Using mongoDB with node.js with the driver

Question

I'm trying to use mongoDB with the driver

I installed mongoDB in windows using this guide https://medium.com/@LondonAppBrewery/how-to-download-install-mongodb-on-windows-4ee4b3493514.
I created a new directory and an app.js. (following this guide https://docs.mongodb.com/drivers/node/master/fundamentals/connection/) In the app.js I pasted this:

const { MongoClient } = require("mongodb");

// Connection URI
const uri =
  "mongodb+srv://sample-hostname:27017/?maxPoolSize=20&w=majority";

// Create a new MongoClient
const client = new MongoClient(uri);

async function run() {
  try {
    // Connect the client to the server
    await client.connect();

    // Establish and verify connection
    await client.db("admin").command({ ping: 1 });
    console.log("Connected successfully to server");
  } finally {
    // Ensures that the client will close when you finish/error
    await client.close();
  }
}
run().catch(console.dir);

In the terminal I opened mongod in the first shell and in the second shell I used the comand "node app.js" inside its directory.

The terminal printed this error:
C:\Users\Feder\Desktop\udemy\FruitProject\node_modules\mongodb-connection-string-url\lib\index.js:105
            throw new MongoParseError('mongodb+srv URI cannot have port number');
            ^

don't use MongoDB URI in SRV format as it requires a hostname and a valid domain name. in your case, you are connecting with localhost which does haven't any domain name. instead of use

const { MongoClient } = require("mongodb");

// Connection URI
const uri =
  "mongodb://sample-hostname:27017/?maxPoolSize=20&w=majority";

// Create a new MongoClient
const client = new MongoClient(uri);

async function run() {
  try {
    // Connect the client to the server
    const connection = await client.connect();
    if(connection){
       console.log("server connected successfully");
    }

    // Establish and verify connection
    // await client.db("admin").command({ ping: 1 });
    // console.log("Connected successfully to server");
  } finally {
    // Ensures that the client will close when you finish/error
    await client.close();
  }
}
run().catch(console.dir);

should I use the code that you posted in app.js? It doesen't print the console.log Connected succesfully

DilipCoder Over a year ago

you can write something like const connection =await client.connect(); if(connection){ console.log("connected successfully to server") }
