What are some performance tips for using Formik?
To optimize performance in Formik, consider using the FastField
component for fields that don't depend on others.
What is the difference between Field and FastField?
Field
re-renders on every change, while FastField
only re-renders when its specific value changes, improving performance.
How can I manage form state efficiently?
You can manage form state efficiently by using Formik's setFieldValue
and setFieldTouched
methods to update specific fields.
Are there any best practices for validation?
Yes, use asynchronous validation and debounce your validation function to reduce the number of validations triggered on input.
