Question

How do I pass setState from parent to its child component using React Hooks? Code is provided:

App.js

export default App() {
  <Main>
    <Widget/>
  </Main>
}

Main.js

export default Main() {
  const [marketProducts, setMarketProducts] = useState([]);
  ...
  return 
    <DataContext.Provider value={marketProducts}>
      ...
      {props.children}
    </DataContext.Provider>;
}

Widget.js

export default Widget() {
  return <div>
    <NavComponent/>
    ...
  </div>
}

NavComponent.js

export default NavComponent() {
  // need setMarketProducts here but not sure how to bring from Main.js to here
  return <div>
    ...
  </div>
}

You can pass setMarketProducts down the chain as shown in example below. Other wise you can use some kind of store e.g. useContext or redux

export default App() {
  const [marketProducts, setMarketProducts] = useState([]);
  <Main setMarketProducts={setMarketProducts} marketProducts={marketProducts}>
    <Widget setMarketProducts={setMarketProducts}/>
  </Main>
}

export default Main({ setMarketProducts,marketProducts, ...props }) {

  ...
  return 
    <DataContext.Provider value={marketProducts}>
      ...
      {props.children}
    </DataContext.Provider>;
}


export default Widget({ setMarketProducts }) {
  return <div>
    <NavComponent setMarketProducts={setMarketProducts}/>
    ...
  </div>
}

export default NavComponent({ setMarketProducts }) {
  // need setMarketProducts here but not sure how to bring from Main.js to here
  return <div>
    ...
  </div>
}
