You can override original console.log function, take a look at this :

Object.defineProperty(console, "toFile", {
    get : function() {
        return console.__file__;
    },
    set : function(val) {
        if (!console.__file__ && val) {
            console.__log__ = console.log;
            console.log = function() {
                var fs = require('fs');
                var msg = '';
                for (var i = 0; i < arguments.length; i++) {
                    msg += ((i === 0) ? '' : ' ') + arguments[i];
                }
                if (msg) {
                    fs.write(console.__file__, msg + '\r\n', 'a');
                }
            };
        }
        else if (console.__file__ && !val) {
            console.log = console.__log__;
        }
        console.__file__ = val;
    }
});

Then you can do this:

console.log('this will go to console');
console.toFile = 'test.txt';
console.log('this will go to the test.txt file');
console.toFile = '';
console.log('this will again go to the console');
