Dude! I watch A LOT of tutorials and this one was VERY good! No slow pace lingering or repetitions. Straight to the point and good, solid explanations. Very good job! Kudos!

I see a bunch of questions asking why you would need this when typescript already provides you with compile time type safety. Zod provides you with runtime type safety and is primarily for validating things you don’t control such as API input and form input validation. You already must validate these so having a library that lets you define your schema’s declaratively and derive your DTO types is awesome. It also lets you share the exact same validation logic between Frontend and backend by using same schema. Deriving new schema’s and their types from existing ones also really helps reduce validation logic and types you have to write. In many cases for example, the update schema will just be a partial create schema with added required if etc, which is like 2 lines of extra code with Zod for new schema and types. Your errors are also strongly typed.

Some people also validate API response, is it really good to also runtime validate API response on The Frontend?

Please post more typescript content. I really love it, thank you Kyle

Honestly Kyle the way your content has advanced my career, just wanted to say thanks 🙏🏾

Kyle, this video was great. I would love to see an example of using Zod with and ODM like Mongoose. Maybe a short or 5' video.

Kyle, thanks for this video! I only know of Zod by name and have seen examples of it being used in code. But after this crash course, I can see why it's praised! I look forward to implementing this library in future projects of mine.

hi anthony, I spotted you here

Thanks Kyle, great vid!! I love this new format. You rock!!

Amazing explanation. Clean and simple. Thanks !!!

thanks for this video, Kyle, it put my leg into the library within half an hour

After using Zoe minimally as part of tRPC for a while now I started adding it into my forms using React Hook Form. This video was super helpful in creating some more advanced schemas.

Thank you so much Kyle, awesome as always!

Amazing presentation, easy to watch and super useful. Great job!

This is a great tool, thank you for the clean and simple explanation

Great tutorial. Was really thinking of giving this Zod a try

Thanks a lot, Kyle. Your content means a lot for some of us.

Thanks a lot Kyle. This helped me fix a bug

you are amazing at explaining topics! it is insane

Thanks for the video! I really love Zod and I’m using it in recent projects, together with tRPC. Great to see all the abilities it has.

exquisite crash course, Kyle! I've been in python-land way too long and started to forget things lol

Hi Kyle, thanks for your dedication. I'm learning a lot of best practises thx to you. Im struggling a lot with the proper way to handle form validations with react. If you could explain how you consider the best way I would really appreciate.

great tutorial， thanks

great tutorial!

Tried Zod yesterday and I am glad that I don't need Typescript for it to run.

Hey. I'm just curious to know if it's possible to chain multiple regex expressions for the same input field and display different error messages .

One use-case I've not been able to figure out... how do you get a Zod schema for an existing TypeScript type? For example, if you're using a third party pacakage/library and you want one of your types to have a property that is of a type declared in that package?

today i literally started with zod for my express backend and here you come with an video💯💯

Do you have a recipe on how to validate type aliases using Zod? Instead of "z.string()" I would like to use my existing string type alias if possible. Any help would be appreciated! 🙏 Best, Benny

Thankyou awesome video I'll be using this immediately! :) Small error at 23:31 Object keys are always stored as strings in javascript. If you made the change you mention there actually would not be a parse error. Try console.log(z.record(z.string(), z.number()).safeParse({1:3})) --> { success: true, data: {1:3} } Only the Map and set types support other types as keys. I was super disappointed when recently discovering this, but luckily this was after Map and Set became available. I am still confused why typescript allows you to give Record anything other than string as first parameter. Maybe they were expecting a change to the standard?

❤ thanks for the video

Could someone share typical use cases for using Zod? I was thinking about maybe mapping response data? Im pretty new to typescript still and have done a little zod programming. Would be nice to know.

thank you for the video

Excellent 🎉

I'm curious is it possible to use the UserSchema as a map when fetching SQL data with the same name fields? I have experience doing this in C# but creating classes instead of objects.

Cool stuff bro

Hi kyle, big fan. Sometimes with your videos being long I feel like I won't be able to complete it. How about breaking the video into a playlist. That would really help me a lot. Thanks

Hello Kyle, great content. Just a concern... From the way you defined and explained sod, seems to be similar to class validator... Can you probably do a video showing the pros and cons of the two... I use class-validator because of validation and most importantly api documentation....

