Zod is an amazing validation library that focuses on type safety and ease of use. I love Zod and feel that it makes TypeScript even better. It also makes working with user data incredibly easy and in this video I will show you everything you need to know about Zod.

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.

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?

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?

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 Жыл бұрын

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.

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!

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.

@DarkzarichV2 Жыл бұрын

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.

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) });

Typescript getting better is surely all it could do, it couldn't get any worse. I've been writing JavaScript since the beginning of it existing and since ES6 and then TS it's just a mess.

@veemacks7255 Жыл бұрын

That's an individual preference. Personally I prefer JS for informal things like greasemonkey scripts where I'll be the only maintainer and it's not production code. That doesn't mean I can't acknowledge that TS is a more complete and business ready language. But try migrating a large JS production codebase to TS in small segmental releases and see if you don't tear your hair out. The syntax for defining arguments for functions that take a variety of inputs is horrendous. Alan Turing would say it's undecipherable. It's easier when you're writing new code but still unpleasant.

@veemacks7255 Жыл бұрын

Wanting to not have to use TS at all. It maybe better in all measurable ways, just like the dev process at a large company is following agile processes. I still preferred my days in startups though and similarly prefer JS and specifically ES5. You can acknowledge that newer is objectively better but still long for the previous ways.
