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

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.😌

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

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!

Sir please tell us about new react JS series any idea when it's starting?

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

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

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

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

Tenks😊 gruudev

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

How can I get a token set in cookies in browser

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

21:06 but token match karne ke liye database access chahiye hoga na har bar request aane par!!..........to problem to same hi rahi jo aapne video ke starting me kaha tha

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

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

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.

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,

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..

Same.

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

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

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

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
