The Mongoose Error occurred due to a timeout in buffering that lasted for 10,000 milliseconds

Question

The Mongoose Error occurred due to a timeout in buffering that lasted for 10,000 milliseconds

I am attempting to establish a connection to Mongodb using the Thunder client extension in Vs code.

Here is the code snippet I have implemented so far, but unfortunately, I am encountering an error that causes the application to crash.

const mongoose = require('mongoose');

const mongoURI = "mongodb+srv://****:****@cluster0.jswzjap.mongodb.net"

const connectToMongo = ()=>{
    mongoose.connect(mongoURI, ()=>{
        console.log("Connected to Mongo Successfully");
    })
}

module.exports = connectToMongo;

The above snippet represents the connection string for MongoDB.

[nodemon] 3.0.2
[nodemon] to restart at any time, enter `rs`
[nodemon] watching path(s): *.*

This pertains to the specific error message that I am currently facing.

Answer №1

Make a modification to your db.js file by turning it into an async function:

const mongoose = require('mongoose');

const mongoURI = "mongodb+srv://****:****@cluster0.jswzjap.mongodb.net"

const connectToMongo = async ()=>{
   try {
      // await the connection
      const con = await mongoose.connect(mongoURI);
      console.log(`Connected to mongodb: ${con.connection.host}`);
   } catch (error) {
      throw error;
   }
}

module.exports = connectToMongo;

Next, ensure to call the function within your index.js. Simply importing it with require is not sufficient:

const connectToMongo = require('./db'); 
const express = require('express');
const app = express();
const port = 3000;
app.use(express.json()) // for parsing application/json 

// Invoke the connectToMongo function
connectToMongo().then(()=> {
   console.log('Connected to db');
}).catch(e => {
   console.log('Error Connecting to db: ', e);
})
  
// Navigate through available routes 
app.use('/api/auth', require('./routes/auth'));
app.use('/api/notes',require('./routes/notes'));
app.get('/', (req,res)=>{   res.send("hoo") });
app.listen(port, () => {   
   console.log(`Example app listening on port http://localhost:${port}`) 
});
