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 mangement librares like Redux or MobX. This also makes Formik is easy to adopt incrementally and keeps bundle size to a minimum.
"Formik. All day. All long."
Ken Wheeler, Director of Open Source at Formidable Labs
"I can't believe people ever put forms in Redux, or did anything else other than this."
James Long, Creator of Prettier
Formik has been powering forms at The Palmer Group since 2016. Formik was open sourced in 2017 and is used by teams of all sizes.
