29,538 PointsHere some code that needs to go in the App component (in App.js) that will save your state in localStorage
componentWillMount() {
// Retrieve state from local storage
const data = localStorage.getItem("state");
// Parse JSON to JavaScript object
const state = JSON.parse(data);
// Set state to the retrieved JavaScript object
this.setState(state);
}
componentDidMount() {
// Add event listener that will execute code before page refresh
window.addEventListener("beforeunload", () => {
// Stringify the state object, so it can be saved as a text value
const data = JSON.stringify(this.state);
// Set localStorage item
localStorage.setItem("state", data);
});
}
Make sure you change your newGuestId method and work with state too, so you keep incrementing your GuestId count after page refresh :-)
