A small bug in code, if (!(username || email)) . Jab video dekhoge to aa jayega smjh. GIthub pe b add kr diya h code. Next video me krte h discuss hitesh.ai/whatsapp

Todo's for login ( dnt know if its good ) - take input from the user from the login page. - save it in a variable - apply check ( as per js series form handling part ) if the username == username && password == password . Then perform some action. - call mongodb to check the db if there is any user with the same username ( email in case ) is present or not , if not throw err . And redirect to register (dnt know how, will plan if situation arise) - if username/email present. Then get its _id and store it in variable - retreive username and pass from that variable to check if both are same or not. If no then err - if yes then redirect it to the page we want ( Dnt know the use of refresh token. Actually i didnt get it by now. I hope I will understand after seeing how u are using it ) , now continue to the video... -

Hello Sir, after 7 years I started coding again, because of some financial issues i cannot pursue my studies, and i have to work in another field because of availability of other jobs. I manage my time at night to gain my knowledge in coding and YOU are the main reason Sir. Thank you.

Login user todo 1- get values from client side 2- validation- emptiness checking 3- check user exist if not redirect to register page 4- assigning of access token 5 -login 6- success response

I have more than 4 year experience on watching tech video on KZfaq in Hindi language.....I can say that this Hindi KZfaq channel is top of all Hindi KZfaq channel.... Amazing sir aapke samjhna ka tarika pasand aaya...very beginner level. Thank you sir thank you very much❤❤

I've never understood backend better until I found your videos. Their clarity and enthusiasm make learning a joy!

Sir, feeling so lucky to be a part of this community. Literally, Chai and Code is an emotion 🔥🔥

Steps for User to Login : 1. get data from user 2. check the data if it is not empty 3. check the data from user to match with that of database. 4. if the data is matched return true else if return false.

I contributed a comment, q ki Target 🎯 to achieve karna aur karvana padega na Thank you sir❤❤😊

It's a challenge to completely understand this, because it is the very first time I'm seeing these methods, and that too a lot of them in a single video. But at least I'm getting the motive behind each action that we are taking. Thanks to you sir, we could get access to such high quality code.

I have learnt a lot from your backend series , how the flow happens , how to think and not rush to code, how to standardize the code , how to abstract the common logic . This series has really increased my confidence. I really appreciate your effort and your valuable time in bringing us the valuable content and trying to make us better programmers. Thanks a lot Hitesh.

This is the best videos you can find on internet... University should also suggest this course students because they don't teach you like this

I have 1+ years of experience in mern but still watching your backend course, looking interested never watch this type of content on any platform. Awesome 🥰

Hi @hitesh, Thanks for this series. I love it :) . I wish you to plan for MERN interview guide series, it would help many ❤

1. Fetch req body 2. Check if user is exist. 3. Check user crendtails are correct. 4. Generate access & refresh token. 5. Save refresh token in DB 6. Return access & refresh token to client.

apka 1 hour ka video ho ya 3 hour ka maan hi nhi bharta sir esa lagta bass dekhe jao dekhe jao ..... you are such a great

1. validation of input fields 2. check if users credentials is present in db 3. compare passwords 4. generate access and refresh token 5. return response of access and refresh token in cookies thank you sir

Great to see u back! btw we gonna make frontend for this after this series? just a random thought came into my mind as u showed us the app in the very first.

The clarity i get from watching your videos is mind blowing.

Yes any other video will take lot of effort to reach this kind of dedication to give real real value to the community.

Sir ji after dhiwise and flutter flow like technology which can create flutter code very fast is learning flutter still good option I know a real developer is a person who focus on concept not on technology but I want your opinion... ❤

Aaj toh aapke comment targets ko double karke maanenge

Dear Hitesh Sir, thank you for the incredible Backend Series. Love this series. You are providing valuable knowledge and insights with industry grade practices.

