Then we can add a conditional "error" class if there are any errors.We can check for errors by looking at the errors object (remeber how we calculated that object ourselves way back when). Notice that this message doesn't pop up automatically when the page loads.

The first option is creating our validate function.It wasn't that bad I guess, but with the Yup package, it gets all the more easy!Yup is the recommended way to handle validation messages. Now that we have the logic for creating error messages, we need to display them.If you're not very familiar with render props, I would take a second to check out Render Props Explained.In short, render props are used to pass properties to children elements of a component.This will allow us to enable/disable the submit button while the asynchronous login call is happening.

The Formik component uses render props to supply certain variables and functions to the form that we create.Think of initial values as setting your state initially. This callback will take two parameters, *and an object that we can destructure.The values represented the input values from your form.The form is pretty simple with two inputs (email and password), labels for each, and a submit button.We'll cover two ways to create these messages, one using Yup and one doing it yourself.The name can’t be empty and password can’t be less than 6 characters long. The user will not be forwarded to the next page until given values are correct.
