You can use `NEXT_PUBLIC_BACK_HOST=localhost:4000 npm run dev` to run the frontend and `PORT=4000 node dist/index.js` to run the backend after building it with `npm run build`. You could also just run `NEXT_PUBLIC_BACK_HOST='https://server.exozy.me' npm run dev` if you are only developing the frontend and connect to the public backend server.
## Production deployment
Edit the environmental variables in `./env` and use the script `./run`.