Kisi tv series ka aisa intezar nahi Kiya jitna sir ka videos ka

Great explanation!! Such kind of tutorials are very, very hard to find and it will be game changer for the students and experienced persons as the core concepts have been explained in detail and with full explanation. Well done SIR

---Login TODOs // get username or email , password from user // Check for empty fields // Check if user exists or not // fetch user from database // compare saved password and input password // if credentials are correct generate access and refresh token So far I can only figure out this and itna sbh isliye likh paaya because peechli video se mst sikh kr aaya 3-4 attempt lge smjhne m

These videos have become an ADDICTION! Really a production grade code, I am guessing this can become a reference code.🙌

whoever is facing difficulty in understanding the video. Watch the video twice!. i faced the same problem as i was coding and watching the video at the same time , but i dedicated the second time to watch the video at 2x to understand each and every bit. now i have understood everything. thank you so much hitesh sir ♥ ♥

Waah sir, itna bada lecture!! Bohot achha laga pura dekh ke. kaafi kuch cheezein clear hui aur nayi nayi cheezein seekhne ko mili Thank you 😊

After watching the video twice, I found it extremely insightful. It provided a superb understanding of the topic

Good to see you again sir, I hope you are feeling better now. I wanna tell you something, your teaching skills are so polished and attractive. I hope you are always here to guide us.😇😇😇😇😇😇

best backend ever, i am blessed i found u in this early stage in my career.

This is backend serious help me lot of my current project and change my total coding approach.. Thank you sir.. give the lots of project related (setup) knowldage...

User ko login karne ke steps: 1. Get data from user. 1.5 . Validate the data as per your need. 2. Check if the user already exists or not , if not then give error 3.Save the email and password in jwt for further uses like not to ask the user to login again and again . Mujhe to itna hi knowledge hai abhi tak. Dhanyawad 🙏

6:18 1. Check if the user is not registered 2. Compare passwords in req body and db 3. Create an access token and refresh token using jwt 4. save token in cookie or DB as per requirements 5. Send response with tokens

Thanku so much sir ❤❤ aap hamare liye itne cast me hone ke baad bhi hamlog ko padha rahe hai love you sir 🌹🌹

Todo's for login 1. username/email input 2. password input 3. check user exit or not 4. if user exit assign token 5. redirect to home page

Hats off to you sir.. Standing throughout the videos, pain in eye, still dedicated to text us.. 😮 That's great. Thanku so much 👏👏

Steps to login 1. Getting username/email and password from user 2. Checking username/e-mail and password fields 3. Getting user info from db 4. Password checking 5. Generation of acces and refresh token 6. Send cookie

JavaScript, React & now Backend followed everything religiously and gained so much knowledge, Thank you Hitesh sir.

this was such deep and in depth lecture ,completed this in 2 days in 2 sitting ,each minute was worth it

Yes Sir, pura samjh me aarha hai. Ho hi nahi sakta hi aap samjhaye or hume samjh na aaye.. 🙏🏻🙇🏻‍♂

I never waited for any web series as i wait for next video of you lectures. Best course on youtube

I could never imagine such in depth information can be found so much easily, you are really great Hitesh sir!!

todos for a login user: 1) email and password ko pehle validate kro wrna error pass kro 2) uske bd check kro jo user ne email dia h kia exist bhi krta h ya nhi db me wrna error pass krwao 3) agar email h db me tw password ko compare karwao jo db me save h wrna invalid credentials ka error pass krwao 4) uske bd aek access token aur aek refresh token return kro user ko lekin dono tokens k secret key different rkh kr same nhi hona chaiye continue...

Nice video on how to use cookie, refresh token and access token Now it clear as crystal !!!

After a long time, nice to be back and continuing this series with you.

Thank you so much sir !!! feeling grateful to study from such a great teacher .💗💗💗

Sir , pain hua 2 baar dekhne me lekin maza aagaya

30:39 Yes sir samajh aa raha hai sir bahut ache se aap padate hai sir I sure that none one can become like you

thank you so much sir, your ability to impart knowledge with such passion and patience is truly commendable 🙏

Hats off to your sir. Having an amazing journey with you. Bht mza aa rha hai backend pdne mai. Hope to meet you soon sir❤

hi sir hope u r doing well , your efforts in this series are excellent honestly, I watched it twice and after completing whole series i will watch in one go thanks you so much Sir for this production grade series

i took sir mern stack boot-camp but believe me this series and way more better then whole boot-camp.even they do teach refresh token there so i'm relearning here again

Sir, feeling so lucky to be a part of this community.

Very well explained about the concepts of refresh and access tokens, GOAT @Hitesh sir. Learning from you i am becoming better developer.

