How to set up proxy in Next.js?

Question

proxy

Guys, welcome) There was a question about proxying in next.js. The previous version of the app used Create React App . proxy could be configured in the package.json file by adding one line of code. Now we need to perform a similar task in Next.js . We use a custom server https://nextjs.org/docs/advanced-features/custom-server . How can I set up proxying if we use a custom server in Next.js? I haven't found a good solution to this problem on the net yet. Perhaps someone faced a similar problem? please share your experience. There are similar examples where you can peep something. Thanks in advance .
