Once you have a [Next app working locally](https://nextjs.org/docs/#setup), you may deploy it for public access.

1. Revise the `npm start` script to set the [web listener `$PORT`](https://devcenter.heroku.com/articles/dynos#local-environment-variables):

Merge this entry into **package.json**:

```json
{
"scripts": {
"dev": "next",
"build": "next build",
"start": "next start -p $PORT"
}
}
```

⭐️ *In March 2019, [Heroku began running `npm run build` automatically](https://devcenter.heroku.com/changelog-items/1573), so the old `heroku-postbuild` script entry is no longer required.*

1. Ensure the app is a git repo, ignoring local-only directories:
