Simplify Form Validation with Formik & Yup

In the fast-paced world of web development, crafting forms is a common task. 📝 However, taming the beast of form validation can be a real challenge. 🧐 This is where the dynamic duo of Formik and Yup swoop in to save the day! 🦸‍♂️ In this article, let's embark on an exciting journey to simplify form validation using the magic of Formik and the armor of Yup! 🪄

Formik is like the superhero of form management in React applications. 🦸‍♀️ It swoops in to effortlessly manage form state, handle form submission, and gracefully interact with form fields. Formik is your trusty sidekick, reducing the tedious boilerplate code often associated with form handling. 💪

Yup is the guardian of data integrity, wielding the power of schema validation in JavaScript. 🛡️ It empowers you to define robust schemas for your data and offers a flexible yet formidable way to ensure your data adheres to these schemas. Yup is your loyal protector when it comes to client-side form validation, making it the perfect ally for Formik. 🤝

Before we dive into the action, let's equip ourselves by installing Formik and Yup in our project:

                                    
                                        npm install formik yup 
                                        # or 
                                        yarn add formik yup 
                                    
                                

Let's start our adventure by creating a basic login form with Formik. 🦸‍♂️ Here's a sneak peek at a simple example:

In this example, we've defined the form fields, initial values, and validation schema using Yup. We've also provided an onSubmit function to handle form submission.
