Production deployment

Once you have a Next app working locally, you may deploy it for public access.

Add the heroku-postbuild hook to automatically build the Next app on each deployment:

Merge this entry into package.json:
```
{
  "scripts": {
    "heroku-postbuild": "next build"
  }
}
```
🌈 In February 2017, Next was fixed, so the Heroku build adapter is no longer required.

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

git init
(echo node_modules/ && echo .next/) >> .gitignore

Create the Heroku app:
```
heroku create $APP_NAME
```

🚀 Deploy:

git add .
git commit -m 'Next.js app on Heroku'
git push heroku master
