I am a newcomer on this segment. I try to install mongodb on my computer, then its completed and added all bin path to the environment variable . I have tried to use mongodb in several ways, but I cannot solve the issue.
I have written this code and try to run, unfortunately it throws an error:
const MongoClient = require('mongodb').MongoClient;
MongoClient.connect('mongodb://localhost:27017/animals', (err, client) => {
if (err) throw err;
console.log('works!!!!');
// const db = client.db('animals')
// db.collection('mammals').find().toArray((err, result) => {
// if (err) throw err
// console.log(result)
// })
})
The error is :
PS D:\Nodejs Works\beginner works\mongo db works> node app
D:\Nodejs Works\beginner works\mongo db works\node_modules\mongodb\lib\sdam\topology.js:278
const timeoutError = new error_1.MongoServerSelectionError(`Server selection timed out after ${serverSelectionTimeoutMS} ms`, this.description);

Now, I can not understand, how to overcome from this problem, and connect with mongodb.
I think mongdb working on computer properly, because from task manager Services there I can see mongodb as running on background.
When I write in command line: mongosh, its give an output that is:
PS C:\Program Files\MongoDB\Server\6.0\bin> mongosh
Current Mongosh Log ID: 64a6b08ac9697a1d4724af54
Connecting to: mongodb://127.0.0.1:27017/?directConnection=true&serverSelectionTimeoutMS=2000&appName=mongosh+1.10.1
Using MongoDB: 6.0.7
Using Mongosh: 1.10.1
For mongosh info see: https://docs.mongodb.com/mongodb-shell/
------
The server generated these startup warnings when booting
2023-07-06T16:19:36.122+06:00: Access control is not enabled for the database. Read and write access to data and configuration is unrestricted

test>
Then when I am writing 'mongod', its showing:
