How to customize the node red editor

Hey @Steve-Mcl
Any suggestion for this ?

Use MQTT or http, or whatever inter-process comms you are most familiar with for communicating with the flows.
What data do you want to send to the editor?

Hello Colin,
When flow is deployed my end node has some processed json data, that data I want to send to My UI component.
After getting in my UI comonent which is outside of Iframe of node-red editor . I will process that json and send result back to editor, so it can be accessible in node.

You could use an http endpoint in your server (the one outside the frame) and send/receive data in your end node code by accessing that endpoint.