Thank you so much, sir, for the excellent Node.js backend series! 🙏✨

1. validation of input fields (req.body such as email or username and password) 2. check if users credentials is present in database 3. compare and validate passwords using jwt and database 4. generate access with expiration 1 hr and refresh token expiration 1 day 5. return response of access and refresh token

For the first time, i have completed 1 hour long video in one sitting and completed in full while coding and understanding things properly. Thank you hitesh sir for making these topics so much engaging for us. Completed at 14 March 2024 5:50 pm

best ever Teacher with amazing communication skill.

Login Steps which came in my mind: 1.Take Input (credentials). 2.Validation ( fields are not empty , email is valid ,etc.). 3. Find user in our db by email or username. 4.Verify password. 5.Generate access and refresh token. 6.Redirect to Home page if you want. 7.Remove tokens and password from response. 8.Return response. after continue video I got to know that , I missed out to save my access token in my db, so another step. after step 5 , there'll be another crucial step "Send tokens in the form of cookies"

Nice to see you sir🙂thank you for all these types of content you are providing to us...🙂🙂

Thank you for explaining everything in such a great way

boht achhe se samjhaya apne, thanks

🌟🌟🌟🌟🌟 Thank you so much for creating and sharing this amazing content! 🙏 Your videos have been incredibly helpful and insightful. I appreciate the time and effort you put into each video to make it both informative and engaging. Keep up the fantastic work! Looking forward to more valuable content from your channel. 👏

@10:30 if we are looking for atleast one input from user that's username or email, than condition to throw error should be "&&'. If we use Or ("||") than it will throw error even though user has sent either of the options, i e. Username or email. Apart from that, thank you so much for this type of videos. 🙏🏼

todos 1)get email,password from the user 2)check if they are not empty 3)validate them with the existing user 4)send res accordingly

Today lecture is awesome. Maza Aajata s Hai sir aap ke Saath padhkar.

Great to see u are recovering fast

todo's-> get the user info from fronted(username,email,password) make a db call to find the user if the info is wrong or empty then throw error generate the refreshtoken and accesstoken, set duration for them

Acche content ko comment to banta hai 🤩🤩 Sir bas ase hi mast content deliver kariye ☺

Your Way of teaching always pull me to your channel

I love this man the way of teaching is on another level

get user details from the frontend or backend check if any field is not empty validate the credentials give by user check if the user exists or not generate access token for the user redirect user to the required page he wants to go home or admin...

todos for login user 1.get req from client 2.check if the user is exists 3.decode password and compare both passwords 4.if matches create a refresh token and access token 5. create a middleware to verify access token 6. function that assigns again access token

Aapka bohat hi intezar thaa Par aapne intezar ki ghadi ko khatm kiya aur aap wapas aa gaye🎉🎉🎉

Awesome teaching style !! Thank you sir

Your explanation is so good and clear . concepts are clear to understand ❤❤

seriously very nice content sir ..loved your teaching style 😍

6:11 take username email and password from req.body trim and check if all fields have proper value check if user exist or not if exist login the user and generate refresh and access token if not throw error

1. get credentials from the user/frontend 2. validate data/credentials 3. check for the user in DB with the username 4. compare the passwords after decrypting 5. generate an access token and refresh the token 6. send access token as a response

You are best teacher of web development❤

6:15 I think sir, step01 => get user's email id and password step02 => primary validation(empty field or not) step03 => check if user already exists then generate access and refreash token step04 => give the user accessability to log in step05 => remove the tokens from the field step06 => if user email and password not match route the user to the sing up page

Login user 1. get data available in req object from adding req.json() middleware 2. extract data and perform validation (frontend validation is recommended) 3. get user from database with same email trying to login 4. decrypt password bcrypt.compare and compare (we can also use an method written on user schema) 5. if password is correct create jwt and store it in req.user, which will give access to user from req object

I have gone through so many tutorials but never came accross such quality content, the thing is stuffs are not tough it's the instructors who decide wether it is going to be simple aur tough. You doing great job @chaiaurcode #chaiaurcode #backenddevelopment

Sir you are really Heart beat for developers ❤ you are Big great sir 😊

Ram Ram Sir G jwt token ka aisa use abhi tak nhi kiya tha,maja hi aa gya
