node-red-contrib-splitview

Display two Node-RED flows at once. Right-click any flow tab that is not currently open and choose Splitscreen → Split Below or Splitscreen → Split Right.

Each pane is a complete editor viewport with its own minimap, zoom controls, pan, selection and scroll state. Palette nodes can be dragged into either pane. Drag the divider to resize the panes, use its circular button to swap the flows, or use its small close button to return to the normal editor. The divider position is restored with the split layout.

The shared sidebar controls appear only on the outermost (right or bottom) pane; its buttons operate the main editor sidebar.

Requirements

• Node-RED 5.0 or newer
• Node.js 22.9 or newer

Development install

From your Node-RED user directory:

npm install "C:/Users/Interko/Desktop/Projects/Node Red/Modules/node-red-contrib-splitview/current"

Restart Node-RED and refresh the editor.

Notes

The secondary pane loads the same Node-RED editor in a same-origin embedded view. Both panes therefore use the same runtime and authentication session. Avoid editing the same node in both panes simultaneously.
