[6.12.0] - 2020-12-12

Changed

• When invoking reset({ value }) value will be shallow clone value object which you have supplied instead of deepClone.

// ❌ avoid the following with deep nested default values
const defaultValues = { object: { deepNest: { file: new File() } } };
useForm({ defaultValues });
reset(defaultValues); // share the same reference

// ✅ it's safer with the following, as we only doing shallow clone with defaultValues
useForm({ deepNest: { file: new File() } });
reset({ deepNest: { file: new File() } });

Added

• New custom hook useController: This custom hook is what powers Controller, and shares the same props and methods as Controller. It's useful to create reusable Controlled input, while Controller is the flexible option to drop into your page or form.

import React from 'react';
import { TextField } from '@material-ui/core';
import { useController } from 'react-hook-form';

function Input({ control, name }) {
  const {
    field: { ref, ...inputProps },
    meta: { invalid, isTouched, isDirty },
  } = useController({
    name,
    control,
    rules: { required: true },
    defaultValue: '',
  });

  return <TextField {...inputProps} inputRef={ref} />;
}
