Formik takes care of the repetitive and annoying stuff—keeping track of values/errors/visited fields, orchestrating validation, and handling submission—so you don't have to. This means you spend less time wiring up state and change handlers and more time focusing on your business logic.
No fancy subscriptions or observables under the hood, just plain React state and props. By staying within the core React framework and away from magic, Formik makes debugging, testing, and reasoning about your forms a breeze. If you know React, and you know a bit about forms, you know Formik!
Since form state is inherently local and ephemeral, Formik does not use external state management libraries like Redux or MobX. This also makes Formik easy to adopt incrementally and keeps bundle size to a minimum.
Formik comes with battle-tested solutions for input validation, formatting, masking, arrays, and error handling. This means you spend less time writing form code and more time building your next big thing.
With Formik, not only is the battery-pack included, but you're taking advantage of our community's collective learnings in security, accessibility, and user experience research.
