Basic Usage

Wrap your form with DataContext and then useBinding in every place you need to get or set value from DataContext.

Example:

import { DataContextProvider } from 'react-hooks-binding';

<DataContextProvider
  context={{
    payment: {
      cardNumber: '',
      expiry: '',
      cardCode: ''
    }
  }}
>
  <PaymentView />
</DataContextProvider>;

export default function PaymentView() {
  return (
    <>
      <CardNumber />
      <CardExpiry />
      <CardCode />
    </>
  );
}

import { useBinding, BindingMode } from 'react-hooks-binding/build';

export default function CardNumber() {
  let cardNumberBinding = useBinding({
    path: 'payment.cardNumber',
    mode: BindingMode.twoWay,
    convert: value => {
      let formated = payment.fns.formatCardNumber(value);
      return formated;
    },
    convertBack: (source, value) => {
      let cardNumber = string(value).replaceAll(' ', '').s;
      return cardNumber;
    }
  });

  return (
    <TextInput
      value={cardNumberBinding.value}
      onChangeText={rawCardNumber => {
        cardNumberBinding.setValue(rawCardNumber);
      }}
    />
  );
}
