What are some examples of using Yup for schema validation?

Can you provide some examples of how to use Yup for schema validation?

Sure! Yup is a JavaScript schema builder for value parsing and validation. For example, you can create a simple schema for a user object like this:

import * as Yup from 'yup';

const userSchema = Yup.object().shape({
  name: Yup.string().required('Name is required'),
  email: Yup.string().email('Invalid email').required('Email is required'),
  age: Yup.number().positive().integer().required('Age is required'),
});

How do I validate an array of objects using Yup?

You can validate an array of objects by using the array() method. Here's an example:

const usersSchema = Yup.array().of(
  Yup.object().shape({
    name: Yup.string().required('Name is required'),
    email: Yup.string().email('Invalid email').required('Email is required'),
  })
);

Can Yup handle nested objects?

Yes, Yup can handle nested objects. You can define a schema for a nested object like this:

const profileSchema = Yup.object().shape({
  user: Yup.object().shape({
    name: Yup.string().required('Name is required'),
    address: Yup.object().shape({
      city: Yup.string().required('City is required'),
      zip: Yup.string().required('ZIP code is required'),
    }),
  }),
});
