MongoDb is not connected and I have no error-CodePudding

I've wached multiple tutorials on how to connect mongodb with node.js I've created a free account on mongodb.com, set a user name and a password, created a database, added an IP adress on 0.0.0.0/0

on vsCode i've installed all necessary packages

and here is my code

const express = require('express');
const mongoose = require('mongoose');

const app = express();
const uri = "mongodb srv://user_db:[email protected]/myDataBase?retryWrites=true&w=majority";

async function connect(){
try{
    await mongoose.connect(uri)
    console.log("connected")
    } catch(error){
        console.log(error)
    }
}
connect();

app.listen(3000,()=>console.log("server started"));

The server start but I have no message from mongodb, no errors just nothing happend. I've tried multiple times to rewrite the code, created multiple account from mongodb but always the same result, nothing happend.

I don't have much knowledge about it but maybe this will works because it works in mine case i think doing like this will work try one time

const mongoose = require('mongoose');

main().then(res=> console.log("db connected successfully...!!!"))
main().catch(err => console.log(err));

async function main() {
  await mongoose.connect('mongodb://0.0.0.0:27017/my_server');
}

CodePudding user response：

const uri = "mongodb://<username>:<password>@localhost:27017"

Basically your mongodb will be started in the localhost:27017 but if you have updated the hosting service from localhost to 0.0.0.0 then you should use the ip instead of localhost otherwise the above given uri will work fine.
