A Simple Example

Every Store is a function similar to a custom hook. In the body of a Store function, you can use any react hooks, for example, useState, useEffect, useRef.

export function FooStore() {
  const [x, setX] = useState(initial)
  return {
    x,
    setX
  }
}

Then, you can provide a store "instance" using Provider component.

import {Provider} from 'reto'

<Provider of={FooStore}>
  <App/>
</Provider>

By using the useStore hook, you can retrieve the store "instance" in components, and subscribe to its changes.

import {useStore} from 'reto'

const App: FC = (props) => {
  const fooStore = useStore(FooStore)
  
  function changeStore() {
    fooStore.setX(fooStore.x + 1)
  }
  return (
    <div>
      <button onClick={changeStore}>Change</button>
      {fooStore.x}
    </div>
  )
}

So when you click the "Change" button, the setX function of fooStore is executed, thereby triggers the update of state x and the rerender of App component. Everything is simple and straightforward.
