What are some good validation libraries for TypeScript?

There are several great validation libraries for TypeScript! Some popular ones include Joi, Yup, and class-validator. Each has its own strengths depending on your needs.

Can you tell me more about class-validator?

Sure! class-validator is a library that allows you to use decorators to define validation rules on class properties. It's particularly useful for validating data in frameworks like NestJS.

How does class-validator compare to Yup?

While class-validator uses decorators and is class-based, Yup is schema-based and allows for more flexible validation of objects. Yup is great for form validation, while class-validator is better for class instances.

Are there any performance considerations I should be aware of?

Yes, performance can vary based on the complexity of your validation rules and the size of the data being validated. It's a good idea to benchmark both libraries in your specific use case.
