Collection in express using mongoose

Question

I am using express js with mongoose and saving data into users collection but i want to know how can i change collection name ? Here is my code

app.post('/signup', (req, res, next) => 
{
    var mongoose = require('mongoose');
    mongoose.connect('mongodb://localhost:27017/cuts');
    var User = require('./testing.js');

    var newUser = new User();
    newUser.name = req.body.name;
    newUser.email = req.body.email;

    newUser.save((err, User) => {
            if (err) {
               console.log(err);
            }
            else {
                   console.log("Signup Successfully");
            }
        });
});

Here is my testing.js

var mongoose = require('mongoose');
var UserSchema = mongoose.Schema({
    name : {
        type : String,
        required : true
    },
    email : {
        type : String,
        required : true,
        unique: true
    }
});
const User = module.exports = mongoose.model('User', UserSchema);

Answer 1

Collection name is fetched from Model itself. Please changing model name.

Change this

const User = module.exports = mongoose.model('User', UserSchema);

to

const User = module.exports = mongoose.model('NewUser', UserSchema);

If you are trying to renaming the existing User collection, use

const mongoose   = require('mongoose');
mongoose.Promise = Promise;

mongoose.connect('mongodb://localhost/cuts').then(() => {
  let db = mongoose.connection.db;
  return db.collection('User').rename('NewUserColl');
}).then(() => {
  console.log('rename successful');
}).catch(e => {
  console.log('rename failed:', e.message);
}).then(() => {
  console.log('disconnecting');
  mongoose.disconnect();
});

Go To your model and change your schemaname

const User = module.exports = mongoose.model('User', UserSchema);

To

const User = module.exports = mongoose.model('NewUser', UserSchema);

Mongo Db by Defaults take plural name of your schema name.
