Below are the main reasons to recommend formik over redux form library,
- The form state is inherently short-term and local, so tracking it in Redux (or any kind of Flux library) is unnecessary.
- Redux-Form calls our entire top-level Redux reducer multiple times ON EVERY SINGLE KEYSTROKE. This way it increases input latency for large apps.
- Redux-Form is 22.5 kB minified gzipped whereas Formik is 12.7 kB
