Reduce Rerenders and make implementation like react-hook-form

[dakshsaraf]

🚀 Feature request

Currently I have a form with 100+ field and I have used FastField for every field as each field is independent of every other field. Still the form is extremely slow and I suspect it is because the form renders on every key stroke due to the changes in FormikProps.

I would suggest that an optional implementation can be created for users that need it. The rerendering can be made like react-hook-form where the form only rerenders when the user is done typing for a particular field

Current Behavior

Rerender for every keystroke

Desired Behavior

Renrender Once User is finished typing

Suggested Solution

Make implementation like react-hook-form

Who does this impact? Who is this for?

Impacts people trying to create forms with large number of fields where the optimization of FastField is not enough

use react hook form, formik isn't made for something like that

[bostrom]

@FilmCoder what is formik made for then?

We're experimenting with multiple methods for optimizing the internals of Formik to support this and plenty other scenarios. You can keep up with some ideas in several places like #2846 and #2931

These optimizations will require a major rewrite and major version bump.
