To view the documentation for the latest stable Formik version visit [jaredpalmer.com/formik/docs](https://jaredpalmer.com/formik/docs/overview)** --- Let's face it, forms are really verbose in [React](https://github.com/facebook/react). To make matters worse, most form helpers do wayyyy too much magic and often have a significant performance cost associated with them. Formik is a small library that helps you with the 3 most annoying parts: 1. Getting values in and out of form state 2. Validation and error messages 3. Handling form submission By colocating all of the above in one place, Formik will keep things organized--making testing, refactoring, and reasoning about your forms a breeze.
