The thing I love about this playlist is using simple language, very easy to understand and please always give the scenario of how things work at enterprise level in your future video.😌

[@weforyouweb1165]

Bro you are explaining very deep things in practical superb bro 🎉🎉

[@pradeeppop8201]

This tutorial of nodejs is more useful to any other paid tut . Thank you so much sir such a amazing series ❤️ 🙌 👏

[@santoshdhariwal8979]

Excellent Videos Piyush... Explaining it in such a simple way.. makes it so easy

[@mahendra.k12]

If you encounter this error: Cannot read properties of undefined (reading 'split'), Follow the given steps: 1. first make changes only to handleLogin controller and send token as json instead of setting a cookie. 2. Now in postman, make POST req to /user/login and generate a token. 3. Now make change to our middleware functions i.e to checkAuth and restrictLogin middlewares. 4. And now finally make GET req to homepage and set the authorization header in postman. Reason: If you make changes to the middlewares first and then try to generate the token it will result in error because we don't have authorization header during initial token generation and the checkAuth middleware is still executed. Hence generate the token first and then make necesarry changes in the middlewares. Hope it helps!

still getting the same

No words, how you explain deep fully, at each word meaning fully explain😊 Thank you, Create An KZbin channel and share your knowledge📚

Thanks sir taking my doubts..it's clear now

[@Muzafar.A]

that was so useful and deep knowledge for newbie. awesome bro ❤.

[@imPrathamDev]

can you explain refresh token and access token?

[@Solo_playz]

I thought the same even though I used to do the same in my MERN stack projects what shubham has asked But Thanks Piyush for getting us more clear on it also I found that OAuth and NextAuth use the same technique while authenticating users on each request they utilize tokens stored in the cookies and get users' data from it! Very very useful topic you have covered

[@ravisingh5906]

i can't set cookie by res.cookie

[@sawaregamer8815]

use cookie parser and if you work on react and node you need to use cors package

[@DineshKumar-gt7xm]

​​@@sawaregamer8815I am also not able to set cookies using react. I have used both cookie parser and cors package.

[@muhammadtaimoor2378]

im facing problem regarding non existing authorization header in server side gives Cannot read properties of undefined (reading 'split'), though using res.set('Authorization', `Bearer ${token}`); inside handleUserLogin async function to set the valus, help me to debug it any one...

[@mayankbadika3101]

Thank you so much for sharing this. Very good explanation :)

[@yogeshoceanmtech]

how to get this code

[@himanshuarora1910]

you should set the headers in ejs files only ,whats the use of creating them if we have to use postman only

[@amanmaddhesia120]

Too good brother

[@Abdullahsiddique-wf2nt]

Agr hum Map or database ko combined use kry tu excess database request ka issue ni hoga, first time jab user login hoga tu map ma bhi or database ma bhi store hoga or getuser ma hum check laga day ka agr user exist krta ha map ma tu database sa query na kry or agr map sa ma ni ha tu database sa query kr kay usko map store krdy for further request verification

[@Ajmal_Hossain]

Another potential concern might arise when dealing with stateful authentication in the context of load balancing.

[@Rij-k6p]

in browser based applications, in industry standard for authentication tokens are sent through cookies or response?

[@CodeWavewithShahHussain]

But jwt be to scrent check krna ka liya br br new page reload phr datbase wala sa match krta ha?

[@jackma9528]

sir in my code it is showing can't read the properties of undefined after i switched to response section after cookie section, i copied exactly your code but it is not working, if someone know please help

[@tarushchandra8993]

Hi Piyush, maine ek website banai hai jiska server or client different domain pe hai but jab mai sever me cookies ke option me domain ko apne client ke domain pe set karta hu, tab bhi cookie send nahi ho rahi. I've also used cors for cross platform sharing. kya browser ka kuch default behavior hota ki third party client par cookie send nahi karna? meanwhile maine localstorage me token send kar diya, but mai cookies me token send karna chahta hu..

​@@DineshKumar-gt7xm did you?

[@NOVAGAMING_08]

​@@BiGryuuu add with credentials: true in your frontend code and in backend use cors ( app.use(cors({ origin : '*', credentials: true, })) I think this might work for you

[@jatinsharma3792]

I am looking for the content on CSRF and CSP Headers in JAVA Filter. If you could provid it that would be really helpful.

[@AkashLayal]

Sir i have a doubt because 11:04 you have directly providing user from jwt token but if the user is deleted from database but the user can still access logged in content.

[@vishnugopalakrishnan9539]

getUser function doesnt "provide" user directly, it decodes the user data that was signed, i.e. id and email, adds it to req.user (code under restrictToLoggedInUser ) and finds that info from the database for each req, you can check the code at router.get('/'..) under staticRouter,

[@rishabhgupta9846]

Are you checking whether entry is null or not

[@utkarshtenguria3836]

but first time in mobile device we have to login how can we send token in request in first time does it not required?

[@DozSparrow]

First time we need to login, after successful login server provide us token and subsequent we use provided token by server to communicate server

[@ApurvaKalvadeSDE]

if one user logs in, but second user comes and copy your Authorization Bearer token or Cookie..... and that 2nd person then requests in the backend from his own laptop via the copied token/cookie. In this case, how to make it more secure ???? Can you please walk through this scenario ?

[@Rahul-yr3up]

He has said in his video that do not pass exact jwt token in cookie. Encrypt the token before passing it to the cookie

[@rishabhkedia9304]

In last, we use header base authentication, Will it work for browser? Because, it is not working for browser in my case.

It's a way in which bearer token is designed

Hi.. Need your help.. My req.headers does not contain authorization property

[@Solo_playz]

Bro! You have to set your headers on your own like this that contain Authorization property here is the example! const headers = { 'Authorization':'Bearer ', 'Content-Type:'application/json', // just an example property you can add more property as you want! } now you can pass this header with your fetching methods like fetch or Axios Hope you get it

[@pratyushpragyey7002]

well if you're using postman then you've to set the bearer token by going in headers
