Logging
Command line
Enable console logging with the --logLevel command line flag.
Hugo has four logging levels:
- error
- Display error messages only.
hugo --logLevel error
- warn
- Display warning and error messages.
hugo --logLevel warn
- info
- Display information, warning, and error messages.
hugo --logLevel info
- debug
- Display debug, information, warning, and error messages.
hugo --logLevel debug
Template functions
You can also use template functions to print warnings or errors to the console. These functions are typically used to report data validation errors, missing files, etc.
- fmt.Errorf
- Log an ERROR from a template.
- fmt.Erroridf
- Log a suppressible ERROR from a template.
- fmt.Warnf
- Log a WARNING from a template.
- fmt.Warnidf
- Log a suppressible WARNING from a template.
LiveReload
To log Hugo’s LiveReload requests in your browser, add this query string to the URL when running Hugo’s development server:
debug=LR-verbose
For example:
http://localhost:1313/?debug=LR-verbose
Then monitor the reload requests in your browser’s dev tools console. Make sure the dev tools “preserve log” option is enabled.
