simple-log-tee

Log, and write, to multiple streams at the same time.

This is really handy for logging output to the console and to a file at the same time.

usage

var stee = require('simple-log-tee');

var doubleStd = stee.createLogTee([process.stdout, process.stderr]);
doubleStd.log('Double the fun?');
doubleStd.write(' ... ');
doubleStd.log('Maybe not.');

stee.teeToStdoutOnly().log('That\'s better.');
stee.teeToNowhere().write('But this is going nowhere!');

var dualRecorder = stee.createLogFileTee('test.log');
dualRecorder.log('Writing to "%s" and stdout.', dualRecorder.logfile);

var recordStream = dualRecorder.getFileStream();
recordStream.write('This is SECRET and only going in the file!\n');

var fileOnly = stee.createLogFileTee('t2.log', null);
fileOnly.write('one line, only in ' + fileOnly.logfile);

Note: as of version 0.2.0, the API has been changed to no longer export classes that you create with new, but functions that create the objects for you.
Replace new stee.LogTee([stream1, stream2, stream3]) with stee.createLogTee([stream1, stream2, stream3]).
Replace new stee.LogFileTee('my.log') with stee.createLogFileTee('my.log').
