# Heroku

1000 free dyno hours split across all your apps

```bash
npm install -g heroku
```

### Deploy

Just creates url on the sport and adds remote(heroku) to repo(if run in git root)

Pushing to heroku builds and deploys

```bash
heroku create
git push heroku master 
heroku open
```

* Use `git push heroku cdn:master` to push a branch

#### Procfile

Add a textfile to root to configure, usually not required

### Usage

`heroku open` `heroku local`

**Tail logs**

`heroku logs --tail`

## Platforms

### Node

`npm run start`

The command in a web process type must bind to the port number [specified in the `PORT` environment variable](https://devcenter.heroku.com/articles/dynos#local-environment-variables). If it does not, the dyno will not start.

## Advanced

#### [Env Variables](https://devcenter.heroku.com/articles/config-vars)

```bash
 heroku config:set NODE_CONFIG_DIR=./server/config
```

### [Custom Domain](https://devcenter.heroku.com/articles/custom-domains)

1. `heroku domains:add nibble.blog` & `` `heroku domains:add www.nibble.blog ``, do for **BOTH**
2. The command will return a DNS target like `adjacent-beyond-4gewdoomo52mqsps2xp87wns.herokudns.com`
3. Set a CNAME record to the returned DNS Target for www(or both @ and www on cloudlfare) or ALIAS for @
