## usage
|
||||
|
||||
Minimalist version:
|
||||
|
||||
var log4js = require('log4js');
|
||||
var logger = log4js.getLogger();
|
||||
logger.debug("Some debug messages");
|
||||
|
||||
```javascript
|
||||
var log4js = require('log4js');
|
||||
var logger = log4js.getLogger();
|
||||
logger.debug("Some debug messages");
|
||||
```
|
||||
By default, log4js outputs to stdout with the coloured layout (thanks to [masylum](http://github.com/masylum)), so for the above you would see:
|
||||
|
||||
[2010-01-17 11:43:37.987] [DEBUG] [default] - Some debug messages
|
||||
|
||||
See example.js for a full example, but here's a snippet (also in fromreadme.js):
|
||||
```javascript
|
||||
var log4js = require('log4js');
|
||||
//console log is loaded by default, so you won't normally need to do this
|
||||
//log4js.loadAppender('console');
|
||||
log4js.loadAppender('file');
|
||||
//log4js.addAppender(log4js.appenders.console());
|
||||
log4js.addAppender(log4js.appenders.file('logs/cheese.log'), 'cheese');
|
||||
```javascript
|
||||
var logger = log4js.getLogger('cheese');
|
||||
logger.setLevel('ERROR');
|
||||
|
||||
var log4js = require('log4js');
|
||||
//console log is loaded by default, so you won't normally need to do this
|
||||
//log4js.loadAppender('console');
|
||||
log4js.loadAppender('file');
|
||||
//log4js.addAppender(log4js.appenders.console());
|
||||
log4js.addAppender(log4js.appenders.file('logs/cheese.log'), 'cheese');
|
||||
|
||||
var logger = log4js.getLogger('cheese');
|
||||
logger.setLevel('ERROR');
|
||||
|
||||
logger.trace('Entering cheese testing');
|
||||
logger.debug('Got cheese.');
|
||||
logger.info('Cheese is Gouda.');
|
||||
logger.warn('Cheese is quite smelly.');
|
||||
logger.error('Cheese is too ripe!');
|
||||
logger.fatal('Cheese was breeding ground for listeria.');
|
||||
|
||||
logger.trace('Entering cheese testing');
|
||||
logger.debug('Got cheese.');
|
||||
logger.info('Cheese is Gouda.');
|
||||
logger.warn('Cheese is quite smelly.');
|
||||
logger.error('Cheese is too ripe!');
|
||||
logger.fatal('Cheese was breeding ground for listeria.');
|
||||
```
|

Output:

The first 5 lines of the code above could also be written as:

## configuration

|

@ -91,17 +91,20 @@ By default, the configuration file is checked for changes every 60 seconds, and
|
||||
|
||||
To turn off configuration file change checking, configure with:
|
||||
|
||||
var log4js = require('log4js');
|
||||
log4js.configure('my_log4js_configuration.json', {});
|

```javascript
|
||||
var log4js = require('log4js');
|
||||
log4js.configure('my_log4js_configuration.json', {});
|

```
|
||||
To specify a different period:
|
||||
|
||||
log4js.configure('file.json', { reloadSecs: 300 });
|
||||
|
||||
```javascript
|
||||
log4js.configure('file.json', { reloadSecs: 300 });
|
||||
```
|
||||
For FileAppender you can also pass the path to the log directory as an option where all your log files would be stored.
|
||||
|
||||
log4js.configure('my_log4js_configuration.json', { cwd: '/absolute/path/to/log/dir' });
|
||||
|
||||
```javascript
|
||||
log4js.configure('my_log4js_configuration.json', { cwd: '/absolute/path/to/log/dir' });
|
||||
```
|
||||
If you have already defined an absolute path for one of the FileAppenders in the configuration file, you could add a "absolute": true to the particular FileAppender to override the cwd option passed. Here is an example configuration file:
|
||||
|
||||
#### my_log4js_configuration.json ####
