I want to make a website using Next.js but I want to use WordPress for marketing pages. Let's say I want to use WordPress for a path example.com/sales and Next.js for others. I thought it could be done with load balancing but I'm new to this topic and not sure what I should do. How do I do that?
I think what you are looking for is called incremental adoption. Basically if a certain path is not part of your nextjs app, the traffic falls back to the specified url.
