如何阻止Node.js打印数据到控制台？

Question

I have this Code in node

var io = require('socket.io'), connect = require('connect');

var pg = require('pg');

var connectionString = "Some connection string";  

var app = connect().use(connect.static('public')).listen(3000);
var chat_room = io.listen(app);
var DataArrayRows=[];

setInterval(function(){
       pg.connect(connectionString, function(err, client, done) {
        client.query('select * from jctsl_get_all_notifications_v1()', function(err, result) {
            DataArrayRows=result.rows;
            done();
        });
       });
},10000);

chat_room.sockets.on('connection',function(socket){
  chat_room.sockets.emit('entrance',{message:DataArrayRows}); 
  setInterval(function(){
      chat_room.sockets.emit('entrance',{message:DataArrayRows});   
  },10000);    
});

In the code, I've not written any console.log() statement but still on every request to database, the returned rows are displayed on the console window.

How can I stop node from doing that?

Answer 1

Set the log level lower

var chat_room = io.listen(app);

chat_room.set('log level', 0);

The log level defaults to 3
The amount of detail that the server should output to the logger.

0 - error
1 - warn
2 - info
3 - debug
