Add additional logic on POST /flows request

General
1

Hi,

I would like to intercept the POST /flows API request (at runtime) and add additional logic before its sending a respond to the editor.
After looking at the docs I wasn't able to find hooks or other options to active this behavior.

Currently the only way I was able to detect the request is by accessing the RED.server (NodeRed node http server) object like this:

RED.server.on("request", (req, res) => {  ... })

But I'm unable to make it wait for my logic to finish.

Any Ideas will be welcome.
Thanks.

I Found a way to intercept the setFlow action although very hacky

import RED from 'node-red';

...

const setFlowOrg: Function = (RED as any).runtime.flows.setFlows;
const flowThis: any = (RED as any).runtime.flows;

(RED as any).runtime.flows.setFlows = async (...data: any[]) => {
  console.log("before.setFlows");
  const res = await setFlowOrg.apply(flowThis, data);
  console.log("after.setFlows");
  return res; 
}
