# Logging
You can use the logging class to output to a file.
use ```$log->info(The Message');```1
Logging levels are:
```
'DEBUG' => 0,
'INFO' => 1,
'WARNING' => 2,
'ERROR' => 3,
];
```
It's recommended that production is set to ERROR.
You set the log level in /App/config.php under 'loglevel' => 'ERROR'
If you are using CORXN a health check is run every 30 seconds which would fill the log file with info.

# Twig
## Overrides
You can override twig templates by creating the same file in the templates directory.
## Calling View
There is a $data that the system uses to store arrays for twig you can save to this array:
```
$data['newinfo'] = 'stuff';
view('templatename');
```
and that will automotically go to twig.
or you can create a new array and pass it in:
```
$anotherArr['newinfo'] = 'stuff';
view('templatename',$anotherArr);
```
