Simple node.js based logging server using express and Winston

server.js

// requirements
var winston = require('winston');
var MongoDB = require('winston-mongodb').MongoDB;
var express = require('express');

// set up winston
winston.add(MongoDB, {db:'winston'});
winston.remove(winston.transports.Console);
winston.emitErrs = true;
winston.handleExceptions(new winston.transports.File({ filename: 'exceptions.log' }))

// set up express app
var app = express();
// found out the hard way that this middleware is required to parse data
app.use(express.bodyParser());

// routing
// note: urls not implemented will serve 404 not found
app.all('/api/log', function(req, res){
  res.status(301).redirect('/api/v1/log');
});
app.get('/api/v1/log', function(req, res){
  res.send(500, { error: 'GET not implemented in v1' });
});
app.post('/api/v1/log', function(req, res){
  var required = ['appname', 'logname', 'source', 'logentry'];
  for(param in required){
    if(! req.param(required[param])){
      res.send(500, { error: required[param]+' is required' });
      return false;
    }
  }
  winston.info('Winston Logging', req.body);
  res.send('Thanks for that, '+req.body.appname);
});

// start server
app.listen(8888);
console.log('Listening on port 8888');
