React Use Kana

A tiny React hook to build a better Japanese form. With this library, you can implement a feature to automatically fill in kana in your form.

Usage

Installation

npm install react-use-kana
# or
yarn add react-use-kana

API

useKana

This is the only one hook that react-use-kana provides.

• kana: string
  • A hiragana string that derived from inputs. You set this value to a text input for a kana field.
• setKanaSource: (value: string) => void
  • A function to let useKana hook know a new input value so that it can derive kana. In general, you call this function as onClick callback of a text input for a name field which probably has kanjis or non-hiragana characters.

Example

Let's see the following simple example.

import React from 'react';
import ReactDOM from 'react-dom';
import { useKana } from 'react-use-kana';

const App = () => {
  const { kana, setKanaSource } = useKana();

  return (
    <form>
      <div>
        <span>Japanese Traditional Form</span>
      </div>
      <div>
        <div>
          <span>Name</span>
        </div>
        <input type="text" onChange={e => setKanaSource(e.target.value)} />
      </div>
      <div>
        <div>
          <span>Name Kana</span>
        </div>
        <input type="text" value={kana} />
      </div>
    </form>
  );
};

ReactDOM.render(<App />, document.getElementById('root'));

react-use-kana doesn't provide features to handle your form's behavior (e.g. to set value to a component's state, to check if a field has been touched or not) because it's supposed to be agnostic about form library.
