Models in express

Steps involved in creating models in express js

• First we need to import mongooose

• To make it modular, Lets create a new folder named models and then create a new js file . In this example I am creating model named  user. It has 2 properties firstName and lastName.
• Load the model into mongoose

var mongoose =require('mongoose')
//Model for fetching users
var userSchema=mongoose.Schema({
    firstName:{
      type:String,
      required:true
    },
    lastName:{
      type:String
      
    }
});
//User Model
module.exports=mongoose.model('User',userSchema)

• Import the model and then we can load it as needed.

//Load the model for users
User=require('./models/user');

//Using find to fetch all the users in the db
app.get("/api/Users",function(req,res){
  User.find({},function (err,user){
    if(err)
    {
       console.log(err);
       res.send(err);
    }
    else
   {
     console.log(user);
    res.send(user);}
  });
});
