log4js-node

This is a conversion of the log4js framework to work with node. I've mainly stripped out the browser-specific code and tidied up some of the javascript.

installation

npm install log4js

tests

Run the tests with node tests.js. They use the awesome jspec - 3.1.3

usage

See example.js:

var log4js = require('log4js');
log4js.addAppender(log4js.consoleAppender());
log4js.addAppender(log4js.fileAppender('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.');

Output [2010-01-17 11:43:37.987] [ERROR] cheese - Cheese is too ripe! [2010-01-17 11:43:37.990] [FATAL] cheese - Cheese was breeding ground for listeria.

configuration

You can either configure the appenders and log levels manually (as above), or provide a configuration file (log4js.configure('path/to/file.json')). An example file can be found in spec/fixtures/log4js.json

todo

I need to make a RollingFileAppender, which will do log rotation.

patternLayout has no tests. This is mainly because I haven't found a use for it yet, and am not entirely sure what it was supposed to do. It is more-or-less intact from the original log4js.
