# Logging

Crow comes with a simple and easy to use logging system.

## Setting up logging level

You can set up the level at which crow displays logs by using the app's `loglevel(crow::LogLevel)` method.

The available log levels are as follows (please not that setting a level will also display all logs below this level):

- Debug
- Info
- Warning
- Error
- Critical

To set a logLevel, just use `app.loglevel(crow::LogLevel::Warning)`, This will not show any debug or info logs. It will however still show error and critical logs.

Please note that setting the Macro `CROW_ENABLE_DEBUG` during compilation will also set the log level to `Debug`.

## Writing a log

Writing a log is as simple as `CROW_LOG_<LOG LEVEL> << "Hello";` (replace<LOG LEVEL> with the actual level in all caps, so you have `CROW_LOG_WARNING`).
