Question

I am learning and trying simple example using node.js and mongoskin. here is my function below

Problem following function is, if the mongodb server is disconnected then also I get the “err=null” hence not able catch connection error. If I restart node.js server (while mongoDB server is still disconnected) I get error as
“[Error: failed to connect to [server-aa070:27017]]”

// Process messages from client
   app.post('/send', function(req, res){
   var message = {
        id: i++,
      nickname: req.param('nickname', 'Anonymous'),
          text: req.param('text', ''),
created_at: new Date()
};

conn.chat_log.insert(message, function(err) {
   if(err!==null){
   console.log(err);
   }
   else {
    console.log(message);
    console.log(err);
   }
});
res.json({status: 'ok'});
});

I’m new to node.js and mongodb, but why are you using if(err!==null) rather than if(err)? If I’m understanding correctly, wouldn’t this solve your problem?
