It is difficult to me to believe that you provide these rich in quality tutorials for free. Cheers, Dave.
So nicely explained without overcomplicating stuff
Thank you for putting so much time and effort into this amazing playlist.
The best series I am LOVING this series thank you for your efforts Dave! I love Nestjs it's my main framework now
Great series. I'm new to nestJS and have found these recent videos really useful. Thanks so much !
Hey Dave, thanks for the new Nest.js series. I actually just recently started learning Nest.js and its a big benefit for me having some actual examples from you. Thanks for that and i am looking forward to the next videos! :)
I really loved this nest js series. Thanks a lot sir.
If I didnt know what DTO was I certainly do now, thanks Dave, this is another brilliant video your explanations of setting up strong types makes the job a breezed
Woaahhhh!! Been using NestJs for few time now. But learnt something new today. Thankyou
I cant wait more for the next videos!
Great video as always!

Hello Dave, Happy New Year! I wish you the best ! Thank you for your teaching. It's great to learn with you Maybe that this is not the right place to ask... I find that if I make a "patch request" with an empty json object OR a json object with anything else than what describe in the "UpdateUserDto" class then it works. I know that there is the "extends PartialType(CreateUserDto)" on UpdateUserDto, meaning optional. Here my question: is there a way to model UpdateUserDto by saying: optional Yes ! but only among "name", "email" , "role" ?
I'm really impressed how nestjs handles so much thing for us with a few lines of code.
Nice tutorial. Can we get a tutorial on microservices with express and nest after this series?
Can you explain me about hls in node js and front end i think this is so important
Is there also a way to avoid the repetition of the roles in the method findAll within the file users.controller.ts? I was hoping it would be possible to use them from a DTO file, as they are defined there.
Oh no last video at comment time, home we soon get the next part, would be interested in a Nest.js API with a Next.js frontend project as well!
Thank you for the great tutorial. Do I understand right we have separate *.dto files due to convention one class per file instead to have one file users.dto.ts with all related classes?

Just released the next one 1 minute ago. The release schedule has been every week but I took one week off for Thanksgiving.
I have learned access token and refresh token technique from your Mern tutorial. Now, I am concerned about csrf token. The access and refresh token are all about authentication and authorization. I heard, when you send any form to server, try to validate csrf token also. My question is, is it necessary to use csrf token to be validate after applying your access token and refresh token technique. If it is then how to send and receive and validate it. Please consider to discuss it. Thank you.

CSRF is more relevant to Cross Site (I.e. separate domain/url) requests as a form of point in time trust validation between two remote parties, so more applicable to auth styles where you are redirected to an auth service that is separate from your app. Access to secure domain cookies wouldn’t work in that case - however, if your front end and your API are all served from the same domain (or domain suffix but that isn’t as secure on a cookie level) then CSRF isn’t really relevant as both that api and front end can actually read that cookie as they are on the same domain - hence no need for an out of band trust verification.
Hi Access token save in httponly cookie and refresh in redis This is possible?
Would it not better to use Zod for validation?

You can use Zod, but NestJS has validation pipes built-in.
Hey Dave, whats going on with this course? It's been almost 2 weeks since last video. Are you planning to continue on the series?!?

Yes, new video tomorrow. To find out what's been going on, check out my community post on my channel.
isn't it better to use implements instead of extends ?
Nestjs-zod looks better, smaller. What r u think about this?
@DaveGrayTeachesCode

I haven't looked at it although I know you can use Zod with NestJS.
