Zod Makes TypeScript Even Better

Zod is amazing. It is not only an incredible validation library, but the direct interactions it has with TypeScript make it event better. Not having to define my types twice is a game changer and the simple yet powerful API of Zod is so nice. In this video I talk about what Zod is, show examples of how to use Zod, and talk about why it is so amazing.

I would love to see a full tutorial on Zod! Also, an overview on your thoughts of the T3 stack.

[@arno.claude]

I second this

[@zapfska7390]

I third the t3 stack

[@athulgeorge6744]

I 4th the T3 stack

[@nisargbhatt300]

I 6th this with Async validation with Zod (like unique username).

[@alexchang6367]

i 7th love to see this

[@papadavis47]

Well done, Kyle. I have heard of zod, but I have not used it yet. I appreciate this concise video of what it is. A full tutorial with a React Typescript project would be great. Thanks for your work!

[@remccs16]

This is great, thank you Kyle! I would most certainly watch a full tutorial on Zod!

[@MrSwingbop]

Full Tutorial is always welcome :D Thanks for all the precious tips!

[@codeNameMoose907]

Awesome! I never heard of Zod! But more importantly... hope you feel much better soon Kyle! Your followers will be here waiting; we won't ever leave you. Thanks for everything you do! Sending you and yours super healthy and happy healing vibes, Buddy! 😊

[@fotoflo]

Thank you for this great video! Wanted to note that Zod also offers a little bit of API around error messages as well.

[@abdirahmann]

OMG OMG OMG OMG please do a full tutorial on this one, this is going to simplify my data validation logic on my node server, i also just migrated everything to ts yesterday, how awesome, also, i checked out express-validator and i didn't like how it did validation using middlewares and stuff soo this is a GOD send. Thanks GOD and thanks to you too for letting us know. love ya :)

[@arunavabanerjee6103]

Hey Kyle, thanks for the video, zod seems super cool and I'd really like if could make a tutorial on it

[@samuelwittlinger7790]

Looks pretty good, personally I created a validator based on Joi which returns the object you are validating typecasted as the object type your validation schema is describing, which is a little more convenient than having to call infer every time.

[@anatolydyatlov963]

Yep, I've been using it for the past few months and it's a must-have for schemaless dbs.

[@johnjohn7023]

i was waiting for this. thank you so much!!! We want full tutorial!

[@jayliu5432]

Showing the form use case for Zod was super helpful. I finally get it!

[@boian-inavov]

I love how Zod has picked up popularity lately. I’ve been using it it for a while and it’s been amazing! You just forget about the cumbersome validation part and focus on building your business logic. Also the way it’ll give you a ready made object in the way you’d been expecting it is just god sent! Glad that more people are covering it 👏

[@BinaryReader]

Zod is no different to Yup, in fact, Zod is basically a clone of Yup with better static typing. Also, Zod is incredibly slow. Compare it to industry standard validators and it's like 300x slower to validate anything. You shouldn't be using Zod on the server side (it's that bad) The hype around Zod is real, but that doesn't make it good. It's just social media marketing and online influencers pushing it.

[@ElliottTheUnicorn]

thanks for the brief explanation. exactly what i was looking for 👍

[@souvlaki42]

Very cool library. I really like the idea of a tutorial about it.

[@arryaz051]

Great tool, I use it a lot in NodeJS HTTP APIs to validate requests to the server and get the TypeScript type too.

[@tsioryfitiavanaanhykrishna6992]

Aw longtime no see, I'm glad that u reach 1M sub ! Thanks for all your tutorials and keep up the good works !

Hey Kyle, Thank you for this video, i'd love to see a full tutorial on Zod!

[@anthonyribeiro3918]

I would love to see full tutorial too, your didatics is very good!

[@sohanbafna2282]

I am using NestJs heavily for most of my codebase I define DTO's and nest js frameworks helps me to validate each of objects/types for request I make. In that case i would not need this Before that we have been using JSON schema validators where we define schema and validate the DTO's But now zod is permutation and combination of all - like even loash functions are wrapped, this is super useful and must give a try Thanks for quick overview

[@akashsinha5148]

That would be wonderful 👍 please do a full tutorial. As your tutorials are small and feature packed.

