#Ledger Ledger is an event based NodeJS module used for logging events to stdout, files or MongoDB.

By default Ledger can overwrite console.log, console.info, console.warn and console.error to allow all output to be either colorized or outputted to a file or a MongoDB server.

##Installation:

npm install ledger

##Usage:

//this will output to stdout/stderr
//ledger.log and MongoDB listening at 127.0.0.1
var ledger = (require('ledger')({
    logFile: 'ledger.log',
    logDb: true,
});
 
ledger.on('log::error', function(time, msg){
    //do something special with errors
});
  
ledger.on('log::*', function(time, msg){
     //log catchall
});
    
console.log('log');
console.info('info');
console.warn('warn');
console.error('error');
