How does module.exports work

Question

I\'m using Express and Mongodb to write my first web app and this is probably a noob question, but let\'s say I were to define a user model in a file called users.js and then ca

Answer 1

The standard way to define the model and using the schema in the controller

User.js

 //User Model
var mongoose = require('mongoose');

var userSchema = new mongoose.Schema({
  id: String,
  name: {
    type: String,
    index: true
  },
  email: {
    type: String,
    trim: true,
    index: true,
    lowercase: true,
    unique: true
  },
  mobile: {
    type: String,
    trim: true,
    index: true,
    unique: true,
    required: true
  },
  profilePic: String,
  password: { type: String },
  locations: [{}],
  location: {
    type: { type: String, default: 'Point', enum: ['Point'] },
    coordinates: { type: [], default: [0, 0] },
    name: String,
    shortAddress: String
  },
  address: String,
  gender: String,
  dob: Date,
  signupType: { type: String, enum: ['facebook', 'google'] },
  deviceType: String,
  createdTime: Date,
  updatedTime: Date,
  googleToken: String,
  facebookToken: String,
  fcmToken: String,
  facebookLink: String,
  facebookId: String,
  memberType: String,
  deviceId: String,
  preferences: [{}],
  loginData: [{}],
  token:String,
  isVerified: Boolean,
  isMobileVerified: Boolean,
  isEmailVerified: Boolean,
  lastSeen: Date
});

// 2D sphere index for user location

userSchema.index({ location: '2dsphere' });

mongoose.model('User', userSchema);

module.exports = mongoose.model('User');

UserController.js

//User Controller 
var User = require('./User');


    // RETURNS ALL THE USERS IN THE DATABASE
    router.get('/', function (req, res) {
        User.find({}, function (err, users) {
            if (err) return res.status(500).send({ errors: "There was a problem finding the users." });
            res.status(200).send(users);
        });
    });
