I am using [Cote](https://github.com/dashersw/cote) and monitor tool logged this to console.

```
import cote from 'cote';
cote.MonitoringTool(3000);
```

`
DeprecationWarning: Invalid 'main' field in '..../node_modules/@dashersw/node-discover/package.json' of 'discover'. Please either fix that or report it to the module author
