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');
});

Answer 1

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.

Answer 2

Check your node version, if it's lower than 12 it won't work, if that's the case updating node should do do the job. You could downgrade your mongoose version too.

There's an issue closed on Mongoose github page. https://github.com/Automattic/mongoose/issues/10638
