I'm new with nodeJS and MongoDB. I have this code:
var fs = require('fs');
var mongojs = require('mongojs');
var db = mongojs('monitor', ["configurations"]);
fs.readFile('json/object1.json', 'utf8', function (err, data) {
    if (err) throw err;
    console.log(data);
    db.configurations.insert(data, function(err, doc) {
        console.log(data);
    if(err) throw err;
  });
});
no data insered to the mongodb, and I've got no error. the both console.log(data) print the json string as well.
