It is difficult to me to believe that you provide these rich in quality tutorials for free. Cheers, Dave.

The best series I am LOVING this series thank you for your efforts Dave! I love Nestjs it's my main framework now

[@aaaajuuu8653]

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! :)

[@JonBrookes]

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

[@overrevvv]

Thank you for putting so much time and effort into this amazing playlist.

[@theybecameus]

thanks david❤

[@gururajmoger8649]

Please continue sir 🙏

[@viniciusmassari5503]

I'm really impressed how nestjs handles so much thing for us with a few lines of code.

[@kirillzlobin7135]

Who knows how often videos are released for this Nest JS playlist?) Waiting for the next one...

[@DaveGrayTeachesCode]

Just released the next one 1 minute ago. The release schedule has been every week but I took one week off for Thanksgiving.

[@girishgirijan9900]

Thanks

[@Peter-ck1qg]

Nice tutorial. Can we get a tutorial on microservices with express and nest after this series?

[@mikoajkaleta6856]

waiting for more episodes

[@danielouattara3857]

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" ?

[@codernerd7076]

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!

[@user-ih9wm5hu6f]

Can you explain me about hls in node js and front end i think this is so important

[@BrechtGijbels]

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.

[@podoprigoraisv]

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?

[@DaveGrayTeachesCode]

Yes, this is the standard structure from the documentation.

[@adrien437]

hi, are you going to make a tutorial about jwt authentication for nest?

[@DaveGrayTeachesCode]

Maybe a separate auth series for NestJS.

[@mrbilchalan]

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.

[@grant_vine]

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.

[@user-kz1om8oo8i]

can u share the name of icon extentions of your vs code??

[@fikreteliyev2266]

Hi Access token save in httponly cookie and refresh in redis This is possible?

[@user-ld1de1mc4h]

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?!?

[@DaveGrayTeachesCode]

Yes, new video tomorrow. To find out what's been going on, check out my community post on my channel.

[@codernerd7076]

Would it not better to use Zod for validation?

[@DaveGrayTeachesCode]

You can use Zod, but NestJS has validation pipes built-in.

[@thomaslefebvre5866]

isn't it better to use implements instead of extends ?

[@artyomtaranenko2267]

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.

[@Shriramkrishnhari]
