useSecureLocalStorage

useSecureLocalStorage is a supercharged version of React's useState hook, designed to securely store and persist state in the browser's local storage with typescript support. So that, a user can make sure strictly typed data while storing or retrieving from local storage. Built on top of react-secure-storage, this library not only encrypts your data but also ensures strict typing and synchronization for the most up-to-date state.

Here’s an example of how to use useSecureLocalStorage in your React application:

};

const App = () => {
  const [apple, setApple] = useSecureLocalStorage<AppleType>("apple", {
    name: "Granny Smith",
    color: "green",
    isRipe: false,
  });

  const updateApple = () => {
    setApple({
      name: "Red Delicious",
      color: "red",
      isRipe: true,
    });
  };

  return (
    <div>
      <h1>Apple Storage</h1>
      <p>Name: {apple.name}</p>
      <p>Color: {apple.color}</p>
      <p>Is Ripe: {apple.isRipe ? "Yes" : "No"}</p>
