[7.15.0] - 2021-09-05

Added

• useFieldArray new method replace()

const { control } = useForm({
  defaultValues: {
    test: [{ value: 'lorem' }, { value: 'ipsum' }],
  },
});
const { fields, replace } = useFieldArray({
  control,
  name: 'test',
});

const handleFullyReplacement = (): void => {
  // remove old and set fully new values
  replace([{ value: 'dolor' }, { value: 'sit' }, { value: 'amet' }]);
};

• Improved to not map types defined with interface.

import { useForm } from 'react-hook-form';

interface CustomValue {
  custom: string;
}

type FormValues = {
  fieldName: CustomValue;
};

const { formState: errors } = useForm<FormValues>({
  defaultValues: { fieldName: { custom: 'value' } },
});
