homePage.create is not working. i think my problem is here "mongoose.connect('mongo://localhost:27017/Socialuser', { useNewUrlParser: true, useUnifiedTopology: true });"

App.js file

          const express = require('express');
            const bodyParser = require('body-parser');
            const mongoose = require('mongoose');
            let homePage = require('./models/home');
            
            mongoose.connect('mongo://localhost:27017/Socialuser', { useNewUrlParser: true, useUnifiedTopology: true });
            
            const app = express();
            
            app.use(express.static(__dirname + '/public'));
            
            app.get('/', (req, res) => {
                res.render('landing.ejs');
            });
            
            app.get('/login', (req, res) => {
                res.render('loginSignUp.ejs');
            });
            
            app.get('/home', (req, res) => {
            
            
            
                console.log(homePage);
                homePage.create({ name: 'wasim', image: 'https://www.w3schools.com/w3css/img_lights.jpg' }, (err, home) => {
                    if (err) {
                        console.log(err);
                    } else {
                        console.log('saved');
                    }
                });
            });
            
            app.listen(3000, () => {
                console.log('server started at port 3000');
            });

here is my home.js file.it's the home schema file

    const mongoose = require('mongoose');
    
    let homePageSchema = new mongoose.Schema({
        name: String,
        image: String
        // comments: [ String ]
    });
    
    module.exports = mongoose.model('Home', homePageSchema);

    1) Please use this 
    
    mongodb://localhost:27017/Socialuser
    
    Instead of -
    
    mongo://localhost:27017/Socialuser
    
    2) mongoose.connect("mongodb://localhost:27017/[yourDbName]", {
      useUnifiedTopology: true,
      useNewUrlParser: true
    });
    
    In your case yourDbName = Socialuser

Hope this will solve your problem!
