Is there any dynamic way of changing the proxy target in React JS (or any other Front-end JS), without restarting the application?

Is there any dynamic way of changing the proxy target in React JS, without restarting the application?

I have multiple node JS servers in the local intranet (which Uses Private IPs, with No concept of deploying using public IP). And I have one GUI using React JS, which will handle/manage multiple node JS servers.

Using one proxy settings configuration in package.json serves only one NodeJS server, If I update package.json with the next target in proxy, I need to restart the app again.

Is there any way to handle this?

Please help to resolve or overcome this issue

Thanks, With Regards Sujeet Kalaskar
