Thank you very much, keep them coming ❤
appreciated 💯... sir
Also make tutorial on nodejs framework(nestJs).
thanks a lot piyush sir great teacher and mentor
Please try to make/create separate code for each ep if possible. Bcz it is difficult to connect to your video in-btn. Means I'm watching this vdo directly of your series and it is difficult to connect with your explanation bcz you are doing changes in your code which is written in previous videos.
No doubt Ur explanation is very good and I'm very excited to learn from U.
Instead, right now you can create copy of previous videos:)
Is there any github repo for this code, so that i can have starter code and code along this tutorial ?
thanks alot finally got it how it works

I am not able to install mongodb and mongosh on my ubuntu 22.10. I searched a lot but there were no mention of ubuntu 22.10 or 22.04lts on even offical docs.
So i am using atlas and compass.
Are you going to teach these ?
To install MongoDB on Ubuntu 22.10, you can follow these steps:
1. Import the MongoDB public GPG key:
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 4B7C549A058F8B6B
2. Create a list file for MongoDB:
echo "deb [ arch=amd64,arm64 ] repo.mongodb.org/apt/ubuntu focal/mongodb-org/4.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.2.list
3. Reload the local package database:
sudo apt-get update
4. Install the MongoDB package:
sudo apt-get install -y mongodb-org
5. Start MongoDB:
sudo systemctl start mongod
6. Verify that MongoDB has started successfully:
sudo systemctl status mongod
7. Download the mongosh package from the MongoDB website.
curl -LJO github.com/mongodb/mongosh/releases/download/v1.0.0/mongosh-1.0.0-linux-x86_64.deb
8. Install the package using dpkg
sudo dpkg -i mongosh-1.0.0-linux-x86_64.deb
Then just run mongosh
@@piyushgargdev thank u, worked for me..
Thanks bro
Appreciated
Can you please share the source-code for this program.
Sir you should also give code if you give code then it will be very easy for us for coding
Sir I want to ask here that how can I connect mongoDb if I am doing it for the website of my client, because here we are saving data in our local machine but what if I want data to be saved in my clients computer. Please give me solution.
You need to use cloud services then. It's just about having a machine online that runs on cloud.
Sir will you upload a complete course of mern stack?
Yes 😄
Hi Piyush, we really appreciate the efforts you've put into creating these awesome tutorials. In this particular video, it would be helpful if you've also shared solution to two problems:
1) POST request with duplicate email crashes the server, how do we handle error here?
Since we've defined Mongoose schema with email: {required: true}, it throws an error and the server gets crashed if we put in the same/duplicate email id again -> as shown in your video as well. But what is the solution for this?
Also,
2) We are using MongoDB id creation value to find the database items. If we create our own custom id, ho do we fetch the data then? I am sure findById, findByIdandUpdate, findByIdandDelete methods won't work in this scenario. Using the Mongoose created ID is too long and not feasible to use.
use try and catch method it will handle the server crash case
same issue bro
@@vivekraiyani63 using Try and Catch method solved the problem
1st check for email if it already exists then throw and error message and if not then proceeds further
Add a middleware to check if the user already exists before proceeding to the insertion.
Are required: true and unique: true not valid now??
this request takes too long to process it is timed out by the server in nodejs mongodb
Mai shared hosting use kar Raha hu jisme Nodejs 20.3.1 hai aur Maine apni Nodejs website ko version 21 par banaya hai... Kya ye MongoDB connection string ki problem hai...?? Ye kaun si problem hai aur kaise sahi Karu... Please guide me ..

hii piyush ... i m getting this error [nodemon] app crashed - waiting for file changes before starting...how to resolve this please suggest

@@pranjalmaurya3832 nhh bhai didnt got the solution
Yes I am also getting this
@@nirmalchouhan3112 stop the nodemon using ctrl+c and read what error u got if i am not wrong ur mongod is not running in terminal so use mongod in terminal and then open another terminal and run mongosh in it and try restart ur nodemon file
can we get the codebase or github link for this
Why do you need that? Are the tutorials not enough to make you understand everything? If not, you need to really work on the basics first because this is indeed a very basic video
Here we are using blocking code while working with database. I assume it's ok for small application but when data becomes very large who we will handle that ? Onw way might be to use promises and on then we can send response. is there any other way ?
At the end, he literally said that we are going to refactor the code according to industrial standards. Looks like you missed that part
bhaiya mongodb connect karne ke baad mongodbconnected likha nhi aarha aur ulta mongoose server selection error aa rha hai topology vaguer se related, please help!

Sir, phone, email should not be same but user name, Hobbies, gender, Image could be same.... Kindly guide me... I am beginner
5:19 gender should be a enum but in 2024 I think String would be better 😂😂😂😂
code for patch method
patch(async(req,res)=>{
//edit an existing user
const id = req.params.id;
const body = req.body;
try {
const user = await User.findById(id);
if (!user) {
return res.status(404).json({ status: 'Error', message: 'User not found' });
}
// Check for changed properties and update only those that exist in the request body
Object.keys(body).forEach((key) => {
if (user[key] !== undefined) {
user[key] = body[key];
}
});
await user.save();
return res.json({ status: 'Success', updatedUser: user });
} catch (err) {
return res.status(500).json({ status: 'Error', message: 'Internal server error' })}
})
im crying
Why?

What kind of stupid you are my dear brother is he mentioned that video is in English?
app.delete("/api/users", async (req, res) => {
await User.deleteMany({});
return res.json({ msg: "I screwed up your database, haha" });
}); 😁😁just intendly deleted all users, don't try hehe
