Next.js API Routes Validation with YUP

In this video we will add validation to our Next.js API Routes using YUP. In order to achieve that in a simple and reusable way we will create a validation middleware that uses YUP for schema validation.

Because we are using YUP, we can now share our validations across front-end and back-end. Form libraries like formik and react-hook-form work very well with YUP.

I hope you enjoy the video :)
