There is an application developed in spring and angularjs, the problem is that they want to make an app in nodejs and be able to embed it within the java application, I mean
Something like pressing a button, and look at your node app, suppose you add a calculator, a form that occurs to me with an iframe, I have the app node running on a server and calling iframe with that route when the button is pressed, however other forms are there? , and which ones would be the most recommendable, thanks.
PS: There is no possibility to change the spring app, nor the node app.
