npm install log4js
Run the tests with
node tests.js. They use the awesome jspec - 3.1.3
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.
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
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.
