Formik VS React Hook Form Part I
Front End Engineers work a lot with forms and with the complexity of apps we need powered forms to help us managing the form state, form validation with nested levels, form verbosity.
Formik comes to solve all these problems.
Now we have a new library React Hook Form was released to compete.
Module Composition
React Hook Form has no dependencies
Controlled & UnControlled Component
Formik support Only Controlled Component but React-hook-form support both of them.
Controlled Component
is one that takes its current value through props and notifies changes through callbacks like onChange. A parent component "controls" it by handling the callback and managing its own state and passing the new values as props to the controlled component.
Controlled Component with RHF
Controlled Component with Formik
Uncontrolled Component
is one that stores its own state internally, and you query the DOM using a ref to find its current value when you need it.
feature | uncontrolled | controlled |
---|---|---|
one-time value retrieval (e.g. on submit) | ||
validating on submit | ||
conditionally disabling submit button | ||
several inputs for one piece of data | ||
dynamic inputs |
Re-Rendering
We want to avoid unnecessary re-render cycles as much as possible, as this could lead to major performance issues as an app grows.
Dependent Fields
With React Hook Form watch Function help you to watch specified inputs and return their values to determine what to render.
With Formik watching all fields enabled by default so you can remove or add fields depend on values prop.
Events
With React Hook Form Read Form Values inside events.
note: getValues() will not trigger re-renders or subscribe to input changes.
With Formik you can read form values with values prop.
