logger class based on rule-functions. uses the console, a file and trigger an event for more complex action.
npm install lgis a super simple logger class for nodeJS. It's part of the VisualWeb Framework (currently not public).
it will log to the console, a (mongoDB) database, a file.
just pass the configuration options when instantiating a new logger and there you go.
``
Logger = require('logger');
var log = new Logger(
{
log2console:true,
rules: {
minLogLevel: function(config, logTarget, content, sender, logLevel) {
if (logLevel < 2) return false;
return true;
}
}
},
function(loggerInstance) {
// if you chose log2database, you will need to wait for the
// callback to be able to actually log...
}
);
log.add('this is a message', 'cyan', 'byTest', 2);
`
Loglevels:
error (1):
`
myLogger.error('Test ERROR message.', 'red', 'examples');
warn (2):
`
myLogger.warn('Test WARN message.', 'yellow', 'examples');
info (3):
`
myLogger.info('Test INFO message.', 'green', 'examples');
debug (4):
`
myLogger.debug('Test DEBUG message.', 'blink', 'examples');
trace (5):
`
myLogger.trace('Test TRACE message.', 'white', 'examples');
