default view is a three column layout with nodes on the left ,the flows work space in the middle and a third column on the right. The third column or output pane has 4 to 5 tabs – info, debug, config, context and dashboard ( if installed). Note: In versions 0.19 and above there are now 5 tabs and additional tabs may be present depending on the nodes that have been installed. The two new ones are the configuration tab and the context tab. Video Introduction to The Editor The Node-Red Workspace A workspace can

Node red makes it easy to save, share and move flows between computers using the export and import feature. Flows are exported as a JSON file and imported from a JSON file. You can export parts of a flow or the entire flow or even all flows. Click to rate this post! [Total: 2 Average: 3]
