## Command line
|
|
|
|
Enable console logging with the `--logLevel` command line flag.
|
|
|
|
Hugo has four logging levels:
|
|
|
|
error
|
|
: Display error messages only.
|
|
|
|
```sh
|
|
hugo --logLevel error
|
|
```
|
|
|
|
warn
|
|
: Display warning and error messages.
|
|
|
|
```sh
|
|
hugo --logLevel warn
|
|
```
|
|
|
|
info
|
|
: Display information, warning, and error messages.
|
|
|
|
```sh
|
|
hugo --logLevel info
|
|
```
|
|
|
|
debug
|
|
: Display debug, information, warning, and error messages.
|
|
|
|
```sh
|
|
hugo --logLevel debug
|
|
```
|
|
|
|
{{% note %}}
|
|
If you do not specify a logging level with the `--logLevel` flag, warnings and errors are always displayed.
|
|
{{% /note %}}
|
|
|
|
## 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.
|
|
|
|
{{< list-pages-in-section path=/functions/fmt filter=functions_fmt_logging filterType=include >}}
|
|
|
|
## LiveReload
|
|
|
|
To log Hugo's LiveReload requests in your browser, add this query string to the URL when running Hugo's development server:
|
|
|
|
```text
|
|
debug=LR-verbose
|
|
```
|
|
|
|
For example:
|
|
|
|
```text
|
|
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.
