NodeJSでは複雑なデータ構造を管理します.

const mongoose = require('mongoose');

let Schema = mongoose.Schema;

const userIDSchema = new Schema({

UserID: {
    type: mongoose.Schema.Types.Mixed,
  },
  })

const UserID = mongoose.model('UserID', userIDSchema);

module.exports = UserID;

const mongoose = require('mongoose');

let Schema = mongoose.Schema;

const FirstNameSchema = new Schema({

UserID: {
    type: mongoose.Schema.Types.Mixed,

    ref: 'UserId', 
},

First_Name: {

    type: String,

},
  })

const FirstName = mongoose.model('Firstname', FirstNameSchema);

module.exports = FirstName;

const User = mongoose.model('Story', userSchema);

module.exports = User;

const mongoose = require('mongoose');

let Schema = mongoose.Schema;

const userSchema = new Schema({

UserID: {
    type: mongoose.Schema.Types.Mixed,
  },
  User_Info: {
    First_Name: {
      type: String,
    },
    Last_Name: {
      type: String,
    },
    Current_Address: {
      type: String,
    },
    Email_Address: {
      type: String,
    },
  },
      Phone_Numbers: [{
        Home_Phone: {
          type: Number,
        },
        Work_Phone: {
          type: Number,
        },
        Cell_Phone: {
          type: Number,
        },
            Phone_verified: [{
              Home: Boolean,

              Work: Boolean,

              Cell: Boolean,
            }],
      }],

})

const User = mongoose.model('User', userSchema);

module.exports = User;

app.post('/api/user', function(req, res) {
  User.create({
    UserID: req.body.userid,
    User_Info: req.body.userinfo,
    First_Name: req.body.firstname,
    Last_Name: req.body.lastname,
    Current_Address: req.body.currentaddress,
    Email_Address: req.body.emailaddress,
    Phone_Numbers: req.body.phonenumbers,
    Home_Phone: req.body.homephone,
    Work_Phone: req.body.workphone,
    Cell_Phone: req.body.cellphone,
    Phone_Verified:
    req.body.phoneverified,
    Home: req.body.home,
    Work: req.body.work,
    Cell: req.body.cell,
  }).then(user => {
    res.json(user)
  });
});

const bodyParser = require('body-parser');

app.use(bodyParser.urlencoded({
  extended: true
}));
