> Console.log wrapper for heroku-like logs

[![Build Status](https://travis-ci.org/entwicklerstube/heroku-log.svg?branch=master)](https://travis-ci.org/entwicklerstube/heroku-log)

### Install

**yarn**

```

yarn add heroku-log

```

**npm**

npm install heroku-log --save

  fatal

} from 'heroku-log'

```

### Example

```js

// # On Heroku

herokuLog.info('Server is starting')

// 2017-05-24T08:58:42.857401+00:00 app[web.1] level=info message="Server is starting"

error(new Error('I am an error '))

### Tricks

Sometimes you don't want those logs e.g. when testing things, in this case you can pass a env variable in the command line and the module is muted

```

$ HEROKU_LOG=disable mocha test.js

```

### Timestamps

If the environment is not production `heroku-log` will add a simple time-mark at the beginning of each log, in production it will be hidden since Heroku adds a time block by itself.
