git clone https://github.com/mars/heroku-nextjs-custom-server-express cd heroku-nextjs-custom-server-express

Deploy it to the cloud with Heroku:
⚠️ Requires installing Heroku CLI
heroku create git add . git commit -m 'Next.js app on Heroku' git push heroku master
Heroku auto-detects that this is a Node.js app, and then executes:
npm run build
NODE_ENV=production npm start.
👉 An example deployment of master is running at https://nextjs-server.herokuapp.com/.
Most of the times the default Next server will be enough but sometimes you want to run your own server to customize routes or other kind of the app behavior. Next provides a Custom server and routing so you can customize as much as you want.

The example shows a server that serves the component living in
pages/a.js when the route
/b is requested and
pages/b.js when the route
/a is accessed. This is obviously a non-standard routing strategy. You can see how this custom routing is being made inside
