You should have watched from the beginning of the playlist.This is probably the best NodeJS course out there.I regret buying shit courses on udemy when such a gem was already =available on UA-cam that too for free.I wish he covered more advanced topics.
If i can't use getuser method in middleware and call next() method it is login successfully and cant redirect me to login page and it is normally work Please i cant understand why its happen please solve my qustion😢
SIr on deployment why user persistence not there ? means after one time logged in in any device i can generate url in another device also without logged in ?
automatically mongodb me collections vaise hi create hota hai ... for example: const URL = mongoose.model("url", urlSchema); => show collections => urls for example: const User = mongoose.model("user", userSchema); ==> show collections => users model me tum koi aur name dalo aur mongosh me jake show collection karoge to tumhe dikhega
big problem with this playlist is continuing with the same example code from previous session ..it causes problems if you are stuck with simple things like those packages like nanoid and shortid
Please create a video on google-reCaptcha v2 verification in a registration form to avoid scripting much need and it is not available on any channel where an API is made for that please please make it if possible
hmm, It seems like you merge two lecture in one video(authentication & cookie). for the first time, cookie implementation is much difficult then authentication.
I didn't like this specific video of yours , most of the time , you were just coding and saying " mai ye kar dunga" but you didn't explain why , and what's the purpose . It's compelling me to just copy and paste whatever you are typing without understanding and I absolutely hate this copy and paste. These topics are crucial and deficult for beginners like me who are just getting started with backend. Please elaborate thingy and be little bit slow and make us beginners understand so that we can implement this knowledge on our own.

why you don't explain anything like why you are using controller and what is that and other stuffs
He already explained in his previous videos in the playlist.
He explained. Its not his peonlem that you didnt watch properly and just jumped to auth
It's because you should learn nodejs first instead of just Watching tutorials
MVC framework he is using for development
You should have watched from the beginning of the playlist.This is probably the best NodeJS course out there.I regret buying shit courses on udemy when such a gem was already =available on UA-cam that too for free.I wish he covered more advanced topics.

Object Id create karte time apne ref: 'users' liya hai user ki jagah. Phr bhi ye work kar rha h. Why ?
automatically mongodb me collections vaise hi create hota hai ...
for example: const URL = mongoose.model("url", urlSchema);
=> show collections => urls
for example: const User = mongoose.model("user", userSchema);
==> show collections => users
model me tum koi aur name dalo aur mongosh me jake show collection karoge to tumhe dikhega
@@sanketmane4026 ha agar User/user ho toh users hota he.
Eg: Giraffe/giraffe/giraffes=> giraffes (in mongo)
Monkey/monkey/monkeys=>monkeys (in mongo)
can anyone help me achieve this without mongodb just with ,json file for storing data
nicely explain
Sir setting user details in cookies would be done with express-session by default right?
Well explained... Where I can get the code for reference

What language do you speak?
Hindi

32:00
It would have been better if u would use postman or any server client
hmm, It seems like you merge two lecture in one video(authentication & cookie). for the first time, cookie implementation is much difficult then authentication.
Damn Bro!
bhai yrr ejs mat use krna kro na pls real world me kya use h iska
Matlab?
Bro he already explained in his previous videos
My girlfriend 🤣🤣🤣🤣🤣
What an Easter egg hidden here haahahahaha
If you make this video in English it's going to be great,
Learn Hindi it's not that hard
Bro use postman so that u don't have to waste time on creating FE as this video is totally focused on Node JS
I mean, he's also giving us an idea about SSR 🤷🏿♂️
@@pranaavbv9359 ok nniga
Everything is moving so fast, it's going over my head.
Sir, please first try once before video, instead it's so confusing
I didn't like this specific video of yours , most of the time , you were just coding and saying " mai ye kar dunga" but you didn't explain why , and what's the purpose . It's compelling me to just copy and paste whatever you are typing without understanding and I absolutely hate this copy and paste. These topics are crucial and deficult for beginners like me who are just getting started with backend. Please elaborate thingy and be little bit slow and make us beginners understand so that we can implement this knowledge on our own.
Bhai, Tu god hain kya?
zip file of knowledge
Speak to English everyone understand please Because i don't know Hindi

if your video is not in english? so why are you writing the title in english??!! take my downvote
Learn Hindi
well...... there are lots of people like me over India who can understand hindi but can't read it properly so for me it's fine as it is
Learn Hindi. It's not that hard. We learned English. Did we complain?
