How to Redirect From Backend To FrontEnd after Authentication

Question

I Have My Backend (nodejs) running on another Port And My Frontend (React) Running On Another Port...So After After Sending Credentials To Backend And Authentication...How Can I Redirect To Front End ?

Answer 1

res.writeHead(302, {
    Location: 'http://front-end.com:8888/some/path'
});
res.end();

If you specify the full url you can redirect to another port using NodeJS.

Answer 2

You may use a web API (Express JS) in nodejs to build web api and frontend any plainJS or modren libaries that will send HTTP request to backend. It will help more.
