React Rerender Component

English｜繁體中文

Listen to state to rerender children components.

Install

$ npm i react-rerender-component

Import

import Rerender from 'react-rerender-component'

Example

function ReactiveCount ({ count }) {
  return <div>{count}</div>
}

function UnreactiveCount ({ count: initCount }) {
  const count = useState(initCount)[0]
  return <ReactiveCount count={count} />
}

In general, when the external state is passed to the ReactiveCount, it will be updated in time, but in UnreactiveCount exists a new state from the parent state, it can't rerender even if the external state is updated.

function App () {
  const [count, setCount] = useState(0)

  return (
    <div className="App">
      <button onClick={() => setCount(count + 1)}>Add</button>
      <ReactiveCount count={count} />
      <Rerender listener={[count]}>
        <UnreactiveCount count={count} />
      </Rerender>
    </div>
  )
}
