#winston-slackbotuser

[Winston](http://github.com/winstonjs/winston) transport to log as a [Slack bot user](https://api.slack.com/bot-users).

## Installation
`npm install winston-slackbotuser`

Adds a [new bot](https://my.slack.com/services/new/bot) to your Slack team and write down the API Token.

Adds `slackbotuser` transport to winston with API token and channel set. You can either add the transport to the default winston logger.
```js
winston.add(require('winston-slackbotuser'), {
    token: 'xoxb-1234567890-ABCDEFGHIJKLMNOPQRSTUVWX',
    channel: '#general'
});
```

Or with a new logger instance.
```js
require('winston-slackbotuser');

new (winston.Logger)({
    transports: [
        new (winston.transports.SlackBotUser)({
            token: 'xoxb-1234567890-ABCDEFGHIJKLMNOPQRSTUVWX',
            channel: '#general'
        }
    ]
});
```

By default, `slackbotuser` log level is set to `info`. If you want to log `debug` messages, set the `level` option to `debug`.
