Complete MongoDB Tutorial #16 - Connecting to MongoDB

why don't simply use "const mongoose = require("mongoose");
const connect = await mongoose.connect(connection_string)"

About that CB function , couldn't we just put it in THEN and with no property ? , if the connection successfully established we will listen to the port if not we just won't do anything

why you export 2 functions while you can use cb(err,db) with 2 parameters, return cb(null,db) when no error. if there is an error return cb(err)

Connecting to a MongoDB database in NodeJS; so beautifully explained. Thanks, Shaun.

👍

the err var at the cb will be undefined and not null :)

grtting error in this line: dbConnection = client.db(); Error: "Error [MongoError]: database name must be a string"

Thank you so much for creating this session, I have seen lot of mongodb connection but they max are using mongoose and either they are not creating one db as dynamic and globally available but your this session helped me now I am stopped my searching.
Thanks a lot!!!

why couldn't we just call dbConnection as getDb and cal that getDb instead of putting dbConnection into a function and call thta function?

Why you need to use "return cb()" instead of "cb()"?

I get error: SyntaxError: Unexpected token, when: const { MongoClient } = require('mongodb');
Can you please help me to fix it! Thank you so much.

Sir, please what's your vscode theme? i like the IDE coloring

Try to replicate the tutorial, but get error:

TypeError: connectToDb is not a function

Not only mongodb conn, you taught node,callback, promise everything so nicely!
Thanks MAN!

Great tutorial thanks. But where is the connection string found in Atlas? And where do you place the username and password? Is bookstore the database or collection name?

this is like 5th time trying to connect and find the collection and it's just not working. This time im using exact same code

I'm not gonna lie I have no idea what's going on anymore but at this point I think I'm just supposed to stop forcing myself to clearly understand everything and just get the practice in.

Case anyone feels alergic to .then().catch() here's my async/await code:
const { MongoClient } = require('mongodb');

let dbConnection;
const uri = 'mongodb://localhost:27017/bookstore';

// Connect to the database
exports.connectToDb = async (cb) => {
// a callback function is passed, and it will be executed when the following task is completed.
try {
const client = await MongoClient.connect(uri);
const dbConnection = client.db();
return cb();
} catch (error) {
console.log(error);
return cb(error);
}
};

// Return the database connection so we can play with it (make queries)
exports.getDb = () => dbConnection;

Do you ever have a sale on your annual pro plan? It's a great price don't get me wrong, just at a frugal point in my life --- yet I love your teaching style and want to pay for the learning buffet you've put out for me.

What is the difference between connecting with the MongoClient from the mongodb package and connecting with mongoose.connect() with the mongoose package?

I have a question, Why do we return the callback? why not just call it?

OK I see why people would rather use Mongoose over the native driver now.

It's not about mongodb driver ,it's all about express and server creation I wait for the next episode today ,please

Please also include mongodb aggregation framework with mongooses or mongodb driver (filtering and sorting sub document arrays) geojson. It would be very helpful 🙏🙏

This is fantastic, you make it all so easy to understand!

Thank you!

i love this new mongodb tutorial but if you make a mongoose tutorial as well it will be fantastic