@d.sherman8563

It is similar, but takes a functional approach instead of OO. I think the strongest advantage it has is the ability to derive new validation schemas and their types from existing ones. All Zod methods are immutable so you can reuse existing schemas however you like. Say for example you have a UserSchema which has all fields mandatory including an id field. You can with just a few lines of code derive the validators and types for a CreateUserDTO schema by using UserSchema.omit({ id: true }), and an UpdateUserDTO schema with UserSchema.optional().required({id: true}) You also get strongly typed errors that are specific for the schema.

Any video on Valibot ? (ZOD's half bumdle size competition)

Vite is only to get TS working? But if you don't have Vite you can't do _import { z ] from "zod";_ right?

Looks like Yup but with better TS support and slightly more flexible I guess. I hope Formik will support Zod directly, without any adapters, just like Yup.

I work for one industry company and we use Zod everywhere. Super awesome, easy to use... Simply, you cannot resist using it once you try it. Even more, you can use it in react, vanilla js, aor eany odther js framework/library. I validate my forms on the frontend side when i do post requests. You can even validate reponses. Very powerful and awesome library!

Hey! Very cool. Care to share some typical use cases? You mentioned validate responses? Im struggling to understand whether zod is mostly used server side or client side. I initially thought it would be used to validate some request made by a client to the server. Some security stuff(?) i might be talking nonsense here.

Thanks!

Question: can‘t you just create a userModel for your user and then do „const user: userModel = {…} Because it will also check if you used the correct model properties and throw error if your value datatype doesn‘t match property datatype

This will work for object literals defined in your code. Zod is great for things like form validation, api input validation etc where you are not in control of what you’re validating.

Is there support to switch this Zod schema over to Mongoose?

How to began type on typescript if you dong like javascript?

I'm learning Zod and it is a very useful lib. I only miss an option to have rules for specific indexes (when z.array) or properties (when z.object). If someone knows how to make it, please share it with me, I'd appreciate it very much.

This is like the thriller movie of tech tutorials.

Great video, but I think it could have been made more structured so that we don't have to go back and forth between versions. It could have been better if the flow of the video does not include deleting all of the operators that was just discussed, in this way, it could have provided a better overview, and it would be easy to sum everything up. Nonetheless, learned a lot from this video!

Hi Kyle, I want to have a challenge on the frontend. I have around 10 years of experience. I have been watching your videos.

I do not care what validator to use as long as it have auto-generator tool. thats why i love json schema it became a standard and there are many tools for it

What if you ALREADY have a type/interface defined?

As it's purely JS based it should work for react native too because react native runs on JavaScript first which will interact with native Modules

Zod feels well designed and easy to use even without completely understanding TypeScript. Can we use Zod instead of Mongoose? And would that even be a good idea?

@DarkzarichV2

Mongoose and Zod have different goals and different use cases. First of all, Mongoose is an ODM and used to access documents in db using object oriented paradigm while Zod is a schema validation tool. While Mongoose can do schema validation it's not its main thing and Zod can't do absolutely the most of things Mongoose does so they're pretty much not interchangeable.

@@DarkzarichV2 Thank you. I left out the part where using Prisma + Zod (from the t3 stack) could probably replace Mongo + Mongoose for a fullstack project. I like the documentation from the former tools and not so much from the latter tools. Good docs matter a lot to me.

I love zod and this is a great video. I would recommend just staying away from TS enums btw. Also at the 13 mark you label the enums array as const and that's fine but personally for readability I would just say something like . const hobbies = z.enum(["hobby1", ....].

Nice , Useful and Simplified video as usual,🔥

have you used typia ? its 10000x faster than zod

With v3.20, there's a new .coerce pipe that's available, where you can attempt to coerce a value's data-type into something else. This could be useful where if you have an HTML form with a number input and you need to validation min/max. Using the .coerce pipe you can coerce the default input type of String into a Number and then validate it. It would look like this. z.object({ // at input (ie. evt.target.value) will be string since basically everything from an HTML input is string. count: z.coerce.number().min(18).max(200) });

Looks like Yup
