Employing the next function in conjunction with an Express server during development

I currently have an express server handling my back-end operations. I am now in the process of transitioning my front-end to nextJS and would like to set up a proxy for my nextJS requests to access the port that my back-end is running on. Is it possible to achieve this?

One major challenge I am facing is the inability to utilize authentication cookies because the back-end handles the OAuth flow on port 5000 while the front end is hosted on port 3000. My prefered solution would be to route everything through port 3000, with nextJS quietly redirecting in the background to enable me to use session cookies normally.

Answer №1

There are various methods you can utilize to implement this:

  1. The front end server can act as a proxy for the api backend using.

    For instance http://localhost:3000/api/ will be forwarded to the back-end service. https://github.com/chimurai/http-proxy-middleware

  2. Implementing a reverse proxy in front of both services, like nginx.

    This approach comes with multiple advantages:

    1. Serving static assets from nginx (which it excels at) can reduce requests from your front end service.
    2. Caching requests without modifications to your services.
    3. Load balancing multiple instances of your api / front node services -advanced.
