Sharing state between React components

use-between

When you want to separate your React hooks between several components it's can be very difficult, because all context data stored in React component function area. If you want to share some of state parts or control functions to another component your need pass It thought React component props. But If you want to share It with sibling one level components or a set of scattered components, you will be frustrated.

useBetween hook is the solution to your problem :kissing_closed_eyes:

import React, { useState, useCallback } from 'react';
import { useBetween } from 'use-between';

const useCounter = () => {
  const [count, setCount] = useState(0);
  const inc = useCallback(() => setCount(c => c + 1), []);
  const dec = useCallback(() => setCount(c => c - 1), []);
  return {
    count,
    inc,
    dec
  };
};

const useSharedCounter = () => useBetween(useCounter);

const Count = () => {
  const { count } = useSharedCounter();
  return <p>{count}</p>;
};

const Buttons = () => {
  const { inc, dec } = useSharedCounter();
  return (
    <>
      <button onClick={inc}>+</button>
      <button onClick={dec}>-</button>
    </>
  );
};

const App = () => (
  <>
    <Count />
    <Buttons />
    <Count />
    <Buttons />
  </>
);

export default App;

useBetween is a way to call any hook. But so that the state will not be stored in the React component. For the same hook, the result of the call will be the same. So we can call one hook in different components and work together on one state. When updating the shared state, each component using it will be updated too.
