Hello all,
Am new to mongodb, am frustrated by this connection in all my 3pcs it only connects in one pc.
I have search for solution on internet to replace on localhost:27017 with 127.0.0.1:27017 or with 0.0.0.0:27017
I have installed latest mongodb 7.0.5 and shell and compass
am get no results Below is the code am just want to see “Great Connection” on terminal:
const MongoClient = require('mongodb').MongoClient
MongoClient.connect('mongodb://127.0.0.1:27017', (err, db) => {
if (err) throw err
console.log("Great Connection");
// db.collection('mammals').find().toArray((err, result) => {
// if (err) throw err
// console.log(result)
// })
})
*** Running the code returns the following error:**
C:\Users\Graphics07\Desktop\node\node_modules\mongodb\lib\sdam\topology.js:276
const timeoutError = new error_1.MongoServerSelectionError(`Server selection timed out after ${options.serverSelectionTimeoutMS} ms`, this.description);