[@vsabhishek1]

Thank you, you are awesome👌 in explaining new concepts👏👏. Yes i would love to see you cover a full tutorial on zod using typescript.👍👍

[@oleksandrluchytskyi6867]

Yes, please a video with most common recipes will be good to have 🤩

[@blockstarter4745]

Always great content chief (Y) . . . Keep it up

[@johnychinese]

Yep Kyle, We want a full tutorial, I love how you simplify these things but still show how valuable and powerful they are

[@LasgCe]

I remember watching the video 2 days ago and thinking, why would I ever need this .. Well, today I needed to create a very complex form validation and I gotta say, Zod is doing a great job so far

[@mind_of_a_darkhorse]

I am intrigued! So, please make a tutorial on this game-changing way of doing things!

[@mikehill1114]

I'm glad you said "comments below." I'm a full stack developer, but it wasn't until just now that I figured out where the KZbin comments were located ;)

[@RandomActsOfWil]

FULL TUTORIAL PLEASE!!!!! You are awesome!!!!

[@adisonmasih]

We really need a full tutorial! 🔥

[@martinpenev6750]

Hi Kyle Thx for showing us Zod, I really think it’s supercool! I was wondering: Which validation library have you been using before Zod?

[@focusroom_]

Great! want to learn more about this

[@sujoydutta920]

That would be really great to have a tutorial on Zod

[@twd2]

thanks ,Kyle a full tutorial would be greate 😍

[@nmanikiran]

would love to see a full tutorial on Zod! And also please compare with Joi, ajv, zod

[@BinaryReader]

Comparing Zod to Ajv would be embarrassing....for Zod >_>

[@aram5642]

Zod in a plain vanilla JS/TS project is definitely a win. No question about it. Would be interesting so see a video on how it integrates with framework like Angular and its built-in form validators.

[@ReconNite]

The problem I ran into with zod was that, not only was it super slow compared to other validators it was also very limiting as to what could be checked, or what could be coerced from one value to another. Although I still use it on some projects, I started to move over to superstruct for my more recent projects as it allows me to define custom refinements/coercions/types with little trouble. Of course this means that you lose the "built-in" or modular aspect of zod, superstruct makes it a lot easier for targeted validation.

[@BinaryReader]

Try TypeBox, it's based on industry standards and it's also 300x faster than Zod.

[@Jorgepr787]

Great intro to zod thanks!

[@jawadshaikh1745]

definitely would love to have a full tut on Zod

[@jtnovellis]

Yeah. I’d love to watch the full tutorial!

[@shivamsahil3660]

Hmm this seems more of a form validation library rather than improvement on typescript. Thanks a lot Kyle ❤️

[@nomadshiba]

cool, i had made something similar years ago it was returning correct type after parse also but this is more solid and better than my ancient prototype thingy of course defiantly will use it!

[@FamilyGuyVids11]

Great stuff. ill try it out

[@allirey6196]

it's very interesting not just for frontend form validation but also for backend API validation

[@morticie333]

Great, please do the complex tutorial! I am looking forward! :)

[@DillonRedding]

Super cool! This is like Joi, but specifically for TypeScript.

[@jimchapman4579]

Yes! Full tutorial please.

[@tonyg_nerd]

Kyle, thanks for this. I'm tooling up for projects with React, MUI, Redux, and have been looking into Formik which validates (primarily) with Yup. I'm not loving the Formik/Yup side, so it'll be nice to give Zod a spin, especially since it's TS-first, as am I. As someone else noted, my primary questions will be about custom rules, field/field comparisons, and async/sync server validations. Zod MUST perform here or I need to go with an established standard.

[@tonyg_nerd]

Looks like Zod is the winner with Hook Forms.

[@0xSLN]

great! full tutorial plz!!

[@ColinRichardson]

The problem I found with Zod is the transforms. It starts to blur the edges between validating and parsing. But my manager found a good library (I don't remember it's name for the top of my head) which uses the TS types and makes it a type validator at compile time, rather than runtime, using vite plugins. It seems like a better suit for us as we already have the types setup, rather than using Zod to Infer the types.

[@hienluong9273]

can you share what library you are using ?

[@MultiPoiu]

Erf, i'm sticking to AJV when doing api-first design and reusable component, because jsonSchema, even if it is a bit more tedious, it is reusable in all language, and can serve as first class API doc with swagger (jsonSchema are almost 100% compatible to swagger) And DTO with annotation are more readable for other stuff, I then use class-validator

[@nikhilverma4976]

Makes sense. JSON portability FTW

[@zhenglaowang8489]

I can't get over how clean your hair looks.

