withFormContext

Allows you access to the form methods from a component that is nested lower in the structure than the declaration of the form.

Example

Typescript

import React from 'react';
import {compose} from '@truefit/bach';
import {withFormContext, UseFormReturn} from '@truefit/bach-react-hook-form';

type FormValues = {
  name: string;
  address: string;
  age: number;
};

type Props = {
  formContext: UseFormReturn<FormValues>;
};

const WithFormContext = ({formContext: {register}}: Props) => (
  <div>
    <input {...register('name')} />
    <input {...register('address')} />
    <input {...register('age')} />
  </div>
);

export default compose(
  withFormContext(),
)(WithFormContext);

Javascript

import React from 'react';
import {compose} from '@truefit/bach';
import {withFormContext} from '@truefit/bach-react-hook-form';

const WithFormContext = ({formContext: {register}}) => (
  <div>
    <input {...register('name')} />
    <input {...register('address')} />
    <input {...register('age')} />
  </div>
);

export default compose(
  withFormContext(),
)(WithFormContext);
