ReferenceError: TextEncoder is not defined Node.js with mongoose

Question

the problem seems to be with mongoose & mongodb packages as it works fine when

mongoose.connect('mongodb+srv://mydb:<password>@cluster0.w1opr.mongodb.net/test?retryWrites=true&w=majority');

is removed it also works fine on repl.it cloud env here is my code

var express = require('express');
var ejs = require('ejs');
var app = express();
var bodyParser = require('body-parser');
var mongoose = require('mongoose');
mongoose.connect('mongodb+srv://mydb:<password>@cluster0.w1opr.mongodb.net/test? 
retryWrites=true&w=majority');
app.set('view engine','ejs')
app.use(bodyParser.urlencoded({extended: true}));
.
.
.
app.listen(3000,function(){
console.log('Server is running on port 3000');
});

Actually mongoose 6 requires Node 12 or higher, so this is expected behavior. Mongoose 6 does not support Node 10.So updating Node version will fix the issue. It also fix the problem by downgrading mongoose version to 5.