[@josecongo9453]

Please do a full Tuturial. I have a question, with zod do I still need create Interface(TS) for static checking? How can I reuse zod in multiple component(I thinking i react component). Thank you

[@arian5126]

Great, exactly what I needed in the right time for a React project but for someone who's worked with Angular FormBuilder (which is a built-in module), you'd know how Angular is underrated.

[@AmanSingh-px5if]

and exactly why react is so popular, not every project will need all the built in modules or even of the type that are baked in.

[@arian5126]

@@AmanSingh-px5if you don't have to use all built-in modules. The compiler removes unused modules from the bundle.

[@avneet12284]

Cool. Full tutorial would be great

[@dhaivathlal4870]

I'm about to do my first typescript form validation without any framework hence no framework provided form validation methods. This video just dropped right on time

[@saimrgondal2360]

I'd like a video comparing this with other form validation libs such as Joi. I;ve used Joi in the past and Im really curious to see if zod offers better usability. Thanks. Love your videos.

[@bouwensr]

Love a full tutorial especially with a form generated out of json data and field required based on a ‘complete switch’

[@_the_one_1]

You must be kidding! I was just trying to get deep with Zod and you posted a video! Great timing, thanks. I believe "everyone" would LOVE a full tutorial about Zod and why not... typing APIs both with static typing and validating the actual response

[@mrcookie97]

It can check if integer too that's quite nice

[@FatahChan]

Great video as always, can you make a video about PWA

[@SpaceGravy]

A comparison with yup would be appreciated!

[@chidimbamalu3490]

Good Video. Make a video on Zod like you did on Prisma

Magical video.

[@pomprocks]

You should show it with the same validation messages that your if/else validation has. Often certain messages need to be used, not just whatever messages your validation library produces.

[@nomiscph]

In angular they have forms with full typescript support 🎉 for everyone working with angular

[@vizunaldth]

Kyle - full tut like you did on prisma would be nice to watch

[@nickurchin9579]

At 1:25 ish I paused to read that Introduction off their site and once I read "The goal is to eliminate duplicative type declarations." - it clicked. As I'm on the tail end of the "learning" process, I hate getting comfortable with something (typescript in this case) only for a new/hot library to come along and improve it, because it also means I have yet another damn thing to learn before I feel ready to apply. However, I've actually recently run into that exact issue where I've had to declare the same type in two different places and it just felt gross, but I couldn't see a way around it; now we have Zod and that's awesome.

[@nickurchin9579]

@@kishirisu1268 Shhhh, Typescript can hear you. You're real too, Typescript, we promise (don't worry, it won't resolve).

[@rand0mtv660]

Yeah Zod is cool, but it also kinda depends what you are doing IMO. If you use Zod to validate endpoints that you create with tRPC, then it seems to be great. If you use it for validating forms on frontend with react-hook-form, then yup might just be slightly better. That's at least from my personal experience comparing these two. yup also has a nice Typescript experience and the infer type from schema like the z.infer you shown here. Zod isn't the first schema validation library to utilize Typescript, but it seems people act like it is :)

[@Zeee530]

In my previous project I used typescript, formik and yup for validation but Zod looks far more easier and manageable, I'll appreciate a full tutorial

[@danhphamthanh197]

I don't think so, Formik still make the form validate way more robust and manageble. Or maybe we can try Formik + Zod :D

[@odisclemons9700]

If you truly love Zod then KNEEL before Zod. Note: I'm 100% sure no one on the internet thought to make that exact same joke

[@diegomiyt]

Can i use zod to 'autommaper' ( like automapper from c# ) for convert one type to another? (Ex: IUserResponse from api to IUserState to use in React )

[@brunocapitelli7754]

Awesome vid! Even though Zod is awesome and pragmatical for type validation the only reason I still wouldn't add it to a backend project is that it's not an ORM as well, so using TypeORM is more of a gain even if the whole schema validation is more verbose. For frontend projects I feel like using it is not that worth it since I use Angular and things like FormBuilder along with classes/interfaces pretty much do the job for a frontend scope, leaving the hard validations for the backend as it should be. I can't help but feel like Zod has gained much popularity solely due to React and the culture of recurring to a lot of third-partys for specific objectives.

[@MrFelipefsf]

Thanks Kyle, I would like to watch a tutorial with NodeJs data validation
