项目

db.js

var mongoose = require(‘mongoose‘);
mongoose.connect(‘mongodb://127.0.0.1:27017/whhhh‘, { useMongoClient: true });
var db = mongoose.connection;
db.on(‘error‘, console.error.bind(console, ‘connection error:‘));
db.once(‘open‘, function (callback) {
    console.log("数据库成功连接");
});
module.exports = db;

try.js

var User = require("./user.js");

/**
 * 插入
 */
function insert() {

    var user = new User({
        username : ‘zhangxiao‘,                 //用户账号
        usersex: ‘nan‘,                            //密码
        userage: 17,                                //年龄

    });

    user.save(function (err, res) {

        if (err) {
            console.log("Error:" + err);
        }
        else {
            console.log("Res:" + res);
        }

    });
}

insert();

　　user.js

  var   Schema=mongoose.Schema;

var UserSchema = new mongoose.Schema({
