Encountering issues with connecting to the MongoDB server through Node.js

When working with MongoDB in Python, everything runs smoothly without any errors. However, when using Node.js, an error keeps popping up. Can someone please guide me on how to resolve this issue?

Below is the code snippet for the program:


import { MongoClient } from "mongodb";
import assert from 'assert';

const url='mongodb://localhost:27017';

const dbname='myProject';

const client =new MongoClient(url);

client.connect((err)=>{
  assert.equal(null,err);
  console.log("connected successfully");

  const db=client.db(dbname);

  client.close();
});

Here is the encountered error:


const timeoutError = new error_1.MongoServerSelectionError(`Server selection timed out after ${serverSelectionTimeoutMS} ms`, this.description);
                                     ^

Potential solution to this error

Answer №1

It appears that there may be some IP configuration problems, so consider using 127.0.0.1 instead of localhost. This should resolve the issue.

Alternatively,

You have the option to specify the bindIp in your MongoDB configuration as

net:
   bindIp: 127.0.0.1, ::1
